BACKGROUND: Disinfection is essential for the prevention of hospital infoction. Tego-51, one of the amphoteric surfactants based on the dodecyl-di( aminoethyl)-glycine, has been considered as an effctive disinfectant having a broad specturn of antimicrobial activity. We evaluated the disinfective activity of Tego-51 against several clinical isolates of bacteria and yeasts including Helicobacter pyiori. METHODS: Twenty three strains of vacteria including H. pylori, and a strain of yeast were exposed to the various concentrations (0.05%, 0.01%, 0.005%) of Tego-51 for the various periods (0.5, 1, 2, 4, 8, 16min). After the exposure to Tego-51 disinfectant, 0.01 mL of mixture of microorfanisms and Tego-51 was inoculated into brain-heart infusion broth, into Sabouraud dextrose agar. or Wilkins-Chalgren agar with 10% sheep blood, and incubated at 37 degrees C for 48 hours or in the Campy Pouch microaerophilic system. RESULTS: Most strains were killed within 30 seconds after an exposure to 0.01% of Tego-51, but Proteus mirabilis was eradicated after two minutes of exposure. At the concentration of 0.005 % concentration. P. mirabilis and Bacillus subtilis were killed after eight minutes od exposure. H. pylori was killed with 0.005% Tego-51within 30 seconds. Conslusions: This study showed that Tego-51disinfectant was effective for the disinfection of commonly isolated bacteria and yeast from hospital. It may be recommended that Tego-51 should be used at concentration greater than 0.1% for the effective disinfection of skin, instruments and hospital floors.

We evaluated the role of endoseopic balloon dilatation for esophageal strictures caused by postoperative anastomosis in 5 cases, sclerotherapy in 4 cases, caustic injury in 6 cases, and malignancy in 16 cases. The success rate of balloon dilatation was 100% in postoperative anastomotic and post-scle- rotherapy strictures, 16.7% in caustic stricture, and 62.5% in malignant stricture. The addition of bougienage increased the final success rate of dilatation therapy from 16.7 to 66.7% in caustic stricture, and 62.5 to 93.8% in malignant stricture. The overall one-year recurrence rate in benign stricture was 34.5%. All of the recurrent strictures were successfully retreated by balloon dilatation. In conclusion, endoscopic balloon dilatation is a safe, effective, and easy method for the management of benign esophageal strictures except longstanding caustic stricture, and can be used as an auxiliary therapy prior to more definitive treatments such as esophageal intubation in malignant stricture.

Understanding of brain morphology and magnetic resonance image(MRI) is essential for accurate diagnosis and treatment of the brain diseases. As education tools, the cadaver dissection, plastic models, and neuroanatomy books have been used for understanding brain morphology; and the MRI films and radiology books have been used for understanding brain MRI. Recently, due to the popularization of powerful personal computers, computer programs compensating the conventional education tools have been used. But these computer programs have a disadvantage that it is not possible to visualize the details of brain morphology or to compare the corresponding sectioned specimens and MRI. Therefore, we attempted to make a computer program which could visualize not only the details of brain morphology but also the corresponding sectioned specimens and MRI by using the brains removed from Korean cadavers. Three brains were removed from Korean cadavers. With a brain, 122 MRI and 122 serially-sectioned specimens with an 1.4mm interval were acquired and inputted into the computer. Ten brain structures were segmented, and 83 fine structures were designated on the images. With two brains, 27 dissected specimens were acquired and inputted into the computer. One-hundred two fine structures were designated on the images. Based on these images, a computer program for understanding brain morphology and MRI was made. The computer program, which was made in this study, visualized the corresponding sectioned specimens, MRI, and segmented images after sectioning a brain horizontally or at any angles. In addition, the computer program visualized the images of dissected brain. This computer program is helpful to understand brain morphology and MRI. This computer program is expected to be used through CD-title or Internet as an educational tool for medical students and doctors.
