양승림 大韓産業醫學會 1994 대한직업환경의학회지 Vol.6 No.2
The author studied the frequencies of sister chromatid exchanges of cultured peripheral lymphocytes from 51 chromium exposed workers and 29 controls in order to examine the inductivity of sister chromatid exchanges of cultured peripheral lymphocytes of chromium exposed workers, from June 1989 to March 1990. The results obtained were as follows: 1. Mean frequencies of sister chromatid exchanges of cultured peripheral lymphocytes were 9.33±2.57 from chromium exposed workers and 7.59±0.81 from control, respectively, and the former was significantly higher then the latter(p<0.01). 2. The frequencies of sister chromatid exchanges of cultured peripheral lymphocytes by duration of employment from chromium exposed workers was increased in proportion to that, but there was no statistical significance. 3. The frequencies of sister chromatid exchanges of cultured peripheral lymphocytes by chromium concentration in blood and urine of chromium exposed workers were not significantly increased. 4. The frequencies of sister chromatid exchanges of cultured peripheral lymphocytes by levels of alcohol consumption in chromium exposed workers was inclined to increase in proportion to that. 5. The frequencies of sister chromatid exchanges of cultured peripheral lymphocytes by number of cigarettes smoked was significantly increased in proportion to that in both chromium exposed workers and controls(p<0.05). 6. In drinkers of chromium exposed workers, the frequencies of sister chromatid exchanges of cultured peripheral lymphocytes in smokers was higher than nonsmokers, but there was no statistical significance.
인체의 장기조직중 Dieldrin의 잔류량에 관한 조사
양승림,정갑열 부산대학교 환경문제 연구소 1986 環境硏究報 Vol.4 No.-
Dieldrin is belongs to the organochlorine pesticide compounds, but it's pharmacodynamic action and metabolic mechanism are different to the other organochlorine compounds. So this study was conducted to investigate the amounts of dieldrin residues in human organ tissues of 52 autopsy cases which were caried out in Pusan and Kyung-nam area. The obtained results were as follows; 1. The residues of dieldrin in each tissue were 20.19±14.97ppb in liver, 10.37±6.84ppb in kidney, 14.79±8.67ppb in heart, 3.27±1.98ppb in lung and 12.21±7.25ppb in pancreas. 2. Although there was no statistical significance, the values of dieldrin residues in male were generally higher than in female. 3. The residues of dieldrin in all tissues were showed increasing tendency with the age. 4. The frequency distribution type of dieldrin residues in liver and kidney showed as like "L" type, right-skewed distributed type in heart and pancreas and irregular pattern in lung tissue.
