Objective To investigate the efficacy and safety of Minilase-S on patients with dyspepsia.Methods A randomized,placebo-controlled,double blind and multicenter study was conducted.Two hundred and forty patients with dyspepsia symptoms(anorexia,fullness,abdominal discomfort and distension)were collected according to total symptom scores over 20 with visual analog scales.Each patient was randomly received either Minilase-S(2 capsules t.i.d)or placebo(2 capsules t.i.d)for 2 weeks.The symptoms scores were evaluated at treatment week 1,week 2,and 1 week after discontinued therapy.Results Two hundred and sixteen patients(105 patients in Minilase group and 111 patients in placebo group)finished the study.There was no difference in demographic data,anorexia,fullness,discomfort and distension score and the total symptom score between two groups.However,at treatment week 1,week 2 and 1 week after discontinued therapy,symptoms and total symptom score were significantly decreased in Minilase-S group compared to placebo group(all P value＜0.05).The total effective rates in treatment week 1,week 2 and 1 week after discontinued therapy were 64.76%,77.05%and 66.99%,respectinely,which were higer that those in placebo group(27.93%,37.84% and 29.36%,respectively)(P＜0.05).There was no severe side effects in both Minilase-S and placebo groups.Conclusions Minilase-S can significantly improve symptoms in patients with dyspepsia,which may be as one choice in the management of dyspepsia or in combined therapy.

BACKGROUND/AIMS: Physical and/or emotional stresses are important factors in the exacerbation of symptoms in irritable bowel syndrome (IBS). Several lines of evidence support that a major impact of stress on the gastrointestinal tract occurs via the enteric nervous system. We aimed to evaluate histological changes in the submucosal plexus (SMP) and myenteric plexus (MP) of the distal ileum in concert with the intestinal motor function in a rat model of IBS with diarrhea. METHODS: The rat model was induced by heterotypic chronic and acute stress (CAS). The intestinal transit was measured by administering powdered carbon by gastric gavage. Double immunohistochemical fluorescence staining with whole-mount preparations of SMP and MP of enteric nervous system was used to assess changes in expression of choline acetyltransferase, vasoactive intestinal peptide, or nitric oxide synthase in relation to the pan neuronal marker, anti-Hu. RESULTS: The intestinal transit ratio increased significantly from control values of 50.8% to 60.6% in the CAS group. The numbers of enteric ganglia and neurons in the SMP were increased in the CAS group. The proportions of choline acetyltransferase- and vasoactive intestinal peptide-immunoreactive neurons in the SMP were increased (82.1 ± 4.3% vs. 76.0 ± 5.0%, P = 0.021; 40.5 ± 5.9% vs 28.9 ± 3.7%, P = 0.001), while nitric oxide synthase-immunoreactive neurons in the MP were decreased compared with controls (23.3 ± 4.5% vs 32.4 ± 4.5%, P = 0.002). CONCLUSIONS: These morphological changes in enteric neurons to CAS might contribute to the dysfunction in motility and secretion in IBS with diarrhea.
