    Notizen: Summary The presence of the CRF-containing neurons in the hypothalamus was investigated in four different species (cats, dogs, pigs, and monkeys) by the peroxidase-antiperoxidase technique using specific anti-serum to CRF. In all animals examined, CRF-containing perikarya were found mainly in the paraventricular and supraoptic nuclei, and a small number of the immunoreactive cells were observed in the accessory supraoptic nucleus and the lateral hypothalamic area. The size of the CRF-containing perikarya ranged from 20–35 μm in diameter. These findings suggest that the magnocellular paraventricular and supraoptic nuclei are the center not only of the classical neurosecretory system for the production of the posterior lobe hormones, but also that of the CRF neuronal system.

    The main HTLV-I-harboring cells in the muscles of viral carriers with polymyositis are not macrophages but CD4+ lymphocytes (1996)

    Notizen: Abstract We have analyzed muscle biopsy specimens from polymyositis patients who are also positive for human T cell lymphotropic virus type I (HTLV-I) using both immunohistochemistry for surface antigens of lymphocytes and macrophages and in situ polymerase chain reaction for HTLV-I proviral DNA on the same sections. We found HTLV-I in CD4+ cells but not in macrophages. This finding suggests that most of the HTLV-I-containing CD4+ cells are not macrophages but lymphocytes.

    In situ polymerase chain reaction detection of HTLV-I provirus and expression of the p53 tumor suppressor gene in infiltrating cells in skeletal muscle from a patient with adult T cell leukemia (1995)

    Notizen: Abstract We report the pathological changes in skeletal muscle from a patient with acute adult T cell leukemia (ATL). HTLV-I provirus was detected in infiltrating cells using in situ polymerase chain reaction in frozen sections. Furthermore, aberrant expression of the p53 protein was observed in the infiltrating cells. As p53 protein was not observed in mononuclear inflammatory cells in patients with polymyositis, expression of the p53 protein was considered to be one of the characteristic findings in ATL cells. This is the first direct detection of ATL cells in skeletal muscle.

    Age-related changes in the compound action potentials of the eighth nerve in guinea pigs (1997)
    Springer

    Notizen: Abstract The eighth nerve compound action potential (CAP) in 95 guinea pigs was measured using click stimuli to investigate age-related changes in their neural auditory thresholds. The animals were separated into three groups: group A (n = 43, 86 ears; 2–4 months old); group B (n = 29; 58 ears, 13–15 months old); and group C (n = 23; 46 ears, 23–25 months old). With increasing age, a gradual elevation of CAP thresholds was clearly seen among the three groups. The negative peak (N1) latencies of the CAP were prolonged, and the N1 amplitudes of the CAP decreased. There were significant differences in N1 latencies among the three groups and in N1 amplitudes between groups A and B, and between groups A and C. However, the rate of decline of the thresholds as well as the input-output function curves of the CAP varied in some of the oldest animals, suggesting that there were some individual differences in degenerative aging processes of the auditory system.

    Immunohistochemical identification of neurons containing corticotropin-releasing factor in the rat hypothalamus (1983)

    Notizen: Summary A specific rabbit anti-CRF serum and the immunoperoxidase technique were used to show that CRF-containing neurons are mainly distributed in the paraventricular and supraoptic nuclei of the rat hypothalamus. In addition, immunoreactive neurons are scattered in other hypothalamic regions. These neurons are 20–30 μm in diameter. From the present and previous investigations it may be concluded that the hypothalamic magnocellular nuclei, i.e., paraventricular and supraoptic, and other hypothalamic accessory nuclei, are the producing sites not only for vasopressin and oxytocin, but also for corticotropin-releasing factor.

    Differences in the distributional pattern of CRF-, oxytocin-, and vasopressin-immunoreactive nerve fibers in the median eminence of the rat (1983)

    Notizen: Summary Conspicuous differences in the distributional pattern of nerve fibers containing corticotropin-releasing factor (CRF) or posterior lobe hormones, respectively, were shown in the median eminence of the adult male rat by means of immunoperoxidase histochemistry, with the use of anti-CRF, anti-oxytocin, and anti-vasopressin sera. In the rostral and central divisions of the median eminence, a high concentration of CRF-immunoreactive nerve fibers was found in the median portion of the external layer; these fibers terminated on the capillary loops of the hypophysial portal system. In the caudal division of the median eminence, the CRF-immunoreactive nerve fibers were located in the median to paramedian portions of the external layer. Numerous oxytocin- and vasopressin-immunoreactive nerve fibers were observed evenly distributed throughout the internal layer of the median eminence. In the external layer, a small number of the oxytocin- and vasopressin-containing nerve fibers was found around the capillary loops, particularly in the median to paramedian portions. The distributional patterns of the CRF and the posterior lobe hormones in the hypothalamo-hypophysial system and their functional interrelationship are discussed.

    Notizen: Summary The occurrence of CRF (corticotropin-releasing factor)-immunoreactive nerve fibers in the circumventricular organs of adult male monkeys, Macaca fuscata, was studied on serially sectioned brains, by means of the peroxidase-antiperoxidase technique in combination with a highly specific and sensitive CRF antiserum. CRF-containing nerve fibers were found in high concentrations in the infundibulum and, in addition, in small numbers in the posterior lobe, organum vasculosum laminae terminalis, subfornical organ, and area postrema; they were missing in the pineal body and the subcommissural organ. The CRF immunoreactive nerve fibers distributed in these organs were located in the proximity of the blood vessels.
