偶氮磺胺吡啶虽然广泛用于治疗溃疡性结肠炎,但该药贵且有很大副作用;5-氨基水杨酸(5-ASA)虽无副作用但亦很贵。本文作者试用4-氨基水杨酸(4-ASA)灌肠剂对10例溃疡性结肠炎患者进行治疗。10例患者治疗前每天排便6～10次;临床评分(症状越重得分越高):便血、粪便中的粘液、腹痛、里急后重等均为2～3分;乙状结肠镜Ⅲ～Ⅳ Although widely used in the treatment of ulcerative colitis, azo-sulfapyridine is expensive and has a large side-effect; 5-aminosalicylic acid (5-ASA) is also expensive without side effects. The authors tested 4-aminosalicylic acid (4-ASA) enema in 10 patients with ulcerative colitis. 10 patients were defecated 6 to 10 times a day before treatment. The clinical score (the higher the score was): blood in the stool, mucus in the stool, abdominal pain, tenesmus, etc. were all 2 ~ 3 points; sigmoidoscopy Ⅲ ~ Ⅳ
