    Abstract

    AIM To evaluate the disinfecting effect of electrolyzed acide water on gastroendoscope.

    

    METHODS Patients (130) for gastroscopic examination were divided into 3 groups. Wipe out the surface of the endoscope with sterile absorb ent gauze immediatedly after endoscopic examination and inject 2mL of sterile saline into the forceps channel. Some liquid flowing out from the tip of the scope was collected. The gauze and the liquid were inoculated in the culture dish for bacterial culture. Fifty-two samples were taken for common bacterial culture and 68 were taken for Helicobacter pylori culture. Then electrolyzed acid water produed by a disinfectant apparatus, CLEANTOP WM-1, was used to disinfect the endosope for 7 minutes, sample collection and bacteria l culturing were performed in the same way. Quantitative sterilizing test with electrolyzed acid water was conducted to detect its disfecting effect on various types of bacteria. Samples taken from 10 subjects with HBsAg positive were tested for HBV DNA by polymerase chain reaction (PCR) assay before and after disinfection with electrolyzed acid water in the same way. ......
