  • Title: [Ultrastructure of the wall of the femoral artery in rats with chronic regional arterial hypotension].
    Author: Kaufman OIa, Shenderov SM, Pozdniakov OM.
    Journal: Biull Eksp Biol Med; 1981 Apr; 91(4):502-5. PubMed ID: 7260371.
    Abstract:
    In experiments on rats a lowering of the arterial pressure in the vessels of the body posterior was attained by occlusion of the aorta distally to the ostia of renal arteries. Twelve days after the operation there occurred a significant thinning out of the muscle layer and intermuscular septa in the wall of the femoral artery. Also, there was a disappearance of extracellular matrix vesicles usually seen in great numbers in tunica media of the artery. The animals with arterial hypotension of one- and three-month standing manifested a negligible number of extracellular vesicles; the thickness of the muscle layers and intermuscular septa increased but remained far less than normal.
