Effect of Modified Simotang on Adult Functional Constipation and Intestinal Neurotransmitter / 中国实验方剂学杂志

ABSTRACT

Objective:To observe the efficacy of modified Simotang in treatment of adult functional constipation (Qi-stagnancy constipation), and investigate its effects on serum levels of intestinal neurotransmitter nitric oxide synthase (nNOS), nitric oxide (NO), and vasoactive intestinal peptide (VIP), as well as superoxide dismutase (SOD), malonaldehyde (MDA), and glutathione (GSH) levels. Method:One hundred and ten patients with functional constipation were selected and randomly divided into control group (55 cases) and treatment group (55 cases) by referring to random number table. The patients in control group were given with routine therapy, Domperidone tablet (1 tablet/time, tid), and Phenolphthalein tablets (100 mg/time, bid). The patients in treatment group were treated with modified Simotang, 1 dose/day. Both groups were treated for 4 weeks. Then the scores of main clinical symptoms of functional constipation, scores of Qi-stagnancy constipation and clinical efficacy were compared between two groups. Constipation recurrence rate was compared between two groups after stopping medicine. Serum levels of intestinal neurotransmitters nNOS, NO and VIP as well as SOD, MDA, GSH levels were detected in both groups. Result:After treatment, scores for main clinical symptoms (difficult defecation, abdominal distension, defecation time, number of defecation times) and Bristol scores in treatment group were obviously lower than those in control group (PP PPPPConclusion:Based on routine therapy, modified Simotang in treatment of adult functional constipation (Qi-stagnancy constipation) can improve clinical symptoms and syndrome symptoms, increase the clinical efficacy, decrease recurrence rate, and regulate levels of intestinal neurotransmitters nNOS,NO and VIP as well as SOD, MDA, GSH levels.
