Task: Answer Verification
Input (English): Question: Does allopurinol increase free radical scavenging capacity during reperfusion in coronary artery bypass graft patients?
Answer: The reducing effect of allopurinol on free radical generation cannot be seen in TRAP values, obviously because the uric acid concentration of plasma decreases markedly. The positive clinical effects of allopurinol in CABG patients may arise from its direct oxygen free radical scavenging function.
Output (English): no
