The effect of GS-E3D on α-smooth muscle actin (α-SMA) expression in glomeruli. (a) Immunohistochemical staining for α-SMA. Scale bar equals 50 μm. (b) Quantification of the α-SMA signal intensity. NOR, normal rat; DM, streptozotocin-induced diabetic rat; GS-E3D, DM treated with the indicated dose of GS-E3D. All data were expressed as mean ± the standard error of the mean (n = 8); *p < 0.05 vs. NOR group; #p < 0.05 vs. DM group
