Protective Effect of Periplaneta Americana Extract CII-3 against Arrhythmia in Rats

Objective: To explore the protective effect and mechanism of CII-3 extracted from Periplaneta americana against
arrhythmia induced by aconitine in rats. Methods: Arrhythmia in rat was induced by aconitine with femoral vein injection, with different doses of CII-3 treatment, the incidence rates of ventricular premature beats(VP), ventricular tachycardia(VT), ventricular fibrillation (VF)and cardiac arrest (CA)were recorded, and the arrhythmia score, activity of CK and LDH were detected. Results:The amount of aconitine in inducing VP, VT, VF and CA was increased after CII-3 treatment, which showed decreased incidences of VT, VF, CA and the arrhythmia score, as well as the the activity of CK (P<0.05). However, there was no influence of CII-3 on the activity of LDH. Conclusion: The data demonstrated that there was remarkable protective effect of CII-3 against arrhythmia induced by aconitine in rats.
