title: [Protective effect of the antioxidants selenium, vitamin E, and superoxide dismutase on cultured human endothelial cells (ECs) injured by lipid peroxidation].
abstract: Lipid peroxidation was induced in cultured human ECs with cumene hydroxide and the protective effect of antioxidants (selenium, vitamin E and SOD) on endothelial cell injury by lipid peroxidation was investigated. The results showed that after administration of antioxidants (Se, Vit E and SOD), concentration of LPO in ECs induced by cumene hydroperoxide was reduced markedly while 6-Keto-PGF1 alpha content in the medium was increased and cell injury was alleviated. These results indicate that through the protective effect on ECs against lipid peroxidation, antioxidants (Se, Vit E and SOD) might play an important role in retarding the process of atherogenesis.
