Background: During treatment, many drugs may become cause of cardiac system toxicity, cytotoxic drugs therapy cause cardiac toxicity, including 5- Fluorouracil (5- FU). It is regarded as antimetabolite which cause its toxic effects during S phase of the cell cycle and got its activation by conversion of thymidine phosphorylase into fluorodeoxyuridylate (5 fluoro 2'deoxyuridine 5'monophosphate, 5-FdUMP) which cause inhibition of thymidylate synthase, which ultimately cause prevention of synthesis of DNA.

Aim: To focus on evaluation of ethanolic artichoke extract (Cynara scolymus L) with respect to its cardio protective properties against 5-fluorouracil (5-FU) induced cardio-toxicity in rabbits by estimation of Alanine aminotransferase, creatine kinase and aspartate aminotransferase enzymes in serum.

Methods: 4 groups consisting of 8 rabbits each were made for collected 32 rabbits who were albinos. Group I: (negative control) administered dimethyl sulfoxide (DMSO) (2 ml/kg /day) orally on daily basis for duration of 10 days. Group II: (positive control) administered DMSO (2 ml/kg /day) daily via oral route for duration of 10 days and subsequently received dose of 5-FU (150 mg/kg) (single) by intraperitoneal injection, on day 8th day in connection with DMSO. Groups III: administered ethanolic artichoke extract (200 mg/kg/day) orally on daily basis for duration of 10 days. Groups IV: administered ethanolic artichoke extract (200 mg/kg/day) daily on oral basis for 10 days with subsequently single intraperitoneal dose of 5-FU (150 mg/kg) on day 8th day.

Results: Before intoxication via 5-FU, treatment of ethanolic artichoke extract note worthily reduces the increase serum levels of AST,CK & ALT enzymes due to cardio toxicity induced via 5-FU- in case of rabbits .

Conclusions: With respect to present scenario, extracts of ethanolic artichoke serve as powerful modulator in reducing or masking cardiac toxicity cause by induction of 5-FU in case of rabbits.
