Zingiber officinale Roscoe ameliorates anticancer antibiotic doxorubicin-induced acute cardiotoxicity in rat.

Oxidative stress (OS) has been suggested in the cardiotoxicity induced by anticancer antibiotic doxorubicin (DXN). The cardioprotective effects of aqueous ethanol extract of Zingiber officinale was evaluated against DXN-induced acute cardiac damage in rat. The results of the study demonstrated that Z. officinale significantly and dose dependently protected the cardiotoxicity induced by DXN. The activities of serum glutamate oxaloacetate transaminase and serum lactate dehydrogenase activity in the DXN alone treated group of animals were significantly (p<0.01) elevated when compared to normal animals. The activities were reduced in the Z. officinale (200 and 400 mg/kg, p.o) plus DXN treated groups. The cardiac malondialdehyde was elevated in the DXN alone treated group and declined significantly in the Z. officinale (400 mg/kg) plus DXN treated group. The results concluded that aqueous ethanol extract of Z. officinale ameliorated DXN-induced cardiotoxicity. The protection can be ascribed to the free radical scavenging activity of Z. officinale. This protective effect may suggest the adjuvant role of Z. officinale against OS induced by cancer chemotherapeutants, which warrant further research.
