    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.

    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.
