Misoprostol vs. oxytocin for induction of labor at term.

Efficacy of misoprostol was studied for induction of labor at term. Seventy patients were randomized to Group A (n = 36, oral misoprostol 50 microg four hourly to maximum of 5 doses) and B (n = 34, continuous oxytocin infusion). Induction-delivery interval was shorter with misoprostol (7.7 +/- 2.8 h against 14.3 +/- 4.8 h with oxytocin) but the rates of vaginal delivery, cesarean, neonatal outcome variables were similar. Hence, misoprostol is an effective agent for induction of labor at term.     

舌下含服米索前列醇配伍米非司酮在终止早孕中的应用

目的 :探讨舌下含服米索前列醇配伍米非司酮用于早孕流产的可行性、安全性及有效性。方法 :将孕周在 7wk内的孕妇随机分为舌下组、口服组各 12 0例。 2组均经米非司酮预治疗后 ,舌下组含服米索前列醇 2 0 0 μg ,1h后重复 ,总量不超过6 0 0 μg ;口服组单次口服米索前列醇 6 0 0 μg。 结果 :舌下组完全流产率比口服组高 ,清宫率比口服组低 (P均 <0 0 1) ,引 -流时间缩短 (P <0 0 1) ,阴道流血及药物不良反应两者无明显差异。结论 :舌下组终止早孕具有简便、有效 ,引 -流时间短等优点

鸦胆子茎节组培快繁体系的建立

目的：建立鸦胆子茎节组培快繁体系。方法：选用鸦胆子嫩枝为外植体,探讨基本培养基和外源激素对其离体再生的初代培养、继代增殖、生根培养的影响,并进行移栽试验。结果：鸦胆子的不定芽增殖、壮苗、生根的最佳培养基分别为MS＋6-BA1．0mg·L^-1＋IBA0.1mg·L^-1,1／2MS＋香蕉汁20g·L^-1;1／2NS＋IBA0．1mg·L^-1＋NAA0．1mg·L^-1。炼苗基质为细沙时,成活率最高。     

Class I major histocompatibility complex antigen expression on early murine trophoblast and its induction by lymphokines in vitro

The expression of paternal class I and class II major histocompatibility complex (MHC) antigens in cultures of murine ectoplacental cone trophoblast was examined using immunogold labelled antibodies and electron microscopy. Class I MHC antigens could be induced on ectoplacental cone derived trophoblast following exposure to concanavalin A stimulated T cell supernatants. Class I MHC antigens were not detected in untreated trophoblast cultures. Class II MHC antigens were never detected on trophoblast whether treated or untreated. This is the first report of the experimental induction of Class I MHC antigens on a population of normally MHC-negative trophoblast cells.     

卵巢早衰治疗策略探讨

目的　评价性激素替代治疗 (hormonereplacementtreatment,HRT)对卵巢早衰 (prematureovarianfail ure ,POF)患者的疗效 ,探讨卵巢早衰可能有效的促排卵方案。方法　采用前瞻性研究方法对 19例卵巢早衰患者 ,行HRT共 3～ 6个周期 ,观察服药前后临床症状、盆腔超声相、血清生殖激素变化及停药后卵泡发育情况 ,并对个别患者行促排卵治疗观察疗效。结果　 19例患者经HRT临床症状明显缓解。与服药前比较 ,血清卵泡刺激素 (FSH)水平明显下降 (P <0 0 1) ,血清黄体生成素 (LH)水平显著下降 (P <0 0 5 )。双侧卵巢及子宫体积无显著变化 (P >0 0 5 ) ,子宫内膜明显增厚 (P <0 0 1)。停药后 1例自然妊娠 ,1例自发排卵 ,1例用促性腺激素释放激素激动剂 (GnRHa) /绝经期促性腺激素 (HMG) /绒毛膜促性腺激素 (HCG)治疗有排卵。服药期间无肝功能损伤及其它副反应。结论　性激素替代治疗卵巢早衰 3～ 6个周期 ,可使临床症状缓解 ,血清FSH、LH明显下降 ,利于促排卵治疗成功。     

Evaluation of the effect of extra-amniotic normal saline infusion alone or in combination with dexamethasone for the induction of labor

AIM: To compare the effect of extra-amniotic normal saline solution infusion on its own, and in combination with dexamethasone on the ripening of the cervix and induction of labor. METHODS: A double-blind randomized clinical trial study was performed at Akbar Abadi Teaching Hospital in Tehran, Iran, between March 2002 and March 2003 on 84 pregnant women at a gestational age of 40 weeks or more, and with a Bishop score 相似文献
