Objective:To study the effects of pioglitazone on diabetic nephropathy(DN)and related mechanisms.Methods:All rats were randomized into 3 groups:normal control(NC)
diabetes mellitus control(DMC)
and diabetes treated with pioglitazone(DP).After 8 weeks of treatment
blood glucose
kidney index(KI)
microalbuminuria(MAU)
blood urea nitrogen(BUN)
and the expression of transforming growth factor β1(TGF-β1)
matrix metalloproteinase-9(MMP-9)and collagen type Ⅳ(Col-Ⅳ)in kidney were observed by immunol histochemistry.Results:KI
MAU
BUN and the expression of TGF-β1 and Col-Ⅳ in DMC group were significantly higher than other two groups(P<0.01)
but the expression of MMP-9 in DMC group was significantly lower than other two groups(P<0.01).Conclusion:pioglitazone improves DN through down-regulating the expression of TGF-β1 and up-regulating MMP-9 in diabetic rats.
