In this study, real-time PCR technology was used to dectect the expression of PRL mRNA and its receptor in the reproductive tissues,which is hypothalamus-pituitary-ovary-oviduct four important tissues. The aim was to compare the difference of PRL mRNA expression in the different state of ovulatory, broody and after broody, and to analyse the relation between expression and reproduction.

本试验利用real-time PCR技术检测雪山草鸡下丘脑、垂体、卵巢、输卵管四个繁殖轴组织中PRL基因及其受体的表达量，以确定处在生产、抱窝、醒抱三个不同状态母鸡PRL基因表达的差异，并分析基因表达量的差异与生产性能的相关性。

The whole brain of the subject was axially and coronally scanned in the normal stereotactic space with a slice 1mm thick by MR system. The caudate nucleus were identified, segmented, extracted, saved and three-dimensionally reconstructed on MRI by software system developed by Research Center of Biology, Harbin University of Technology.

Methods Seventy-eight adult female PVGrats were divided into experimental group (n=60) and control group (n=18), intraneural injection technique was used to supply three kinds of NO donors with different half-life(DETA NONOate, DPTANONOate and Spermine NONOate) or saline into the rat sciatic nerve subperineurally under light microscope. At the 1th,2th,3th,7th,and 14th day of duration after sciatic nerve injection, a segment of injected sciatic nerve was taken out and embedded it in TAAB resin after tissue processing. Then it was cut into thin layers (1μm) and the histological changes were observed under high power microscope, meantime the number of degenerated axons were counted.
