The pressor (A) and cardioaccelerator (B) responses to tendon stretch before (filled bars) and after intra-arterial injection of 10 mg of tempol (open bars) in rats whose hindlimbs were freely perfused and whose femoral arteries were ligated. Baseline mean arterial pressure and heart rate values are shown within vertical bars. Means ± SE. *Significant difference (P < 0.05) between baseline and peak. †Significant difference (P < 0.05) between before and after tempol. ‡Significant difference (P < 0.05) between freely perfused and 72-h ligated.
