regulation of hippocampal 5-ht1a receptor gene expression by dexamethasone.the effect of dexamethasone, a selective gr agonist, on hippocampal, 5-ht1a receptor mrna expression and 5-ht1a binding was examined using in situ hybridization histochemistry and in vitro receptor autoradiography. one week after adrenalectomy, both 5-ht1a receptor mrna expression and 5-ht1a binding were increased throughout the hippocampus. administration of dexamethasone at the time of adrenalectomy significantly attenuated the increases in 5-ht1a mrna expression in all hippocampal subfields ( ...19947916919
comparison of popliteal lymph node responses in various strains of rats.outbred (namely wistar and sprague-dawley) and inbred (wistar-furth, lewis, fisher 344 and brown-norway) strains of rats were screened for their responses to reference compounds in the popliteal lymph node (pln) assay. streptozotocin and diphenylhydantoin gave positive responses as evidenced by increased weight and cellularity indices in all strains used whereas procainamide, isoniazid and barbital consistently gave negative responses. although these findings overall are in agreement with previo ...19947917501
low normal alpha-1-antitrypsin serum concentrations and mz-phenotype are associated with byssinosis and familial allergy in cotton mill workers.recent studies have shown a close association between byssinosis and airborne endotoxin concentrations. endotoxin might induce byssinosis through the release of biochemical mediators as the broncheoalveolar surface. alpha-1-antitrypsin (alpha-1-a) which neutralizes enzymes released by granulocytes is known to be important. this study evaluates the possible importance of alpha-1-a concentration and the heterozygosity (pi-s and pi-z alleles), in the prevalence of byssinosis and familial allergy. 2 ...19947920693
inflammatory neuropathies.although not quite as well protected as in the cns, nerve fibres in peripheral nerves are relatively protected from systemic immune responses and inflammatory reactions by the specialized endoneurial endothelial and perineurial barriers. expression of mhc class ii molecules is restricted to a few macrophage-like cells. compared with peripheral nerve trunks, there are more of these cells and more permeable blood vessels in the dorsal root ganglia and spinal roots. these are sites of predilection ...19947921591

[a statistical mean dyad test (tt-criteria for comparison of mean trends of two samples)].the authors claim that widely used statistic tests (student, berence-fisher, wilcoxon-mann-whitney, etc.) may fail to detect differences in average trends. a new statistical tt-test is suggested for such situations when samples are compared belonging to essentially different distributions and one of these distributions is bimodal or u-shaped. this test consists in comparison of the arithmetic means calculated not for the whole sample but separately for values higher and lower than the respective ...19947921822
oxygen free radical activity in experimental colonic carcinoma.oxygen free radical activity has been implicated in carcinogenesis through dna lysis. this study measured chemiluminescence and superoxide dismutase (sod) inhibition as an index of oxygen free radical activity in azoxymethane-induced colonic carcinoma. after 3 weeks of acclimatization, ten fisher 344 rats were injected with azoxymethane (7 mg kg-1 week-1) over 10 weeks. all animals were killed at 37 weeks and colonic mucosa (5-25 mg wet weight) was sampled from sites of histologically confirmed ...19947922065
physicians in health care management: 10. managing conflict through negotiation.the recent focus on collaborative relationships in health care means that people and groups must cooperate to accomplish clinical and management tasks. this increasing interdependence may also cause increased organizational conflict. the management of conflicts is critical to the effectiveness of an organization. negotiating strategies, based on fisher and ury's method of "principled negotiation," include establishing superordinate goals, separating the people from the problem, focussing on inte ...19947922944

parental imprinting of rat insulin-like growth factor ii gene promoters is coordinately regulated.the insulin-like growth factor ii (igf-ii) gene is parentally imprinted in the mouse and human species. by following the inheritance of natural polymorphisms of igf-ii mrna, we demonstrated that the tissue-specific parental imprinting of the igf-ii gene is conserved in the rat. the expression of the paternal igf-ii allele exceeded by more than 3 orders of magnitude that of the maternal allele in livers of 3-day-old wistar x fisher interstrain rat crosses. in contrast, the two alleles were both e ...19947929045
inter- and intra-site heterogeneity in the expression of fetal-like phenotypic characteristics by gingival fibroblasts: potential significance for wound healing.we have previously reported that fetal and adult skin fibroblasts display distinctive migratory phenotypes on 3-d collagen substrata and that these behavioural characteristics may be quantified by a function defined as the cell density migration index (cdmi). subsequent work indicated that this difference in migratory phenotype was due to the production by fetal fibroblasts of a migration stimulating factor (msf) that is not produced by normal adult skin fibroblasts. we now present data indicati ...19947929639
the effect of 6-months l-deprenyl administration on pineal mao-a and mao-b activity and on the content of melatonin and related indoles in aged female fisher 344n rats.six months of administration of the selective mao-b inhibitor, selegiline (l-deprenyl 0.25 mg/kg, s.c.) to aged female fisher 344n rats suppressed mao-a as well as mao-b activity and increased serotonin (substrate for melatonin biosynthesis) and n-acetylserotonin (immediate melatonin precursor) levels in pineal glands taken from the animals during the night. daytime values were unchanged by the treatment. the data suggest that stimulation of pineal melatonin biosynthesis might be one of the cons ...19947931233
herpes simplex brainstem encephalitis with a relapsing course.we report a patient with a relapsing form of acute brainstem encephalitis. pathological examination demonstrated necrotizing encephalitis in the cerebral cortex and, more pronounced, throughout the diencephalon, as well as in the pes pontis. neurons and glial cells in the cerebral cortex and brainstem contained herpesvirus antigens. the clinical interrelationship of brainstem encephalitis, miller fisher syndrome and landry-guillain-barré syndrome is discussed.19947931437
the effect of age on halothane-induced alterations of contractility in isolated rat aorta.aging is implicated as a factor which increases the susceptibility to volatile anesthetic-induced depression of the cardiovascular system. however, little is known regarding mechanisms responsible for this enhanced depression. current experiments examined the effects of 1.2 and 2.4 vol.% halothane on norepinephrine-induced contractility in endothelium-intact and -denuded aortic preparations isolated from 4-, 14-, and 24-month-old fisher-344 rats. prior to exposure to halothane, endothelium remov ...19947934208
activation of cyclin-dependent kinase 4 (cdk4) by mouse mo15-associated kinase.the assembly of functional holoenzymes composed of regulatory d-type cyclins and cyclin-dependent kinases (cdks) is rate limiting for progression through the g1 phase of the mammalian somatic cell cycle. complexes between d-type cyclins and their major catalytic subunit, cdk4, are catalytically inactive until cyclin-bound cdk4 undergoes phosphorylation on a single threonyl residue (thr-172). this step is catalyzed by a cdk-activating kinase (cak) functionally analogous to the enzyme which phosph ...19947935441

