Nitric oxide in paraventricular nuclei of rat hypothalamus under extreme conditions

Academic Article

Abstract

  • The activity of nitroxide synthetase (NOS) was studied histochemically and levels of oxytocin and vasopressin immunocytochemically in rat hypothalamus paraventricular nuclei in on-earth experiments simulating space flight conditions with landing. Colonization of oxytocin and NOS was found in large-cell neurons of paraventricular nuclei. After 15 days under conditions of simulated microgravitation followed by 1-day double gravitation and a short-term (1 day) macrogravitation, activities of NOS and content of neuropeptides increased in large-cell neurons of paraventricular nuclei of experimental animals. ©1998 Plenum Publishing Corporation.
