first person account: finding myself and loving it.	the article that follows is part of the schizophrenia bulletin's ongoing first person accounts series. we hope that mental health professionals--the bulletin's primary audience--will take this opportunity to learn about the issues and difficulties confronted by consumers of mental health care. in addition, we hope that these accounts will give patients and families a better sense of not being alone in confronting the problems that can be anticipated by persons with serious emotional difficulties ...	1984	6701475
duaal processes in recognition and in recognition failure.	it is argued that adherence of the results of experiments in the recognition failure paradigm to the function observed by tulving and wiseman (1975) reflects the operation of two distinct processes in recognition similar to those described by mandler (1979, 1980). familiarity decisions based on the target word alone can occur when target and list cue have not been integrated and result in some measure of dependence between recall and recognition. contextual retrieval can operate in recognition w ...	1984	21287047
miller fisher syndrome: clinical and electrophysiologic evidence of peripheral origin in 10 cases.	clinical and electrophysiologic data recorded in patients with fisher syndrome characterized by ophthalmoplegia, ataxia, and areflexia are presented. cases with limb weakness or pleocytosis in the csf were excluded, according to fisher. ten patients were selected. all had hand and foot numbness. a large amount of protein without cell reaction was found during the third week of illness in serial csf examinations. emgs showed very slight limb involvement without spontaneous activity, and in most c ...	1984	6539872
effects of n,n'-dicyclohexylcarbodiimide and n-(ethoxycarbonyl)-2-ethoxy-1,2-dihydroquinoline on hydride ion transfer and proton translocation activities of mitochondrial nicotinamidenucleotide transhydrogenase.	n,n'-dicyclohexylcarbodiimide (dccd) inhibits the mitochondrial energy-linked nicotinamidenucleotide transhydrogenase (th). our studies [phelps, d.c., & hatefi, y. (1981) j. biol. chem. 256, 8217-8221; phelps, d.c., & hatefi, y. (1984) biochemistry 23, 4475-4480] suggested that the inhibition site of dccd is near the nad(h) binding site, because nad(h) and competitive inhibitors protected th against inhibition by dccd and, unlike the unmodified th, the dccd-modified th did not bind to nad-agaros ...	1984	6099137

the pacing stress test: a reexamination of the relation between coronary artery disease and pacing-induced electrocardiographic changes.	electrocardiographic (ecg) changes during graded pacing-induced tachycardia have been considered unreliable as a test for the presence of coronary artery disease (cad) because of poor sensitivity and specificity. as a result, atrial pacing has not been widely used as an alternative to exercise testing. however, the limited value of the pacing stress test may be related to technical aspects, such as the duration of pacing and ecg monitoring. to study this problem, 22 patients undergoing coronary ...	1984	6741838
the effects of prolactin on rat testicular steroidogenic enzyme activities.	to investigate whether hyperprolactinemia directly affects rat testicular steroidogenesis, we examined the effects of prolactin (prl) on microsomal 3 beta-hydroxysteroid dehydrogenase (3 beta-hsd) 17-hydroxylase (17-oh), 17,20-desmolase (17,20-d), 17-ketosteroid reductase (17-ksr) and aromatase enzyme activities. adult hypophysectomized, gonadotropin-treated fisher rats were rendered hyperprolactinemic by isografting pituitaries under the kidney capsule. the controls received skeletal muscle. al ...	1985	3967847
the efficacy of total parenteral nutrition in malnourished tumor-bearing rats.	the current study was designed to compare the efficacy of total parenteral nutrition (tpn), provided either before or after tumor removal, in replenishing protein stores in the malnourished tumor-bearing (tb) host. fisher 344 rats bearing a transplantable methylcholanthrene (mca)-induced sarcoma were used. after the animals were cachectic from their tumor, a central venous catheter was inserted. at the time of catheter insertion, the animals were randomized into two groups. group i rats had the ...	1985	3918782
strain differences and laminar localization of structural neurochemical changes in aging rat.	to obtain comparisons of age-related microchemical changes in cerebral cortex of two commonly employed rat strains (fischer 344 and sprague-dawley), neurochemical assays of substances regarded as quantitative indices of structural entities in brain were performed. these included dna as a marker for cells, lipid sialoganglioside as an index of neuronal membrane mass, and galactocerebroside as an index of myelin. fischer 344 rats were studied at 3-4 months (young), 14-16 months (middle age) and 25 ...	1985	4088423
