This study was carried out for 5 years between 1984 and 1986 and 1989 and 1990. This interviewers visited 292 households to evaluate the perception of the residents using the Simple Piped Water Supply (SPWS). and examined the pollution source surrounding 42 SPWS facilitiesld water quality by the chemical and microbiological method. The purpose of this study was to find out problems linked with SPWS and to investigate more efficient way of improvement in rural water supply. The results of the study are surrunarized as follows : 1) Approximately 55% of the sampled population have been served by simple piped water supply. 2) The drinking water was mostly taken from the springs in 16 sites and valley water in 26 sites. 3) Considering the type of distribution of the SPWS. there are 28 natural gravity systems and 14 pumping systems. 4) Out of the 180 SPWS in Chun Sung Area, 74% of the SPWS facilities were used more than ten years. In addition, 40% of residents expressed the need for repairs of old facilities. 5) 48% of the SPWS facilities are neighbored with pollution source. 6) 50% of the maintenance crews were not committed totheir job but instead. the facilities were operated by some residents or community leaders who were personally concerned about quality of the faci1ities. 7) About 85% of the residents answered that SPWS was convenient and helpf비. 8) About 57% of the residents complaind that the amount of daily water supply is not adequate. 9) About 74% of the residents felt that the water quality is high for dringking water and therefore, 52% of the facilities were not pro야r1 y chlorinated. But in contrast, the biochemic tests indicated that only 28% of the SPWS met the dringking water quality standards. 10) Maintenance cost per a household ranges form 500 to 2,000Won (1 $ =700 Won) a month. Most of the cost was to cover the power electric charge. For the effective rnaintenance and arrangement of the facilities, gorvermental financial support for the rnaintenance is strongly recommended.

N/A Using an intravenous radionuclide method, an intrapulmonary shunt was measured before and after removal of pleural fluid or air by thoracentesis or chest tube insertion in 8 patients with pleural diseases. Of the patients entered in the study, 3 had tuberculous pleurisy, 3 had pneumothorax and P, bad malignant pleural effusion. Shunt changes in the posttreatment state(10.6±3.5 %) compared to that in the pretreatment state(8.0±2.7 %) were statistically significant(p<0.01). In patients with tuberculous pleurisy, shunt changes were especially remarkable.

N/A γ-glutamyl transpeptidase (γ -GTP) was examined to see the incidence and specificity of the novel band in the field of diagnosis of primary hepatocellular carcinoma. Serum γ -GTP was fractionated by polyacrylamide gradient gel electrophoresis from the sera of 50 patients with various hepatobiliary diseases, including 20 with primary hepatocellular carcinoma (HCC). γ -GTP isoenzymes in the sera were separated by this method into 10 bands. Novel band, which was seen in the region near the ceruloplasmin, was detected in 15 of 20 patients with hepatocellular carcinoma (75%). Specific γ -GTP was found in 25% of HCC patients with alphafetoprotein (AFP) levels below 400 ng/ml. The incidence of this isoenzyme was independent of the clinical stage as classified by liver scanning, Even in Stage I, where filling defects were not seen, the incidence was remarkable. We conclude that this novel γ -GTP isoenzyme seems to be 1) a useful diagnostic index for hepatocellular carcinoma and 2) a relatively useful marker for early detection of HCC patients, even in Stage I, which has no filling defect on the liver scan. In addition, we need more studies for confirmation of the usefulness of γ -GTP isoenzyme for diagnosis of HCC patients with lower serum AFP levels.

N/A Pseudomembranous enterocolitis has been recognized since the 1880s as a severe intestinal lesion associated with a variety of conditions, In recent years, the majority of cases have been ascribed to antimicrobial treatment. Several studies have shown that C. difficle is the major cause of antibiotic associated pseudomembranous enterocolitis, Clinically, the disease is manifested by the diarrhea, abdominal pain, and fever. We wish to report our experience of 24cases of pseudomembranous enterocolitis associated with antibiotics, diagnosed by identifying characteristic yellow-white plaques, using with sigmoidoscopy that showed a pseudomembrane or summit lesion on a biopsy. The results were as follows: 1) There were 11 male and 13 female patients. Seventy-nine percent of the patients were over 50 years old at the time the diagnosis was made. 2) Various symptoms were assoicated with the onset of the disease, the most common being diarrhea (100%), abdominal pain (63%), and fever (54%). 3) Seventy-nine percent of patients developed diarrea within 15 days of antimicrobial chemotherapy. 4) Underlying medical illness were malignant tumor (21%), chronic renal failure (21%), colitis (12.5%), sepsis (8.3%), diabetes mellitus (8.3%), pneumonia (8.3%) and others. 5) Causes of antimicrobial therapy were prophylatic purpose (21%), pneumonia (21%), urinary tract infection (16.7%), enterocolitis (12.5%) and others. 6) Implicated antibiotics were ampicillin (45.8%), cephalosporin (29.1%), clindamycin (16.7%), penicillin (4.2%) and rifampin (4.2%) 7) Symptoms were improved with in 7 days, with medical agents such as vancomycin, metronidazole, lactobacillus, cholestyramine, and with only discontinuation of implicated antibiotics.

윤효정,정문호,Yoon, Hyo-Jung,Chung, Moon-Ho 한국환경보건학회 2005 한국환경보건학회지 Vol.31 No.4

Permethrin, a synthetic pyrethroid insecticide, has been widely used to protect domestic animals and the public health, as well as in agriculture against a variety of pests, which provides potential for environmental exposure. Permethrin is classified as possible human carcinogen and endocrine disrupting chemical by many international authorities. However, its developmental effects have been rarely studied. This study investigated the effects of permethrin during embryo-genesis. Developmental toxicity of permethrin was evaluated using short-term in vitro battery system. Gestation day 9.5 rat embryos (organogenesis) were cultured with permethrin (0.1,0.4 and 0.8 mg/ml) for 48 hours using whole embryo culture system. All the treatments exhibited significant decreases in the total morphological score. Permethrin induced significant growth retardation and the developmental abnormality at doses of 0.4 and 0.8 mg/ml. Moreover, the DNA and protein contents of embryos decreased in dose-dependent manner. These observations suggest that permethrin contributes to toxicity on embryonic developments in rats.
