We have used electron paramagnetic resonance to investigate the time course of nitric oxide (NO) generation and its susceptibility to inhibitors of nitric oxide synthase (NOS) in ischemia-reperfusion (IR) injury to rat skeletal muscle in vivo. Significant levels of muscle nitroso-heme complexes were detected 24 h postreperfusion, but not after at 0.05, 3, and 8 h of reperfusion. The levels of muscle nitroso-heme complexes were not decreased by the NOS inhibitor N-nitro-L-arginine methyl ester as a single dose (30 mg/kg) prior to reperfusion or as multiple doses continued throughout the reperfusion (total administered, 120 mg/kg) or by the potent NOS inhibitor S-methylisothiourea (3 mg/kg). In contrast, nitroso-heme levels were reduced by the glucocorticoid dexamethasone (2.5 mg/kg). Muscle necrosis in vitro did not result in the formation of nitroso-heme complexes. The finding that reperfusion after ischemia is necessary for NO formation suggests that an inflammatory pathway is responsible for NOS-independent NO formation in IR injury to skeletal muscle.
