Figure 4. Effect of IMD on the cAMP content in SHR myocardium (A) and aorta (B) (n = 8). Data are expressed as mean ± SE, ^*P < 0.05 compared with SHR (A), ^*P < 0.05, ^#P < 0.01 compared with SHR, ^†P < 0.01 compared with SHR+IMD. IMD: intermedin; SHRs: spontaneously hypertensive rats group. n = 11 in each group.
