Abstract:
Objective To study the pharmacological mechanism of glucosides of tripterygium(GTW)inducing reproductive hypofunction in female mature mice and to establish female mice model of reproductive hypofunction.Methods Female Kunming mice aged 7～ 8 weeks were randomly divided into 6 groups,including GTW groups of A,B,C,D and E(60,40,30,20,15 mg? kg-1? d-1)and normal group.Estrous cycle of five GTW groups was observed successively.To study the effect of GTW on reproductive function in different period,three batches of mice were killed when estrous cycle of some mices was prolonged,estrous cycle of all the mice was prolonged or became irregular,or estrous cycle of all the mice was totally disturbed or even disappeared.Serum E2 and P levels were measured by radioimmunoassay.Ovary and uterus index were measured by tissue-weight-assay,and tectology observation on ovary and uterus was conducted.The numbers of follicle and corpus luteum as well as thickness of endometrium and myometrium were also measured.Results The mice were killed in batches after administration for 5,7,10 weeks.After 10-week treatment,uterus index and the numbers of follicle and luteum were decreased significantly,and endometrium and myometrium also became obviously thinner in groups A,B,and C.E2 level in groups A and B was decreased.P level and ovary index of all treatment groups were not decreased after 10-week treatment.Conclusion GTW at the dosages of 60,40 and 30 mg? kg-1? d-1 can damage female mice' s reproductive function and can induce mice reproductive hypofunction with kidney deficiency after 10-week successive treatment.GTW at the dosage of 40 mg? kg-1? d-1 for 10 weeks is recommended to establish female mice model of reproductive hypofunction with kidney deficiency.
