摘要:

旨在研究牦牛脾发育过程中组织结构的变化,进一步探讨牦牛脾的结构特点。运用解剖组织学方法对初生牦牛及成年牦牛脾组织结构进行观察。结果显示,初生牦牛脾组织结构发育不全,白髓无脾小结,仅观察到动脉周围淋巴鞘(PALS)。成年牦牛脾组织结构发育完整,白髓包括脾小结和动脉周围淋巴鞘。脾小结呈现3种不同的形态,单位面积内脾小结个数Ns=0.145 个•mm-2,成年牦牛脾白髓相对面积Aw=8.82%;初生牦牛脾白髓相对面积Aw=5.46%。2个年龄段牦牛脾白髓相对面积差异极显著(P<0.01)。电镜观察显示牦牛脾无完整窦壁结构。本研究首次报道了牦牛脾小结的发育特点,牦牛脾为无窦型脾,成年牦牛白髓面积大于初生牦牛。

Abstract:

The developmental changes of structural characteristics of yak spleen were studied,in order to give a further discussion about the yak spleen.The anatomical,histological and stereology statistics methods were used to observe the histological structure of spleens in newborn and adult yak.The results showed that the structure of newborn yak spleen was hypoplasia,white pulp had no splenic nodule,only the periarteral lymphatic sheath (PALS) in spleen being observed.While the structure of adult yak spleen was completely developed,white pulp was composed of splenic nodule and periarteral lymphatic sheath (PALS).The splenic nodule appeared as three different shapes,the splenic nodule number per unit area was Ns=0.145•mm-2.White pulp relative area of newborn yak spleen was Aw=5.46%,while adult yak spleen was Aw= 8.82%,the differences between the two groups were extremely significant (P<0.01).The sinus wall structures were not observed through the electron microscopic.This study reported the developmental characteristics of yak spleens firstly,the yak spleen was nonsinusal.White pulp area in adult yak was greater than the newborn.
