aerosol stability and respiratory infectivity of japanese b encephalitis virus.experiments were conducted to examine the aerosol stability and respiratory infectivity of japanese b encephalitis virus. at 75 degrees f (about 24 degrees c), survival of the virus as aerosol was inversely related to relative humidity. after correction for physical decay, the mean virus half-lives of the virus were 28, 38, and 62 min at relative humiditis of 80, 55, and 30%, respectively. virus recoveries as aerosol at 4 min aftr dissemination generally exceeded the theoretical limit of 100%, b ...19806254888
effect of magnesium deficiency on erythrocyte aging in rats.rats placed on a magnesium-deficient diet show decreased erythrocyte magnesium concentration, shortened erythrocyte survival, and erythrocyte membrane ultrastructure defects and become progressively anemic. whether these pathologic processes are due to abnormal erythropoiesis or occur in the peripheral circulation is unknown. in the present study, magnesium and hemoglobin concentrations, reticulocyte count, erythrocyte pyrophosphatase, and pyruvate kinase activities were determined at weekly int ...19806106388
age-related changes in dopamine, lhrh and somatostatin in the rat hypothalamus.the distribution of dopamine, somatostatin and lhrh was examined in young and aged male rats of the fisher 344 strain. dopamine histofluorescence and peptide immunocytochemical staining were performed together in each animal by the use of a stimultaneous visualization technique. comparative analysis or rats at 3, 12, 20, and 30 months of age revealed a general decrease in somatostatin and lhrh in the median eminence; dopamine fluorescence intensity also was depressed in the median eminence altho ...19806115324
distinct transformation phenotypes induced by polyoma virus and simian virus 40 in rat fibroblasts and their control by an early viral gene function.several transformed cell lines established from fisher rat cells (fr 3t3) infected with wild-type polyoma virus or simian virus 40 or early temperature-sensitive mutants (polyoma tsa and simian virus 40 tsa30) were studied for their transformation phenotypes. the distinct patterns which were obtained for polyoma and simian virus 40 transformants led to the conclusion that these two viruses express different transforming abilities in rat cells. the results obtained with temperature-sensitive muta ...19806251242
control of growth of estrogen-sensitive cells: role for alpha-fetoprotein.the role played by alpha-fetoprotein (afp) during the perinatal period in rats has not yet been ascertained despite earlier suggestions that this plasma protein affected the multiplication, in an "in animal-in culture" system of tumor cells that are stimulated by estrogen (e) for growth. to test this inference developed from our previous work, afp was purified by reverse affinity chromatography to homogeneity by electrophoretic and immunochemical criteria. purified afp was added at different con ...19806154944
cyclic nucleotides and platelet aggregation in hypertensive rats with ectopic pituitary tumor.the transplantable pituitary tumor mtt-f4 secretes several pituitary hormones in fisher rats, resulting in severe cardiovascular disease with a mineralocorticoid type of hypertension and hyperlipidemia. the mineralocorticoid-dependent hypertension possesses particular characteristics in humans and animals. it was of interest to study cyclic nucleotides and platelet aggregation in the fisher rat with an mtt-f4 tumor in order to evaluate the type of abnormalities in this form of hypertension. the ...19806249246
integration of the simian virus 40 genome into cellular dna in temperature-sensitive (n) and temperature-insensitive (a) transformants of 3t3 rat and chinese hamster lung cells.we studied the pattern of integration of the simian virus 40 (sv40) genome into the cellular dna of n-transformants (temperature sensitive) and a-transformants (temperature insensitive) derived from 3t3-fisher rat and chinese hamster lung cells. the sv40 dna was covalently linked to the cellular dna in both types of transformants. in the rat cells, most n-transformants contained sv40 sequences integrated at a single site; most a-transformants contained sv40 sequences integrated at two to five si ...19806251267
