Background: The role of nitric oxide (NO) inhibition in cerebral ischemia/reperfusion (I/R) remains uncertain; we previously reported an anti-oxidant effect of nonselective nitric oxide synthase (NOS) inhibitor N-Nitro-L-Arginine-Methylester (L-NAME) on rats subjected to transient focal cerebral I/R. The aim of this work was to the explored further potential anti-inflammatory effect of L-NAME. Materials and Methods: The study involved 30 adult male Wistar rats divided into three groups 10 rats in each: First group was sham-operated (control), I/R group of rats infused with 0.9% normal saline intraperitoneally 30 minutes prior to 30 minutes of left common carotid artery (CCA) occlusion followed by 24-hours of reperfusion and test group infused with L-NAME (15 mg/ kg per weight) intraperitoneally 15 minutes prior to the same I/R period. Neurobehavioral assessments were evaluated using six clinical tests, Western blotting was used to estimate Nuclear factor kappa B (NF-KB), Tumor necrosis factor-? (TNF-?) using ELISA and NO metabolites (nitrite and nitrate), were measured colorimetrically in both plasma and affected cerebral hemisphere. Results: L-NAME pretreated rats illustrated a significant improvement in behavioral and neurological outputs. Moreover, it significantly reduced the inflammatory biomarkers NF-KB, TNF-? and NO decreased (P ???0.001). Conclusions: L-NAME significantly improve neurological deficit and showed a potential neuroprotection through it is an antiinflammatory effect in a rat???s model of transient focal cerebral ischemia-reperfusion.
