Effect of ADMA concentrations on arginase type I and II activity in homogenized heart tissue from controls (normoxia) and rats exposed to hypoxia. Control (open triangles), nonhypertensive (open circles), and hypertensive (black circles) rats. A Effect of ADMA concentrations on arginase type I activity. An asterisk indicates a significant difference (p < 0.01) for the control group vs. the hypertensive and nonhypertensive groups. Double asterisk indicates a significant difference (p < 0.01) for the hypertensive group vs. the nonhypertensive group. B Effect of ADMA concentrations on arginase type II activity. An asterisk indicates a significant difference (p < 0.01) for the hypertensive group vs. the control and nonhypertensive groups. Arginase activity is expressed as the percent specific activity in μmol/urea/mg/min. Data are expressed as the mean ± SE (n = 10 per group)
