ABSTRACT

AIM:

To explore the effects of fluctuant high blood glucose and stable high blood glucose on apoptosis and the expression of Bax and Bcl-2 in glomerular endothelial cells and renal tubular epithelial cells in diabetic rats.

METHODS:

24 SD rats were divided into 3 groups control group, stable high blood glucose group and fluctuant high blood glucose group. Diabetic rats were induced by intraperitoneal injection of STZ, and the fluctuant high blood glucose animal model was induced by intraperitoneal injection of aspart and glucose at different time points every day. Apoptosis was assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL), and immunohistochemistry was used to detect apoptosis associated gene bax and bcl-2 expression in kidney.

RESULTS:

After 4 experimental weeks, a significant increase in cell apoptosis, up-regulation of Bax protein expression in kidney tubular epithelial cell and down-regulation of Bcl-2 in glomerular endothelial cell in fluctuant high blood glucose rats were observed compared with stable high blood glucose rats.

CONCLUSION:

Fluctuant high blood glucose induces more apoptosis in renal tubular epithelial cells than that in stable high blood glucose diabetic rats.
