我们进行了一项双盲随机研究,以探讨内源性三尖杉酯碱在肾上腺素诱导的人胃电机械活动的变化中的作用。静脉注射药理学剂量的肾上腺素(222 ng/kg/min)导致12名健康受试者中的8名出现胃节律紊乱。吲哚美辛治疗后,肾上腺素诱导的胃节律紊乱的发生率降低至12例健康受试者中的4例,这与安慰剂组中观察到的胃节律紊乱的发生率相似。然而,差异无统计学显著性(P= 0.2)。肾上腺素还显著抑制胃窦收缩的幅度和频率。吲哚美辛治疗部分逆转了胃窦收缩幅度的降低,但没有逆转频率的降低。这些结果表明,内源性的Ephylandins可能,在一定程度上,调节人类胃窦收缩的幅度,然而,Ephylandins在肾上腺素诱导的胃节律障碍在人类中的作用仍然不确定。
We conducted a double-blind randomized study to investigate the role of endogenous prostaglandins in epinephrine-induced changes in human gastric electromechanical activity. Intravenous administration of a pharmacologic dosage of epinephrine (222 ng/kg per min) caused gastric dysrhythmia in 8 of 12 healthy subjects. After indomethacin treatment, the incidence of epinephrine-induced gastric dysrhythmia was reduced to 4 of 12 healthy subjects, which is similar to the incidence of gastric dysrhythmia noted in the placebo group. The difference, however, was not statistically significant (P= 0.2). Epinephrine also substantially inhibited both the amplitude and the frequency of antral contractions. Indomethacin treatment partially reversed the reduction in the amplitude but not the frequency of antral contractions. These results suggest that endogenous prostaglandins may, in part, regulate the amplitude of human antral contractions; however, the role of prostaglandins in epinephrine-induced gastric dysrhythmia in humans remains uncertain.
