摘 要:目的:研究不同药性的中药,属凉性的西洋参水提物(WEAG)和属温性的红参水提物(WERG)对四氢吡啶离子(MPP+)诱导神经母细胞瘤(SH-SY5Y)细胞凋亡的影响。方法:将细胞分4组,对照组为常规加入完全培养基,模型组为加入0.5mmolMPP+,西洋参组和红参组同时加入0.5mmolMPP+和不同浓度的WEAG及WERG。给予WEAG和WERG进行干预。应用Hoechst33258染色观察细胞形态变化,MTT比色法检测细胞活力,流式细胞仪检测细胞凋亡率。结果:与模型组比较,WEAG和WERG能显著改善模型组SH-SY5Y细胞的凋亡特性,显著升高其吸光度值,降低凋亡率,且WERG保护作用强于WEAG。结论:WEAG和WERG均对MPP+诱导的SH-SY5Y细胞凋亡具有不同程度的保护作用,而温性中药抗凋亡作用更强,药性不同,其抗凋亡作用亦不同。OBJECTIVE: To investigate the effects of water extract of Panax quinque foliurn (WEAG, of cool property) and Panax ginseng(WERG, of warm property) on MPP^+ - induced apoptosis of SH - SY5Y cells. METHODS: SH - SY5Y cells were divided into 4 groups: the control group was cultured in complete medium, model group was cultured with 0.5 mmol MPP^+; Panax quinque foliurn group was treated with 0.5 mmol MPP^+ plusdifferent concentration of WEAG, and Panax ginseng group was treated with 0.5 mmol MPP^+ and different concentration of WERG concomitantly. WEAG and WERG were added for intervention.the morphology of SH- SY5Y cells was observed by Hoechst33258 staining and the apoptotic rate was detected by FCM; the cell survival rate was measured by MTT chromatometry .RESULTS: Compared with model group, WEAG and WERG markedly reversed the apoptotic characteristics of SH- SY5Y cells, markedly up - regulated MTT value and lowered the apoptotic rate, with WERG showing more potent efficacy than WEAG doing. CONCLUSION: Water extracts of both Panax quinque foliurn (cool) and Panax ginseng(warm) pose protective effects of different degree against MPP^+- induced apoptosis of SH-SYSY cells, with the Chinese materia medica of warm property showing more potent action against apoptosis. Chinese materia medicas of different drug property have different anti - apoptotic action.
