method for estimating right ventricular volume by planes applicable to cross-sectional echocardiography: correlation with angiographic formulas.	right ventricular (rv) volumes determined by echocardiography were compared with those measured using established angiographic formulas. rv cast displacement volumes were first correlated with data derived from radiographic images of the casts corresponding to standard angiographic rv views. four established angiographic formulas (ferlinz, boak, fisher and thilenius) correlated well with cast volume, with the corrected prism method of fisher showing a best fit (r = 0.98, y = 1.1 + 0.9 x, standar ...	1985	4003302
hypersecretion of gastric acid in a representative finnish family sample.	to evaluate the family behaviour of acid secretion and particularly of 'hypersecretion', we have examined by pentagastrin test and direct vision gastric biopsy 342 subjects with a normal mucosa or superficial gastritis of the body mucosa, collected from a large family sample of the finnish population. acid output (ao) was expressed in terms of fat-free body weight (ffb), which eliminates the sex factor found by other expressions of ao. subjects with values above 1.0 mmol/h/ffb were considered 'h ...	1985	4023613
some goodness-of-fit methods for the poisson plus added zeros distribution.	methods for making inferences about the poisson plus added zeros distribution and the truncated poisson distribution are presented and illustrated with bacteriological data. some of the methods are designed for testing the compatibility of the zero frequency with the poisson distribution, whereas others are given for testing the goodness of fit for the truncated poisson. in particular, a modified form of the fisher index of dispersion is presented which is suitable for the truncated case. it is ...	1985	4004245
privman-fisher hypothesis on finite systems: verification in the case of the spherical model of ferromagnetism.		1985	9936381
correction of abnormal renal blood flow response to angiotensin ii by converting enzyme inhibition in essential hypertensives.	in 40-50% of patients with essential hypertension, a high sodium intake does not increase renal blood flow (rbf). these patients have been defined as nonmodulators because sodium intake does not modulate renal and adrenal responsiveness to angiotensin ii (aii). to define the role of aii in mediating this altered responsiveness, we assessed the effect of a converting enzyme inhibitor (enalapril) on rbf and its responsiveness to aii in 25 patients with essential hypertension--10 modulators and 15 ...	1985	2985655
relapsing ophthalmoparesis-sensory neuropathy syndrome.	we studied two patients with recurrent sensory neuropathy and weakness of extraocular muscles. there was electrophysiologic evidence of multifocal demyelination of sensory nerves, with relative sparing of somatic motor nerves. sural nerve biopsy in one patient showed segmental demyelination. we believe that these patients had an unusual form of inflammatory polyneuropathy--possibly a relapsing variant of the miller-fisher syndrome of acute idiopathic polyneuritis.	1985	2984602

biochemical and clinical evaluation of a new cellulose diacetate secondary filter for cascade filtration.	we have performed 24 cascade filtration treatments in 8 patients with hyperviscosity syndrome (2 cases), essential mixed cryoglobulinemia, post-hepatitic cryoglobulinemia, sjogrens disease, rheumatoid vasculitis, miller-fisher syndrome and chronic dysimmune polyneuropathy. new cellulose diacetate filters were employed, giving a satisfactory performance. at 1.5 l plasma treatment, the rejection rate for macromolecular plasma components was close to 90%, whereas albumin recovery was close to 70%. ...	1985	3921467
a stochastic simulation study on speciation by sexual selection.	a two-locus multi-allele sexual isolation model incorporating mutation and genetic drift which was first proposed by nei et al. (1983) is studied here. one locus controls the male mating character, and the other controls female receptivity. all females are assumed to have equal mating success. therefore, the frequencies of female receptivity alleles are changed by mutation, drift, and hitchhiking with male character alleles. without hitchhiking, development of sexual isolation between allopatric ...	1985	28563651
regulation of na,k-atpase biosynthesis in developing artemia salina.	regulation of the biosynthesis of the sodium- and potassium-activated adenosine triphosphatase (na,k-atpase) (ec 3.6.1.3) was studied in the developing brine shrimp, artemia salina. measurement of levels of the subunits of the na,k-atpase by radioimmunoassay indicated the presence of both alpha and beta subunits in undeveloped cysts and developing embryos prior to the appearance of enzymatic activity. the quantity of each subunit increased dramatically between 8 and 24 h of development and then ...	1986	3001068
a case of brainstem encephalitis with ct scan abnormality mimicking fisher syndrome.	a 7-year-old boy with brainstem encephalitis is described. he was drowsy in the acute phase. csf showed pleocytosis without elevated protein. eeg showed diffuse slow wave activity during wakefulness. ct scan disclosed a low density abnormality in the basal ganglia area, which disappeared as the patient recovered. the clinical signs, ct scan abnormality and eeg findings suggest that this case is not a variant of the guillain-barré syndrome but is brainstem encephalitis mimicking fisher syndrome.	1986	3799923
[combination therapy (hypervolemia, fluosol-da 20%, hypertension) in the treatment of symptomatic vasospasm].	combination therapy of (1) hypervolemia with albumin (1 g/kg/day), (2) artificial blood substitute (fluosol-da 20%, 10 ml/kg/day) and (3) induced hypertension was performed for the treatment of symptomatic vasospasm. outcome was compared between thus treated patients (treated group) and those without specific treatment (non-treated group) in (1) 30 patients presenting with vasospasm who were planned to undergo delayed operation (delayed operation group), (2) 23 patients undergoing early operatio ...	1986	2419780