immunologic investigations of mucoid strains of pseudomonas aeruginosa: comparison of susceptibility to opsonic antibody in mucoid and nonmucoid strains.mucoid strains of pseudomonas aeruginosa, isolated from patients with cystic fibrosis, were studied for the prevalence of each of the seven fisher immunotype antigens and were compared with their nonmucoid transformants, obtained by repeated subculturing, for susceptibility to opsonic antibody. of the 30 strains tested--one from each of 30 patients--16 were typable and were tested in the opsonophagocytic assay with use of immunotype-specific rabbit antiserum; eight had significant opsonization b ...19806444976
[cell-free pseudomonas vaccine. i. enzyme properties and virulence of strains of p. aeruginosa; protective activity of their water-soluble antigens].the enzymatic (protease, catalase and gelatinase) activity and virulence of the typing strains obtained from the hungarian national collection of medical bacteria, as well as those of highly toxigenic pa-103 strain and 2 newly isolated p. aeruginosa strains were studied. no correlation between these properties of the strains was observed. aqueous extracts prepared from some of the typing strains contained soluble specific and non-specific protective antigens. the partially purified, low toxic, w ...19806778035
slime glycolipoproteins and the pathogenicity of various strains of pseudomonas aeruginosa in experimental infection.several strains of pseudomonas aeruginosa were differentiated on the basis of the surface properties of the cells. fisher immunotype, phage type, polysaccharide depolymerase type, and indirect hemagglutination reactions were used for this purpose. each strain was then studied with respect to events known to occur during the experimental infection of mice with p. aeruginosa. the virulence of the viable cells varied significantly, although all strains were virulent. glycolipoproteins were isolated ...19806777303
use of pseudomonas aeruginosa lipopolysaccharide immunoadsorbents to prepare high potency, mono-specific antibodies.potent, mono-specific anti-pseudomonas immunoglobulins were isolated from serum and lung lavage fluid from patients with cystic fibrosis using immunotype specific pseudomonas aeruginosa lipopolysaccharide (lps) substituted immunoadsorbent gel. iodinated monovalent pseudomonas lps somatic antigens, fisher immunotypes, were used as ligands for two different insoluble gel matrices. lps iodination, using the water insoluble chloroglycoluril reagent, permitted quantitation of the percent lps bound as ...19806778926
[cystoscopy (1879-1979) (centennial of a transcendental invention)].the authors make a historical review of the successive stages in man's attempt to be able to observe directly the inside of the cavities of the human body and more precisely of the bladder, which from the start long ago, led to the apparatuses invented during the first half of the 19th century (bozzini, ségalas, bonbalgini, fisher, avery, desormeaux, hacken, cruise, grünfeld, luys, etc.) until the 9th march 1879 when maximilian nitze presented in the vienna medical society and published in the j ...19806987957
studies of the immediately vascularized skin order to evaluate the effect of the nature of revascularization on survival rates of skin allografts, a rat model was devised which provided simultaneous and immediate establishment of arterial and venous blood supply to a composite skin-renal allograft. for 5 days after transplantation the skin portion of the composite grafts appeared normal, with minimal inflammation in 11 recipients. from 6 to 11 days, in 6 rats, active rejection developed with a marked inflammatory reaction of the skin-ki ...19806992906
statistical study of the fisher-race model for human rh genetics.the technique of chromosomal positioning of inheritable traits (c.p.i.t.) to project relative positions of two or more traits at more than one gene locus was employed to test the validity of the fisher-race model of rh structure. the results of statistical analysis of two large samples of rh phenotype distributions suggest that all models based on vertically related, linked alleles are invalid. on the basis of further analysis, wiener's concept of the structure of the human rh-hr gene locus appe ...19806776028
effect of n-nitrosomethylurea on substrains of fisher lymphadenosis l-5178 resistant to antitumoral antibiotics.a cytogenetic analysis of variants of fisher mouse lymphadenosis l-5178 resistant to the antitumoral antibiotics bruneomycin and rubomycin c showed that the cytogenetic characteristics of the changes in the tumor cell population correlate with the chemotherapeutic indices of the development of drug resistance. cytogenetic and kinetic analyses showed that variants of fisher lymphadenosis l-5178 resistant to bruneomycin and rubomycin c retain sensitivity to n-nitrosomethylurea (nmu). the activity ...19807437480

