摘要: 目的: 研究氯苄四氢小檗碱对过氧化氢(H2O2)引起无血清培养的小牛主动脉血管内皮细胞的凋亡、增殖、坏死的影响。方法: 通过体外细胞培养, 以噻唑兰(MTT) 法测定细胞存活率;用流式细胞术检测细胞DNA 含量及凋亡细胞百分率、增殖率;DNA 琼脂糖凝胶电泳法观察细胞凋亡过程中DNA 断裂程度。结果: H2O2 诱导无血清培养的内皮细胞凋亡, 氯苄四氢小檗碱可显著降低内皮肌细胞中凋亡细胞百分率, 并抑制其增殖, 也减少凋亡细胞DNA 断裂, 同时也减少其引起的平滑肌细胞坏死。结论: 氯苄四氢小檗碱可对抗H2O2 引起的无血清培养的血管平滑肌细胞凋亡、增殖及坏死。

Abstract: AIM: To examine the inhibition of chlorobenzyl-tetrahydroberberine (BTHB) on the H2O2-induced apoptosis and proliferation of endothelial cells(ECs) in the serum deprivation medium.METHODS: The DNA content and percentage of apoptosis were measured by flow cytometry;the DNA fragmentation was analyzed by agarose gel electrophorsis;the viability percentage of cells was measured using MTT assay.RESULTS: The apoptosis and proliferation of ECs occuredin serum-free medium (18 h) containing H2O2.When the ECs had been treated with BTHB, the percentage of ECs apoptosis and proliferation was markedly decreased, and the degraded fragments of DNA obviously decreased.BTHB (10-5, 10-6, 10-7, 10-8mol·L-1) could partly protect cells from necrosis induced by H2O2.CONCLUSION: BTHB can prevent ECs from apoptosis, proliferation and necrosis induced by H2O2 in free-serum medium.