[cerebral lymphoma associated with lesions of multiple sclerosis].	a 24 year-old man experienced a left retrobulbar neuritis which improved completely after 2 months of non-steroid antiinflammatory therapy. one month after the end of the treatment he developed a korsakoff-like amnestic syndrome. three months later he complained of horizontal diplopia. a ct scan showed a diffuse enhancement of the periventricular areas, corpus callosum and fornix. diplopia and ct scan abnormalities disappeared after the administration of tetracosactide. subsequently a progressiv ...	1985	4089407
modification of experimental gentamicin nephrotoxicity by selective parathyroidectomy.	dietary calcium loading reduces gentamicin nephrotoxicity in rats. since parathyroid hormone increases renal brush border membrane anionic phospholipids, the putative gentamicin receptors, the effects of selective parathyroidectomy on gentamicin nephrotoxicity were examined. male fisher 344 rats underwent parathyroidectomy or sham surgery. all animals were fed a diet containing 0.5% calcium for 2 wk prior to gentamicin, 20 mg/kg twice daily for 6 and 10 days. other parathyroidectomized rats were ...	1985	4073266
an all-glass perfusator for investigation of the intestinal transport and metabolism of foreign compounds in vitro.	the in vitro perfusion technique of surviving intestinal segments as described by fisher and parsons (1949) and modified by rummel and stupp (1960) was further improved by the introduction of an all-glass perfusator for studying the intestinal transport and metabolism of lipophilic xenobiotics.	1985	4079445
image analysis of gfa-positive astrocytes from adolescence to senescence.	smears of fresh rat brain tissue combined with immunohistochemistry using antiserum to glial fibrillary acidic protein (gfa) were used to visualize individual astrocytes in different cortical regions of rats ranging in age from 1 to 30 months. by computerized image analysis, the cell area and the cell perimeter were determined. using 4-month-old male sprague-dawley rats, it was found that gfa-positive astrocytes from cerebellum and hippocampus were significantly larger, both in terms of cell are ...	1985	3987847
effects of chronic bromocriptine treatment of an estrone-induced, prolactin-secreting rat pituitary adenoma.	bromocriptine (brom), a dopamine (da) agonist, is commonly and successfully used for long-term treatment of human prolactinomas. we have studied the effects of chronic brom administration to female 344 fisher/lis rats bearing an estrone-induced, prolactin (prl)-secreting pituitary tumor recently characterized as a model for human prolactinoma. the animals were injected twice daily with brom (2.5 mg/kg) or with diluent. after 1 month of treatment, the animals were sacrificed, and plasma collected ...	1985	3997065
a macrophage-mediated factor that increases the high energy phosphate content of skeletal muscle.	a marked cellular infiltrate accompanies wounding. the phagocytic and bacteriocidal activities of this infiltrate require increased substrate and o2 consumption. this rapid utilization of available oxygen and substrates could jeopardize an already compromised resident cellular component of a wound. recent studies have demonstrated macrophage-mediated cell stimulatory agents which induce proliferation of nonlymphoid mesenchymal cells. this study was designed to examine macrophage-resident tissue ...	1985	3999732
growth-depressing effects of alcohol and nicotine in two strains of rats.	inbred buffalo and fisher rats were submitted to daily treatment with alcohol and nicotine for a period of 6 months. alcohol treatment was pre- and postnatal, nicotine treatment postnatal only. all parameters of bone length and weight were depressed in both experiments in spite of the continuous growth of the rats. although the level of depression was greater in some areas than in others, a clear target area applicable to both sexes and strains could not be found. fisher and buffalo females tole ...	1985	4003023
macrophage interaction with skeletal muscle: a potential role of macrophages in determining the energy state of healing wounds.	a decrease in atp and creatine phosphate (cp) is characteristic of local injury to skeletal muscle. recent data have suggested adequate potential for high-energy phosphate production in the wounded tissue. thus, an adequate explanation for the deficit in the high-energy tissue content in wounds was lacking. since the wound has multiple components (muscle + cellular infiltrate), the tissue content represents the summation of these components. therefore, a technique to separate these components wa ...	1985	4020909
