摘要:

目的 本实验通过对长爪沙鼠不同年龄段肾病理表现特征的研究,为相关肾病变研究提供基础数据支持。
方法 利用 HE 染色观察长爪沙鼠不同年龄段肾病理表现,利用 CaseViewer 对肾小球、肾小囊、近曲小管进行记录、
分析;利用 CaseViewer 对肾病理评分进行分析。 结果 在 12、48 和 72 周时,可见肾小球增大,挤压肾小囊囊间隙;
肾小球外周毛细血管扩张、充血;肾小球与肾小囊黏连,并破坏附近近曲小管;肾小囊壁层增厚、分层;48、72 周时,
可见近曲小管管腔内蛋白样均质红染物质和肾小球坏死;病理评分显示,随着年龄的增长,不论是雌性还是雄性,
其肾病理程度都呈上升趋势。 其中雄性长爪沙鼠,12 与 8 周比较,72 与 48 周比较,肾小体病理评分都出现极显著
性增长(P<0. 01) ;而雌性长爪沙鼠,12 与 8 周比较,48 与 12 周比较,72 与 48 周比较,肾小体病理评分都出现极显
著性增长(P<0. 01) 。 结论 在 12 ~ 72 周时,长爪沙鼠表现出广泛的肾病理损伤,并且随着年龄的增长肾病理损伤
逐渐加重。

Abstract:

Objective This study provides reference data support for related kidney disease research by
studying the pathological characteristics of the kidneys in different age groups of long clawed gerbils.
Method Using He staining to observe the pathological manifestations of the kidneys in different age
groups of long clawed gerbils, and using CaseViewer to record and analyze the glomeruli, renal vesicles,
and proximal tubules; analyzing renal pathology scores using CaseViewer. Result At 12, 48, and 72
weeks, glomerulus enlargement can be observed, squeezing the space between renal sacs; dilation and
congestion of peripheral capillaries in the glomerulus; adhesion between glomeruli and renal vesicles, and
destruction of nearby convoluted tubules; thickening and stratification of the renal capsule wall layer. At
48 and 72 weeks, protein like homogeneous red staining and glomerular necrosis were observed in the
lumen of the proximal tubules; the pathological score showed an increasing trend with age in both females 
and males. Among them, male long clawed gerbils showed a highly significant increase in renal corpuscle
pathological score between 12 and 8 weeks, and 72 and 48 weeks (P<0. 01) , while female long clawed
gerbils showed a highly significant increase in renal corpuscle pathological score between 12 and 8 weeks,
48 and 12 weeks, and 72 and 48 weeks (P<0. 01) . Conclusion At 12-72 weeks, the renal pathology
of long clawed gerbils showed extensive renal pathological damage, and the renal pathological damage
gradually worsened with age.
