项目摘要

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.

鸟类的产卵机制可能由以下三个过程组成：开始（配对、筑巢等）、产卵的演替（孵化、排卵和产卵）和停止（繁殖）。这些进程是在内部组织的，并在一些方案下取得进展。程序是什么？本文从分子生物学的角度，对这一程序的奥秘进行了探索。主要研究内容如下：1.繁殖季节的普通鸬鹚，可能是一个连续繁殖。2.鹅卵泡的生长。3.鸡松果体与视网膜之功能分离与血浆褪黑激素之日节律。4.产卵的内分泌机制，参考性类固醇、PG和AVT。5. PG和cathecolamin灌注卵巢中的排卵。6.子宫后垂体激素受体的动态变化。7.催乳素基因在孵化母鸡中的发育表达。8.在大肠杆菌中高效表达具有生物活性的催乳素。杆菌9.日本鹌鹑卵泡颗粒细胞的增殖和分化。10.鹅繁殖周期中血浆性类固醇激素和催乳素的变化。11.日本鹌鹑周年繁殖的形成。
