摘要:

目的 探究不同月龄长爪沙鼠肾脏的组织学特征。 方法 选取2、6、12月龄长爪沙鼠各10只,雌雄各半。动物安乐死后取肾脏,制作石蜡切片,HE、MASSON和PAS染色后,数字扫描观察不同月龄长爪沙鼠的肾脏组织各部分结构差异,通过图像分析软件测量肾脏组织相关数据。 结果 长爪沙鼠的肾皮质和外髓质肾小管断面中近曲小管数量较远曲小管多;随着月龄增加,肾小球密度减少,肾小球直径增加,肾小管基膜增厚,肾小管间纤维成分增多。 结论 长爪沙鼠肾脏的组织结构随着月龄增长出现差异性变化,这种变化可能与肾小球硬化、实质性细胞减少有关,具体机制有待进一步研究。

Abstract:

Objective To explore the histological characteristics of the kidney in Mongolian gerbils of different ages. Methods Ten Mongolian gerbils of 2, 6, and 12 months old (half male and half female) were selected. After euthanasia, the kidneys were taken and paraffin sections were made. After HE, MASSON and PAS staining, the structural differences of different parts of the kidney tissue in gerbils of different ages were observed by digital scanning, and the relevant data of the kidney tissue were measured by image analysis software. Results The number of proximal convoluted tubules was more than that of distal convoluted tubules in the renal cortex and outer medulla of gerbils. With age, the glomerular density decreased, the glomerular diameter increased, the basement membrane of renal tubules thickened, and the fibrous components between renal tubules increased. Conclusion The histological structure of Mongolian gerbil's kidney varies with age, which may be related to glomerulosclerosis and parenchymal cell reduction. The specific mechanism needs further study.

Key words: Mongolian gerbil, Kidney, Histological change
