| Abstract: | Lipid peroxidation was initiated in cultured human endothelial cells (ECs) with diamide and the protective effect of selenium on ECs were investigated. The results showed that after treatment with selenium, concentration of lipid peroxide in ECs induced by diamide was reduced markedly while prostacylin content in the medium was increased and morphological injury to ECs was alleviated. These results indicated that selenium could protect ECs from lipid peroxidative injury and might play an important role in retarding the process of atherosclerosis. |
