Abstract/OtherAbstract:
PURPOSE: To evaluate the antioxidant effect of Propofol and N-Acetylcysteine (NAC) on intestinal ischemia/reperfusion (I/R) in rats by determining carbonyl protein level. METHODS: Forty Wistar rats were randomly assigned into the following groups: Control; Sham; I/R with Propofol; I/R with Propofol and NAC; I/R with Ketamine and Xylazine. The I/R groups underwent 60 minutes of ischemia and an equal period of reperfusion. Blood samples, collected by cardiac punction, were centrifuged for plasma obtainment. Protein carbonyl level in plasma samples was determined by immunoblotting. RESULTS: No significant difference in protein carbonyl level was found between Control and Sham groups (P>0.05). The highest reduction in protein carbonyl level (P<0.05) was obtained with the administration of Propofol and NAC (Group 4) in intestinal I/R procedure. CONCLUSION: The administration of Propofol and NAC showed the best antioxidant effect on oxidative stress in rats that underwent intestinal I/R procedure, suggesting a synergistic interaction.
