| 摘 要： | 目的]探讨大通牦牛的皮肤发育规律。方法]采用组织学方法对4个年龄段（1日龄、30日龄、180日龄和成年牦牛）大通牦牛的皮肤组织结构进行研究。结果]4个年龄段大通牦牛的皮肤均表现为表皮薄、真皮特厚的特点,且真皮层内毛细血管较少,表皮层内含大量色素细胞;4个年龄段大通牦牛的全皮厚均表现为出生后至30日龄逐渐变厚、至180日龄时又变薄、至成年时又变厚的一种变化趋势。结论]为深入了解大通牦牛皮肤适应高原恶劣环境的组织结构特点提供了理论依据。

| Abstract: | Objective] This study was to explore the skin development law of Datong Yak.Method]Taking Datong yaks at four various growth stages（1 day old,30 days old,180 days old and adult）as experimental materials,we studied histological structure of Datong yak skin by employing the histological methods.Results]The skins of Datong yak at four various growth stages all showed the characteristics of thinner epidermis and thicker hypodermis,and of less capillary vessels in hypodermis and more pigment cells in epidermis.Datong yak at four various growth stages all showed a fluctuating trend in entire skin thickness,in detail thickening from 1 day old to 30 days old,then thinning to 180 days old,again thickening to adult.Conclusion]The results provided theoretical basis for further understanding the structural characteristics of Datong yak to adapt to the abominable plateau environment. |
