人参皂苷保护小鼠精原细胞氧化损伤的研究

Protective effects of ginsenosides on oxidative damage in mouse spermatogonial cells

目的观察人参皂苷对活性氧引起的小鼠睾丸生殖细胞氧化损伤的保护作用。方法利用体外培养的小鼠精原细胞建立氧化应激模型,通过检测生殖细胞活性、脂质过氧化产物丙二醛(MDA)生成、超氧化物歧化酶(SOD)活性和谷胱甘肽(GSH)水平评价人参皂苷对精原细胞氧化损伤的缓解作用。结果次黄嘌呤/黄嘌呤氧化酶(HX/XO)体系产生的活性氧可引起生殖细胞活性降低、MDA的生成量增加、SOD活性和GSH水平降低,而添加人参皂苷(10mg·L-1)能恢复HX/XO引起的生殖细胞活性、SOD活性和GSH水平的下降以及MDA生成的增加。结论人参皂苷可通过抗氧化作用保护活性氧引起的小鼠精原细胞氧化损伤。

Aim To investigate the protective effects of ginsenosides （ GS） on reactive oxygen species-induced oxidative damage in mouse spermatogonial cells. Meth-ods Mouse spermatogonial cell oxidative stress model was established and the attenuating effects of ginsen-osides on germ cell oxidative damage were evaluated by determination of cell viability,malondialdehyde（ MDA） formation,superoxide dismutase （ SOD） activity and glutathione （ GSH） level. Results The exposure to hypoxanthine/xanthine oxidase （ HX/XO） induced an elevation in MDA,while a decrease in germ cell viability,SOD activity and GSH level. However,supplementation with GS （ 10 mg·L -1） restored HX/XO-induced decrease in cell viability,SOD activity and GSH level and HX/XO-induced increase in MDA formation. Conclusion GS may exert antioxidant activity to attenuate reactive oxygen species-induced oxidative damage in mouse spermatogonial cells.
