摘要: 背景与目的: 利用腺嘌呤制备大鼠慢性肾功能损伤的模型。 材料与方法: 雄性SD大鼠16只,随机分为正常对照组和慢性肾功能损伤模型组,每组8只。对照组动物灌胃蒸馏水,模型组动物灌胃腺嘌呤悬液100 mg/(kg·d),实验共持续12周。实验期间监测动物的体重、血清肌酐、尿素氮水平的变化。实验结束时,检测各组大鼠肾脏的大体形态,并对肾脏组织进行HE染色病理观察以及透射电镜的检测。 结果: 模型组动物血清肌酐、尿素氮的水平明显高于对照组,而肌酐清除率明显低于对照组(P<0.05),并且随着实验时间的延长,模型组动物出现进行性的慢性肾功能损伤的改变。模型组动物肾脏的长轴长以及重量都明显高于对照组(P<0.05 ),并且出现了典型的肾脏损伤的病理学以及超微结构的改变。 结论: 用腺嘌呤100 mg/(kg·d)给予大鼠灌胃,可以制备出慢性肾功能损伤的模型。

Abstract: BACKGROUND AND AIM: To make rats' chronic renal function impairment model through adenine induce. MATERIALS AND METHODS: 16 male SD rats were randomly divided into control group and renal function impairment model group. Distilled water was administered orally to rats in the control group and adenine suspension 100 mg/(kg·d) was given to establish the model of renal function impairment. The experiment lasted 12 weeks. Time_dependent changes in serum creatinine (Cr), urea nitrogen (BUN) levels and creatinine clearance rate (Ccr) were monitored. Renal morphological changes were examined. RESULTS: Cr, BUN levels in the model group were higher and Ccr was lower significantly than control group. Renal function impairment was aggravated with extended experimental time. Pathological and ultramicrostructural changes were observed. CONCLUSION: Chronic renal function impairment model in rats could be successfully induced by adenine suspension.
