Effect of Yishen capsule on the expression of podocalyxin in the kidney of STZ induced diabetic rats. The regulation of podocalyxin in the glomerulus is displayed in panel A (podocalyxin fluorescence) and panel B (RT-PCR). Both Yishen capsule and benazepril were able to restore expression of podocalyxin in the glomerulus of rats with STZ injection. However, podocalyxin levels in Yishen capsule and/or benazepril treatment groups are still lower than that of normal group. Data are expressed as mean ± SD from eight rats. * indicates p < 0.05 as compared to normal control group.
