Endocrinological studies on the regulatory mechanisms of egg-laying in birds.

鸟类的产蛋机制可能由以下三个过程组成；开始（配对，筑巢等），产卵的继承（抓卵，排卵和产卵）和停止（繁殖）。这些进程在内部组织起来，并在一些规划下取得进展。什么是程序？本文从分子生物学的角度出发，对程序设计的奥秘进行了探索。研究工作项目如下：1。普通鸬鹚的繁殖期，可能会连续繁殖。2. 鹅卵巢卵泡的生长。3. 松果体和视网膜功能分离与鸡血浆褪黑素昼夜节律的关系。4. 排卵的内分泌机制，参考性类固醇，PG和AVT。5. PG和儿茶酚素对灌注卵巢排卵的影响。6. 子宫受体对垂体后叶激素的动态状态。7. 蛋鸡泌乳素基因的发育表达。8. 生物活性催乳素在大肠杆菌中的高水平表达。9. 日本鹌鹑卵泡颗粒细胞的体外增殖与分化。10. 鹅年繁殖周期血浆性类固醇和催乳素。11. 日本鹌鹑年繁殖的形成。

Mechanism of egg-laying in birds might be composed of the following three processes ; Initiation (pairing, nesting and so on), Succession of egg-laying (clatch, ovulation and oviposition), and Cessation (Breeding). These processes have internaly organized and progressed under some programming. What is the programming ?The research is undertaken here to search a key of mystery of the programming, especially from a point of view of molecular biology. Items of the research works are shown as follows.1. Breeding season of the common cormorants, possibly a continuous breeder. 2. Growth of the ovarian follicles in geese. 3. Functional dissociation of the pineal glands and retina concerning diurnal rhythm of plasma melatonin in chicken. 4. Endocrine mechanism of oviposition, reference to sex steroids, PG and AVT. 5. Ovulation in the perfused ovary by PG and cathecolamin. 6. Dynamic states of the uterine receptors to posterior pituitany hormones. 7. Developmental expression of the prolactin gene in incubating hens. 8. High level expression of biological active prolactin in E. coli. 9. Proliferation and differentiation of granulosa cells of the ovarian follicles in Japanese quail, in vitro. 10. Plasma sex steroids and prolactin during annual reproductive cycles of geese. 11. Formation of annual reproduction of Japanese quail.