using categorical variables in discriminant analysis.	three methods of transforming unordered categorical response variables are described. one is a method using dummy variables. the second method, in which all categorical variables are analyzed simultaneously, is based on an eigenanalysis of frequency patterns scaled relative to within-groups variance, jointly developed by j. e. overall and j. a. woodward. with the third method, independently developed by r. a. fisher and h. o. lancaster, each categorical variable is analyzed separately with scale ...	1986	26828223
fisher renormalization of the critical behavior in the random-field problem.		1986	9939517
carbonic anhydrase inhibition and cell volume regulation in necturus gallbladder.	gallbladder epithelial cells transport salt and water isotonically as the renal proximal tubule. the cells also have the property of regulating their cell volume in response to osmotic stress (fisher et al. 1981, persson & spring 1982, fisher & spring 1984, foskett & spring 1985). the volume-regulating phenomenon is the result of a balance between cell uptake of salt and water at the luminal membrane and exit at the basolateral membrane. different properties regarding volume regulatory increase ...	1986	3811979
toluidine blue in the detection of perineal lacerations in pediatric and adolescent sexual abuse victims.	posterior fourchette lacerations are suggestive of sexual assault, and toluidine blue dye has increased the detection of these lacerations in adult rape victims. this study investigated the use of toluidine blue dye in the pediatric (0 to 10 years) and adolescent (11 to 18 years) patients to detect posterior fourchette lacerations in sexually abused and control populations. application of toluidine blue dye increased the detection rate of posterior fourchette lacerations from 4% (1/25) to 28% (7 ...	1986	3786029

private alleles in a partially isolated population. ii. distribution of persistence time and probability of emigration.	two diffusion limits were derived from a discrete wright-fisher model of migration, mutation, and selection with an arbitrary degree of dominance. instantaneous killing of the process due to emigration of a mutant leads to one of two diffusion processes with a killing term. one (weak gene flow) is the boundary case of the other (strong gene flow), which can cover a wide range of gene flow. the diffusion process subject to strong gene flow is similar to that studied by s. karlin and s. tavaré (19 ...	1986	3787501
token swap test of significance for serial medical data bases.	established tests of statistical significance are based upon the concept that observed data are drawn randomly from a larger, perhaps infinite source population. the significance value, p, is the probability that the observations are drawn from a source population satisfying the null hypothesis; if p is small enough (less than 5 percent, 1 percent, etc.), then the null hypothesis is rejected. serial medical data bases, such as a hospital clinic intake or autopsy case accessions, often do not hav ...	1986	3511687

significant increase in immunosuppressive acidic protein (iap) in serum of patients with multiple sclerosis and other inflammatory neurological disorders.	iap, a type of alpha 1-acid glycoprotein, is mainly produced by macrophages when stimulated in the presence of circulating immune complexes or some inflammatory substances. we assayed the serum levels of iap by a single radial immunodiffusion method. the normal level of iap is below 500 micrograms/ml (385 +/- 73). in multiple sclerosis patients, however, iap increased during exacerbation (630 +/- 191) and decreased during the inactive stage (433 +/- 170). eighty-five percent of patients with neu ...	1986	3772394
the assessment of denial and physical complaints: the validity of the hy scale and associated mmpi signs.	little and fisher (1958) have demonstrated that the mmpi hysteria (hy) scale consists primarily of items that address the denial of psychological problems (the dn scale) and items that involve the admission of physical problems (the ad scale). the traditional interpretation of an elevated hy score implies that both dn and ad subscales are elevated significantly. using samples of psychiatric (n = 1,246), medical (n = 330), and chronic pain patients (n = 126), the effectiveness of the hy scale and ...	1986	3760208
normal-pressure hydrocephalus. onset of gait abnormality before dementia predicts good surgical outcome.	in 1977, fisher reported that in patients with possible normal-pressure hydrocephalus (nph), if the gait abnormality preceded dementia, surgery usually had a favorable outcome and vice versa. we studied this finding in 21 patients shunted for possible nph. by evaluating serial videotapes of gait, neuropsychological tests, and katz index ratings, preoperatively and at approximately two months and six months postoperatively, we judged 16 patients improved. in the improved group, the families repor ...	1986	3741212
[the double pontine lesion of fisher].	c. miller fisher described separately two pontine syndromes, that he called "the one-and-a-half syndrome" and "ataxic hemiparesis". the authors report the case of a woman who developed simultaneously the two syndromes, caused by a stroke of pontine localization, and comment about the structures involved by the lesion.	1986	3593035
chronic inflammatory polyradiculoneuropathy with ophthalmoplegia.	we report a case of chronic progressive inflammatory polyradiculoneuropathy with a subacute exacerbation that included ataxia, tendon areflexia, ptosis, and ophthalmoplegia. spinal fluid protein was elevated and electrophysiological studies revealed a demyelinating neuropathy. this case suggests a continuum between chronic inflammatory polyradiculoneuropathy and the miller fisher variant of acute inflammatory polyneuropathy.	1986	2946724
sex ratios in geographically structured populations.	in his book on sexual selection (1), darwin documented evidence that the primary sex ratio (the proportion of males at conception) is about 1/2 in a wide variety of species. otherwise, he explained, a newly conceived member of the rare sex will, on average, have more offspring than one of the common sex, since each offspring has one mother and one father; thus there is frequency-dependent selection in favour of parents producing the rare sex. darwin formulated this explanation in the first editi ...	1986	21227776
