Figure 3: The influence of captopril (cap) treatment (40 and 80 mg/kg) on the left ventricular wall thickness (LVWT) of diabetic and non-diabetic Wistar Kyoto (WKY) rats. Diabetic WKY rats showed a significant (P<0.01) increase in LVWT. The cap- treated (40 and 80 mg/kg) diabetic WKY rats produced a significant (p<0.01) reduction in the LVWT compared to the control (cont) diabetic WKY rats. Each column (n=7) represents mean± SEM.
