Antioxidant properties of glutamine and its role in VEGF-Akt pathways in portal hypertension gastropathy

Figure 1 Effect of partial portal vein ligation and glutamine administration on gastric oxidative stress, nitric oxide production, antioxidant enzyme activities. A: Effect of partial portal vein ligation and glutamine administration on gastric oxidative stress; B: Effect of partial portal vein ligation and glutamine administration on gastric nitric oxide production; C: Effect of partial portal vein ligation and glutamine administration on gastric antioxidant enzyme activities: (1) SOD activity; and (2) GSH activity. TBARS concentration. Values are the mean ± SE for 14 rats. ^aP < 0.05 vs the sham-operated group. PPVL: Partial portal vein ligation; G: Glutamine; SOD: Superoxide dismutase; GSH: Glutathione; TBARS: Thiobarbituric acid reactive substances; SO: Sham-operated.
