Figure 2: Comparison of glomerular afferent and efferent arteriole diameters before and after acute drug administration in diabetic rats. Typical images of glomeruli in the Cont group (A) recorded using a CCDV microscope. Glo, glomerulus; Af, afferent artery; Ef, efferent artery. Scale bar=50 μm. (B) Percent changes in afferent and efferent arteriolar diameters following acute drug treatment compared with the non-diabetic control group. N=4 rats/ group. *p<0.05 vs. Cont. †p<0.05 vs. DM.
