Fig. 6

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