中文摘要:
      雄鳗注射5~ 6 次、雌鳗注射9~ 10 次鲤脑垂体匀浆液( CPE) + 人绒毛膜促性腺激素( HCG) 能分别诱导精巢和卵巢发育成熟。在雌雄鳗鲡, 注射CPE HCG 可显著增加端脑、间脑、中脑和下丘脑 mGnRH 的含量, 而对后脑和延髓mGnRH 的影响较小; 注射CPE HCG 增加雄鳗后脑和延髓cGnRH- ò 含量, 对雌鳗脑区cGnRH- ò 则无显著影响。雌雄鳗鲡每次注射CPE HCG 后1 天, 血清促性腺激素( GtH) 急剧上 升, 10 天后逐渐下降, 但雌鳗在注射7 次后10 天血清GtH 水平仍然显著高于相应对照组。雄鳗注射CPE HCG 1~ 4 次后, 血清睾酮浓度无显著变化; 雌鳗每次注射CPE HCG 后, 血清睾酮浓度升高并一直维持在较 高水平。雌鳗血清17B- 雌二醇浓度在注射4~ 6 次期间与对照组无显著差异, 注射7 次后显著上升。
英文摘要:
      The testes and ovarian development and maturation were achieved by combinative injection of carp pituitary extraction( CPE) and human chorionic gonadotropin ( HCG) for 5- 6 times in male and 9- 10 times in female Japanese eel ( Anguilla japonica ) . The mGnRH contents in the telencephalon, disencephalon, mesencephalon and hypothalamus signif icant ly increased after injection of CPE + HCG in male and female Japanese eel, but contents in the metencephalon and myelencephalon did not change. Injection of CPE HCG also increased the cGnRH- ò contents in the metencephalon and myelencephalon in male Japanese eel, but had no effect in the female. The serum GtH levels in male and female Japanese eel increased dramatically 1 day after each injection of CPE HCG, then gradually decreased 10 days after. However the serum GtH levels in female Japanese eel remained significantly higher than the corresponding control in 10 days after 7 inject ions. The serum testosterone concentration increased after injection of CPE HCG and kept on a high level in female Japanese eel, but did not change during the time of 1- 4 injection in male Japanese eel. The serum 17B- estradiol contents were not dif ferent with the corresponding controls during 4- 6 injections in female Japanese eel, but increased after 7 injections.
