  • Title: [Lipid peroxidation injury to red blood cells during extracorporeal circulation: mechanism and protection].
    Author: Jia B, Zhang ST, Li GF.
    Journal: Zhonghua Yi Xue Za Zhi; 1994 Nov; 74(11):689-91, 711. PubMed ID: 7866907.
    Abstract:
    Twelve dogs were subjected to cardiopulmonary bypass with membrane oxygenator for 120 minutes. The effect of lipid peroxide injury on red blood cells was studied by measurement of plasma and erythrocyte membrane lipid peroxide, deformabioity of erythrocyte, plasma free hemoglobin, superoxide dismutase, Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase of erythrocytes. The effect of vitamin E on red blood cells was also investigated. The findings indicated that vitamin E might protect red blood cells from lipid peroxide injury during extracorporeal circulation. The mechanism of damage effect of lipid peroxide and the protective effect of vitamin E on red blood cells were briefly discussed.