correlation of human bladder tumor recurrence with changes in clonogenicity of urothelial cells.	over a 2-year period 340 cystoscopies were performed on 174 patients (126 men and 48 women) followed up for previously treated transitional cell tumor of the bladder or new cases suspected of having bladder tumor. bladder washings taken at cystoscopy in 66% yielded cells for clonogenic assay. patients with transitional cell tumors had an average clonogenic index (ci) of 14 (+/- 5) colonies per 10(5) viable urothelial cells, whereas previously tumorous patients with tumor-free bladders had an ave ...	1985	4027894
in vivo and in vitro antiestrogenic action of 3-hydroxytamoxifen, tamoxifen and 4-hydroxytamoxifen.	this study demonstrates in vivo and in vitro properties of the non-steroidal antiestrogens tamoxifen (tam), 4-oh-tamoxifen (4-oh-tam) and 3-oh-tamoxifen (k 060 e). in immature rabbit uteri 4-oh-tam and k 060 e bound to the respective estrogen receptors with a ten-fold higher affinity than tam. furthermore, k 060 e exhibited less agonistic (estrogenic) but higher antagonistic (antiestrogenic) activity in the immature rat uterus than tam and 4-oh-tam (change of uterine weight). the ratio of agonis ...	1985	4043181
long-term consequences of cis-platinum-induced renal injury: a structural and functional study.	previous studies have shown that a single dose of the antitumor drug, cis-platinum, causes renal cyst formation in rats 1-6 months after drug injection. this observation led to a further evaluation of the long-term effects of cis-platinum on the kidney of the rat. fisher 344 rats (n = 13) were given either a single intraperitoneal injection of cis-platinum (6 mg/kg body weight) or saline (control) and 15 months later renal function and pathology were assessed. the glomerular filtration rate and ...	1985	4061878
post-partum antibody-dependent cell-mediated immunity in the rat following perinatal exposure to iodine-131.	a study was recently completed which indicated the first generation of adult rats that had been exposed perinatally to iodine-131 possessed peripheral blood lymphoid-cells capable of expressing cytotoxicity towards cultured small bowel adenocarcinoma target cells, i.e., active antitumor cell-mediated immunity (cmi). the results gathered during the current investigation suggest that such animals similarly express anti-tumor antibody-dependent cell-mediated immunity (adcc). the animal model employ ...	1985	4062256
arousal deficit shown in aged rat's quantitative eeg and ameliorative action of pramiracetam compared to piracetam.	the basal eeg profile of the aged fisher-344 rat was consistently different from that of the young rat, showing dominant high voltage slow-wave components. these slow waves were present in both the frontal cerebral cortex and dorsal hippocampus. absent or greatly attenuated in the aged rat's hippocampal eeg was rhythmic theta activity, which was always dominant in the young awake rat's hippocampus. these eeg differences were clearly apparent only under basal test conditions, i.e., following habi ...	1985	4065299
a walker 256 tumor-induced osteogenic small animal model for the evaluation of [99mtc] diphosphonate radiopharmaceuticals.	a mammalian model has been developed for the in vivo evaluation of bone imaging agents. the model is based upon the quantification of a discrete, initial secondary periosteal osteogenesis induced in cortical bone immediately adjacent to an intramuscularly implanted walker 256 tumor in fisher 344 rats. evaluation of the model consists of a histopathological examination of the periosteal bone formation, biodistribution studies on 99mtc-mdp and 99mtc-hmdp commercial kit preparations, and biodistrib ...	1985	4066198
measles outbreak in a pediatric practice: airborne transmission in an office setting.	in february 1981, a measles outbreak occurred in a pediatric practice in dekalb county, ga. the source case, a 12-year-old boy vaccinated against measles at 11 1/2 months of age, was in the office for one hour on the second day of rash, primarily in a single examining room. on examination, he was noted to be coughing vigorously. seven secondary cases of measles occurred due to exposure in the office. four children had transient contact with the source patient as he entered or exited through the ...	1985	3982900
effects of factors derived from a tumor clonal cell line on dna synthesis of transformed and non transformed cells.	conditioned medium from neoplastic thyroid cell cultures, extracts of tumors developed by identical cells in isogeneic fisher 344 rats and serum from those tumor-bearing animals, were tested in pulse thymidine labelled experiments on a transformed and two non transformed cell lines. tumor extract and conditioned medium inhibited dna synthesis. tumor-bearing rat serum increased dna synthesis in a cerebellar transformed cell line, but no in chick embryo fibroblasts or in aorta non transformed cell ...	1985	3986917
