Starting with two reactive methylene compounds, ethyl cyanoacetate and malononitrile, two 5-amino-1H-pyrazoles were prepared through the intermediates ketene dithioacetal.

从两个活泼亚甲基化合物开始，经过乙烯酮二硫代缩醛中间体，合成了两个5-氨基-1H-吡唑，以这个两个化合物为中间体，与芳香族和脂肪族α-溴代酮反应，而后经酸催化亚胺化互变异构后得到含咪唑并[1，2-b]吡唑甲硫醚类化合物6a-6g。

Taking 4-bromobenzaldehyde, acetic, benzaldehyde and ammonium acetate as major raw material, the 4, 5-bis(4-bromophenyl)-2-phenyl-1H-imidazole was synthesized by means of catalysis, oxidation and Debus cycloaddition reaction.

以对溴苯甲醛为原料通过催化，氧化生成1，2-二（4'-溴苯基）乙二酮，再以其与苯甲醛、醋酸胺和醋酸通过德布斯法合成2-苯基－4，5-二（4'-溴基苯基）咪唑。

We performed this study to examine the effects of IV-administeredmidazolam on somatosympathetic A and C reflex discharges inbrain-intact cats and decerebrate cats (with transection atmidbrain level).

本次试验，分别对完整大脑和去大脑状态的猫静脉注射咪唑安定后，观察对躯体交感神经 A ， C 反射的影响。

Similar responses were obtained in decerebrate, isoflurane-freerats administered etomidate and in isoflurane-anesthetized ratsadministered propofol.

在去大脑、给予依托咪酯未用异氟醚的大鼠或给予异丙酚的异氟醚麻醉大鼠，也可以记录到相似的反应。

After controlsomatosympathetic reflex responses were obtained, midazolamwas administered IV to four groups of randomly allocated catsas follows: brain-intact cats at a dose of 0.03 mg/kg, brain-intactcats at a dose of 0.1 mg/kg, brain-intact cats at a dose of0.5 mg/kg, and decerebrate cats at a dose of 0.1 mg/kg.

控制下的体－交感反射产生后，我们把猫随机分成四组，分别静脉注射如下剂量的咪唑安定：大脑完整的猫注射剂量分别为0.03mg/kg 、 0.1mg/kg 、0.5mg/kg；去大脑的猫注射剂量为0.1mg/kg。

RESULTS Duodenal ulcer was the first cause of upper gastrointestinal hemorrhage. Gastric ulcer, cirrhosis, Mallory-Weiss syndrome or acute gastric mucous lesion was the second cause of the illness alternatively. The rate of endoscopy and emergent endoscopy has been going up year after year and got up to 80% in 1998. Bleeding and active hemorrhage, respectively were found in 24.3% and 14.9% of the patients underwent endoscopy before medication. Endoscopic hemostasis was performed in 108 patients by spraying hemostatics and a good response was achieved subsequently. Hemostatics were mainly cimetidine and yunnan baiyao before 1994. Reptilase, pPI, famotidine and ranitidine were used increasingly while cimetidine and yunnan baiyao were used decreasingly. Octreotide was used in patients with cirrhosis commonly. The length of hospital stay and the period from admission to bleeding cease tended to be shorter year by year, but the reduction rate was small. The uses of ranitidine, famotidine, pPI, reptilase, octreotide, early endoscopy and endoscopic therapy may play a role in improving the therapeutic effect of hemostasis, reducing the hospitalization and the mortality.

结果 十二指肠球部溃疡是历年上消化道出血的首要原因，胃溃疡、肝硬变、Mallory -Weiss综合征、急性胃粘膜病变则交替成为第2位出血原因；内镜诊断率和急诊内镜率逐年提高，1998年达到80%，内镜下见出血者占内镜检查的24.3%，而见到活动性出血者仅占内镜检查者的14.9%；内镜下止血108例次，成功率100%；1994年前治疗药物主要为云南白药和甲氰咪胍，之后，随着立止血、质子泵抑制剂、法莫替丁、雷尼替丁等药物使用的逐渐增多，前二者的使用逐渐减少，善得定多用于肝硬变出血；住院天数和止血天数呈逐年下降的趋势，但幅度微小；雷尼替丁、法莫替丁、PPI、立止血、善得定的使用以及及时的内镜检查和内镜下治疗在提高止血效果、缩短住院天数、降低死亡率方面可能起到了一定作用。

The important factor, which influence degradative rate to imazapyr in soil, is organic matter content and pH values.
