Role of the angiotensin II stimulation on the vascular superoxide production.

<p>(<b>A</b>) Histogram and (<b>B</b>) digital images illustrate the presence of superoxide in dihydroethidium (DHE)-treated sections of aortic rings from SC, SRT, TC, and TRT rats under basal conditions and following stimulation with angiotensin II (Ang II: 10⁻⁴M). Three-way ANOVA analysis was performed to assess the effects of IUGR, aerobic training, Ang II treatment and of their interactions. Values are expressed as the mean ± SEM from six animals per group. <i>**P = 0.001</i> and <i>*P<0.05</i> in Tukey’s post Hoc test.
