Figure 1B: Cumulative concentration-response curves for KCl in aortic preparations after 1 month in the presence (B) of endothelium. Contractile responses are expressed as grams of tension per square millimeter of cross-sectional area (mm2). Data are shown as means � SEM. *P < 0.05 (as compared to VD) (VC, EC, VD, and ED represent vehicle-treated control, extract-treated control, vehicletreated diabetic, and extract-treated diabetic rats, respectively)
