bronchus-associated lymphoid tissue (balt) in the laboratory-bred and wild rat, rattus juvenile wild rats, bronchus-associated lymphoid tissue (balt) development was similar to that seen in adult specified-pathogen-free rats. in adult wild rats the balt was widespread. in one animal infected with a mycoplasma-like organism, a region of bronchoepithelium overlying a large balt nodule was seen, through which lymphocytes appeared able to pass to make direct contact with the bronchial lumen: the significance of this observation is discussed. there was no evidence of infection in lu ...1979162238

longitudinal effect of captopril on aortic and arteriolar development in normotensive explore the effect of chronic converting enzyme inhibition on the macro- and microcirculation, normotensive rats were chronically given 100 mg/kg/day of captopril in their drinking water beginning one day before uninephrectomy. cremaster arteriolar dimensions were measured 2, 4, or 8 weeks later by intravital microscopy, before and after topical application of 10(-3) m adenosine. mean blood pressure were significantly decreased at 4 (17%) and 8 (18%) weeks in treated rats vs age-matched contr ...19921304458
cytomegalovirus colitis in an older woman, successfully treated with ganciclovir.cytomegalovirus (cmv) infections are usually found in immunocompromised persons and rarely present in those who are immunocompetent. we report a case of cmv colitis in an elderly woman presenting with delirium, prolonged fever, and diarrhea. treatment with ganciclovir, an antiviral agent, resulted in resolution of the colitis within 3 weeks without noticeable side effects. older adults may be more susceptible to cmv infection by virtue of age-related changes in immune function. the possibility o ...19921317403
[postcoital uterine microbe colonization and endometritis in the mare].in the mare, natural breeding is associated with bacterial contamination of the reproductive tract. the purpose of this study was to examine postcoital bacterial contamination and the resulting inflammatory response of the uterus. uterine swabs for bacteriological and cytological examination were obtained from 80 mares. each mare was sampled once between 4 and 69 hours postbreeding. in mares which did not conceive, sampling was repeated at the following estrus. the findings were compared with th ...19911948985

diagnosis of aelurostrongylus abstrusus and dirofilaria immitis infections in cats from a human shelter.during a 6-month period, 108 sexually mature stray cats were euthanatized at a humane shelter in alabama. aelurostrongylus abstrusus was identified in 20 of the cats (18.5%) by baermann fecal examination, necropsy, or histologic examination. the baermann fecal examination was a more sensitive test for aelurostrongylosis than was necropsy or histologic examination. thoracic radiography was useful in identifying infected cats, but was a less sensitive and more nonspecific method of detection than ...19883366677
paired helical filaments from alzheimer disease patients contain cytoskeletal components.neurofibrillary tangles from alzheimer disease patients share antigenic determinants with neurofilaments and microtubule-associated proteins, as shown by light microscopy immunocytology. the present study addresses the issue of whether these determinants are located on the paired helical filaments or on other components of the neurofibrillary tangle. sections from postmortem brains from alzheimer disease patients were stained by using bodian's silver method or immunostained by using poly- and mo ...19853889918

regional sensitivity of neuroleptic receptors to sub-acute soman intoxication.sub-acute exposure to anti-cholinesterase organophosphorous compounds induces, in humans, cognitive and emotional deficits which include depression, anxiety, emotional lability, and schizophrenic-like symptoms. neuroleptic drugs used to treat similar clinical conditions bind to serotonergic (s2) and dopaminergic (d2) receptors, suggesting that these sites are involved in the psychiatric consequences of organophosphate exposure. rats were given saline or soman (50 micrograms/kg, sc) on a sub-acut ...19853995358
unusual pharyngeal lesion causing dysphagia.a 58-year-old man was evaluated for a 42-year complaint of a pharyngeal foreign body sensation whenever he ate. examination revealed normal anatomy at rest but diffuse hypopharyngeal distension with valsalva's maneuver. his past history was remarkable for an infectious illness, possibly diphtheria. we speculate that this unusual case most likely represents a postdiphtheritic selective pharyngeal paralysis and present his case, radiographic findings, and a discussion of the differential diagnosis ...19873674649
the different effects of recombinant human tumor necrosis factor on rat fibrosarcoma sublines.the antitumor effect of recombinant human tumor necrosis factor (rh-tnf) on two clones of rat fibrosarcoma with different metastatic potential to lymph nodes was examined. the colony formation of clone a, which has high metastatic potential, was completely inhibited by continuous exposure to rh-tnf at 50 u/ml. in contrast, colony formation of clone g, which has low metastatic potential, was not inhibited by high concentrations of rh-tnf (10,000 u/ml). the inhibitory effect of rh-tnf on colony fo ...19873594481

prevention of rectal cancer induced by n-nitrosobis(2-oxopropyl)-amine by exogenous testosterone in mrc rats.rectal carcinogenicity of n-nitrosobis(2-oxopropyl)amine (bop) in male mrc wistar rats was shown to be inhibited by exogenous testosterone (t) when the hormone was given during, but not after, administration of the carcinogen. this effect was independent of the dose and frequency of bop, which was given either weekly for 20 weeks orally or daily for 3 days subcutaneously. since, except for prostatic cancer, the incidence and the patterns of other bop-induced tumors were not altered by t, this ho ...19892805225

age-dependent relaxation of gene repression: increase of endogenous murine leukemia virus-related and globin-related rna in brain and liver of mice.a progressive loss in the ability of cells to maintain their normal specialized states of differentiation could be the common denominator underlying much of the physiology and pathology associated with the mammalian aging process. we investigated this possibility by searching for an age-dependent derepression of endogenous genes in tissues in which they are not normally expected to be expressed. complementary dna (cdna) probes to globin genes and to the murine leukemia type c rna virus (mulv) ge ...1978212751

estimation of missing cone data in three-dimensional electron microscopy.the range of tilt angles for which projected images of two-dimensionally periodic specimens can be obtained in electron microscopy is limited both by technical aspects, such as goniometer design, and by the more fundamental limitation of object thickness. the lack of a full set of projections causes a missing cone in the reciprocal space data for the object, which will give an anisotropic resolution in a three-dimensional reconstruction and may cause the quality to be impaired by spurious featur ...20113244969
