| 摘 要： | 目的探讨促性腺激素释放激素激动剂(GnRH-a)、拮抗剂(GnRH-ant)对环磷酰胺(CTX)诱导的大鼠卵泡凋亡的干预作用。方法36只雌性Sprague-Dawley大鼠随机分为6组,即实验对照组、CTX组、GnRH-a+生理盐水(NS)组、GnRH-a+CTX组、GnRH-ant+NS组及GnRH-ant+CTX组,每组6只,于结束用药的第1～2周内的动情间期处死,采用末端转移酶介导的缺口末端标记法(TUNEL)结合透射电镜检测卵泡的凋亡情况。结果(1)TUNEL检测晚期生长卵泡的颗粒细胞凋亡率高于早期卵泡,使用CTX组别的卵母细胞、颗粒细胞的凋亡率高于相应对照组,其差异均有显著性意义(P<0.05)。其中GnRH-a两组[(33.40±4.59)～(73.25±5.35)]的颗粒细胞凋亡率较GnRH-ant两组[(27.46±4.52)～(49.38±5.02)]明显升高,其差异有显著性意义(P<0.05);但早期卵泡卵母细胞的凋亡率在GnRH-a两组[(23.48±4.25)～(36.15±4.23)]与GnRH-ant两组[(21.47±3.81)～(34.04±5.54)]的相应组间差异无显著性意...

| Abstract: | Objective To study the effects of gonadotroph-releasing hormone (GnRH) agonist (GnRH-a) and GnRH antagonist (GnRH-ant) on cyclophosphamide (CTX)-induced follicle apoptosis in female rats. Methods Thirty-six female Sprague- Dawley rats were randomized into 6 groups, namely normal saline (NS), CTX, GnRH-a+NS, GnRH-a+CTX, GnRH-ant+NS, and GnRH-ant+CTX groups. The rats were sacrificed between the first and second week after the treatments., and the follicle apoptosis was investigated using TUNEL assay and trans... |