iodothyronine kinetic studies in the newborn lamb.metabolic clearance rates and production rates for thyroxine (t4), triiodothyronine (t3) and reverse t3 (rt3) were determined by pulse injection kinetic techniques in newborn sheep between 7 and 14 days of age. the mean metabolic clearance rate for t3 (39.6 +/- 4.5 l/m2 per day) was significantly greater than that for t4 (7.25 l/m2 per day, p < 0.001). the mean value for rt3 (27.5 +/- 2.8 l/m2 per day) also exceeded that for t4 (p < 0.001) but did not differ from that for t3. the mean production ...19807440940
[effect of concanavalin a on the splenic lymphocyte proliferative activity of germ-free rats].action of con-a on the proliferative activity of spleen lymphocytes was studied using germfree and conventional fisher rats 3-4 months of age and conventional 2-3 day old rats. the intensity of 3h-thymidine incorporation in lymphocytes of germfree and conventional animals was the same, however, the coefficient of stimulation was higher in germfree rats. lymphocytes of suckling rats had a low reactivity to con-a.19807445093
the antitumour activity of maltose tetrapalmitate compared with other immunoadjuvants, and its effectiveness after tumour surgery.the effectivenss of maltose tetrapalmitate (mtp) as an antitumour immune adjuvant was verified by its comparison with other known immunopotentiators, namely bcg, corynebacterium parvum, levamisole and pyran copolymer. copenhagen x fisher 344/crbl f1 hybrid male rats inoculated s.c. with the dunning r3327a prostatic adenocarcinoma were used as the test system. all animals treated with immunoadjuvants showed a delay in tumour appearance and inhibition of early tumour growth. mtp was found to be th ...19807459208
effects of lactose and mode of sterilization of a lactose diet on mineral metabolism in germ-free and conventional rats.mineral balances of ca, p, mg, k, na, zn, mn, cu were carried out on 6-week old fisher rats for 14 consecutive days. four lots of germfree (gf) and 4 lots of conventional (cv) rats were fed a semi-synthetic diet at weaning containing either 0 or 10 p. 100 of lactose (l). the diet was sterilized either by irradiation (i) or by autoclave (au). lactose, when added to the diet, caused very variable modifications of the mineral metabolism, depending on the mineral studied and the mode of sterilizatio ...19807349413
charge forms of wistar rat alpha-lactalbumin. a contradiction.alpha-lactalbumin was purified from the milk of wistar rats and was compared to that obtained from fisher 344 rats. alpha-lactalbumin isolated from the wistar rat exists as two forms which differ in their sialic acid content, as the desialyated forms migrate to one identical position on polyacrylamide gels. these two charge forms are identical with the charge forms ii and iii previously characterized from fisher rat alpha-lactalbumin. no evidence was found to verify previous reports that one for ...19807380837
body build and temperature tolerance: an experimental analysis of ecological 'rules'.according to current anthropological theory, the two factors that primarily determine thermoregulation in human populations are body size and body proportions, and they have found their formulation in the ecological 'rules' of bergmann and allen. in order to test the validity of these idea, buffalo and fisher rats were submitted to various levels of heat and cold. the two strains were chosen because they demonstrate maximum differences in body size and body proportions in domesticated rats. the ...19807405512

energy-linked mitochondrial transhydrogenation from nadph to nadp analogs.the mitochondrial energy-linked transhydrogenase enzyme catalyzes hydride ion transfer between nad and hadp, of which the reaction nadh leads to nadp is slow in the absence of energy and is accelerated 10-fold or more when the mitochondrial membrane is energized by atp hydrolysis or respiration. the enzyme is a proton pump and effects proton translocation coupled to hydride ion transfer from nadph to nad (earle, s.r., and fisher, r.r. (1980) j. biol chem. 255, 827-830). the present studies have ...19807430092
relationship between increased aerobic glycolysis and dna synthesis initiation studied using glycolytic mutant fibroblasts.reports from several laboratories have suggested increased rates of glycolysis play an essential part in the initiation of dna synthesis. this is based on observations that aerobic glycolysis: (1) occurs at low rate in resting mammalian cells and at very high rate in tumour cells; (2) increases rapidly after dna synthesis is initiated by addition of serum or purified growth factors, and (3) correlates with the expression of the transformed phenotype. also, specific inhibitors of aerobic glycolys ...19807432468
