Effect of L-citrulline (L-Cit, 300, 600, 900 mg/kg, i.g.) on iNOS expression in the gastric mucosa after ischemia-reperfusion (I/R) injury in rats. (A) Inducible nitric oxide synthase (iNOS) protein levels in the gastric mucosal homogenate as visualized by immunoblotting with antibodies against iNOS. (B) Densitometric analysis after normalization with β-actin. Data represents mean ± S.E.M., n=4 *P< 0.001 compared with the sham group; #P< 0.01, ##P< 0.001 compared with the ischemia-reperfusion (I/R) group
