摘要
本实验用0.8％CdCl_2生理盐水按1 mgCd/kg体重,隔日1次皮下注射3个月,建立兔中毒模型。测定了血尿素氮、肌酐含量及肾皮质的Na^+/K^+-ATPase,Ca^(2+)-ATPase,γ-GT的活性。结果表明,在肾中毒早期,尿素氮、肌酐无明显变化,几种酶活性明显下降,P值分别<0.05及<0.001。提示,这些酶活性下降,可能是镉中毒所致肾功能紊乱和病理改变的启动环节之一和进一步导致肾衰的机理之一。
Rabbits were intoxicated with hypodermic injection of 0.8% CdCl2 in normal saline every other day for 3 months,and the blood level of urea nitrogen (BUN) and creatinine (Cr) and the activities of Na/K-ATpase,Ca-ATPase,and γ-GT in the renal cortex were determined.It was found that there were no remarkable changes of BUN and Cr level but significant reduction of the activities of the 3 enzymes.It is believed that the reduction of the enzyme activities is one of the factors to initiate the functional disturbances and morphological damages of the kidneys and plays an important role in the mechanism of renal failure if it is not promptly corrected.
