The selective absorption ability of low density heavy metal(Pb(Ⅱ) ion or Cu(Ⅱ) ion) of eggshell(raw or boiled) is better than one of existing absorption materials in treatment ability and experimental condition. The elimination ability of chlorine of eggshell(raw or soiled) is worse than one of active carbon. In elimination of trihalomethane, the effect of treatment of eggshell is almost the same as one of pine cones. And surface of eggshell(raw or boiled) after absorption of heavy metal ion was observed by Scanning Electron Microscope(SEM). Application and availability of eggshell(raw or boiled) as absorption material need lots of experiments. The experiment on baked eggshell is proceeding.

노인성 치매의 일종인 alzheimer's disease의 효과적인 억제제를 합성하기 위해 우리는 분자 모델링에 의한 가장 적합한 물질인 m-[(N,N,N-trimethylammonio)phenyl]boronic acid를 합성하였다. 출발물질인 3-aminophenylboronic acid monohydrate의 경우 boronic acid의 작용기인 hydroxyl group을 protecting시킴으로써 반응의 안정성을 기하였다. Quarternary ammonium salt는 과량의 methyliodide와 염기 촉매인 potassium hydrogen carbonate를 사용하여 용매인 methanol에서 반응시켜 상당히 높은 수율을 얻을 수 있었다. 또한 과량의 methyliodide와 염기촉매인 potassium hydrogen carbonate를 사용하여 용매인 methanol에서 반응시킨 결과 boronic acid의 protection없이도 안정하게 반응이 진행되어짐을 확인할 수 있었다. In order to syntheisize a effective inhibotor for alzheimer's disease, we synthesized m-[(N,N,N-trimethylammonio)phenyl]boronic acid 4 which is designed by molecular modeling form. We protected the hydroxyl group of 3-aminophenylboronic acid monohydrate 1 with ethlyne glycol to remove the reactivity if hydroxyl group. To synthesize m-[(N,N,N-trimethylammonio)phenyl]boronic acid 4, we reacted 3-aminophenylboronic acid monohydrate 1 with ezcess methyl iodide and potassium hydrogen carbonate as a base-catalyst in methanol. but On executed reaction without protection on hydroxyl group, we found out the result that the hydroxyl group of boronic acid group at 3-aminophenylboronic acid monohydrate 1 didn't react with excess methyliodide. Synthesized m-[(N,N,N-trimethylammonio)phenyl]boronic acid 4 is in progress about biological tests as a plausible acetylcholinesterase inhibitor.

Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

최윤정,방승규,김정진,도규영,백인호 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.4

연구목적 : 도파민계는 알코올 추구와 같은 알코올 의존증과 관련된 행동에 중요한 역할을 한다. Dopamine transporter(DAT1)는 신경연접부위에서 도파민 재흡수에 관여하여 도파민 활성을 종결시키는 물질로 알려져 있다. 그러므로, DAT1 유전자가 알코올 의존증에 대한 감수성에 영향을 줄 수 있다. DAT1 유전자는 다형성을 보이는 반복된 40개의 염기서열(VNTR)을 갖는다. 본 연구에서는 DAT1 유전자 다형성과 알코올 의존증 및 알코올 의존증의 임상변인과의 관련성에 대하여 알아보았다. 방 법 : 알코올 의존증 환자 94명과 정상대조군 113명을 대상으로 말초혈액을 채취하여 분리된 DNA의 DAT1 유전자를 DNA 중합효소연쇄반응으로 증폭하였다. 증폭된 산물을 15% polyacrylamide gel에서 전기영동하여 나타나는 띠의 크기에 따라 유전자형을 구분하였다. 자료의 통계적 처리는 Fisher's exact test, oneway ANOVA를 사용하였다. 결 과 : 환자군과 정상대조군의 유전자형은 모두 Hardy-Weinberg equilibrium의 예상치와 유의한 차이가 없었다. 대립유전자는 7 repeats, 9 repeats, 10 repeats, 11 repeats의 4가지 종류로 구분되었고, 유전자형은 7/7 repeats, 7/10 repeats, 9/10 repeats, 10/10 repeats, 10/11 repeats의 5가지 형태를 보였다. 환자군과 대조군간에 DAT1 유전자형 및 대립유전자 빈도는 유의한 차이가 없었고, DAT1 유전자형에 따른 음주 시작 연령, 알코올 의존증의 발병 연령 및 잠복기간에서도 차이가 없었다. 알코올 의존증의 가족력이 있는 환자군과 없는 환자군은 DAT1 유전자형의 빈도에서 차이가 있는 경향을 보였고(χ²=6.912, p=0.081), DAT1 대립유전자의 빈도에서도 유의한 차이가 있었으며(χ²=10.193, p=0.008), lambda값은 0.046였다. 결 론 : DAT1 유전자의 다형성이 알코올 의존증의 유전적 소인이 될 가능성은 적은 것으로 보이나, 알코올 의존증의 가족내 유전과는 관련있을 것으로 시사된다. Objectives : Alcoholism is known to be a heritable disease. It has been hypothesized that dopaminergic systems play an important heritable role in human behavor related to alcohol dependence, such as alcohol seeking. Therefore, genes involved in this pathway, including dopamine transporter(DAT1), which is responsible for taking released dopamine back up into presynaptic terminals and terminating dopaminergic activity, are potential candidate that may affect susceptibility to alcoholism. Analysis of a 40-base pair(bp) repeat(VNTR) in the 3' untranslated region of the DAT1 gene revealed variable number of the repeat ranging from 3 to 11 copies. Therefore, in the present study, we examined the association between alcoholism and VNTR polymorphism of DAT1. Methods : Genomic DNA analysis with polymerase chain reaction(PCR) was used to identify the presence of a VNTR polymorphism. It was carried out within a group of 94 alcoholic patients and 113 normal controls. Results : 1) There were no significant differences in allelic or genotype frequencies between the group of alcoholic patients and controls. 2) There were no significant differences in the first drinking age, onset age and latency of alcoholism according to DAT1 genotypes. 3) There was a significant difference in allelic frequencies between alcoholics with family history and those without family history. Conclusions : These results suggested that VNTR polymorphism of DAT1 is unlikely to be a factor in the genetic etiology of alcoholism, but might be related to familial transmission of alcoholism.
