AGT and Ventricular hypertrophy: Ang II treatment induced a remarkable ventricular hypertrophy indicated by substantially increased (HW/TL) ratios (7.7±0.3 mg/mm in control group (n = 6) vs. 15.6±0.2 mg/mm in Ang II group, p<0.01, n = 6) and mean cross-sectional areas (228±10 μm2 in control group (n = 6) vs. 376±11 μm2 in Ang II group (n = 6), p<0.05 Figure 2.B,C).
