The mixed pituitary glands of Cyprinus carpio, Carassius auratus, Hypophthalmichthys molitrix and Aristichthys nobilis were extracted with ethanol. Then the crude gonadotropin was fractionated by chromatography on DEAE-cellulose and gel filtration. Biological activity as assayed by ovulation test of the loach (Misgurnus anguillicaudatus) in vivo was recognized only in the second fraction (Sephadex G-100). Effective dose of induced ovulation was 1μg/g body weight. The gonadotropin (SG-Ⅱ-2) exhibited a single...

Biological activity as assayed by ovulation test of the loach (Misgurnus anguillicaudatus) in vivo was recognized only in the second fraction (Sephadex G-100). Effective dose of induced ovulation was 1μg/g body weight. The gonadotropin (SG-Ⅱ-2) exhibited a single band on polyacrylamide gel electrophoresis. The determinable range of this gonadotropin radioimmunoassay was 0.1~16ng.Serum gonadotropin levels of carp (Cyprinus carpio) have been determined by means of radioimmunoassay through the whole reproductive process. Particularly the female exhibited a significant and higher peak during the sexual behaviour and spawning. After the spawning, the serum gonadotropin levels have a quick drop down. This investigation provided some new data for reproductive physiology of fish.

本文报道用鲤、鲢等鲤科鱼混合垂体经乙醇抽提、DEAE-纤维素层析及葡聚糖凝胶过滤来纯化促性腺激素(GTH)的方法。所得GTH初步纯化品(SG-Ⅱ-1)的产卵有效剂量为1微克/1克泥鳅体重。其最终纯化品(SG-Ⅱ-2)在聚丙烯酰胺电泳谱中呈示为一条带,可供作放射免疫测定系统中的标记抗原。GTH放射免疫测定法的检测范围为0.1~16毫微克。在鲤鱼产卵季节,用放射免疫测定血清中GTH含量的变化,表明雌雄鱼在配组后血清中GTH含量逐渐上升,特别是雌鱼,在发情产卵时出现显著的高峰,随产卵活动的停止而下降,呈现出明显的产卵前后血清中GTH含量变化规律。这为研究鱼类生殖生理提供一些新的资料。

We have attmpted the age-determination of the Loach (Misgurnus anguillicaudatus) by investigating the difference betwen circular grooves and scale grooves from the focus to the periptery of the scale.Our results show that there are noticeable markings between successive circular grooves which of translucent circule and scale grooves consist. These grooves are especially conspicuous at the boundary between the basel and the lateral area of the scale. These represent, actually, the annular formation.The season of the annulus formation has also been determined by monthly observations on the scales, and it has been revealed that the annuli are formd from the end of April until September immediately after the breeding season

本文对鳅科鱼类(泥鳅)进行研究结果表明:标志着泥鳅鳞片上的年轮是一种由数条(1—3条)环沟(circular grooves)组成的亮环(translucent circule)和从亮环上辐射出的各级鳞沟(scale grooves)为标志的。这种年轮标志的形成时期,是集中在4—9月。
