摘要
目的研究五味子乙素(SchB)对顺铂所致HK-2(肾小管上皮细胞)损伤的保护作用,并探讨其可能的机制。方法不同浓度的SchB和顺铂作用于HK-2,在倒置显微镜下观察细胞形态变化,流式细胞仪检测HK-2细胞凋亡,并检测细胞LDH(乳酸脱氢酶)、MDA(丙二醛)、LPO(脂质过氧化物)的改变,探讨SchB对HK-2保护作用的机制。结果顺铂有抑制HK-2生长、诱导其凋亡的作用IC50为18.39μmol·L-1,而20μmol·L-1的SchB能够明显减少顺铂引起的HK-2的凋亡,保护作用最强;SchB能使顺铂导致的细胞MDA、LPO、LOH升高有明显降低。结论五味子乙素能够有效的抑制顺铂引起HK-2的凋亡。机制可能是通过其抗氧化作用来抑制顺铂引起的氧化应激反应。
Aim To explore the protective role of schisandrin B （SchB）against HK-2 damage induced by Cisplatin and the probable mechanism.Methods Cultivated HK-2 was interacted by Cisplatin and SchB with different concentrations.Invert microscope showed cellular form change and Flow Cyto Meter told apopto-sis.Combined with test result on the change of L-DH, MDA and LPO,probable protective effect of SchB on HK-2 was studied and analyzed.Result Cisplatin in-hibited cells′growth and induced apoptosis.20 μmol＆amp;nbsp;· L-1 SchB significantly reduced apoptosis of Cispla-tin-induced HK-2,and offered the best protection. SchB could reduce MDA,LPO,LDH significantly in-creased by cisplatin.Conclusion SchB can be an ef-fective inhibition agent of Cisplatin-induced renal tubu-lar epithelial cell apoptosis （HK-2 ）.The mechanism can be the inhibition of Cisplatin-induced oxidative stress by antioxidant effect.
