OBJECTIVE: To study the effect of hesperidin and rutin on oxidative modification of high density lipoprotein (HDL) in vitro. METHODS: HDL was isolated from healthy human plasma by sequential ultracentrifugation, and was oxidized by copper ions. The inhibitory effects of hesperidin and rutin on HDL oxidative modification were valued by the formation of malondialdehyde (MDA). RESULTS: Hesperidin and rutin significantly inhibited copper-induced oxidation of HDL in a dose-dependent manner. CONCLUSION: Both hesperidin and rutin can prevent HDL from copper-induced oxidative modification in vitro. This result suggests that they might have antiatherogenic effect.

Objective To study the effects of monocyte chemotactic protein-1(MCP-1) on the growth of human umbilical vein endothelial cells (hUVEC). Methods hUVEC were cultured in vitro and identified. hUVEC that grew vigorously were stimulated for 24 h or 48 h respectively with MCP-1(0.1, 1.0, 10, and 100 ?g/L). The survival rate of hUVEC was first detected by MTT assay. The cell cycle and DNA content were detected and analyzed by flow cytometry. Results hUVEC were isolated from human umbilical veins and cultured, and then identified by immunofluorescence and immunohistochemistry with factor Ⅷ and KDR. MCP-1 induced the apoptosis of hUVEC in a dose-dependentmanner and a time-dependentmanner (P