inhibitory effects of secretin on gastrin-stimulated rat colon neoplasms.	a study was done to determine if continuous administration of exogenous secretin would inhibit the trophic effect of elevated endogenous gastrin on colon neoplasms in rats. colon tumors were induced in 37 fisher rats by subcutaneous injection of 1,2-symdimethylhydrazine, 20 mg/kg, weekly for 18 weeks. elevation of endogenous gastrin was achieved by antral exclusion surgery. control rats received a sham operation. subcutaneous osmotic minipumps delivered 35.5 u/kg/day of secretin for 7 days befor ...	1985	3971292
effects of phenobarbital and skf-525a on in vitro hepatic metabolism of verapamil and nifedipine.	both verapamil and nifedipine are first-generation calcium-entry antagonist drugs which are eliminated by hepatic metabolism. to evaluate the effects of enzyme induction and suppression on the biotransformation of these compounds, liver homogenate fractions were prepared from male fisher (f344) rats, which were either untreated, or injected intraperitoneally with phenobarbital or with skf-525a prior to sacrifice. known concentrations of verapamil or nifedipine were incubated with the 9,000 g sup ...	1985	3975261
comparison of the energetics of the uncatalyzed and glutamate dehydrogenase catalyzed alpha-imino acid-alpha-amino acid interconversion.	the thermodynamic and activation parameters for the reduction of delta 1-pyrroline-2-carboxylic acid (an alpha-imino acid) by reduced nicotinamide adenine dinucleotide phosphate (nadph) are compared with those for the reduction of the same imino acid by the glutamate dehydrogenase-nadph complex. the enthalpies of activation and standard free energy changes for these two reactions are found to be virtually the same. the catalysis by the enzyme, expressed as the ratio of the reactivity of the enzy ...	1985	4074700
effect of surgery on tumor-induced accelerated coagulation in a rat carcinoma.	accelerated coagulation detected by thromboelastography has been reported in early stages of tumor growth. the present investigation was conducted to determine the changes in tumor-induced accelerated coagulation following complete and partial resection of the tumor. male fisher rats were divided into four groups: (1) control, (2) tumor-bearing rats, (3) complete resection, (4) partial resection. in groups 2, 3, and 4 a 2-mm3 piece of squamous cell carcinoma (nci 11095) was implanted subcutaneou ...	1985	3968872
tyrosine motions in relation to the ferric spin equilibrium of cytochrome p-450cam.	second derivative spectroscopy was used to determine the percentage of tyrosine residues that are exposed to solvent in cytochrome p-450cam isolated from pseudomonas putida. the ratio between two peak to trough second derivative absorbance differences has been shown to be dependent on the polarity of the microenvironment surrounding tyrosine residues [ragone, r., colonana, g., balestrieri, c., servillo, l., & irace, g. (1984) biochemistry 23, 1871]. with a number of camphor analogues that indepe ...	1985	4084552
effect of age on fever and acute-phase response of rats to endotoxin and salmonella typhimurium.	age-related effects on endogenous pyrogen-mediated febrile and acute-phase responses to endotoxin and salmonella typhimurium challenge were investigated in young adult and aged fisher 344 rats. after injection of endotoxin, the febrile response over 6 h and the fall in plasma iron and zinc after 6 h were determined in 14 young adult and 14 aged rats in their thermoneutral zone (26 degrees c) and in 14 young adult and 14 aged rats maintained in a cold environment (15 degrees c). although at 26 de ...	1985	3880718
approaches to prostatic cancer chemotherapy using the dunning r3327h prostatic adenocarcinoma.	androgen-responsive cells: to determine if testosterone or dihydrotestosterone is the main trophic hormone of prostatic adenocarcinoma, we have treated dunning r3327h prostatic adenocarcinoma-bearing rats with 6-methylene progesterone, which blocks conversion of testosterone to dihydrotestosterone. copenhagen-fisher rats were treated with steroid (20 mg/kg daily) immediately following implantation of tumor and thereafter for 117 days. there was a 92% inhibition of growth of tumors and a lesser e ...	1985	3975175

