The aim of the study was to evaluate whether activation of adiponectin receptors AdipoR1 Małecka-Panas, E.; Fichna, J. and AdipoR2 with an orally active agonist AdipoRon has gastroprotective effect and to investigate AdipoRon, an Orally Active, the possible underlying mechanism. Methods: We used two well-established mouse models of Synthetic Agonist of AdipoR1 and gastric ulcer (GU) induced by oral administration of EtOH (80% solution in water) or diclofenac AdipoR2 Receptors Has (30 mg/kg, p.o.).
