The effects of rutin and quercetin on ECG parameters in 5-FU-induced cardiotoxicity rat model

5‐fluorouracil (5-FU), a pyrimidine analogue anticarcinogenic agent, is widely used in the solid tumors treatment. Use of the 5-FU causes cardiotoxicity. Our aim in this study investigations effects of Quercetin and Rutin on ECG parameters in the 5-FU-induced cardiotoxicity in rats. In the present study used male rats. Rats were divided randomly to eight group. The control group was given intragastric corn oil for 14 days. The 5-FU group rats were given ig corn oil for 14 days and injected intraperitoneal the single dose of 5-FU(50 mg/kg) on the eleventh day. The Q50+5-FU and Q100+5-FU groups were given ig 50 mg/kg and 100 mg/kg Q for 14 days, respectively and these groups were injected single dose of 5-FU(50 mg/kg) on the 11th days of Q application. The group Q100 was Q(100 mg/kg-ig) for 14 days. The Rutin50+5-FU and Rutin100+5-FU groups were injected ig 50 mg/kg and 100 mg/kg of the Rutin for 14 days, respectively. These groups were injected single dose of 5-FU(50 mg/kg) in the 11th days of Rutin application. The Rutin 100 group was given Rutin(100 mg/kg-ig) for 14 days. In the end of experimental application recorded to ECGs of the rats. 5-FU administration rats were observed that it was caused sinus tachycardia and ST elevation. Also, in the 5-FU group QRS segment was shorter and the duration and amplitude of the P was different from other groups. In both doses of Q and Rutin were prevented these changes and our findings were seen the consistent with the literature.