clinical significance of serum and csf findings in the guillain-barré syndrome and related disorders.	clinical data and the serum and cerebrospinal fluid (csf) findings of 71 patients with guillain-barré syndrome (gbs), 7 with fisher syndrome and 24 with chronic inflammatory polyradiculoneuropathy (cip), were analysed. isoelectric focusing of serum and csf together with different formulae and diagrams were applied to study blood-csf barrier (bcb) function and possible intrathecal igg synthesis. the csf total protein concentration and its igg percentage depended mainly on the degree of bcb damage ...	1986	3746360
elderly listeners' estimates of vocal age in adult females.	the purpose of this study was to provide data on the ability of elderly listeners to estimate the age group of women (25-35, 45-55, 70-80) from phonated and whispered vowel productions. further, comparisons were made between the performance of these elderly listeners and results for young listeners reported previously [s. e. linville and h. fisher, j. acoust. soc. am. 78, 40-48 (1985)]. tape recordings of whispered and normally phonated /ae/ vowels were played to 23 elderly women for relative ag ...	1986	3745688
the effectiveness of citric acid as an adjunct to surgical re-attachment procedures in humans.	the purpose of this study was to clinically evaluate the effect of citric acid on re-attachment and re-adaptation in conjunction with periodontal surgery. a split-mouth design was used in 10 patients involving 30 quadrants of surgery. a total of 120 teeth were treated. each quadrant consisted of at least 2 teeth from cuspid to second molar. one quadrant was treated with a modified widman flap alone while the root surfaces of the contralateral side were also treated with a 3 min application of ci ...	1986	3531246

a case of recurrent idiopathic ophthalmoplegic neuropathy (miller fisher syndrome)		1986	3701363
a concentration of fucosylated glycoconjugates at the base of cone outer segments: quantitative electron microscope autoradiography.	rod photoreceptors show a discrete band of labeled molecules at the outer segment base shortly after the administration of radioactive protein precursors (young, 1967). the band signifies the insertion of radiolabeled protein, primarily opsin, into rod disc membrane (basinger, bok and hall, 1976). in contrast, the autoradiographic labeling pattern in cones is characteristically diffuse (young, 1971), although cones as well as rods are now thought to replace their disc membranes continually (ande ...	1986	3709697
perineal effects of postoperative treatment for adenocarcinoma of the rectum.	nine (4%) first recurrences that involved the perineum were identified in a randomized study of 202 patients treated by no further therapy, chemotherapy only, radiotherapy only, combined radiotherapy and chemotherapy, following complete surgical excision of adenocarcinoma of the rectum. six of these were in unirradiated patients and in two of the three irradiated patients the perineum was included in the treatment volume. eight of the nine patients were male and all nine had received abdominoper ...	1986	3949566
acute bilateral ophthalmoplegia: 60 cases.	of 60 patients with acute bilateral ophthalmoparesis, the cause was within the brainstem in 18 (pretectal infarct, phenytoin toxicity, and wernicke's syndrome), in cranial nerves in 26 (guillain-barré or fisher syndrome, tuberculous meningitis), within the cavernous sinuses in 8 (tumors or infection), and at the myoneural junction in 8 (myasthenia or botulism).	1986	3945401

acetylation phenotype and hepatotoxicity in the treatment of tuberculosis in children.	we studied the relationship between acetylation phenotype and the appearance of biochemical and clinical signs of liver damage in 73 tuberculous children treated with isoniazid and rifampin. no significant differences were found with respect to the distribution of acetylation phenotype between tuberculous patients and a control group consisting of 256 children. hepatotoxicity manifested in 27 cases (37%), of which only five (7%) had clinical signs. application of the fisher exact probability tes ...	1986	3487069
mechanism of inhibition of rtem-2 beta-lactamase by cephamycins: relative importance of the 7 alpha-methoxy group and the 3' leaving group.	cefoxitin is a poor substrate of many beta-lactamases, including the rtem-2 enzyme. fisher and co-workers [fisher, j., belasco, j. g., khosla, s., & knowles, j. r. (1980) biochemistry 19, 2895-2901] showed that the reaction between cefoxitin and rtem-2 beta-lactamase yielded a moderately stable acyl-enzyme whose hydrolysis was rate-determining to turnover at saturation. the present work shows first that the covalently bound substrate in this acyl-enzyme has a 5-exo-methylene-1,3-thiazine structu ...	1986	3487346
the galaxy luminosity function and the redshift-distance controversy (a review).	the mean relation between distance and redshift for galaxies is reviewed as an observational question. the luminosity function for galaxies is an important ingredient and is given explicitly. we discuss various observational selection effects that are important for comparison of the linear and quadratic distance-redshift laws. several lines of evidence are reviewed, including the distribution of galaxy luminosities in various redshift ranges, the luminosities of brightest galaxies in groups and ...	1986	16593693
correlation of 1a afferent conduction with the ataxia of fisher syndrome.	the pathophysiology of the ataxia in fisher syndrome (the syndrome of acute ophthalmoplegia, ataxia, and areflexia) has been attributed to both peripheral nervous system pathology and cerebellar system dysfunction. pathologic studies have demonstrated no consistent central nervous system abnormalities. we present a case in which abnormalities of 1a sensory conduction were found to correlate directly with the degree of ataxia, without impairment of motor or cutaneous sensory conduction. we propos ...	1986	3713737
the genetics of quantifiable homeostasis: i. the general issues.	some fundamental issues in developing the quantitative genetics of heritable traits are addressed. such a trait must be capable of being represented as a quantity. choice of the metric can be satisfactorily made only in the light of some insight into the nature of the trait and what its revealing characteristics may be. this insight is likely to change as more is known about the process, so the form and detail of the analysis is not static but perhaps continually evolving. much has been made out ...	1986	3706403
