Objective : This study was done to examine the cytotoxicity of styrax benzoin (SB) on human oral epithelioid carcinoma cell line (KI3). Methods : The cytotoxic effect of SB was measured by MTT assay or XTT assay. The microscopic study was performed to observe the mophorlogical changes of KI3 cells. Results : The cytotoxic effect of SB on KI3 cells showed a significant increase at 50 uM or 100 uM SB by MTT assay or XTT assay compared with control after cells were treated with various concentrations of SB for 48 hours. MTT_(50) and XTTg were 419.9 uM and 375.5 uM, respectively. In microscopic study, KB cells exposed to SB showed both the decreased cell number and the morphological changes. Conclusion : From these results, SB has a midcytotoxicity by the showing the decrease of cell number and the morphological changes in KJ3 by MTT and XTT assays.

The purpose of study was to investigate the effects on plasma responses of β-endorphin and ACTH related to exercise intensities and group of the health program apply of the regular aerobic exercise. This study employed 30 middle-aged men(35-45yr), who did not experience such physical activities. They were divided into experimental groups(50%;10, 70%;10) and control group (60%;10), each group consisted of subjects(30min per day, 4days in a week for 12weeks; Jogging). None of the volunteers were taking any midication for at least 3 months preceding the study. Subjects fasted for 2 hours and abstrained from alcohol, tobacco, at least 24 hours prior to testing. All experioments were conducted in the same room between 16:00 and 19:00. Blood samples were collected at 30min before exercise, immediately after exercise at 3min and 30min and 60min during recovery post exercise. These hormones were determined using radioimmunoassay kit. All data were expressed as Mean and S.D, From the statistical evaluation of the data and review of related previous studies conclusions may be made as follow; 1. There were statistics significance showing, the mean of β-endorphin and ACTH of the health program apply. 2. Plasma β-endorphin levels, compared to rest, was not statistically significantly increased in control group, but significantly increased in experimental groups 50%(P<5), 70%(P<1), and were restored(96%) the resting values within R6O in experimental groups(70%) 3. Plasma ACTH levels, compared to rest, was not statistically significantly increased in control group, but significantly increased in experimental groups 50%(P<5), 70%(P<1), and were restored(99%) the resting values within R6O in experimental groups(70%).

Indoor and outdoor nitrogen dioxide (NO_2) concentrations were measured and compared with measurements of personal exposures of 95 persons in Seoul, Korea and 57 persons in Brisbane, Australia, respectively. This activity diary was used to determine the impact on NO_2 exposure assessment and microenvironmental model to estimate the personal NO_2 exposure. Most people both Seoul and Brisbane spent their times more than 90% of indoor and more than 50% in home, respectively. Personal NO_2 exposures were significantly associated with indoor NO_2 levels with Person coefficient of 0.70 (p<0.01) and outdoor NO_2 levels with Person coefficient of 0.66 (p<0.01) in Seoul and of 0.51 (p<0.01) and of 0.33 (p<0.05) in Brisbane, respectively. Using microenvironmental model by time weighted average model, personal NO_2 exposures were estimated with NO_2 measurements in indoor home indoor office and outdoor home. Estimated NO_2 measurements were significantly correlated with measured personal Exposures (r = 0.69, p<0.001) in Seoul and in Brisbane (r = 0.66, p<0.001), respectively. Difference between measured and estimated NO_2 exposures by multiple regression analysis was explained that NO_2 levels in near workplace and other outdoors in Seoul (p = 0.023), and in transportation in Brisbane (p = 0.019) affected the personal NO_2 exposures.

Objective : The aim of this study was to evaluate cytotoxic effect of benzoic acid on normal human skin fibroblast cell line , Detroit 551. Methods : The cytotoxicity was determined by colorimetric assays such as MTT assay or XTT assay. The microscopy was carried out to observe Detroit 551 cell line. Cells were incubated with various concentrations of benzoic acid in CQ incubator controlled with 37 c for 48 hours. Results : The cytotoxic effect of benzoic acid on Detroit 551 did not show a positive significance at 50 uM and 100 uM benzoic acid by MTT assay or X T T assay compared with control. MTTB and XTTg were 900.6 uM and 974.6 uM, respectively. In microscopic study, Detroit 551 treated with benzoic acid showed a slightly decreased cell number, while the morphological changes of cell was not showed.

