Effect of in vivo L-citrulline supplementation on TSM relaxation in hyperoxia-exposed rat pups: In vivo supplementation of rat pups with L-citrulline (200 mg/kg/day) reversed the hyperoxia-induced impairment of relaxant responses of TSM in the hyperoxic animals (p < 0.01). * Hyperoxia + L-citrulline vs. Hyperoxia; *p < 0.05; **p < 0.01 (n = 4 for each protocol of the experiments).