[electron microscopic microanalysis of prickle cell carcinoma, basaloma, malignant melanoma and normal skin].	emma has been used in dermatology since 10 years. in 1981, fisher established the cu/zn index as a parameter for the prognosis of malignant melanoma. we tested the emma technique as a means to determine the cu/zn index in basal cell carcinoma, squamous cell carcinoma, malignant melanoma, and normal skin. our preliminary conclusions are: emma may be useful to determine the cu/zn index in skin tumors; it is possible to obtain useful data from tumors already fixed in paraffin; (c) the highest cu/zn ...	1986	3716530

ntp toxicology and carcinogenesis studies of benzyl acetate (cas no. 140-11-4) in f344/n rats and b6c3f1 mice (gavage studies).	benzyl acetate, a water-white liquid with a pear-like odor, is a natural constituent of several essential oils and flower absolutes extracted from jasmine, hyacinth, gardenia, tuberose, ylang-ylang, cananga, and neroli. commercial benzyl acetate, a liquid prepared synthetically from benzyl chloride, acetic acid, and triethylamine is used primarily as a component of perfumes for soaps and as a flavoring ingredient. this compound is practically insoluble in water but is miscible in alcohol and eth ...	1986	12748678
effect of age on beta adrenergic relaxation of the rat jugular vein.	using the fisher 344 rat model and blood vessel ring segments in vitro, age-related changes in vascular beta adrenergic relaxation were investigated. in the pulmonary artery and aorta, maximum isoproterenol-induced relaxation and sensitivity to isoproterenol declined from 1 to 3 months of age confirming previous reports. in animals 6 months of age, these vessels no longer relaxed to isoproterenol. in the jugular vein, in which beta adrenergic mechanisms predominate, there was no change in maximu ...	1986	3001294
structural analysis and immunogenicity of pseudomonas aeruginosa immunotype 2 high molecular weight polysaccharide.	we analyzed high molecular weight polysaccharide (ps) from the fisher immunotype 2 (it-2) strain of pseudomonas aeruginosa for molecular composition and structure, then determined its immunogenicity in healthy adults. the ps was composed of 2-acetamido-2,6-dideoxygalactose (n-acetyl fucosamine) and glucose in a molar ratio of 2:1. structural analysis by carbon-13 and proton nuclear magnetic resonance confirmed that the high molecular weight ps was structurally identical to that of the o-specific ...	1986	3080477
adherent spleen cell production of e series prostaglandins in rats bearing variants of the r3327 dunning prostatic adenocarcinoma: effect of cyclophosphamide.	prostaglandins of the e series (pge) have been implicated in many facets of immunoregulation, as well as having a possible role in metastatic dissemination. variant sublines of the dunning r3327 rat prostatic adenocarcinoma, differing in growth rate, hormonal responsiveness and in propensity for metastasis, were carried in fisher x copenhagen f1 animals. adherent spleen cells were assayed in vitro for their ability to convert arachidonic acid to prostaglandins of the e series. these glass adhere ...	1986	3088126
[ir-gene control of rat t-lymphocyte proliferation in response to ig allotype].	antigen-induced t-cell proliferation in vitro was adapted to the estimation of antiallotypic response to igk-ib immunoglobulin k chain allotype of msu/b and fisher rats in wag, august and fi (wag x august) rats. august and fi rat t lymphocytes responded to igk-ib alloantigen with stimulation indexes (si) 3.8-5.0 (high responders), while wag rat t lymphocytes showed practically no response (si 0.9-1.8--low responders). these results correlate well with our previous findings of ir-gene-controlled ...	1986	3089344
polyclonal and monoclonal antibody therapy for experimental pseudomonas aeruginosa pneumonia.	a human immunoglobulin g preparation, enriched in antibodies to lipopolysaccharide (lps) pseudomonas aeruginosa antigens (pa-igiv) and murine monoclonal antibodies (mab) to p. aeruginosa fisher immunotype-1 (it-1) lps antigen and outer membrane protein f (porin), were evaluated for therapeutic efficacy in a guinea pig model of p. aeruginosa pneumonia. the concentration of antibodies to it-1 lps was 7.6 micrograms/ml in pa-igiv and 478 micrograms/ml in the it-1 mab preparation. no antibody to it- ...	1986	3093385
influence of complex charge and size on the uptake of 99mtc-diphosphonates in osteogenic tissue.	the biodistributions of six chromatographically pure 99mtc-hedp complexes have been determined in soft tissues, normal bone and osteogenic lesions (induced with a walker 256 tumor) in fisher 344 rats. the physical properties of each 99mtc-hedp complex including anionic charge, partial molar volume, molecular weight and spectral characteristics are known; thus allowing structure-activity relationships to be drawn. the results indicate that the smallest, low charged, mononuclear 99mtc-hedp complex ...	1986	3095270
control of phosphorylase kinase in the isolated glycogen particle by ca2+-mg2+ synergistic activation and camp-dependent phosphorylation.	the isolated glycogen particle provides a means to examine the regulation of glycogen metabolism with the components organized in a functional cellular complex. with this system, we have studied the control of phosphorylase kinase activation by ca2+ and camp. contrary to a previous report (heilmeyer, l. m. g., jr., meyer, f., haschke, r. h., and fisher, e. h. (1980) j. biol. chem. 245, 6649-6656), phosphorylase kinase became activated during incubation of the glycogen particle with mgatp2- and c ...	1986	3007504
hcg-induced tsh receptor activation and growth acceleration in frtl-5 thyroid cells.	our previous studies have indicated specificity cross-over between lh/hcg and the tsh receptor. we have now analyzed the ability of the tsh-dependent fisher rat thyroid cell line (frtl-5) to proliferate in a differentiated state under the influence of highly purified hcg (hcg-cr121). tsh receptor activation and growth induction were observed after 7 days suspension from a tsh-induced growth phase. the effect of 10 ug hcg-cr121 was equivalent to 500 +/- 43 (mean +/- sem) uiu of human tsh (2nd irp ...	1986	3009152
