Figure 4 Plasma NO Levels

Plasma nitric oxide (NO) levels in rats: (A) NO₃, (B) NO₂, and (C) NO_x (NO₃+NO₂). Blood samples were drawn by cardiac puncture at the end of reperfusion, and plasma NO₃ and NO₂ levels were evaluated. The NO₃, NO₂, and NO_x levels (%) are shown relative to the control. The control sample was defined as 100% NO production, and the percent increase or decrease in NO production relative to the control was calculated for each sample. The asterisk *p < 0.05 for the rHDL group versus the rHDL+L-NAME group. **p < 0.01 for the rHDL group versus the control group. ***p < 0.05 for the rHDL group versus the control group. Abbreviations as in Figure 1.