induction of differentiation in human promyelocytic hl-60 leukemia cells activates p21, waf1/cip1, expression in the absence of p53.the melanoma differentiation associated gene, mda-6, which is identical to the p53-inducible gene waf1/cip1, encodes an m(r) 21,000 protein (p21) that can directly inhibit cell growth by repressing cyclin dependent kinases. mda-6 was identified using subtraction hybridization by virtue of its enhanced expression in human melanoma cells induced to terminally differentiate by treatment with human fibroblast interferon and the anti-leukemic compound mezerein (jiang and fisher, 1993). in the present ...19947936668
importance of margin status in outcome of breast-conserving surgery for carcinoma.the importance of margin status in breast-conserving therapy (bct) for breast cancer remains unclear. we reviewed our experience with bct to determine the risk of local recurrence as a function of margin status.19947940156
doppler flow measurement in coronary artery bypass grafts and early postoperative clinical outcome.the present investigation attempts to correlate flow measurements made intraoperatively in coronary bypass grafts with clinical outcome. a total of 352 consecutive patients undergoing isolated coronary artery surgery underwent hemodynamic assessment of their bypass grafts (328 internal thoracic artery and 582 saphenous vein grafts) at the end of cardiopulmonary bypass (cpb) by using a 8 mhz pulsed doppler ultrasound flowmeter. the total patient population was divided into three groups of distinc ...19947940489
mono-(2-ethylhexyl) phthalate suppresses estradiol production independent of fsh-camp stimulation in rat granulosa cells.di-(2-ethylhexyl) phthalate (dehp) exposure suppressed preovulatory granulosa cell estradiol production in adult cycling rats. the active metabolite of dehp, mono-(2-ethylhexyl) phthalate (mehp), suppressed follicle-stimulating hormone (fsh)-stimulated camp and progesterone production in cultured rat granulosa cells. to examine how dehp altered granulosa cell estradiol production, the effects of mehp were studied in cultures of rat granulosa cells. granulosa cells were obtained from des-implante ...19947940537
issues in biomedical statistics: analysing 2 x 2 tables of frequencies.how best to analyse statistically experimental results that are set out as a 2 x 2 table of frequencies has been debated by statisticians for more than 50 years. the main issue is what framework of statistical inference should be adopted. the design of most biomedical experiments that result in 2 x 2 tables of independent observations is compatible with the randomization model of inference and with the fisher exact test. it is rare that the neyman-pearson population model is applicable and that ...19947945088
intercellular adhesion molecule-1 and leukocyte function-associated antigen-1 are involved in protection mediated by cd3+tcr alpha beta- t cells at the early stage after infection with listeria monocytogenes in rats.to investigate the significance of intercellular adhesion molecule-1 (icam-1) and leukocyte function-associated antigen-1 (lfa-1) in host defense against infection with intracellular parasites, we examined the effects of in vivo pretreatment with mabs to icam-1 (1a29) and lfa-1 alpha (wt-1) on the protection against infection with listeria monocytogenes in fisher f344/n rats. expression of icam-1 and lfa-1 alpha molecules on t cells in spleen, liver and peritoneal cavity of rats was down-regulat ...19947947463
the exact analysis of contingency tables in medical research.a unified view of exact nonparametric inference, with special emphasis on data in the form of contingency tables, is presented. while the concept of exact tests has been in existence since the early work of ra fisher, the computational complexity involved in actually executing such tests precluded their use until fairly recently. modern algorithmic advances, combined with the easy availability of inexpensive computing power, has renewed interest in exact methods of inference, especially because ...19947952429