human immunodeficiency virus seroprevalence in pediatric patients 2 to 14 years of age at mama yemo hospital, kinshasa, zaire.	seroprevalence to human immunodeficiency virus (hiv) was determined among 368 children 2 to 14 years of age who were admitted to the pediatric service at mama yemo hospital in kinshasa, zaire. forty (11%) of these patients and only one (1%) of 92 healthy siblings of these patients were hiv seropositive (chi 2 = 8.68, p less than .01). seropositivity was associated with previous hospitalization, receipt of a blood transfusion prior to the current hospitalization (odds ratio 3.1; 95% confidence in ...	1986	3020492
cross-reactions of lipopolysaccharides of pseudomonas aeruginosa in antipneumococcal and other antisera.	lipopolysaccharides of the seven fisher immunotypes of pseudomonas aeruginosa gave cross-precipitation in many antipneumococcal sera. the reaction of pseudomonas type iv in type 25 antipneumococcal serum was immediate and heavy: 93 micrograms of antibody nitrogen per ml. correlations are described, mainly between the structures of the o-chains of the immunotypes and their specificities as shown by the cross-reactions.	1986	3096896
a myosin heavy-chain-like polypeptide is associated with the nuclear envelope in higher eukaryotic cells.	a high molecular weight polypeptide, identified as an atpase subunit by direct ultraviolet photoaffinity labeling, has been shown to be a component of nuclear envelope-enriched fractions prepared from a variety of higher eukaryotes (berrios, m., g. blobel, and p. a. fisher, 1983, j. biol. chem., 258:4548-4555). in rat liver as well as drosophila melanogaster embryos, this polypeptide appears to be a form of myosin heavy chain. this conclusion is based on both immunochemical and immunocytochemica ...	1986	2943745
polysaccharide surface antigens expressed by nonmucoid isolates of pseudomonas aeruginosa from cystic fibrosis patients.	we tested nonmucoid pseudomonas aeruginosa isolates obtained from cystic fibrosis (cf) patients for the expression of lipopolysaccharide (lps) serotype antigens, serum sensitivity, and production of mucoid exopolysaccharide (mep). when all nonmucoid isolates were compared with a set of random mucoid isolates, 20 of 52 (38%) nonmucoid isolates were typable and serum resistant, compared with 13 of 51 (24%) mucoid isolates (p = 0.16 by chi-square analysis). however, nonmucoid strains from cf patien ...	1986	2943759
mechanical and histochemical characterization of skeletal muscles from senescent rats.	maximal shortening velocity (vmax) and isometric tension (po) were measured in living fiber bundles and skinned fibers from extensor digitorum longus (edl) and soleus (sol) muscles of young adult (9 mo) and senescent (30 mo) fisher 344 rats. the fiber type composition of each muscle preparation was determined using myosin (m)-atpase histochemistry. vmax, determined by the slack test method, was unchanged in the edl but was increased in the sol muscles of young adult vs. senescent rats. velocitie ...	1986	2944390
the capability for regulation of insulin secretion by somatostatin in purified pancreatic islet b cells during aging.	pancreatic islet b cells from sprague-dawley and fisher 344 rats aged 3-27 months were separated from a and d cells by centrifugation over a linear percoll density gradient, and incubated in vitro with various concentrations of glucose and somatostatin. elevation of glucose concentration in the incubation medium from 2.6 to 16.7 mm provokes an insulin secretory response that is independent of rat donor age. inhibition of the insulin secretory response by somatostatin is independent of rat donor ...	1986	2870220
the effects of reserpine and haloperidol on tyrosine hydroxylase activity in the brains of aged rats.	many neurotransmitter systems appear to be altered with aging. the effects of aging on the regulation of tyrosine hydroxylase, the rate-limiting enzyme in the synthesis of catecholamines in the brain has been examined. the endogenous basal activity of tyrosine hydroxylase was lower in the hypothalamus of 24 month old fisher 344 rats than in the hypothalamus of 3 month old or 6 month old animals. there was no difference in the basal activity of tyrosine hydroxylase in the locus ceruleus, frontal ...	1986	2874461
the dynamics of phase partition. a study of parameters affecting rat liver organelle partitioning in aqueous two-polymer phase systems.	separation of subcellular organelles by two-phase partition is thought to reflect differential partition of the organelles between the two phases or between one of the phases and the interface. studies by fisher and colleagues [fisher & walter (1984) biochim. biophys. acta 801, 106-110] suggest that cell separation by phase partition is a dynamic process in which the partition changes with time. this is mainly due to association of the cells with sedimenting droplets of one phase in the bulk of ...	1986	2874790
[neuromediator binding to receptors in the rat brain. the effect of chronic administration of ginkgo biloba extract].	the present data confirm the results of others that post-synaptic receptor changes may contribute to the decline in brain cholinergic function in ageing and dementia. we have also shown that chronic oral treatment with an extract of gingko biloba increases the apparent muscarinic receptor population in the hippocampus of the aged fisher 344 rat. the possible effect on (3h) kainic acid binding to the kainate-excitatory amino acid site is also interesting because of the proposed association of neu ...	1986	2878427
friend virus-specific cytotoxic t lymphocytes recognize both gag and env gene-encoded specificities.	we have constructed a series of "synthetic" target cell lines for an analysis of the specificity of anti-friend virus (fv) ctl. our results show that murine h-2 genes and individual retroviral genes can be stable expressed in fisher rat embryo (fre) cells, and that their products have the potential to form target structures recognized by mouse ctl. cells expressing h-2db and either the env or gag genes of one component of fv, helper friend murine leukemia virus (fmulv), were lysed by anti-fv ctl ...	1986	2425028
studies on high-affinity [3h]substance p binding sites in bovine pineal gland.	the presence of substance p in numerous mammalian pineal glands prompted us to search for its binding sites in the bovine pineal gland. the binding assays to pineal membrane were carried out in polypropylene microcentrifuge tubes in a final volume of 500 microliters of 50 mm tris-hcl buffer (ph 7.4) containing aliquots of 200-500 micrograms protein, 0.02% bsa, 6 micrograms/ml chymostatin, 4 micrograms/ml leupeptin, 40 micrograms/ml bacitracin, 5 mm mncl2, and 50 microliters of [3h]substance p (3 ...	1986	2430788
