Sister-Chromatid Exchanges in Lymphocytes of Medical Students Exposed to Formaldehyde: Soo Jin Lee, Jeong Il Son, Sang Hyo Sim, Kee Young Kim, Jaecheol Song, Suo Ja Chu, Sung Han Shim, Youl Hee Cho, Doo Jin Park; Korean Journal of Occupational and Environmental Medicine 1998;10(2):282-289. Published online May 31, 1998; DOI: https://doi.org/10.35371/kjoem.1998.10.2.282

Sister-chromatic exchanges measured in the peripheral lymphocytes of 15 non-smoking medical students after exposure to formaldehyde during a 24-week anatomy class showed a small but significant (p=0.0468) increase when compared with samples obtained from the same individuals immediately before exposure. Mean frequencies of sister-chromatic exchange of cultured peripheral lymphocytes were 5.40+/-0.24 from the samples before exposure and 5.87+/-0.22 from the same samples after exposure. Breathing-zone air samples collected by formaldehyde monitoring kit with digital colorimeter (SKC) showed a mean concentration of 0.72+/-0.02 ppm formaldehyde.

Abstract PDF

The purpose of this study is to investigate the relationship between the self-reported musculoskeletal symptoms and related factors among VDT operators in bank. The subjects were 950 women workers. The characteristics of subjects were 26.6 years of average age, 5.7 years of average VDT use duration and 6.5 hours of daily VDT use time. The results were as follows. The prevalence of self-reported musculoskeletal symptoms more than severe in Likert scale were 51.4%, 43.9% at the shoulder, 38.3%, 31.8% at the lower back, 38.0%, 31.3% at the neck, 31.2%, 25.2% at the upper back, 21.7%, 16.5% at the wrist and 13.6%, 8.8% at the fingers (while on duty, after home-coming). General characteristic variables affecting the musculoskeletal symptoms were married, number of child and daily house-working time. Work-related factors affecting the musculoskeletal symptoms were VDT working career, daily working time, daily VDF use time, VDF use time without rest, daily work-load and regular rest. As the result of the multiple logistic regression analysis, daily working time, daily VDT use time and VDT working career were significant variables accounting for the musculoskeletal symptoms.

Effect of Benzoic Acid Containing Foods on the Urinary Hippuric Acid Concentration in Workers Exposed to Toluene: Sang Hyo Sim, Jeong Il Park, Jeong Il Son; Korean Journal of Occupational and Environmental Medicine 1996;8(3):526-534. Published online December 31, 1996; DOI: https://doi.org/10.35371/kjoem.1996.8.3.526

Abstract PDF

This Study was performed to investigate the effect of foods containing benzoic acid on the urinary hippuric acid concentration in the toluene exposed workers. The urinary hippuric acid concentration were measured at 0, 30, 60, 90, 120, and 150 minute after intake of soft drink and bread containing benzoic .acid: in volunteers,: who did not have been exposed toluene occupationally. After that urinary hippuric: acids also were measured at the end of shift in toluene exposed workers. And also the concentration of toluene in air were analysed! by gas chromatography. So the relationships between urinary hippuric acid concentration and age, work duration, concentration of toluene in air and intake of benzoic acid containing food were observed. The results were as follows: 1. The urinary hippuric acid concentration reached the highest level at 30 minute after intake of soft drink with bread at a level of 1.41g/g creatinine and soft drink; alone at a level of 1.04g/g creatinine which contained benzoic acid among unexposed toluene, and then gradually decreased. 2. In toluene exposed group no significant effect of general; characteristics siich; as gender, age, work duration, drinking and smoking on urinary: hippuric acid concentration was showed in toluene exposed group. 3. The mean value of urinary hippuric acid concentration of group taking benzoic acid containing foods was significantly higher than that of group not taking. 4. Multiple regression analysis showed that toluene concentration in .air and benzoic acid containing foods were together significantly influence on urinary ; hippuric acid concentration. And the function between variables is Y = 0.014Tpluene +0.489Benzoic acid +0.745 and the contribution rates were 31%. In conclusion, it was suggested that the information on intake of benzoic acid containing foods should be considered in measurement of urinary hippuric acid for the more accurate toluene exposure evaluation.