Volatile organic compounds (VOCs) are present in essentially all natural and synthetic materials from petrol to flowers. In this study, indoor and outdoor VOCs concentrations of houses, offices and internet-cafes were measured and compared simultaneously with personal exposures of each 50 participants in Asan and Seoul, respectively. Also, factors that influence personal VOCs exposure were statistically analyzed using questionnaires in relation to house characteristics, time activities, and health effects. All VOCs concentrations were measured by OVM passive samplers (3M) and analyzed with GC/MS. Target pollutants among VOCs were Toluene, o-Xylene, m/p-Xylene, Ethylbenzene, MIBK, n-Octane, Styrene, Trichloroethylene, and 1,2-Dichlorobenzene. Indoor and outdoor VOCs concentrations measured in Seoul were significantly higher than those in Asan except Ethylbenzene. Residential indoor/outdoor (I/O) ratios for all target compounds ranged from 0.94 to 1.51 and I/O ratios of Asan were a little higher than those of Seoul. Relationship between personal VOCs exposure, and indoor and outdoor VOCs concentrations suggested that time-activity pattern could affect the high exposure to air pollutant. Factors that influence indoor VOCs level and personal exposure with regard to house characteristics in houses were building age, inside smoking and house type. In addition insecticide and cosmetics interestingly affected the VOCs personal exposure. Higher exposure to VOCs might be caused to be exciting increase and memory reduction, considering the relationship between measured VOCs concentrations and questionnaire (p<0.05).

Recent epidemiologic studies revealed that the concentration of air pollutants and fine particulated matter have some effects on health status and are associated with increased mortality and morbidity. The purpose of this study was to characterize background mass concentration of fine particle (PM2.5) and metallic composition from September 2001 to August 2002 in comparison with a medium city, Asan and metropolitan city, Seoul. Conclusively, proper management for fine particles was required in a medium city, Asan, considering the concentrations of metallic elements in fine particles in Asan were relatively higher than those in Seoul. The results were as followed. 1. Average mass concentrations of fine particles in Asan and Seoul were 37.70(±18.41 ㎍/㎥) and 5.83(±38.50)㎍/㎥, respectively. When the weather conditions were classified as normal and yellow-sand, measured average mass concentrations of fine particles in yellow-sand weather condition was significantly higher than those of normal weather condition in both cities (p<0.05). 2. Depending on seasons, measured average mass concentrations of fine particles in Asan and Seoul in spring were 47.76(±19.07) ㎍/㎥m and 61.53 (±4.37) ㎍/㎥, respectively. In summer, the average mass concentrations of fine particles in Asan and Seoul were 29.44(±9.85) ㎍/㎥ and 25.42(±8.10) ㎍/㎥, respectively. Especially, the concentration was the highest in spring and the lowest in summer among four seasons. 3. Average concentrations of manganese(Mn), iron(Fe), chromium(Cr), cadmium(Cd), lead(Pb) and silicon(Si) in fine particles in Asan were significantly higher in Seoul (p<0.05). Average concentration of Si in fine particle in Asan was statistically higher than that of Seoul during yellow-sand condition (p<0.05). 4. Considering the characterization of four seasons, average Pb concentration of fine particle in Asan is significantly higher than that of Seoul in spring(p<0.01). In summer, average Mn and Cr concentrations of fine particle in Asan is higher than those of Seoul (p<0.05). Average Mn. Fe. Cr and Si concentrations in fall (p<0.05), and average Mn, Fe, Cr, Pb, and Si concentrations in winter (p<0.05) in Asan were higher than those of Seoul, respectil'ely. 5. Mass concentrations of each Mn, Fe, Cd and Si in fine particles were significantly correlated with both cities. In normal weather condition, Mn, Cu and Si concentrations are statistically significant in Asan, while Mn, Fe, Cu and Si concentrations are statistically significant in Seoul. Mn, Fe and Si concentrations in both cities were statistically significant during yellow-sand weather.
