摘要

Conclusion: O_x-LDL induced apoptosis in VSMC without involving oxygen free radicals and LPC. Aim: To examine whether oxidized low density Lipoproteins(ox-LDL)could induce apoptosis in Rabbit aortic smooth muscle cells(VSMC). Methods: Low density lipoproteins(n-LDL) Were isolated from healthy human plasma by Gradient ultracentrifugation and oxidized by CuSO_4 10μmol.L~-1. VSMC were exposed to Ox-LDL, n-LDL, or phosphate-buffer solution (PBS)as control. Morphological changes were observed under fluorescene microscope after Hoechst 33258 staining.
