Effect of fenugreek seeds on renal MMP-2 activity in diabetic rats / 吉林大学学报(医学版)

ABSTRACT

Objective To explore the effect of boiled fenugreek seeds on renal matrix metalloproteinase-2(MMP-2) activity in diabetic rats.Methods The model of diabetes was built with STZ in rats.The model rats were randomly divided into diabetes control groups (DM ) (n=10) and fenugreek seeds groups(FN) (n=10,and while normal control group (N) (n=10)rats was used.Diabetic rats were treated with fenugreek seeds for 12 weeks,the renal morphology and MMP-2 activity were observed in three groups .Results After diabetic rats were treated with fenugreek seeds for 12 weeks,optical microscopic examination indicated that the glomerular structure in N group was normal,the glomerular lesions in rats of DM groups were seriously and the pathologic changes of glomerular in rats of FN groups were alleviated significantly.Immunohistochemical results showed that the Col Ⅳ expression in glomerular ECM was increased in DM group compared with N group,and was decreased in FN group.The activity of MMP-2 was increased in FN group (1.41?0.18) compared with DM group (1.05?0.19) (P
