摘要

目的探讨不同剂量的茶多酚（tea polyphenol，TP）对草甘膦（glyphosate，GLY）诱导小鼠睾丸支持细胞（sertoli细胞）氧化损伤及凋亡的拮抗作用。方法体外原代培养小鼠sertoli细胞，90 mg/L GLY培养液处理细胞形成sertoli细胞损伤模型，加入不同剂量TP（浓度分别为10、20、40、80 mg/L），形成4个拮抗组，另设由正常培养基形成的对照组；各组细胞培养24 h后，倒置显微镜下观察细胞生长情况及形态改变；四甲基偶氮唑盐（MTT）法检测细胞存活率；乳酸脱氢酶（lactate dehydrogenase

LDH）法检测细胞毒性；TUNEL法检测细胞凋亡情况；检测细胞中超氧化物歧化酶（super oxidase dimutase

SOD）活性、谷胱甘肽（glutathione

GSH）及丙二醛（malondialdehyde

MDA）含量。结果 GLY处理组细胞出现收缩变小、脱落、甚至破碎，细胞的存活率明显低于对照组（

0.05），为对照组的47.03%；细胞内LDH活性明显高于对照组；细胞凋亡指数为（37.0±4.0）%，明显高于对照组（

0.05）；细胞内SOD活性、GSH含量与对照组相比明显降低，而MDA含量明显升高（P0.05）。各拮抗组与GLY处理组相比，细胞形态有不同程度改善，尤其是拮抗组4（TP 80 mg/L）细胞生长状况明显好转，碎片明显减少；细胞的存活率、SOD活性及GSH含量明显升高（

0.05，

0.01）；细胞凋亡指数、LDH活及MDA含量明显下降（

0.05，

0.01）。结论 GLY对小鼠sertoli细胞具有诱导细胞凋亡及抑制细胞增殖，降低细胞抗氧化能力的影响，TP对GLY造成的这些损伤有一定的保护作用。

Abstract

Objective To investigate the protective effect of different doses of tea polyphenol (TP) on the mouse sertoli cells against oxidative damage and apoptosis induced by glyphosate (GLY). Methods The oxidative damage model of primarily culture

d mouse sertoli cells was established through GLY (90 mg/L) incubation for 24 h. Then the cells were treated with different doses of TP (10

40 and 80 mg/L). Meanwhile

the control cells were incubated with normal medium. After incubation for 24 h

the sertoli cells were observed for the morphological changes by inverted microscopy. Cell viability was evaluated by MTT assay. Cell cytotoxicity was measured by lactate dehydrogenase (LDH) test. Cell apoptosis was tested with TUNEL assay. The activity of super oxidase dismutase (SOD)

as well as the levels of glutathione (GSH）and malondialdehyde (MDA）were also detected. Results After the sertoli cells were treated with GLY (90 mg/L)

the cells became smaller

and more cast-off cells and cell debris were found. The cell viability was significantly lower than that in the normal control (

0.05)

only accounting for 47.03%. The LDH activity and the level of MDA were significantly higher (

0.05)

and the activity of SOD and the level of GSH were obviously lower than those of control group. Furthermore

the rate of cell apoptosis was （36.96±4.0）%

significantly higher than that of control group (

0.05). Meanwhile

when sertoli cells were treated with GLY followed by different doses of TP

the states of cells were improved

especially in those treated by 80 mg/L TP

and there were less cell debris found. TP inhibited the decrease of cell proliferation

SOD activity and GSH level (

0.05

0.01). In addition

TP also inhibited the increase of MDA level and LDH activity (

0.05

0.01). Conclusion GLY induces apoptosis

inhibits cell proliferation

and decreases anti-oxidative ability in mouse sertoli cells. While

TP plays a protective role against these damages.
