MethodsEthanol was used to establish the gastric ulcer model in mouse gastral cavity. The contents of NO,NOS and ET in peripheral tissues of gastric ulcer were detected (P＜0.01). ResultsThe UI of berberine-treated groups (25,50 mg/kg) was less than that of the model group.

现代医学研究表明berberine具有抗菌、止泻、抗炎、免疫抑制等多种药理作用［1］；崔学军等［2］在总结berberine的药理作用及临床新用途时发现它还具有良好的保护胃黏膜、抗溃疡作用；Berberine与其它药联合使用治疗消化性溃疡的临床资料也不少，但作用机制并未阐明。

Surgical therapy is the first choice for the recurrent stomal ulcer with complications and BAO,MAO obviously higher,stomal resection and gastrojejunal Roux-en-y anastomosis are effective methods to treat the stomal ulcer,and conservative treatment should be chosen primarily for the patients with slightly elevated BAO,MAO.

胃部分切除术后发生吻合口溃疡的主要原因为胃酸高所致，对有明显并发症且基础胃酸、最大胃酸明显高于正常者应采取外科手术治疗，原吻合口切除、胃空肠Roux-en-y吻合是治疗吻合口溃疡的有效方法。对BAO、MAO增高不明显者可用内科治疗，效果较好。

Methods From July 2001 to August 2002, eighty-one patients wi th haematemesis and/or hematochezia diagnosed as peptic ulcer by immediate endos copy were divided into two groups based on Forrest grading, 41 were treated with injection therapy; other 40 with conservative therapy only.

选自 2 0 0 1年 7月至 2 0 0 2年 8月因呕血和黑便入院，经紧急内镜检查确诊为溃疡性出血患者 81例，溃疡出血按Forrest镜下表现分级，内镜注射止血治疗组 4 1例，内科治疗组 4 0例。

Generally understanding the etiology and pathogenesis of gastroduodenal ulcer ; being familiar with the features of Clinical manifestations; mastering the surgical indications; generally understanding surgical methods and surgical complications; being familiar with clinical manifestations, diagnosis and treatment principles of cicatricial pyloric obstruction, acute hemorrhea and acute perforation of gastroduodenal ulcer.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
