摘　　要：为了搞清白孔雀(Pavo cristatus)肾脏的结构特征和相关活性物质的表达问题,利用生物显微技术观察了白孔雀肾脏的组织结构,用免疫组织化学方法检测了Bax蛋白在肾组织中的表达.结果显示白孔雀肾脏主要由许多肾单位、集合管和少量结缔组织组成.白孔雀肾小球毛细血管网较简单,肾小管之间排列紧密,数量较多,近端小管由单层立方上皮细胞组成,细胞顶端有刷状缘,细胞着色较深;Bax蛋白免疫反应阳性物质主要分布在近端小管上皮细胞;Bax蛋白可能与白孔雀肾脏细胞的凋亡有关.To study Pavo cristatus kidney histological structure and the expression of relevant active substances, histological structure is obvserved by light microscopy and expression of Bax protein is examined by immunohistochemical methods. The results indicate that Pavo cristatus kidney consists of many nephrons, collecting ducts and small amounts of areolar tissue. The glomerular capillary is simpler, renal tubules arrange closely and the quantity is more. The proximal tubule consists of monolayer euboidal epithelium ceils, with brush border and deeper color. Bax protein immune response positive material is mainly distributed in proximal tubule epithelium. Bax protein may be involved in the cell apoptosis of Pavo cristatus kidney and plays an important regulation role in the development of bird kidney.
