中文摘要：

本研究以不同发育阶段的雄性雏鸵鸟（Struthio camelus）为试验动物,在其饮水中添加不同剂量的硼,采用放射免疫分析法（radioimmunoassay,RIA）检测不同硼水平和不同发育阶段雏鸵鸟血清中卵泡刺激素（follicle stimulating hormone,FSH）、黄体生成素（luteinizing hormone,LH）、睾酮（testosterone,T）、雌二醇（estradiol,E2）的含量,旨在探明硼对雏鸵鸟血清性激素水平的影响。研究结果表明,雄性雏鸵鸟血清FSH和E2含量均随硼添加量的增加而增加;LH和T的含量随硼添加量的变化表现出一定的相关性,且均表现为低硼水平其含量升高,中硼和高硼水平其含量降低;LH和T的含量随年龄增大而增加,E2逐渐减小,而FSH则先升高后下降。该结果提示,硼对鸵鸟内分泌与生殖具有一定的调节作用,且年龄对雏鸵鸟血清性激素水平有一定影响。

英文摘要：

Taking different age of male young struthio camelus as its experimental animal, this research added different do ses of boron into its drinking water, and adopted the method of radioimmunoassay （RIA） to detect the contents of follicle stim ulating hormone （FSH）, luteinizing hormone （LH）, testosterone （T）, and estradiol （Ez） in serum under different levels of boron and at different age. It aimed to explore the influence of boron on the levels of serum hormone of young struthio came lus. The results indicated that the contents of FSH and E2 of male struthio camelus increase with that of boron, with the change of the boron doses the contents of LH and T showed a certain relevancy,their contents rised with low boron while re duced with medium and high boron, the contents of LH and T rised with the age increasing and E2 gradually reducing, while FSH firstly increased then reduced. The results demonstrated that boron had a certain function in regulating Struthio camelus＇ endocrine and reproduction, and age exerted certain influence on Struthio camelus＇ serum sex hormone.
