Objectives: The anti-inflammatory effects of O-1602 and cannabidiol(CBD), the ligands of G proteinYcoupled receptor 55 (GPR55), on experimental acute pancreatitis (AP) were investigated. Methods: Acute pancreatitis was induced in C57BL mice by intraperitoneal injection of 50 Kg/kg cerulein hourly, with a total of 6 times. Drugs (O-1602, 10 mg/kg, or CBD, 0.5 mg/kg) were given by intraperitoneal injection 2 times at 30 minutes before the first injection and immediately before the fifth cerulein injection. At 3 hours after the last injection, the blood, the lungs, and the pancreas were harvested for the pancreatic enzyme activity, myeloperoxidase activity, and pro-inflammatory cytokines measurement; and the expressions...
