  • Title: The effects of stress on the hypothalamic and neurohypophysial vasopressin content and plasma renin activity in rats.
    Author: Olczak S, Guzek JW.
    Journal: Acta Physiol Pol; 1983; 34(1):47-55. PubMed ID: 6356787.
    Abstract:
    Rats were stressed by immobilization of exposure to cold. The hypothalamic vasopressor activity increased in immobilized animals and did not change in cold-exposed ones. The neurohypophysial vasopressor potency increased in cold-exposed animals and decreased following immobilization. The plasma renin activity in immobilized animals was significantly lower when compared with the respective controls. It seems, therefore, that different kinds of stress (cold exposure and immobilization) may cause different responses of the hypothalamo-neurohypophysial system.
