摘要
There are conflicting reports about the expression of cyclooxygenase (COX)-2 in human platelets. The present study describes a flow cytometric method for the measurement of platelet COX. Both COX-1 and COX-2 were shown to be expressed in platelets from patients undergoing a coronary artery bypass graft. There was a significant increase in COX-2 expression at day 5 as compared with pre-surgery values (mean fluorescence 12.31 +/- 0.88 versus 9.15 +/- 0.88; means +/- SEM, n = 7, P < 0.05), whereas COX-1 levels did not change (13.45 +/- 1.11 versus 12.38 +/- 1.41; n = 7, P > 0.05).
