    Journal: Kosm Biol Aviakosm Med; 1977; 11(5):72-6. PubMed ID: 909275.
    Abstract:
    The hypothalamic-pituitary neurosecretory system and the kidneys of rats flown for 22 days and sacrified on the R+1 and R+26 days were studied morphologically. By histological, histochemical and morphometric measurements an increased activity of the hypothalamic-pituitary neurosecretory system and the juxtaglomerular apparatus of the kidneys was shown. The changes were reversible and by the R+26 day returned to normal. The above changes can be induced not only by space flight effects but also by readaptation to 1 g.
