    Different responses of the isolated canine coronary artery superfused with blood or Krebs-Henseleit solution (1984)

    Notizen: Summary Responses of ring segments of the isolated canine coronary artery superfused with arterial blood from a donor dog were compared with responses of segments superfused with Krebs-Henseleit (K-H) solution. KCl (1–30 mg) caused contraction in a dose-dependent manner both in K-H solution- and in blood-superfused preparation. However, CaCl2 (1–100 mg) and nifedipine (0.1–30 μg) contracted and relaxed, respectively, only blood-superfused preparation but not K-H solution-superfused one. These results show that even in the same region of the coronary artery, different superfusates result in different responses to contracting or relaxing agents. This difference may be explained by the idea that Ca2+-channels are activated and endow basal tension in blood-superfused preparations, but not in K-H solution-superfused ones.

    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.

    CRF-immunoreactive nerve fibers in the circumventricular organs of the monkey, Macaca fuscata (1983)

    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.