time course of induction of prolactin-secreting pituitary tumors with diethylstilbestrol in male rats: response of tuberoinfundibular dopaminergic neurons.	3,4-dihydroxyphenylalanine (dopa) accumulation and dopamine (da) and noradrenaline levels were measured in the median eminence (me) of fisher 344-derived inbred male rats. these animals had been treated with silastic capsules containing 8-9 mg diethylstilbestrol (des) or with empty capsules for 3, 7, 14, or 30 days and had the pellets removed 22 days before killing. in an additional group of rats, the des pellets were continuously present until killing. blood was collected before treatment was s ...	1985	3917247
monoclonal antibodies prepared against the major drosophila nuclear matrix-pore complex-lamina glycoprotein bind specifically to the nuclear envelope in situ.	a high molecular weight glycoprotein found associated with a nuclear matrix-pore complex-lamina (nmpcl) preparation obtained from drosophila melanogaster embryos has been shown by in vitro analyses to be largely confined to this subcellular fraction. in contrast with several of the nmpcl proteins, this glycoprotein remains completely insoluble after treatment with 5 m urea. it has, therefore, been possible to separate the glycoprotein from other nmpcl components by differential urea extraction. ...	1985	3919018
presence of high affinity dopamine receptors in estrone-induced, prolactin-secreting rat pituitary adenomas: a model for human prolactinomas.	adenomatous cells obtained from a pituitary tumor induced in fisher 344/lis rats by the subcutaneous implantation of estrone (e1) were found to secrete large amounts of prolactin (prl). the secretion of prl was stimulated by thyrotropin-releasing hormone (trh) and low concentrations of dopamine (da), while micromolar concentrations of da were inhibitory. high affinity binding sites for 3h-spiroperidol (3h-spir) were found to be present on the cells and to conform to the criteria of dopaminergic ...	1985	3920132
polylactosamine glycosylation on human fetal placental fibronectin weakens the binding affinity of fibronectin to gelatin.	gelatin-binding chymotryptic fragments from placental fibronectin contain polylactosamine carbohydrates (zhu, b.c.r., fisher, s.r., pande, h., calaycay, j. shively, j.e., and laine, r.a. (1984) j. biol. chem. 259, 3962-3970). we have separated polylactosamine-containing gelatin-binding fragments of placental fibronectin from their counterparts containing smaller "complex" n-linked saccharides using sephadex g-200 gel permeation chromatography. the peptide portions of both fragments have similar ...	1985	3920213
delayed enzyme expression: a defect of aging rat gut.	to evaluate the effect of aging upon the small intestine, the distribution, content, and concentration of epithelial cell enzymes at different levels along the crypt-villus column were measured in aging and young adult, male, fisher 344 rats. specific activities of sucrase, maltase, lactase, and adenosine deaminase in mucosal homogenates were lower in the upper intestines of aging than in young animals, whereas the specific activity and content of thymidine kinase was higher. enzyme activities w ...	1985	3930340
the effect of parenteral nutrition on gastrointestinal immunity. the importance of enteral stimulation.	secretory iga (s-iga), an immunoglobulin present in secretions, prevents the adherence of bacteria to mucosal cells and is the principle component of the gut mucosal defense system. the purpose of this study was to determine whether the route of nutrient administration affects s-iga. twenty-five female fisher rats were randomized into three groups. groups i and ii were fed an isonitrogenous, isocaloric standard hyperalimentation solution, group i intravenously and group ii via a gastrostomy. gro ...	1985	3935061
residuals in multiple regression analysis.	an examination of residuals can be used as a technique to determine the best model for use in multiple-regression analysis. in addition to r2 and the fisher f ratio, a complete analysis of residuals has been used by statisticians for many years to estimate bias and to choose the best equation to fit physicochemical as well as biological and psychosociological data. however, residual analysis has seldom appeared in studies in pharmaceutics, pharmacology, or medicinal chemistry. this report gives ...	1985	3935772
maternal epilepsy and birth defects: a case-control study in the italian multicentric registry of birth defects (ipimc).	a case control study on the association between maternal epilepsy, anticonvulsants use during pregnancy and birth defects was carried out in the italian multicentric registry of birth defects (ipimc). in the period 1980-1983, 7,607 malformed babies out of 439,717 total births (still + live) were registered. fourty-one malformed babies with maternal epilepsy were identified (5.39 x 1,000). the overall relative risk of having a malformed baby among pregnant epileptic women was 1.87. spina bifida, ...	1985	3939491
