本文研究了进食试餐和＂假吃＂引起的人体胆囊收缩运动，以及前列腺素（ＰＧ）合成酶（环加氧酶）抑制剂消炎痛对它们的影响。结果表明，试餐后１ｈ和假吃５ｍｉｎ均引起胆囊明显缩小，而预先（９０ｍｉｎ）口服７５ｍｇ的消炎痛，试餐及假吃引起的胆囊收缩明显减小，表明内源性ＰＧ参与进食及假吃引起的胆囊收缩。 This article examines the human gallbladder contraction movement caused by eating a test meal and “fake eating,” and the effects of indomethacin, a prostaglandin (PG) synthase (cyclooxygenase) inhibitor, on them. The results showed that the gallbladder was significantly reduced at 1 h and 5 min after the meal, while the 75 mg of indomethacin administered orally (90 min) significantly reduced the gallbladder contraction induced by the test meal and the sham diet, indicating that endogenous PG participates in eating and drinking Gallbladder contraction caused by eating.