in vitro release of biologically active adriamycin by magnetically responsive albumin microspheres.the kinetic release of therapeutically active adriamycin from two different heat-stabilized preparations of magnetically responsive albumin microspheres (1 micron) has been evaluated using a rapid in vitro bioassay-harvesting system. release products are added to freshly plated monolayers of a malignant fisher 344 rat fibrosarcoma cell line, and the inhibition of [3h]uridine incorporation into trichloroacetic acid-precipitable material (rna) and whole cells is determined in a 6-hr microtiter ass ...19807438037
dog bite wounds and infection: a prospective clinical study.we prospectively studied 26 patients with 27 dog bite wounds who sought medical attention in the emergency department. two distinct populations were found (fishers exact test, p less than or equal to 0.001): 1) those who presented 8 hr to 12 hr post-injury were concerned about rabies or tetanus or surgical wound repair; and 2) those who presented more than 12 hr post-injury were concerned with infection. there was no difference (p > 0.05) in the bacteriology of the two groups. of all wounds, 74% ...19807425403
lung clearance of particles in two strains of rats.two strains of commonly used experimental rats were compared with regard to lung clearance of tio2 particles. the fisher 344 inbred rats retained predictably fewer particles after a 7-hr exposure than the larger outbred long-evans rats. this fact can be expected in view of the different lung size of the two strains. in addition, clearance of the retained particles was significantly slower in fisher 344 rats. differences in lung clearance capacity of different animal strains should be considered ...19807250091

successful methotrexate therapy in oral florid papillomatosis.oral florid papillomatosis is a rare syndrome, which was first described under this name by rock & fisher in 1960. the same syndrome had been previously described as papillomatosis mucosae oris carcinoides by scheicher-gottron (1958). it is a benign condition, capable of malignant degeneration. surgical excision and electrocoagulation are the most widely used therapeutic methods, despite the fact that relapse of symptoms after treatment by these methods is common. the literature comprises a few ...19807471503
[prognostic clinical criteria in comatose conditions].a total of 98 comatose patients were reclassified according to the final stage of the disease by means of the discrimination procedure after fisher. those neurological symptoms and general clinical data were ascertained that were most important for the separation. the order of the characteristics according to their contribution to the separation shows a dependence upon the time of the examination. the different distinctiveness and degree of intensity of neurological symptoms are of different imp ...19807280132
[comparison of the effect of premedication with diazepam and trazodone on anesthesia induced with althesin].interference on the part of premedication with diazepam and trazodone with althesin anaesthesia was investigated and compared by means of variance analysis according to fisher, and the x2c test according to yates, in 150 patients aged 35-45 yr in three groups of 50 during examination of the uterine cavity. no marked difference between the effects of the two drugs were noted, with two exceptions: 1) trazodone was better able to potentiate the hypnotic action of althesin, so that less was needed f ...19807219734
the c1q binding assay in systemic lupus erythematosus: discordance with disease investigate the relationship of c1q binding assay (c1qba) to disease activity in systemic lupus erythematosus (sle), a retrospective study was carried out on 232 c1qba performed in 33 patients with sle. when initial values were assessed (33 tests in 33 patients), there was no relationship between positive and negative c1qba and abnormal renal function (p = 0.482, fisher exact test). of 87 tests performed during active renal disease, 34 (39%) were positive; of 48 tests during active non-renal ...19807447962
