  • Title: [Biomechanical properties of arteries in experimental hypotensive rats].
    Author: Jiang Z, Li H, Liu B, Teng Z, Qing K.
    Journal: Sheng Wu Yi Xue Gong Cheng Xue Za Zhi; 2001 Sep; 18(3):381-4. PubMed ID: 11605494.
    Abstract:
    To study the changes of biomechanical properties after arterial remodeling in hypotension, a model of hypotension was established in rats by constricting the abdominal aorta below the orifice of the left renal artery. The change of opening angles of the abdominal aorta, femoral artery and anterior tibial artery, and the compliance of the abdominal aorta were studied. The relationship between the pressure and volume of the abdominal aorta were also observed in vivo. The results show that non-uniformal remodeling of the hypotensive artery induces the reduction of opening angles in the zero-stress state, the C/E rate of the abdominal artery decreases while the compliance increases.
