Objective (s):

Gallic acid (GA), a potent anti-oxidant, plays an important role in reducing diabetic induced cardiac disorders. Therefore, the present investigation was purposed to determine the beneficial effect of GA in cardiac arrhythmias during reperfusion in diabetes induced by alloxan.

Materials and Methods:

Male Sprague-Dawley rats (200–250 g) were randomly divided into three groups (eight in each group): control (C), diabetic (D), and diabetic treated with GA (D+ G) groups. GA was administered by gavage (25 mg/kg, daily) for eight weeks. Diabetes was induced by a single intraperitoneal injection of alloxan (120 mg/kg). Ischemia-reperfusion (IR) injury was performed by ischemia and then reperfusion (30 and 120 min, respectively). The score and magnitude of arrhythmias, creatine kinase (CK-MB), and lactate dehydrogenase (LDH) of the heart, electrocardiographic, and hemodynamic parameters were …
