中文摘要:
      应用放射免疫测定法,对雌、雄鲤血清中促性腺激素(GTH)和17β-雌二醇(17β-E2)的含量进行周年测定。GTH的常年分泌量,雌鲤平均为8.94±5.94ng/ml(12月份含量最低,峰值在1月份);雄鲤常年平均为8.72±5.20ng/ml(10月份含量最低,峰值在11月份)。17β-E2的含量,雌鲤1-4月份较高,平均为2019.48±754.49pg/ml(全年峰值在2月份)。产卵季节后,卵巢开始退化,17β-E2含量下降。5—8月平均为454.58pg/ml,产卵前后差异性显著。这表明性腺的发育和成熟与血清中17β-E2含量变化的密切相关性以及雌二醇对GTH分泌的反馈抑制作用。
英文摘要:
      The annual changa of gonadotropin (GTH) a.nd estradiol--17 (E2) level in the serum of male and female common carp (GyPrinus curpio L) were mea-eared by radioimmunoassy(RIA). The annual average level of GTH in female carp was 8.94 a-5.94 ng/ml, with minimum 1.17+0.76ng/ml in December, and maximum 21.50+11.82 ng/ml in January. The anneal average of GTH level in male carp was 8 .72+5.20ng/mI. minimum 4 .74+2. 81 ng/ml in December and maximum 16.00+7.10 ng/ml in 1lovember. gerund E2 level in female rises from Janusry to April,the average level is 2019.48+754.49 pg/ml while the peak level is 3215.78 +206.34pg/ml in Feberay. The ovaries regressed soon aftor spawning season and E2 level significantly decreased to 454.58 pg/ml from May to August. The difference is obvious between prespa..wning rind postspawning seasons (P= 0 .001). These results indicate that the development and maturation of gonads are closely related to the change of serum E2 Ievel. The feedback effect of E2 on function of pituitary is also discussed.
