Histological Characteristics of Adult Yak Epididymis in Different Breeding Seasons
摘要
Abstract
To compare the histological changes of the adult yak’s epididymis in different breeding seasons,six adult yak testis in breeding season and nine adult yak testis in breeding interval were collected for structure investigation by HE staining,Masson’s and Gomori ’s histochemistry methods,and IPP (Image-Pro Plus)statistics method was used to quantitative statistics.The re-sults showed that comparing with the adult yak in the breeding interval,the epididymis ducts of adult yak in the breeding season were covered with the columnar ciliated epithelium.The collagen and reticular fiber in cauda epididymis were obviously more abundant than caput and corpus epi-didymitis.And the thickness of columnar epithelium cells in caput and corpus epididymitis,the length of the cilia in caput,and also the internal and external lumen diameter of caput and corpus epididymitis were all significantly increased in the breeding season (P <0.05 ),but the external lumen diameter of the cauda epididymis had no significant differences (P >0.05).In conclusion, the research showed that the distribution of collagen and reticular fiber in adult yak’s epididymis interstitial were similar,and they were more rich in cauda epididymis,which might relate to the capacity and the sperm transport;The changes of the epithelial thickness,the length of cilia,the internal and external lumen diameter were close related to the different breeding seasons,and it might be a common phenomenon in plateau mammals that the enlargement and reduction of the epididymal duct in different breeding seasons.关键词
