Prolactin,Growth Hormone, and Thyroid-stimulating Hormone-β, secreting by chicken anterior pituitary, are essential hormones affecting chicken laying ability, growth rate, and immunity via regulating chicken broodiness, development, and immune response.

催乳素（Prolactin，PRL）、生长激素（Growth Hormone，GH）、促甲状腺素β（Thyroid-stimulating Hormone-β，TSHβ）是家禽垂体前叶分泌的具有重要生理功能的激素，这些激素通过调控家禽就巢性的发生与维持、生长发育、免疫应答等过程来影响家禽的产蛋性能、生长性能以及免疫力。

前列腺是雄激素依赖的器官，它的胚胎发育及正常功能的维持都需要雄激素的作用。

The developmental regularity of animal gonad is determined by its genetic material anddirectly regulated by neuropeptides and hormones.

Cultured in MS medium with different concentration of calcium, explants of Luffa Cylindrica, which could not generate root in usual medium, generated roots with enhanced rates and amounts according to the concentration of supplemented calcium. Moreover, some explants show transformed root from either shoot or flower bud.

在正常Ca2+浓度下，仅激素处理不能生根的丝瓜外植体，处以不同Ca2+浓度处理时，随Ca2+浓度升高，外植体生根数明显加快并增多，且有少量植株叶腋处异化生根，在一定程度上改变了腋芽的发育方向，这说明Ca2+改变了卷须芽或花芽的发育方向，使其发育为根。

Results: 1.Empirical study: The changes of learning and memory performances and hippocampal morphology were related to ageing. Both short-term and long-term administration of excessive glucocorticoids induced the decrease of learning and memory performances and hippocampal neurodegeneration. Adrenalectomy operated during both infancy and senectitude inhibited the hippocampal structure and function.

结果：1、实验研究：动物学习记忆能力及海马的形态与增龄密切相关，短期、长期给予过量糖皮质激素可造成海马退行性改变和学习记忆功能的降低，幼年期糖皮质激素剥夺可影响动物神经发育和功能，老年期长期糖皮质激素剥夺可加重动物海马退行性病变和学习记忆能力下降。

Was also observed and evaluated ,The poison symptoms of tropically treated M.separata were observed, following a similar pattern of nerve poisoning: excitation, convulsion, paralysis, and death. The effect of acetone extract from Ferula.ferulaeoidis on the development and hatch of the eggs and survival of hatched larvae as well as ovicidal activity was observed and estimated.

蛹的生长发育有抑制作用，中毒粘虫先后表现出兴奋、痉挛、麻痹等症状，最后死亡；对黄粉虫蛹生长发育的抑制作用类似于保幼激素(Juvenile hormone analogs， JHA)活性；对棉铃虫(Heliothis armigera Hübner)卵发育、孵化及初孵幼虫存活有明显影响，表现出一定的杀卵活性。

Experts believe that: obese children accumulate excessive fat will erode the pituitary gland, so that the posterior lobe of the pituitary gland fat, discourage gonadotropin and growth hormone production, thus seriously jeopardizing the growth and development of children and adolescents, reproductive development and sexual maturation.

专家认为：肥胖儿童体内蓄积的过量脂肪会侵蚀脑垂体，使脑垂体后叶脂肪化，阻碍促性腺激素和生长激素生成，从而严重危害青少年儿童的生长发育、生殖发育和性发育成熟。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