enhancement of aldehyde dehydrogenase activity in human and rat hepatocyte cultures by 3-methylcholanthrene.	aldehyde dehydrogenase was measured in primary cultures of hepatocytes obtained with a two-step collagenase perfusion either from human hepatic tissue or from livers of fisher rats. basal enzyme activity declines gradually as a function of time in culture, but remains at all times higher when measured with propionaldehyde and nad (p/nad) than with benzaldehyde and nadp (b/nadp). treatment of the cultures with 2 microm of 3-methylcholanthrene for four days significantly increased the b-nadp activ ...	1986	3267450

stimulatory effect of interleukin-1 upon hepatic metabolism.	the liver plays an important role in the acute-phase response to sepsis and injury, and host survival often depends upon an adequate hepatic response. many of the metabolic sequelae to sepsis and injury are mediated by interleukin-1. this study was undertaken to investigate the impact of interleukin-1 upon hepatic metabolism and whether this mediator acted directly upon the liver. interleukin-1 (5 rabbit pyrogen dose units) was administered to male fisher f344 rats (175 to 200 g), and hepatocyte ...	1986	3486338
outbreak of candida parapsilosis endophthalmitis after cataract extraction and intraocular lens implantation.	between november 1983 and january 1984, 13 cases of candida parapsilosis endophthalmitis occurred in florida, georgia, and tennessee in patients who had had an intraocular lens implantation (ioli) or cataract extraction with an ioli. this outbreak followed the introduction in july 1983 of a new brand of balanced salt solution (bss) used as an intraoperative ophthalmic irrigation solution. this product was subsequently recalled because of intrinsic fungal contamination. a retrospective cohort stu ...	1986	3490490
nadph binding induced proton ionization as a cause of nonlinear heat capacity changes in glutamate dehydrogenase.	functional group interactions involved in the formation of the glutamate dehydrogenase-nadph binary complex have been studied by three independent but complementary approaches: the ph dependence of the overall dissociation constant measured by an improved differential spectroscopic technique; the ph dependence of the enthalpy of complex formation measured by flow calorimetry; and the ph dependence of the number of protons released to, or taken up from, the solvent in the complex formation reacti ...	1986	3718928
the effect of co2 laser excision on local tumor recurrence.	this study was undertaken to determine the effect of co2 laser surgery on the incidence of local recurrence following tumor recurrence and to study the effect of "sterilization" of the operative site on this phenomenon. sixty fisher 344 rats were implanted with r323oac mammary carcinoma. animals were anesthetized with intraperitoneal pentobarbital, and all tumors were completely excised at 21 days postimplantation. the animals were randomized into groups of 12 as follows: group s underwent excis ...	1986	3724334
alleviation of estrogen-induced hyperprolactinemia through intracerebral transplantation of hypothalamic tissue containing dopaminergic neurons.	prolactin-secreting pituitary tumors can be induced in young rats through prolonged estrogen treatment. recent evidence suggests that such tumors are associated with a degeneration of tuberoinfundibular dopaminergic (ti-da) neurons, which normally inhibit prolactin secretion by the anterior pituitary's lactrophs. for this study, chronic hyperprolactinemia was induced in young, ovariectomized fisher 344 rats through silastic capsule implants of 17 beta-estradiol, placed subcutaneously for 1 month ...	1986	3736784
evaluation of the effects of photoradiation therapy on brain tumors with in vivo p-31 mr spectroscopy.	in vivo phosphorus-31 magnetic resonance (mr) spectra were obtained by a surface coil method from rat glioma tissue inoculated subcutaneously in cd fisher rats, and the effects of photoradiation therapy on tumors were evaluated by sequentially observing spectral changes. in the control group, the nucleoside triphosphate (ntp) and phosphomonoester peaks were large, the phosphocreatine peak was small, and the inorganic phosphate (pi) peak was intermediate. in all eight cases in the group in which ...	1986	3737923
susceptibility of rats to infection with toxocara pteropodis.	infective eggs of toxocara pteropodis were administered to wistar rats via oral and parenteral routes. third-stage larvae were recovered from the livers of suckling young 8 days after oral infection, and from livers and lungs after intraperitoneal or subcutaneous inoculation of eggs. these larvae were short-lived as none were found in suckling mice killed 2 weeks post-infection. larvae were not recovered from tissues of rats aged 22 days or more when inoculated orally, indicating that refractori ...	1986	3751231
a physico-chemical comparison of aortic receptors in rat hypertension models.	rat models of genetic hypertension include spontaneous hypertension and resistance or sensitivity to mineralocorticoid and salt induced hypertension. previously, altered aldosterone binding to corticoid receptor i was found in aortic smooth muscle cells cultured from fischer 344 rats which are extremely resistant to steroid and salt induced hypertension. the corticoid receptor i of fisher 344 rats had a lower affinity than that of salt sensitive wistar-kyoto controls, as well as spontaneously hy ...	1986	3762307
in vitro covalent binding of 14c-mibolerone to rat liver microsomes.	mibolerone (17-hydroxy-7,17-dimethylestr-4-en-3-one; 7 alpha-17 alpha dimethyl-19-nortestosterone) is being marketed by the upjohn company for the inhibition of estrus in bitches. the aim of this study was to determine the extent of covalent binding of mibolerone to rat liver microsomes. liver microsomes were obtained from control and phenobarbitol-treated female fisher rats, and were incubated with 14c-mibolerone at 37 degrees c for 10 minutes. no covalent binding to macromolecules was observed ...	1986	3766302
