All data were collected, tabulated and statistically analyzed using SPSS 22.0 for windows (SPSS Inc., Chicago, IL, USA). <strong>Results:</strong> Of the 30 units, the majority more than 80% of the units achieved the infrastructure and schematic structure, contain water purification devices, good infection control policies, proper chemical disinfection, good monitoring and quality control, accepted maintenance technician evaluation and collected processed water samples results matched decree of 63 for 1996. <strong>Conclusion:</strong> Most of the studied units nearly fulfilled the standard specifications of both MOH and AAMI. Ensuring that water quality meets AAMI standards and recommendations will minimize patient exposure to potential contaminants such as chemical hazards and endotoxemia associated with the use of the treated water for HD.展开更多

The early step in the pathogenesis of acute pancreatitis is probably the capillary endothelial injury mediated by oxygen-derived free radicals. N-acetylcysteine - a free radical scavenger may be potentially effective in preventing post-ERCP acute pancreatitis and it is also known that N-acetylcysteine （ACC） can reduce the severity of disease in experimental model of AP. METHODS： One hundred and six patients were randomly allocated to two groups. Fifty-five patients were given N-acetylcysteine （two 600 mg doses orally 24 and 12 h before ERCP and 600 mg was given iv, twice a day for two days after the ERCP）. The control group consisted of 51 patients who were given iv. isotonic saline twice a day for two days after the ERCP. Serum and urine amylase activities were measured before ERCP and 8 and 24 h after the procedure. The primary outcome parameter was post-ERCP acute pancreatitis and the secondary outcome parameters were differences between groups in serum and urine amylase activity. RESULTS： There were no significant differences in the rate of post-ERCP pancreatitis between two groups （10 patients overall, 4 in the ACC group and 6 in the controlgroup）. There were also no significant differences in baseline and post-ERCP serum and urine amylase activity between ACC group and control group. CONCLUSION： N-acetylcysteine fails to demonstrate any significant preventive effect on post-ERCP pancreatitis, as well as on serum and urine amylase activity.展开更多
