长爪沙鼠正常泌尿器官的组织学观察

Histological observation on the urinary organs in normal Meriones Unguieulataus

目的长爪沙鼠体内的水分调节系统很特殊,使自己能排出浓缩的尿液,节省水分,适应沙漠严酷的环境。由于肾功能的特殊性,其抗旱能力非常强。方法采用HE染色及光学显微镜技术对长爪沙鼠的肾、输尿管和膀胱等泌尿系统进行了组织学观察,结果与大鼠、小鼠相比长爪沙鼠的远端小管发达;肾髓质内层发达。结论本文的发现希望为丰富长爪沙鼠泌尿系统的组织学内容和作为实验动物化提供支持。

Objective Mongolian gerbil can make themself urine concentration for saving water and adapt to the harsh desert environment, due to their very unique moisture control system in the body.Methods Mongolian gerbil is resistant to drought on account of their special kidney. Histology of the kidney, ureter and bladder in Meriones Unguiculataus were observed by light microscopy using HE staining.Results The results showed that compared with rats and mice, the Mongolian gerbils have more developed distal tubules, and well developed inner renal medulla.Conclusions We hope that the findings of this study enrich our understanding of the histology of urinary system in Mongolian gerbils and provide support for the laboratory animalization of this animal.
