BACKGROUND: This study aims to obtain basic data regarding the proper maintenance and potential role of humidifiers in the development of nosocomial pneumonia. We investigated into a spectrum of bacteria that grew after disinfection in humidifiers that were used in intensive care units (ICUs). The bacteria were isolated at different time points after disinfection. METHODS: We randomly selected 6 humidifiers that were used in an ICU and conducted a series of bacterial culture studies at 24 hr, 48 hr, 72 hr and 168 hr after disinfecting the six humidifiers. The fluid from the humidifider was cultured in the same manner as the dialysate. RESULTS: No bacteria were isolated in most of the 6 humidifiers 24 hr after the disinfection of the instruments. Gram-negative bacilli such as Acinetobacter baumannii, Burkholderia cepacia, and Stenotrophomonas maltophilia were cultured at 48 hr after disinfection. CONCLUSION: Regular and thorough disinfection of humidifiers is necessary to prevent possible spread of infection via humidifiers in the ICU.

The objective of this study is to examine the correlation between the tolylene concentration in the work environment of organic solvents and the concentration of hippuric acid in urine of workers exposed toluene, and to acquire the fundamental materials of workers' health care and to assist the assessment of the biological permissible exposure limit. The control groups are 72 workers who had never been exposed to toluene and the case groups are 101 workers who had been exposed to toluene. This study was conducted to examine the correlation between the concentration of toluene in work environment and workers' hippuric acid concentration, to investigate the complaint difference of subjective symptoms by means of questionnaire, between the case groups and control groups. The results and conclusions are as follows: 1) The highest mean concentration of toluene in the air is 544.13+/-7.75 ppm in the Printing Department of mixing organic solvents. The concentrations of the others are 463.27+/-5.24 ppm in Department of mixture for organic solvents, and 393.56+/-45.69 ppm in the Printing Department(1), and 248.38+/-45.16 ppm in the Printing Department(2), and 159.38+/-18.51 ppm in the Printing Department(3). 2) The highest mean concentration of hippuric acid in urine is 6034.84+/-1298.35 mg/l in the Printing Department with mixing organic solvents. The concentrations of the others are 4798.44+/-784.53 mg/l in Department of mixture of organic solvents, and 2883.06+/-701.90 mg/l in the Printing Department(1), and 1449.98+/-905.19 mg/l in the Printing Department(2), and 598.52+/-299.43 mg/l in the Printing Department(3). 3) As the toluene concentration in the work environment becomes higher, the concentration of hippuric acid in urine also becomes higher. It is found that the coefficient of correlation between toluene concentration and the concentration of hippuric acid are positive (r=0.868, Y=7.18X+349.57). 4) It is found that the case groups complain of much more subjective symptoms than the control groups.

The purpose of this study was to investigate dietary habits, dietary attitudes, perceptions for nutritional importance, nutritional knowledge and frequency of food intake to get the basic data of effective nutritional knowledge to form desirable dietary habits of students. This study was carried out through a questionnaire. The subjects were 362 teenagers (boys 161, girls 201) in some farming and fishing regions of Jeonnam. The most desirable dietary habit was that both boys and girls never skipped their lunch, the undesirable dietary habit was that boys ate too fast and girls had too many snacks. While boys ate faster than girls (p < 0.01), girls skipped dinner more frequently than boys (p < 0.01). In terms of dietary attitudes, boys had more desirable attitudes than girls in that they "choose nutritious food" (p < 0.01), "enjoyed healthy food more than favorite food" (p < 0.01), "think about basic food groups when having something" (p < 0.01) while girls had more desirable attitudes than boys in that they "only have favorite food" (p < 0.01). In nutritional knowledge, girls showed a percentage of more correct answers than boys in "is likely to suffer anemia without enough iron" (p < 0.05), and "it doesn't need to eat fat, which causes obesity" (p < 0.05). In general, girls had higher nutritional knowledge than boys. For frequency of food intake, boys ate more fried and broiled food than girls (p < 0.05). In general, boys had nutritional unbalanced diets more than girls. As a result, girls had higher levels of nutritional knowledge and boys had more desirable dietary habits and attitudes. We should have systematic and repetitive education about nutrition so that teenagers could practice their nutritional knowledge in diets. Moreover, it is necessary to develop proper education for their genders.

We performed immunohistochemical stain of p-glycoprotein using JSB-1 monoclonal antibody to study multidrug resistant(MDR) gene expression in 137 gastric tumor tissues obtained from 87gastric carcinoma patients. The incidence of p-glycoprotein expression was 60 of 87 cases(69%) and it was not correlated with age, sex, depth of tumor invasion, and lymph node metastasis, but was correlated with histologic type of gastric adenocarcinoma. The distribution of p-glycoprotein positive cells in the tumor tissue was diffuse in 34 cases(73.9%) and focal in 12 cases(26.1%), and the dominant staining patterns of p-glycoprotein in the tumor cells were cytoplasmic and golgi staining in 20 cases(43.5%) and 19 cases(41.3%), respectively, and 7 cases(15.2%) showed fine granules in the cytoplasm. The incidence of p-glyco-protein expression in the tumor tissue was higher in A and AB blood type patients who have A antigen than in 0 and B blood type patients. Cytoplasmic staining pattern was dominant in O and B blood types and golgi staining in A and AB blood type patients. Among 27 patients 'who received chemotherapy, partial remission was noted in 9 of 11 p-glyco-protein negative patients(81.8%) and no remission or progression of the tumor was seen in 9 of 16 p-glycoprotein positive patient(56.3%). The p-glycoprotein expression in gastric carcinoma had no direct correlation with known several prognostic factors of the gastric tumor except for histologic type, and it is supposed that p-glycoprotein detection in gastric tumor tissue by immunohisto-chemical stain is a good method for predicting the response of chemotherapy, especially in p-gly-coprotein negative cases.
