Effect of rosiglitazone on expression and excretion of connective tissue growth factor in renal tissue and urinary of diabetic rats / 中国药理学通报

Aim To study the effect of rosiglitazone(RGZ)on expression and excretion of connective tissue growth factor(CTGF) in renal tissue and urinary of diabetic nephropathy rats.Methods Three groups of rats were studied:normal control group(n=8),STZ-induced diabetic model group(n=8),diabetes RGZ-treatment group(n=8).Urinary CTGF was measured at the 1 st,4 th,6 th and 8 th week,as well as the expressions of CTGF protein(by histochemical staining)at the 8 th week by ELISA.Results The urinary excretion rates of CTGF at 4 th、6 th、8 th weeks and the expressions of CTGF protein in renal cortex at 8th weeks significantly increased in STZ-induced model group compared with those in normal group(P
