观察了Ｂｒｕｃｅ运动试验对２８名年轻健康人血浆血栓素Ｂ２（ＴＸＢ２）、６－酮－前列腺素（６－Ｋ－ＰＧＦ１ａ）的影响。结果表明：Ｂｒｕｃｅ试验进行１２分钟时与试验前、试验６分钟时比较，ＴＸＢ２显著升高（ｐ＜０．０１）；试验停止后８分钟时与运动１２分钟时比较，血浆ＴＸＢ２显著下降（ｐ＜０．０１）。６－Ｋ－ＰＦ１ａ在１２分钟运动试验内变化不明显，但在试验停止后８分钟却显著升高（ｐ＜０．０１）。结论：多极运动可致血浆ＴＸＢ２、６－Ｋ－ＰＧＦ１ａ升高。这可能是运动防治高血压的机理之一。
The effects of Bruce treadmill test on plasma TXB2 and 6-K-PGF1a in 28 young healthy subjects were observed. The results showed that TXB2 was significantly increased (p <0.01) at 12 min in Bruce’s test compared with 6 min before and 6 min after test; TXB2 was significantly decreased at 8 min <0.01). 6-K-PF1a did not change significantly during the 12-minute exercise test but was significantly increased 8 minutes after the trial was stopped (p <0.01). Conclusion: Multipolar exercise can cause plasma TXB2, 6-K-PGF1a increased. This may be one of the mechanisms of exercise prevention and treatment of hypertension.