hepatocarcinogenic and promoting action of a choline-devoid diet in the rat.	male fisher 344 rats were solely fed a choline-supplemented diet for 65 to 105 weeks or a choline-devoid diet for 24 to 102 weeks. hepatocellular carcinomas developed in the latter animals, beginning at 24 weeks. other groups of rats were given a single dose of 20 mg diethylnitrosamine/kg, 18 h after a partial hepatectomy and were fed, 4 weeks thereafter, either a choline-supplemented, or a choline-devoid diet for up to 48 weeks. in rats fed the choline-supplemented diet, the only relevant lesio ...	1985	2859112
fiber number and type composition in extensor digitorum longus, soleus, and diaphragm muscles with aging in fisher 344 rats.	histochemical (m-atpase) fiber typing was done on extensor digitorum longus, (edl), soleus (sol), and diaphragm (dia) muscles of barrier-reared fisher 344 rats obtained at four different ages (3, 9, 28, and 30 months) from the colonies of the national institute of aging. in the edl there are no differences in the percent of type i fibers among the four age groups. the percent of type iia and iib fibers also showed no difference between the 3 and 30 month age groups. there was no apparent trend f ...	1985	2931475
dopaminergic modulation of the diethylstilbestrol-induced proliferation of the anterior pituitary gland of the fisher 344 rat.	bromocriptine (cb 154), a potent agonist upon the d-2 receptor, blocks the proliferation of the mammotrophs and the elevation of serum prolactin concentration induced by chronic exposure of male fisher 344 rats to diethylstilbestrol (des). fluphenazine, a dopamine receptor antagonist, blocks these effects of cb 154. we conclude that a d-2 receptor occurs on the proliferating mammotroph of the male fisher 344 rat and that stimulation of this receptor inhibits prolactin release and stops the des-i ...	1985	2932654
morphine dependence and protracted abstinence: regional alterations in cns radioligand binding.	rats (fisher f-344) were given free access to a 10% sucrose solution containing 0.5 mg/ml morphine sulfate (controls received the sucrose vehicle only) as their sole source of fluid. daily morphine intake averaged 119 +/- 21 mg/kg, an amount sufficient to induce physical dependence. after 18 days on this regimen, the control and dependent subjects were sacrificed. a protracted abstinence group was weaned from morphine by reducing its concentration in the vehicle by 20% over the next 5 days, foll ...	1985	3001786
somatic antigens of pseudomonas aeruginosa. the structure of the o-specific polysaccharide chains of lipopolysaccharides of p. aeruginosa serogroup o4 (lányi) and related serotype o6 (habs) and immunotype 1 (fisher).	acidic o-specific polysaccharides were isolated on mild acidic degradation of lipopolysaccharides of pseudomonas aeruginosa serotypes o4a,b, o4a,c, o4a,d (lányi classification) and serologically related to them serotype o6 (habs classification) and immunotype 1 (fisher classification). the polysaccharides had identical monosaccharide composition and were built up of l-rhamnose, 2-acetamido-2,6-dideoxy-d-glucose,2-formamido-2-deoxy-d-galacturonic acid and 2-acetamido-2-deoxy-d-galactouronamide re ...	1985	2410275
effects of interferon on differentiation of normal and tumor cells.	as described in this review, both partially purified and recombinant interferons are potent modulators of differentiation in diverse cell culture systems (table 2). depending on the target cell, interferon exerts either an inhibitory or an inductive effect on cell differentiation. in certain myeloid leukemic cells, such as hl-60, interferon by itself is growth suppressive but does not induce cell maturation, whereas in combination with inducers of differentiation, such as dmso, tpa or retinoic a ...	1985	2412243
rat lung macrophage tumor cytotoxin production: impairment by chronic in vivo cigarette smoke exposure.	macrophages in the presence of bacteria-derived lipopolysaccharide (lps) stimuli produce a soluble cytotoxin which is toxic to tumor cells. in this study, we examined various parameters of cytotoxin production from pulmonary lavage cells obtained from fisher 344 cesarean-derived rats. cultures of macrophages were derived from pulmonary lavage cells and stimulated in vitro with lps. cytotoxin production was assayed in vitro using an l-929 cell target assay. pulmonary lavage preparations contained ...	1985	2413988
