A retrospective morphological study was conducted on 1677 lymph nodes which were removed surgically under the diagnosis of gastric carcinoma, breast carcinoma, colonic carcinoma, chronic gastric ulcer, and superficial lymph nodes nuder the diagnosis of reactive follicular hyperplasia at Chosun University Hospital during a period of 5 years from 1980 to 1984. The hematoxylin and eosin stained sections were examined to evaluate for any vascular changes. In selected cases further levels were prepared from the paraffin blocks for Gomori's reticulin stain. The vascular abnormalities were divided into 3 groups, such as hemangiomatoid, pan-nodal vasodilatation and miscellaneous types. The miscellaneous type included the proliferation of smooth muscle which encircled numerous small hilar arteries and veins. The results obtained were as follows: 1) The hemangiomatoid lesions were localized lesions which appeared to be associated with local malignancy, but infrequent in incidence. 2) A more frequent vascular abnormality was pan-nodal vasodilatation, which tend to affect many nodes in a single group and is relatively associated with chronic gastric ulcer. 3) Miscellaneous lesion was nonspecific and appeared both local malignancy and chronic inflammation. 4) All three vascular reactions were somewhat more frequent in female than male.

The study conducted from May to September in 1994 to investigate applicability of the Hearing Handicap Inventory for the Elderly-Screening version(HHIE-S) in parallel with the puretone audiometer to the initial screening test of noise-induced hearing loss(NIHL) in some noise-exposed workers. Subjects were selected by systemic sampling that took every fifth person from 6,700 workers taking the annual occupational health examination by the department of Health Maintenance of Dongsan Hospital Keimyung University in Taegu. The authors administered the pure-tone audiometric test and self-reported questionnaire of HHIE-S including items of sociodemographic and job-related variables concurrently. The final subjects analysed were 1,019(488 males and 531 females) excluding fourteen persons who had many missing values in their questionnaires. The reliability coefficients of HHIE-S scale by Cronbach's alpha were 0.84. In the univariate analysis of hearing handicap measured by the HHIE-S, work duration, military service and the hearing threshold loss at 1kHz and 4kHz was the only selected variable explaining the hearing handicap in males and hearing threshold loss at 1kHz and 4kHz, age, and work duration were selected in females. In ROC curves for HHIE-S scores against NIHL as gold standard which was defined by the follow-up audiogram as more than 30dB of the average of 0.5/1/2kHz and 50dB at 4kHz, the optimal cutoff for the parallel HHIE-S appeared to be 8. The results suggest that HHIE-S appeared to have some reliability and validity in this data and might be used in screening NIHL in parallel with pure-tone audiometer in noise-exposed workers.

We are calling the erupting ground water as drug water or mineral water in Korea and thinking those water and food making water. Authors tried to investigate the evidence of contamination by user on the 10 erupting ground water and gained following results: 1. All of the mineral waters on 10 area in Seoul were unfittable to drinking water standard. 2. In the view of the bacteriology 80% were contaminated by coliform group. 3. The highest value of the free carbon dioxide contents were 652.96 ppm at Sam Sun Mineral Water.

OBJECTIVES: In order to evaluate the relationship between daily mortality and air pollution in Deagu for the period by the data from January 1993 to December 1997. METHODS: Deaths from accident(International Classification of Disease, Revision 9; 800-999 and Revision 10; V01- Y89) were excluded, Daily counts of deaths were analysed by general additive poisson model on the current day to 5 days before death, with controlling for effects of year, season, weather, weekday and holiday. The air pollutants examined included total suspended particulate (TSP), sulfur dioxide (SO,), nitrogen dioxide (NO,), carbon monoxide (CO) and ozone (03). RESULTS: Mortality was associated with NO, SO and CO in the air. Total mortality was estimated to increase by 1. 6 % (95 % CI 0. 3-3 %) with each 10 ppb rise in NOy on the current day and the preceding 1 day, 9. 4 % (95 % CI 7 13 %) with each 100 ppb rise in SOy and 2. 7 % (95 % CI 0. 1 5 %) with each 1 ppm rise in CO on the current day. The NO was more evident for the elderly who were 65 years and more. Cardiovascular-specific mortality was associated with the levels of CO on the current day. Respiratory-specific mortality was associated with the levels of TSP and NO 5 days before death. Excess mortality risk is clearly evident in the upper range of NO levels and increased monotonically with NO. CONCLUSIONS: This study suggested that the air pollution status below the current Korean ambient air quality standard might have an adverse effect on daily mortality. Then, it is impertive that the strategy for control of the air pollution-related daily mortality should be developed.
