Abstract

Among all the mammalian pituitary hormones, luteinizing hormone (LH) was the most potent in vitro inducer of oocyte maturation in L. rohita, C. mrigala, C. catla and C. carpio. It induced significant germinal vesicle breakdown (GVBD) at concentrations of 10, 1, 0.1 and 0.01 micrograms/ml. At the highest concentration used, LH induced 77.9 +/- 5.9, 73.8 +/- 4.6, 50.3 +/- 2.8 and 40.8 +/- 1.4% GVBD in oocytes of L. rohita, C. mrigala, C. catla and C. carpio, respectively. Among other hormones, follicle stimulating hormone (FSH) induced only a marginally significant GVBD (13.2 +/- 0.8%) in the oocytes of C. carpio, but not in other three species. Thyroid stimulating hormone (TSH), growth hormone (GH) and prolactin (PRL) had no effect on GVBD.

摘要

在所有哺乳动物垂体激素中，促黄体生成素（LH）是体外诱导印度鯽、麦瑞加拉鲮、印度野鲮和鲤鱼卵母细胞成熟的最有效激素。在浓度为10、1、0.1和0.01微克/毫升时，它能诱导显著的生发泡破裂（GVBD）。在所使用的最高浓度下，LH分别在印度鯽、麦瑞加拉鲮、印度野鲮和鲤鱼的卵母细胞中诱导了77.9±5.9%、73.8±4.6%、50.3±2.8%和40.8±1.4%的GVBD。在其他激素中，促卵泡激素（FSH）仅在鲤鱼卵母细胞中诱导了轻微显著的GVBD（13.2±0.8%），但在其他三个物种中未诱导。促甲状腺激素（TSH）、生长激素（GH）和催乳素（PRL）对GVBD没有影响。