characteristics of normal rat mammary epithelial cells and n-ethyl-n-nitrosourea-induced mammary adenocarcinoma cells grown in culture.	the characteristics of normal mammary epithelial cells derived from lewis and sprague-dawley rats and n-ethyl-n-nitrosourea (enu)-induced mammary gland adenocarcinoma cells derived from sprague-dawley (cd) and fisher (cdf) rats and grown in culture were compared. after collagenase treatment, the rat mammary epithelial cell aggregates were placed in a hormone-supplemented medium. the normal mammary epithelial cells (ne) attached to the surface of the dish within 50 hours, whereas the mammary aden ...	1985	2415045
pausing of rna polymerase during in vitro transcription through the ilvb and ilvgeda attenuator regions of escherichia coli k12.	synchronized single-round transcriptions, in vitro, from templates encoding the leader rna of the ilvb and ilvgeda operons result in the accumulation of a transcript consistent with rna polymerase pausing after the 1:2 stem that could form in each of the leader rnas. addition of l-factor or guanosine 5'-diphosphate,3-diphosphate extended the pause half-life obtained with the ilvb template; addition of l-factor and guanosine 5'-diphosphate,3'-diphosphate together had an additive effect on the pau ...	1985	2578464
short- and long-term evaluation of normal and abnormal human thyroid cells in monolayer culture.	we have investigated the tsh responsiveness of normal and abnormal human thyroid cells cultured in the short term with high serum concentrations and for up to 6 months in a low serum, chemically-defined, medium. cells from normal human thyroid tissue (n = 9), multinodular goitre (n = 6), benign follicular adenomata (n = 6), and differentiated thyroid carcinoma (n = 3) formed confluent monolayers which were sensitive to bovine tsh (btsh) in concentrations greater than 25 microu/ml when assessed b ...	1985	3002667
testicular lh receptors during aging in fisher 344 rats.	levels of serum lh, prolactin, testosterone, progesterone and 17-oh progesterone and the testicular concentration and total content of lh receptors were measured in 4-, 11-, 18-, and 27-month-old fisher 344 rats. all 27-month-old rats had leydig cell tumors. at first, testicular lh receptor levels decreased with age, but with the appearance of the testicular tumors, these levels increased dramatically. serum prolactin levels fluctuated with age, but were significantly decreased in 27-month-old r ...	1985	2982778
stability and utility of the unique human small cell carcinoma line shp-77.	the human small cell (oat cell) carcinoma line, shp-77, established by fisher and paulson in 1977 and originally described as a "large cell variant of oat cell cancer" has been evaluated by several different parameters and shown even after more than 200 passages to retain properties described for the original cell line. karyotypic, histological, and biochemical features are retained, as well as tumorigenicity in nude mice. the original authors' suggestion that this is a propitious cell line for ...	1985	2985251
the simian virus 40 sequences between 0.169 and 0.423 map units are not essential to immortalize early-passage rat embryo cells.	f8dl is a simian virus 40 early-region deletion mutant that lacks the sequences between 0.169 and 0.423 map units. we show that cloned f8dl dna immortalized early-passage fisher rat embryo cells with an efficiency that was about 20% of that of cloned wild-type simian virus 40 dna. in contrast, we detected no immortalized colonies when we transfected the cells with dna of five other early-region deletion mutants that do not make stable truncated forms of t antigen. since all five of these mutants ...	1985	2987680
2,4-dichlorophenoxyacetic acid (2,4-d) does not cause polyneuropathy in the rat.	2,4-dichlorophenoxyacetic acid (2,4-d), a component of agent orange, was injected intraperitoneally into adult male fisher rats for 3-12 weeks. during the period of study gait and toe-spreading reflexes remained normal and distal motor latencies, motor and mixed nerve conduction velocities and amplitudes remained similar (p greater than 0.05) in animals receiving 2,4-d or vehicle. this study suggests that 2,4-d is not toxic to peripheral nerves in the rat.	1985	2997403
selective inhibition of leukotriene b4 biosynthesis in rat pulmonary alveolar macrophages by dietary selenium deficiency.	weanling male fisher 344 rats were maintained on low selenium basal and se-supplemented diets for 38 weeks. a several fold reduction in the glutathione peroxidase activity of the lung and liver tissues in rats maintained on low se basal diet established their se-deficient status. analysis of the supernatants from resting pulmonary alveolar macrophage suspensions showed negligible extracellular release of pge2, txb2 and ltb4 in both diet groups. a challenge with opsonized zymosan particles increa ...	1985	2998361