a comparison of the response of woodchucks and rats to variations in dietary lipotrope and protein content.	juvenile woodchucks and weanling fisher f344 rats were fed purified diets with or without supplemental lipotropic factors (choline, methionine, folic acid and vitamin b-12). the diets contained 10 or 20% protein. lower weight gain due to low protein was observed in both species, while lipotrope depletion resulted in lower gain in male rats only. urinary excretion of formimino-glutamic acid was higher due to low lipotrope in both species, as was relative liver weight. in rats, lipotrope depletion ...	1986	3772530
independence of in vitro iron absorption from mucosal transferrin content in rat jejunal and ileal segments.	isolated non blood-perfused intestinal segments from normal and iron-deficient rats were used in vitro. a modification of the luminal perfusion method according to fisher and parsons allowed the comparison of iron and transferrin quantities in the serosal fluid at 15 min intervals. iron transfer in jejunal and ileal segments was directly proportional to the luminal iron concentration within a dose range of 1 to 100 mumol/l, did not show saturation characteristics and was linear over time. jejuna ...	1986	3779112
2,3-dialkyl(dimethylamino)indoles: interaction with 5ht1, 5ht2, and rat stomach fundal serotonin receptors.	2,3-dialkyl(dimethylamino)indoles, synthesized via the fisher indole synthesis, were found to weakly bind to 5ht1 and 5ht2 sites in brain cortical membranes (ic50 greater than 1 microm at both sites for all compounds). these (dimethylamino)indoles were relatively potent antagonists of the serotonin receptor in the rat stomach fundus. at higher concentrations, several of the compounds were weak agonists at this receptor. for direct comparison with data obtained in the isolated rat fundus, antagon ...	1986	3783602
mechanical responses of developing fisher rat heart. effects of steroid hormone.	age-dependent changes in the mechanical responses of developing fisher rat heart during the first three postnatal weeks were studied in relation to the hypothesis that the abnormality observed in the mechanical responses of the rat heart might be calcium related. therefore the effect of frequency of stimulation as well as the response to calcium, epinephrine and ouabain on hearts of untreated and cortisol-treated rats was compared. the positive force-frequency response observed in fetal rat hear ...	1986	3794225
lipid deposition in the aorta of adjuvant arthritic rats with hypercholesterolemia.	this study offers findings which should aid in the development of a convenient animal model of atherosclerosis. inbred fisher strain rats were fed an atherogenic diet containing 1.5% cholesterol and 0.5% cholic acid and given a single subcutaneous injection of adjuvant (mycobacterium butyricum) into the base of the tail. the animals were maintained for 8 weeks. rats given the atherogenic diet showed markedly increased serum cholesterol levels, and all of those given the adjuvant injection develo ...	1986	3795624
age-related increased susceptibility of male fischer 344 rats to acetaminophen nephrotoxicity.	male fischer 344 rats classified as young (2-4 months), middle-aged (12-14 months) and aged (22-25 months) received 300, 600 or 800 mg/kg acetaminophen (apap) intraperitoneally and were sacrificed 24 hr later. blood urea nitrogen (bun) concentration and urinary glucose and osmolality were determined. in addition, kidneys were evaluated for histopathological changes. apap did not affect osmolality or bun concentrations and failed to produce lesions after any dose in young rats. osmolality was dec ...	1986	3796197
polyomavirus-transformed fr 3t3 rat cells are able to form metastases in syngeneic rats.	a series of polyomavirus-transformed fr 3t3 rat cell lines were tested for their tumorigenic and metastatic properties after subcutaneous inoculation of syngeneic fisher rats. all of them grew into tumors, which appeared with variable latency periods; the td50 varied from cell line to cell line. eight of the 18 transformants that were inoculated gave rise to metastases, always localized in the lung. the capacity to form metastases, though at a low frequency, was also conferred on fr 3t3 cells up ...	1986	3002027
quantitative investigation of the morphological plasticity of synaptic junctions in rat dentate gyrus during aging.	the morphological plasticity of synaptic junctions was investigated by means of quantitative stereology in the dentate gyrus supragranular layer of young (3 months), adult (12 months) and old (30 months) female fisher 344 rats. the numerical (nv) and surface (sv) density and the average surface area (s) of epta-stained synaptic junctions were calculated on 100 em pictures per age group. we found that nv significantly increased between the young and adult group and decreased in old animals when c ...	1986	3697677
renal and hepatic interactions between 2-hexanone and carbon tetrachloride in f-344 rats.	fisher-344 rats were pretreated with 2-hexanone (hx) and challenged with carbon tetrachloride (ccl4) in a replicated 3 x 4 factorial experiment to determine if hx potentiated ccl4-induced renal and hepatic damage. rats given both hx and ccl4 demonstrated more severe hepatic injury at 24 and 48 h than did controls. however, in contrast to our experience with chloroform (chcl3), ccl4-induced renal injury in hx-pretreated rats was only slightly greater than in vehicle-pretreated controls.	1986	3715912
effect of aging on pancreatic lipolytic enzymes.	pancreatic lipolytic enzyme activities and plasma lipids were measured in three age groups of female fisher 344 rats (3 months [young], 12 months [adult], and 27 months [old]) in order to evaluate age-related changes and a possible correlation of these parameters. cholesterol esterase activity was measured in pancreas homogenate, while the lipase activity was further fractionated into heparin-sepharose unretained (lipase i) and retained (lipase ii) fractions. in analogy to the lipolytic enzymes ...	1986	3562438
survival of sylvatic trichinella spiralis isolates in frozen tissue and processed meat products.	the ability of trichinella spiralis larvae to survive at subfreezing temperatures encysted in the musculature of wild carnivorous mammals was assessed by evaluating motility and infectivity (to rodents) of trichinae at various intervals after storage in frozen skeletal muscle. fifty to 60% of the larvae in grizzly bear meat were alive after storage for 27 months at -6.5 to -20 c, and 30% to 50% were still alive at 34 months. however, none survived for 38 months, on the basis of infectivity in mi ...	1986	3505925
