摘要 目的观察阿维菌素对大鼠卵巢颗粒细胞分泌功能的影响。方法体外实验采用终浓度为16.16、4.04、1.01μg/ml剂量的阿维菌素对大鼠卵巢颗粒细胞染毒24h,测定培养液中细胞活性和雌二醇、孕酮含量;动物实验采用5.0、1.0、0.2mg/kg剂量的阿维菌素对大鼠灌胃染毒10d,取卵巢颗粒细胞,测定雌二醇和孕酮分泌水平。结果体外染毒条件下,3个剂量组的雌二醇、孕酮含量均较对照组降低,其中高、中剂量组[雌二醇:(17.14±4.84)、(16.89±3.33)ng/ml,孕酮:(10.62±2.51)、(15.42±2.40)ng/ml]与阴性对照组[雌二醇、孕酮分别为(60.49±9.07)、(24.36±2.30)ng/ml]比较,差异均有统计学意义(P<0.01),相关分析结果表明,雌二醇、孕酮含量与阿维菌素有剂量-效应关系,r值分别为0.808,-0.871,差异均有统计学意义(P<0.01)。采用动物实验方式,高剂量组雌二醇含量[(41.16±12.99)ng/ml]低于阴性对照组[(94.97±37.88)ng/ml],差异有统计学意义(P<0.05),高、中剂量组孕酮含量低于对照组,差异亦有统计学意义(P<0.01)。结论阿维菌素对大鼠卵巢颗粒细胞的分泌功能有抑制作用。
