ABSTRACT
Objective To detecte the changes of nephrin in adriamycin nephropathy rats, study the effects of mycophenolate mofetil on minimal change nephrotic syndrome, investigate its possible mechanism. Methods 18 SD rats were randomly divided into three groups: control group(CG, n=6), adriamycin model group(AG, n=6), MMF treated group(TG, n=6). Rats in MG and TG were given adriamycin 7.5mg/kg through vena caudalis. At the same time, an equal volume of normal saline was given to the rats in CG by the same method. The rats in TG received MMF 20mg/(kg?d) by daily gastric gavage from the second day. Urinary protein excretion of each rat were measured at the day before adriamycin injection,and the 14th day and the 28th day after adriamycin injection. Six rats of each group were killed at the 28th day. Serum urea nitrogen, creatinine, cholesterol, triglyceride and albumin were measured at the end of the study. Immunohistochemistry and western blot were used to examine the expression of nephrin. Results The urinary protein excretion of AG at 28th day was the highest. Serum albumin decreased markedly at the 14th day(p
