摘要: 目的:研究枸杞多糖(Lycium barbarum polysaccharides,LBP)对顺铂(cis-dichlorodiamineplatinum (Ⅱ),CDDP)诱导的小鼠睾丸支持细胞TM4氧化损伤的影响,并探讨其可能的作用机制。方法:噻唑蓝法测定CDDP、LBP分别对TM4细胞生长的影响以及LBP对CDDP诱导的细胞毒性的拮抗作用。硫代巴比妥酸法测定细胞中丙二醛(malondialdehyde,MDA)含量,二硫代二硝基苯甲酸法测定谷胱甘肽(glutathione,GSH)含量,黄嘌呤氧化酶法测定超氧化物歧化酶(superoxide dismutase,SOD)活力。结果:5~100 mg/L LBP可极显著提高TM4细胞存活率(P<0.01),20~100 mg/L LBP能够极显著抑制CDDP造成的细胞毒性(P<0.01),50 mg/L的LBP保护效果最佳。50 mg/L LBP能够极显著抑制CDDP(12 mg/L)引起的MDA含量升高以及GSH含量和SOD活力降低(P<0.01)。结论:LBP能有效拮抗顺铂诱导的TM4细胞氧化损伤,其机制与LBP较强的抗氧化作用有关。

Abstract: Objective: To explore the effect of Lycium barbarum polysaccharides (LBP) on cis-dichlorodiamineplatinum (II) (CDDP)-induced oxidative damage in mouse testis sertoli cells TM4 and its possible mechanism. Methods: The survival rate of the cells was evaluated by MTT assay. Superoxide dismutase (SOD) activity was examined by xanthine oxidase method. Malondialdehyde (MDA) content was measured by thiobarbituric acid assay. Glutathione (GSH) content was determined by nitrobenzoic acid method. Results: LBP at 5–100 mg/L could significantly enhance the survival rate of TM4 cells (P < 0.01), and at 20–100 mg/L could significantly inhibit the toxic effect of CDDP on TM4 cells (P < 0.01), and the best protective effect was observed as 50 mg/L. LBP at 50 mg/L could significantly reduce intracellular MDA content, increase SOD activity and GSH levels drop compared with CDDP control group (P < 0.01). Conclusion: CDDP-induced damage in TM4 cells could be remarkably reversed by LBP, which may be related with the strong antioxidant potential of LBP.
