Abstract:

Objective: To evaluate the cardio-protective effect of Ginkgo Biloba (GB) on doxorubicin induced-cardiotoxicity.

Methods: The experimental study was conducted at the College of Medicine, Mustansiriya University, Baghdad, Iraq, from January to March, 2016, and comprised thirty Wistar Sprague male rats aged 3-4 months and weighing 200-400 g. The rats were divided into three equal groups (n=10); GroupІ (control): rats were treated with distilled water, Group ІІ (doxorubicin): rats were treated with distilled water and doxorubicin 20 mg/kg, and Group ІІІ (GB): rats were treated with GB and doxorubicin 20mg/kg. Serum malondialdehyde (MDA), glutathione reductase (GSH), lipid peroxidise (LPO),tumour necrosis factor-alpha (TNF-α), cardiac troponin (cTnI), brain natriuretic peptide (BNP) and caspase-3 (Cas-3) were measured using enzyme-linked immunosorbent assay kits. SPSS 20 was used to compare the effect GB with doxorubicin on the biomarkers of doxorubicin induced-cardiotoxicity.

Results: Doxorubicin led to cardiotoxicity through elevation of cTnI, BNP, Cas-3 and LPO compared with controls (p<0.01).Also, MDA and TNF-α were elevated while; GSH was decreased significantly (p<0.01) compared with controls. Co-administration of GB with doxorubicin led to significant reduction in cTnI, Cas-3 sera levels with elevation in GSH serum level significantly (p<0.05). The effect of GB on BNP, LPO, MDA and TNF-α was insignificant (p>0.05) compared with the doxorubicin.

Conclusions: GB has significant cardio-protective effect through attenuation of oxidative stress during doxorubicin induced-cardiotoxicity in rats.