small deep infarcts diagnosed on computed tomography.the clinical and angiographic correlations of small deep infarcts seen on computed tomography (ct) scan were studied in 297 consecutive patients. some of these showed the features described by fisher as part of the lacunar syndrome. in a large number, a source of emboli from either a cardiac or a carotid source was highly probable; in a smaller number, other vascular diseases were present. the finding of a small deep infarct on ct does not exclude the need for further investigation of a possible ...19807191500
homolateral ataxia and crural paresis: case report.homolateral ataxia and crural paresis is a recognized vascular syndrome. however, confirmation of the causative lesion rests principally on one earlier case with multiple other infarcts. we studied a patient with the clinical syndrome; computerized tomography revealed a lucency that appeared within 1 week of the infarct. localization of the lesion to the superior portion of the posterior limb of the internal capsule and thalamus is in accord with the original conclusions of fisher and cole.19807191530
statistical mechanical analysis of raman spectroscopic order parameter changes in pressure-induced lipid bilayer phase transitions.the statistical mechanical cluster theory of fisher as applied by kanehisa and tsong to phospholipid bilayers is modified to describe the effects of hydrostatic pressure on the state of an aqueous dispersion of the phospholipid dipalmitoyl phosphatidylcholine. a high pressure raman scattering cell has been built to obtain the raman spectra of aqueous dispersions of phospholipids as a function of the applied hydrostatic pressure from 0 to 100 atmospheres. predicted thermal and pressure-induced ph ...19806894876
testing pattern hypotheses on correlation matrices: alternative statistics and some empirical results.the goodness-of-fit of correlational pattern hypotheses has traditionally been assessed either with a likelihood ratio statistic (in conjunction with maximum likelihood estimation) or with a quadratic form statistic (in conjunction with generalized least squares estimates). in the present paper, several alternative statistics, based on the use of the fisher r-to-z transform, are proposed, and their performance (as well as that of the traditional statistics) is assessed in a monte carlo experimen ...198026794186
the not-so-benign miller fisher syndrome: a variant of the guilain-barré syndrome.two patients with fisher's syndrome of ophthalmoplegia, ataxia, and areflexia experienced severe weakness and respiratory distress. both patients required tracheostomy and assisted ventilation, but both made a complete recovery. fisher's syndrome is generally considered to be a benign variant of acute infectious polyneuropathy (the guillain-barre syndrome). our two patients demonstrate that the condition is not always benign.19807387472

acute and chronic effect of dietary cholic acid on colonic epithelial cell proliferation.administration of cholic acid (1.0% of the diet) to male fisher rats for 3 days resulted in increased numbers of dna synthesizing epithelial cells per colonic crypt column as compared to those found in either control or 0.2% cholic acid-fed rats. the middle third of the crypt was the area stimulated to contribute the additional proliferating cells. the maximum number of 3h-tdr-labeled cells was doubled by 24 h and migration had processed further up the colonic crypt of the 1% cholic acid-fed rat ...19817250550
age changes on bone size and mass in two strains of senescent rats.6-month-old buffalo and fisher inbred rats were compared with their respective senescent counterparts. it appeared that length as well as weight of the various sections of the skeleton increased into old age. however, in some skeletal parts, length increase was greater than weight increase, so that relative robusticity of those parts, relating weight to length, dropped. the two different strains of rats showed differences in age-related bone reactions. thus, while in humans, age-related bone los ...19817257716
the role of body mass in thermoregulation.inbred fisher and buffalo rats were raised in small and in large litters and by such litter manipulation, large- and small-bodied animals were obtained within the same strain. when the rats were exposed to extreme cold and heat, it appeared that large-bodied rats in both strains survived longer in cold and small-bodied rats survived longer in heat. the two trends were clearly evident, and individual correlations between survival time and body mass were generally significant. however, there were ...19817258339
