The aim of this study was to reveal whether therapeutic value of cannabinoid 2 (CB2) receptor activity in the intestinal I/R, via to the exogenous administration of CB2 agonist (AM-1241). Intestinal I/R injury were performed through 30-min ischemia and 150-min reperfusion of mesenteric artery in Wistar rats. The pre-administered doses of 0.1, 1, and 5 mg/kg of CB2 agonist were studied to inhibit inflammation of intestinal I/R injury including ileum smooth muscle contractility, polymorphonuclear cell migration, oxidant/antioxidant defense system, and provocative cytokines. Pre-administration with CB2 receptor agonist ensured to consider improving the disrupted contractile responses in ileum smooth muscle along with decreased the formation of MDA that production of lipid peroxidation, reversed the depleted glutathione, inhibited the expression of TNF-alpha and of IL-1 beta in the intestinal I/R of rats. Taken together results of this research, the agonistic activity of CB2 receptor for healing of intestinal I/R injury is ensuring associated with anti-inflammatory mechanisms such as the inhibiting of migration of inflammatory polymorphonuclear cells that origin of acute and initial responses of inflammation, the inhibiting of production of provocative and pro-inflammatory cytokines like TNF-alpha and IL-1 beta, the rebalancing of oxidant/antioxidant redox system disrupted in injury of reperfusion period and the supporting of physiologic defensive systems in endothelial and inducible inflammatory cells.Duzce UniversityDuzce University [2012.04.
