METHODS： We retrospectively reviewed the charts of 197 patients （81 male, 116 female） who underwent Bravo esophageal pH monitoring from July 2003 to January 2008. All patients underwent Bravo pH probe placement via esophagogastroduodenoscopy （EGD） and received propofol for sedation. Patients on a proton pump inhibitor （89 patients） were excluded. Acid reflux variables measured included the total, upright, and supine fractions of time at pH 〈 4 and DeMeester score, and were compared between day I and day 2. RESULTS： Of the 108 patients that were included in the study, the most common indication for Bravo pH monitoring was heartburn, with chest pain being the second most common. A signed rank test revealed no statistically significant difference between day I and day 2 reflux episodes. CONCLUSION： Patients who received propofol for sedation for EGD with Bravo pH capsule placement did not experience any significant difference in reflux episodes from day 1 to day 2.展开更多

In this research, removal of Orange II, Remazol Blue, Methyl red, Malachite green and Safranin dyes by Pseudomonas fluorescens was studied in batch system as function of temperature, pH and initial dye concentration. The rate of removal dyes was studied by using pectrophotometer. The optimum value was determined as pH 7 for all dyes tested about 87.8-72.7%, and optimum temperature for removal of all tested dyes was 30℃ about 86.6-60.8%. Higher removal of dyes observed at 25 mL for all tested dyes about 91.9-72,7%. In general, the increase in dye concentration inhibited the growth of bacteria. Pseudomonasfluorescens showed higher removal of Orange II among the dyes tested.展开更多