in vitro estimation of acoustic parameters of the liver and correlations with histology.	freshly excised human liver specimens (77) were investigated echographically and histologically. the echography was concerned with the acoustic parameters: speed of sound, impedance, several attenuation parameters, and the texture parameters: reflectivity and the signal to noise ratio. it was found that the speed and impedance, the attenuation parameters, and the texture parameters did not correlate with each other. the major correlation between histologic parameters was found for the focal coll ...	1986	3515717
some parameters of conditioned immunosuppression: species difference and cs-us delay.	three experiments were conducted in which an illness-inducing immunosuppressant, cyclophosphamide (an unconditioned stimulus, us) was associated with a previously presented saccharin solution conditioned stimulus (cs). in each experiment, reexposure to the cs produced a conditioned suppression of the plaque-forming-cell response in the experimental groups. experiment i demonstrated this result with fisher 344 rats. experiment ii replicated the effect with balb/c mice. in experiment iii condition ...	1986	3520612
different interactions used by cro repressor in specific and nonspecific dna binding.	the mode of interaction of cro repressor with specific and nonspecific sites on dna was explored by chemical modification and protection of lysine and tyrosine residues. cro has 8 lysines. in the presence of dna, lysines 32 and 56 are fully protected and lysines 21, 62, and 63 are partially protected from alkylation. however, the terminal amino group and lysines 8, 18, and 39 are not protected. location of the protected and unprotected lysines on the three-dimensional cro structure defines a dna ...	1986	3522575
skin graft and kidney transplantation in rats. relation between circulatory condition of the transplanted organ and histocompatibility.	to determine the relationship between histocompatibility and circulation in the transplanted graft, which are the major factors influencing graft survival, the survival of the skin grafts and kidney transplants were compared between strong (aci to lewis) and weak (fisher to lewis) histocompatible strains, because rats given skin graft receive poor blood supply from a recipient, and the rats given kidney transplants receive immediate blood supply after transplant. in the group with a weak histoco ...	1986	3547526
dispersal and other population parameters of aedes aegypti in an african village and their possible significance in epidemiology of vector-borne diseases.	dispersal of aedes aegypti aegypti adults within shauri moyo, an african village in the rabai area north of mombasa, kenya, was studied using the mark-release-recapture method. a total of 920 mosquitoes were captured and uniquely marked, of which 828 (90%) were released and 332 (40%) recaptured. a great majority of mosquitoes were recaptured once, but some individuals were recaptured up to 10 times. most females visited 1 or 2 houses (40.8%, 44.9%, respectively), but there were females that visi ...	1986	3789275
alterations in calmodulin levels in tissues from aged animals.	we measured the levels of calmodulin in brain tissue as well as in other tissues by a specific radioimmunoassay. fisher-344 rats with ages of 3, 13, 23, and 29 months were used. ir-calmodulin levels were reduced in the cortex, striatum, and anterior pituitary but not in the hypothalamus (although there was a tendency for reduction in the latter tissue). no significant decreases in ir-calmodulin were observed in gastrocnemius, kidney, or heart of the oldest group of rats, and, in fact, the levels ...	1986	3941252
acetylcholine, aging and anatomy: differential effects in the hippocampus.	the response to acetylcholine (ach) administered microiontophoretically was determined for single units in ca1 and ca3-4 areas of the hippocampi of both young (3-5 months) and old (24-26 months) fisher 344 rats. single units in ca1 showed a greater response to ach (20 na) than single units in ca3-4 in young and in old rats. however, the response to ach in single units of young rats was significantly greater than in single units of old rats. baseline firing rates in old rats were lower than those ...	1986	3942863
human iga as a heterovalent ligand: switching from the asialoglycoprotein receptor to secretory component during transport across the rat hepatocyte.	asialoglycoproteins are taken up by the rat liver for degradation; rat polymeric iga is taken up via a separate receptor, secretory component (sc), for quantitative delivery to bile. there is negligible uptake of these ligands by the converse receptor, and only a low level of missorting of ligands to opposite destinations. the two pathways are not cross-inhibitable and operate independently (schiff, j.m., m. m. fisher, and b. j. underdown, 1984, j. cell biol., 98:79-89). we report here that when ...	1986	3949883
decremental vasopressin release after repeated stimulation of superfused neurohypophyses of fisher 344 rats of different ages.	we studied the effect of aging on the decline in vasopressin (vp) release from the rat neurohypophyses (nh) as evoked by repeated stimuli with high k+ (56 mm) locke's solution in vitro. isolated nhs, without pars intermedia, of 2-, 12- and 30-month-old male fisher 344 rats arbitrarily labeled as young, adult, and old were individually superfused with synthetic medium tc 199. following the initial traumatic release, the glands were stimulated three times for 10 min each with recovery periods of 3 ...	1986	3950338
reduction of motor behavioral deficits in senescent animals via chronic prolactin administration. ii. non-stereotypic behaviors.	the effects of chronic prolactin administration on three non-stereotypic psychomotor behaviors (inclined screen performance, rod walking and wire hanging) were examined in senescent (24 month) fisher 344 rats. prolactin (150 ng/hr) was administered for 7 days via alzet minipumps to rats which had been pretested on the three tasks. the animals were tested on days 4 and 7 following the implants and the pumps were removed after testing on day 7. in order to assess the persistence of any prolactin e ...	1986	3951657