hepatic neoplastic nodules, adenofibrosis, and cholangiocarcinomas in male fisher 344 rats fed corn naturally contaminated with fusarium moniliforme.	twelve male fisher 344 rats were fed corn naturally contaminated with fusarium moniliforme. this corn sample was obtained from feed being fed horses during an outbreak of leukoencephalomalacia. all rats necropsied from 123 to 176 days post feeding had multiple hepatic nodules and pale depressed hepatic areas. histological examination revealed multiple hepatic neoplastic nodules and large areas of adenofibrosis and cholangiocarcinomas. the corn only diet was deficient in many nutrients including ...	1985	2990756
lambda phage cro repressor interaction with its operator dna: 2'-deoxy-5-fluorouracil or3 analogues.	the experiments here show that chemically synthesized dna containing fluorine at selected sites can be used to test specific predictions of a model for cro repressor--operator interaction. this is done by observation of the perturbation to the fluorine-19 nmr spectra of analogues of or3 synthesized with 2'-deoxy-5-fluorouracil at specific positions in the dna helix. although the three-dimensional structure of the cro repressor from phage lambda has been determined by matthews and co-workers [and ...	1985	3157402
the autologous mixed lymphocyte reaction is decreased in freund's adjuvant-injected rats of arthritis-susceptible and -insusceptible strains.	we examined the t-non-t cell autologous mixed lymphocyte reaction (amlr) of spleen cells from rats with arthritis induced by freund's complete adjuvant in an effort to establish an animal model for the study of the relationship between the amlr and autoimmune disease. we found that the splenic t-non-t amlr was markedly decreased in rats with adjuvant-induced arthritis and that this decrease was mediated by suppressor cells within the nylon-wool-adherent stimulator cell population. however, we al ...	1985	3159391
penetrating corneal transplantation in the inbred rat: a new model.	a model of orthotopic penetrating keratoplasty has been developed in the inbred rat using both avascular and prevascularized recipient beds. the surgical procedure is conventional and can be achieved with standard instrumentation. isografts into avascular recipient beds (fisher 344 into fisher 344 strain combination) were successful and survived indefinitely with excellent corneal function judged either visually by clarity and lack of oedema, or histologically at autopsy. allografts into avascul ...	1985	3881365
ntp toxicology and carcinogenesis studies of diallylphthalate (cas no. 131-17-9) in f344/n rats (gavage studies).	diallylphthalate is widely used as a crosslinking agent for unsaturated polyesters. diallylphthalate or diallylphthalate polyester blends are used primarily as plasticizers and carriers for adding catalysts and pigments to polyesters and in molding, electrical parts, laminating compounds, and impregnation of metal castings. rubber compounds, epoxy formulations, and polyurethane foams may also contain diallylphthalate. precise figures are not currently available, although annual production of dia ...	1985	12748696

the evolution of dominance: haldane v fisher revisited.	fisher's model for the evolution of dominance indicates that the accumulation of dominance modifiers will be accelerated by (1) an increased frequency of the mutant heterozygote, (2) increased selection for the phenotype of the normal homozygote. the model has been criticised by haldane on the grounds that point (1) is not fulfilled, that is dominance appears to be more common in populations with a low frequency of mutant heterozygotes (populations of inbreeders). in support of fisher's model it ...	1985	268310

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
the haemorheological features of lacunar strokes.	clinical and haemorheological data were recorded in 40 patients with lacunar strokes confirmed clinically and by computed tomography. the following haemorheological variables were monitored: haematocrit, erythrocyte aggregation, erythrocyte deformability, plasma viscosity, fibrinogen concentration and yield shear stress. clinically, most patients had case histories and features according to the description of fisher. all haemorheological parameters with the exception of the haematocrit were path ...	1985	4078601
prediction of developmental attainments of institutionalized mentally retarded children.	two regression equations using chronological age and either iq or the fisher and zeaman k score were developed to predict developmental record ratings of institutionalized mentally retarded children over a 2-year interval (n = 200), a 4-year interval (n = 165), and an 8-year interval (n = 95). although the correlations between predicted and obtained scores for both equations were quite high even over an 8-year interval, analysis of mean differences revealed that the equation using iq yielded mor ...	1985	3976735
