Abstract:
Objective: To prove whether the cannabinoid 2 receptor agonist has an anti-inflammatory effect in the model of Ischemia/Reperfusion (I/R) injury.
Methods: Intestinal ischemia and reperfusion model was created in rats. The cannabinoid 2 receptor agonist (AM-1241) was given through the abdominal vein (iv) just before creating ischemia and reperfusion. Afterwards, evans blue was applied iv. The transition of evans blue to the tissues was seen with the naked eye. Immediately after this stage, the systemic blood circulation pool was emptied properly. Tissues were incubated at formamide for 48 hours after weighing, and measurements were made at a wavelength of 620 nm on a spectrophotometer.
Results: About 803% evans blue escape was observed in the I/R group compared to the sham control group. The difference between the I/R and the I/R+CB2 agonist is that the agonist holds proteins and reduces the transition of protein and evans blue to tissue fluid.
Conclusions: The cannabinoid 2 receptor agonist was found to inhibit the escape of protein from both the ileum and the distant organ (lung) capillaries, and thus showed antiinflammatory effect in the ileum I/R injury.
