THE POSSIBLE CARDIOPROTECTIVE EFFECTS OF DIFFERENT FRACTIONS OF ARTICHOKE EXTRACTS AGAINST 5-FU INDUCED CARDIOTOXICITY IN ALBINO RATS
Objective: The present study aimed to evaluate the cardioprotective effects of ethyl acetate and methanolartichoke extracts(Cynara scolymus L.) against 5-Flurouracil (5-FU) induced cardiotoxicity in rats.
Methods: Thirty-six albino rats were divided randomly and equallyin to six groups (each group with 6 rats): I, negative control, received (2 ml/kg/d)of dimethyl sulfoxide (DMSO) orally for 30 successive d; II, positive control, received (2 ml/kg/d) of (DMSO) orally for 30 successive d, and subsequently administered a single dose of 5-FU (150 mg/kg) by intraperitoneal injection on 27thd in assossiation with DSMO; III and V, received (200 mg/kg/d) of oral methanol and ethyl acetate artichoke extracts respectivelyfor 30 successive d; V and VI, received(200 mg/kg/d) of oral methanol and ethyl acetate artichoke extracts respectively for 30 successive d,with a subsequently received single dose of 5-FU (150 mg/kg) by intraperitoneal injection on 27th d of the experiment.
Results: Prophylactic treatment of ethyl acetate and methanol artichoke extracts significantly attenuates the increased level of serum cardiac troponin T (CTn-T) and tumor necrosis factor-a(TNF-a)caused by 5-FU-induced cardiotoxicity in experimental albino rats while it increases the serum level of total antioxidant capacity (T-AOC).
Conclusion: Results of the present study suggest that methanol and ethyl acetate artichoke extracts may be an effective modulator in mitigating 5-FU induced cardiotoxicity.