induction of spinal cord paralysis by negative part of our investigations on late non-neoplastic injury induced by negative pi-mesons (pions), a series of studies have been performed using pion beams for the induction of spinal cord paralysis in the fisher 344 rat. groups of rats were exposed to 1, 5 or 15 daily doses of peak pions or x rays. paralysis appeared earlier after treatment with pions than after x rays even in a comparison of groups with similar final incidences. a single dose rbe for spinal cord paralysis of 1.3 was found. the ...19817260512
evaluation of megadose vitamin therapy in an experimental brain tumor.a mixture of vitamins c and b12 in high dosage, which has been reported to eradicate ascites tumors in rats, was tested for its antineoplastic effect against the l9 glioma in fisher cdf strain rats. no difference in survival time between animals receiving the vitamin mixture and controls could be demonstrated. possible reasons for the different response to therapy in the two experimental tumor systems are discussed.19817280989
neuron numbers in locus coeruleus do not change with age in fisher 344 rat.counts of neurons in locus coeruleus of fisher 344 rats of ages from 12 to 32 months showed no loss with advancing age. species comparisons of age changes in locus coeruleus neuron counts and measures of catecholamine systems suggested that the human and nonhuman primate locus coeruleus shows age changes and seen in rodent locus coeruleus. it is suggested that although rodent models of human aging have value under some circumstances, rodent and primate brain should not be considered equivalent w ...19817266740
sterol metabolism in the rat: effect of alcohol on sterol metabolism in two strains of rats.sterol metabolism studies using a combination of isotopic and chromatographic procedures were carried out in two strains of rats fed 5% ethanol (36% of calories) in the diet. feeding ethanol to the fisher rat over 17 days produced no significant changes in body weight. cholesterol levels in various tissues were elevated in the ethanol-fed group: plasma cholesterol, +61%; liver cholesterol, +47%; and bile cholesterol, +57%. the alcohol-fed fisher rat showed several changes in sterol metabolism ov ...19817018302
field studies: pseudomonas pneumonia of mink.epizootics of pneumonia in mink caused by pseudomonas aeruginosa were investigated to characterize the serotype of organisms and to identify possible predisposing factors. most epizootics were associated with p aeruginosa fisher serotype 1, and a few were associated with 3 other serotypes. there were no predisposing factors identified that could be used to differentiate farms affected and those not affected with pseudomonas pneumonia. cultural studies indicated that p aeruginosa was present in m ...19816803621
correlation studies of entero-set 20, api 20e and conventional media systems for enterobacteriaceae identification.the entero-set kit (fisher diagnostics) is a 20-biochemical-test system used in the identification of members of the enterobacteriaceae. this kit was compared with the api 20e (analytab products) and conventional media systems, using 505 (303 stock and 202 clinical) strains of enterobacteriaceae. when the entero-set and api 20e results were compared with those of the conventional media system, the entero-set performed as well as the api 20e in overall identification. comparison of common biochem ...19817007414

diagnosis of bacteremia in children by quantitative direct plating and a radiometric procedure.during a 1-year period, three bacteriological systems for detecting bacteremia in children were analyzed, namely, the bactec system (johnston laboratories, inc., cockeysville, md.), the fisher/lederle bottle (lederle diagnostics, pearl river, n.y.), and a direct plating method of blood termed quantitative direct plating (qdp). of 2,123 blood cultures, 135 (6.4%) were positive; haemophilus influenzae type b, neisseria meningitidis, and streptococcus pneumoniae accounted for 3.4%, representing 61 ...19816787069
inhibition of prostate tumor growth in two rat models by chronic administration of d-trp6 analogue of luteinizing hormone-releasing hormone.we have investigated the effect of the d-trp6 analogue of luteinizing hormone-releasing hormone (lh-rh), a superactive analogue of lh-rh, on the growth of two different models of prostate tumors in rats. chronic administration of d-trp6-lh-rh in a dose of 25 micrograms/day for 14-21 days significantly inhibited the growth of the chemically induced squamous cell carcinoma 11095 in fisher 344 male rats. the weights of the ventral prostate and testes were also significantly reduced by treatment wit ...19816458815
