  Dexamethasone prophylaxis of nausea and vomiting after epidural morphine for post-Cesarean analgesia

  摘要：

  Purpose: To determine the minimum effective dose of dexamethasone in preventing nausea and vomiting associated with epidural morphine for post-Cesarean analgesia.Method: One hundred and eighty parturients (n=45 in each of four groups) requiring epidural morphine for post Cesarean analgesia were enrolled in this randomized, double blinded, placebo-controlled study. At the end of surgery, parturients received either dexamethasone, at doses of 10 mg, 5 mg, 2.5 mg, or saline iv. Three milligrams epidural morphine were given to all parturients for postoperative analgesia, The incidence of PONV and side effects were estimated for 24 hr after delivery by blinded, trained nurse anesthetists.Results: Parturients who received dexamethasone, either 10 mg or 5 mg were different from those who received saline alone in the following parameters: the total incidence of nausea and vomiting, incidence of > 4 vomiting episodes, number the of parturients requiring rescue antiemetics, and the total number of parturients with no vomiting and/or no antiemetic medication (P < 0.05 to P < 0.01 ), The differences between dexamethasone 10 mg and 5 mg were not significant. Dexamethasone 2.5 mg was partially effective.Conclusion: Dexamethasone, 5 mg iv, is suggested as the minimum effective dose in preventing nausea and vomiting associated with epidural morphine for post-Cesarean analgesia.

• A new (R)-hydroxynitrile lyase from Prunus mume: asymmetric synthesis of cyanohydrins

  日期：2005.11

  A new hydroxynitrile lyase (HNL) was isolated from the seed of Japanese apricot (Prunus mume). The enzyme has similar properties with HNL isolated from other Prunus species and is FAD containing enzyme. It accepts a large number of unnatural substrates (benzaldehyde and its variant) for the addition of HCN to produce the corresponding cyanohydrins in excellent optical and chemical yields. A new HPLC

  从日本杏（Prunus mume）的种子中分离出一种新的羟腈裂解酶（HNL ）。该酶与从其他李属物种中分离的HNL具有相似的特性，并且是含FAD的酶。它接受大量非天然底物（苯甲醛及其变体）以添加HCN，从而以优异的光学和化学收率生产相应的氰醇。针对该酶开发了一种新的基于HPLC的对映选择性测定技术，该技术可促进在缓冲溶液（pH = 4.5）中将KCN添加到苯甲醛中。
