  • Title: [Effect of combined exposure to hypokinesia and gravitational stress on the structure of the wall of the renal vein].
    Author: Konkina NI.
    Journal: Arkh Anat Gistol Embriol; 1978 Jun; 74(6):80-4. PubMed ID: 678140.
    Abstract:
    Renal veins from 25 rabbits were investigated by means of imbedding in paraffin with subsequent hematoxylin--eosin staining, after Van Gieson and with fuchselin after Hart. Prolonged hypokinesia (over 3 weeks) with subsequent single application of gravitational overloading was stated to produce some structural changes in the wall of the renal vein. They are manifested as loosening of the middle vascular sheath with vacuolization of myocytes and outgrowth of its elastic elements. Hypokinesia of longer duration (8 weeks) with subsequent gravitational overloading produces atrophy of smooth muscle tissue in the middle sheath of the venous wall that brings about decreasing in tonus of the wall of the renal vein.
