【摘要】 为探讨金钱豹(Panthera pardus)肾的组织结构和微血管构筑特点,利用生物显微技术与微血管铸型技术及扫描电镜对金钱豹肾的组织结构和肾小球微血管构筑进行了观察。结果显示,金钱豹的肾皮质与髓质厚度比为1∶(1.5~3),肾近端小管上皮为单层立方细胞,胞体较大,细胞排列紧密,分界不清楚,其腔面有刷状缘,胞质嗜酸性;远端小管无明显的刷状缘,胞质弱嗜酸性,胞核多位于中央;集合管细胞排列紧密,管腔较大,上皮细胞呈矮柱状,胞质弱嗜酸性。金钱豹的肾小球多呈球形或卵圆形,直径为99~142μm,入球小动脉管径13~15μm,出球小动脉管径9.5~11.5μm。更多还原

【Abstract】 Light microscopy,scanning electron microscopy and microvascular casting technique were used to observe the renal tissue structure and microvasculature in the Panthera pardus.The results showed that the thickness ratio between substantia corticalis and substantia medullaris of the renal was 1∶(1.5-3.0).The proximal tubular epithelium was simple cuboidal,with strong eosinophilic cytoplasm.The boundary between big and closely-arranged epithelial cells was not clear.Brush border was observed inside proximal tubule but not distal tubule.The distal tubular epithelial cells were low columnar cells with weak eosinophilic cytoplasm.The nucleus was located in the middle of the cell.The epithelial cells of collecting tubule with weak eosinophilic staining were closely arranged and the lumen of collecting tubule was big.The renal glomus was spheroidal in shape,and its diameter was 99-142 μm.The diameter of afferent glomerular arteriole was 13-15 μm.The diameter of efferent glomerular arteriole was 9.5-11.5 μm.更多还原
