Responses to ANG II of isolated GA from sham-operated (A) or postischemic (B) rats. GA were subjected to increasing doses of ANG II in the presence and absence of Tempol (n = 7, 10−4 M). Data are means ± SE and are expressed as absolute change from baseline. There was no effect of Tempol on ANG II responses in sham rats. *P < 0.05 in Tempol treated vs. physiological salt solution control for AKI rats.
