Key result
Stimulators of NO production decreased renal oxygen consumption significantly less in spontaneously hypertensive rats than controls (e.g., bradykinin -13.9% vs -22.8%; P<0.05), which tempol reversed.
p-value: p=< 0.05
In spontaneously hypertensive rats, decreased nitric oxide availability due to enhanced superoxide production leads to impaired regulation of renal oxygen consumption, potentially contributing to renal injury.

Implicates superoxide-mediated NO impairment in hypertensive renal oxygen handling; leaves open clinical translation to human hypertension and CKD.
Adler et al. (2002) studied Hypertension. Stimulators of NO production (bradykinin, enalaprilat, amlodipine) and tempol vs. Wistar-Kyoto (WKY) rats was evaluated on Response of renal cortical oxygen consumption to stimulators of NO production (p=< 0.05). Stimulators of NO production decreased renal oxygen consumption significantly less in spontaneously hypertensive rats than controls (e.g., bradykinin -13.9% vs -22.8%; P<0.05), which tempol reversed.
