Abstract
  1. The effects of the cyclo-oxygenase inhibitors, indomethacin (1.3 microM) and mefenamic acid (10 microM), were investigated on the naloxone-precipitated withdrawal contracture of the morphine-dependent guinea-pig ileum in vitro. 2. Both indomethacin and mefenamic acid prevented expression of the withdrawal contracture on naloxone challenge. 3. The effects of indomethacin were reversed by the concurrent application of a low dose of prostaglandin E1 (10 nM). 4. It was concluded that prostaglandins probably play a role in the expression of morphine withdrawal in this model.
摘要
  1. 研究了环氧化酶抑制剂吲哚美辛(1.3微摩尔)和甲芬那酸(10微摩尔)对纳洛酮诱发的吗啡依赖豚鼠离体回肠戒断挛缩的影响。2. 吲哚美辛和甲芬那酸均可阻止纳洛酮激发时戒断挛缩的表现。3. 同时应用低剂量前列腺素E1(10纳摩尔)可逆转吲哚美辛的作用。4. 得出结论:在该模型中,前列腺素可能在吗啡戒断表现中起作用。
