摘要: 目的: 比较甘西鼠尾草注射液与丹参注射液对PC12 细胞H2O2损伤的保护作用。方法: 采用细胞株培养的方法, 建立PC12 细胞H2O2损伤模型, 通过MTT 法和流式细胞分析仪检测细胞存活率和凋亡率;采用免疫细胞化学染色法检测PC12 细胞bcl-2 和bax 表达。结果: PC12 细胞经H2O2损伤后, 细胞存活率降低、凋亡率增加, 甘西鼠尾草注射液与丹参注射液处理组均可有效缓解上述改变(P <0.05) ;两药均使bcl-2 表达增加(P<0.05), bax 表达减少(P <0.05) 。结论: 甘西鼠尾草注射液与丹参注射液对PC12 细胞H2O2损伤具有明显保护作用。其机理可能与增强凋亡抑制因子bcl-2 表达、抑制凋亡促进因子bax 表达, 进而抑制细胞凋亡有关。

Abstract: AIM: To compare the influence of S. miltiorrhiza Bunge injection (SMBI) and S. przewalskii Maxim injection (SPMI) on H2O2-induced injury in PC12.METHODS: PC12 cells were cultured in vitro to compare the protective effects of SMBI and SPMI on cell injury induced by H2O2. The survival rate was measured by MTT method, and the apoptosis rate of PC12 cells was detected by flow cytometry, the protein expressions of bcl-2 and bax in PC12 cells were detected by immunocytochemistry staining method. RESULTS: When PC12 was damaged by H2O2, the rate of cell survival was degraded, and the rate of apoptosis was increased. SMBI and SPMI could alleviate the destroy effectively(P <0.05), they both could strengthen the expression of bcl-2(P <0.05) and lighten that of bax(P <0.05). CONCLUSION: The results suggested that SMBI and SPMI had comparable protective effect on H2O2-induced injury in vitro. The main effects of both injections were related to strengthening the expression of bcl-2 and lightening that of bax.
