A double-blind controlled therapeutic trial of glycyrrhizinic-acid-reduced liquorice 760 mg thrice daily for six weeks was carried out on 90 men with relapse of chronic duodenal ulcer. Effects of treatment were judged by the frequency and severity of pain, the amount of alkali consumed, and the doctors' and patients' rating of the clinical response. The results do not show any advantage for the active treatment when compared with the placebo.
对90名慢性十二指肠溃疡复发的男性患者进行了一项双盲对照治疗试验,给予甘草酸含量降低的甘草制剂,每日三次,每次760毫克,持续六周。通过疼痛的频率和严重程度、碱消耗量以及医生和患者对临床反应的评分来判断治疗效果。与安慰剂相比,积极治疗未显示出任何优势。
