Background & Objective: Flatulence is one of the most common postoperative disorders, which leads to abdominal distension, respiratory disorders and the openning of sutures. Some of the drugs used to alleviate the abdominal flatulence are associated with complications and harmful effects, which gives us a hint to adopt herbal medicine. The present study investigates the effect of supermint on the flatulence intensity after cesarean section.

  Methods: This double-blinded clinical trial study was conducted on 107 women (47 cases as placebo group and 60 cases as drug group) who had cesarean section in shahid Mobini hospital, Sabzevar. After stopping the administration of IV fluid, the subjects in both groups received 40 drops of drug and placebo every 20 minutes for 3 days.

  Results: The intensity of flatulence in the first 20 minutes (p=0.042), in second 20 minutes (p=0.001), in the third 20 minutes (p<0.001) and 120 minutes after intervention (p<0.001) was lower in drug group compared to before intervention.

  Conclusion: Supermint is effective in reducing the postoperative flatulence in cesarean section and is recommended to be used in these cases.

  Background & Objectives : Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder that is common through the world including Iran. Because of its chronic nature and lack of effective treatment, patients are always anxious and stressful and physicians are also exhausted of untreated patients. The cause of IBS is unclear and it has not effective treatment. Therefore, there is a need to find and introduce a proper method of treatment to control symptoms including abdominal pain and defecation changes. This study was aimed to determine the effectiveness of probiotic yogurt on the general relief of symptoms associated with IBS.

  Methods : Subjects were recruited from patients of gastroenterology clinic in Imam Khomeini Hospital, Ardabil. A total of sixty patients fulfilling the Rome II criteria took part in this study. Subjects were randomized into two groups of trial and control. Pre- and post- treatment symptoms were investigated using a questionnaire. Thirty one patients received probiotic and 29 patients normal yogurt for 4 weeks. Bottles of yoghurt were manufactured, and coded by a company. Both participants and researcher were blinded for the bottles' code. The symptoms were followed before and after two and four weeks of treatment and two weeks post- discontinuing of trial, too. Data were analyzed by SPSS (Ver. 17) and differences between groups were compared statistically using of chi-square and t-test.

  Results: A total number of 60 patients were recruited in this study of whom 36 (60%) were female and 24(40%) male. The average age of participants was 34.1±9 which did not differ between two groups. The onset of symptoms did not show any difference between two groups. The trial group had a history of 5.7±5.1 years while this was 6.5±4.9 for the controls. In overall, patients who were given probiotic yogurt had shown a better response in the control of abdominal pain and flatulence than those who were treated with normal yogurt. There was not a significant difference between two groups in the response to treat for other symptoms including epigastric pain, vomiting, frequency of defecation and feces consistency.

  Conclusion: According to our research, adding probiotic yogurt to the patient diet may help ease symptoms of IBS especially, abdominal pain and flatulence. Considering the high prevalence of irritable bowel syndrome and the lack of effective therapies, even a slight reduction in symptoms can have positive public health consequences.