transformation of rat cells by an altered polyoma virus genome expressing only the middle-t protein.a modified polyoma virus genome has been constructed which can encode the middle-t protein, but not the large-t or small-t proteins. this was achieved, starting with the full length viral dna inserted into a plasmid vector, by replacing a small genomic restriction fragment spanning the middle-t intervening sequence with the equivalent fragment from a cloned partial cdna copy of the middle-t protein mrna. transfection of the modified viral dna into cultured rat cells efficiently induced the forma ...19816265803
collagen lysyl oxidase activity in the lung increases during bleomycin-induced lung fibrosis.intratracheal administration of bleomycin caused pulmonary fibrosis in rats. bleomycin sulfate (640 micro grams/165 g b.wt. in 0.5 ml of sterile saline) was instilled intratracheally into male fisher 344 rats (169 +/- 5 g), whereas control animals received 0.5 ml of sterile saline by the same route. one, 3, 7, 14, 28 and 322 days after instillation, the animals were killed, the lungs were homogenized in 6 m urea, 0.01 m nacl, 0.001 m potassium phosphate (ph 8.3) and the homogenates were subjecte ...19816170751
monoclonal antibodies against antigens displayed on a progressively growing mammary tumor.we have produced lymphocyte hybridomas between mouse myeloma cells and either spleen cells of c3h/f/c57bl/6 mice bearing the mm5mt/c1 tumor-producing murine mammary tumor virus (mmtv) or spleen cells from fisher rats inoculated with the same tumor. two classes of hybridoma-secreted monoclonal antibodies were obtained. in the first class are ivc11, iiia1, and ve7, each of which precipitated a 52,000-dalton protein from 125i-labeled purified preparations of mmtv and [3h]glucosamine-labeled mm5mt/c ...19816264447
enzymatic and ultrastructural study of lysosomes in rats bearing radiation-induced thyroid follicular carcinoma.radiation-induced well-differentiated and poorly differentiated follicular thyroid cancers were transplanted into the intrascapular fat pads of male fisher 144 rats. the tumors grew in the recipient rats and after a time interval were removed and studied along with normal rat thyroids for lysosomal activity and ultrastructural characteristics. plasma from experimental and control rats was also studied for lysosomal activity. rats with radiation-induced thyroid carcinoma had a decrease in growth ...19816109795
propagation of korean hemorrhagic fever virus in laboratory rats.korean hemorrhagic fever virus (khfv) has been adapted to the wistar and fisher strains of rats. infection was detected by the appearance of specific antigen in the lung tissue of the infected rats at 14 to 64 days after inoculation and by the appearance of circulating antibodies in ther serum which reacted specifically with khfv antigen in the lungs of infected apodemus agrarius subsp. coreae 3 weeks after inoculation. distribution of antigen in rat tissues as determined by immunofluorescent st ...19816111538

fisher syndrome in childhood.three children, age 2, 7, and 12, developed fisher syndrome: inability to walk because of ataxia, complete areflexia, and ophthalmoplegia. ptosis was prominent in all the children, but the pupillary response to light was affected only in one child. limb weakness was never present, and sensation normal. one patient was obtunded for several days. two had prodromal upper respiratory tract illnesses, and the third patient was bitten by an insect 2 days before her symptoms began. cerebrospinal fluid ...19817194971
effect of cigarette smoking on susceptibility to lung cancer.fisher first suggested that genetic predisposition to lung cancer is a more important factor than cigarette smoking, and that therefore one may smoke. recently, this thesis has been defended strongly by burch. here, a literature survey has been done that indicates that the genetic susceptibility for development of lung cancer varies between individuals. but it is wrong to conclude from this that therefore one may smoke. such a conclusion only would be valid, if there was a close relationship bet ...19817465162
[not available].this essay surveys the development of fertility measurement techniques since the mid 17th century, posing the question of why their development lagged so far behind those for mortality and the partial answer that through its brief history fertility analysis has repeatedly been put to the service of noxious causes and aberrant theories. the work begins with a brief review of the development of mortality statistics, beginning with graunt's work in london, and goes on to examine early theories of p ...198111634857
