Objective:to investigate the time behavior of plasma TXB2 and 6-Keto-PGF1α levels in rats undergoing cerebral ischemia reperfusion. Methods:Forty-five Sprague-Dawley(SD) rats were randomly divided into the control group,the model groups,and sham operation groups. 1,3,5,and 7 days after operation,the contents of plasma thromboxane B2(TXB2) and 6-keto-PGF1α content were detected by radioimmunoassay method. Results:Compared to those in the control and sham operation groups,plasma TXB2 level and TXB2/6-keto-PGF1α ratio markedly increased(...
