Background: Ginseng (Panax ginseng Meyer) is an important medicinal herbs in Asia. However, ginsengvarieties are less developed. Method: To developed ginseng varieties, a pure line selection method was applied in this study. Results: Gumpoong was testing of 4-yr-old specimens in 2002, the proportions of the below-groundroots that were rusty colored for Gumpoong was 1.29 in Daejeon and 1.45 in Eumseong, whereas theproportions for its yellow berry variant were 2.60 and 2.45 in the two regions, respectively. Thus theGumpoong was resistant to root rust. Sunpoong has a high yielding property. Its average root weight is70.6 g for 6-yr-old roots. Its yield is 2.9 kg/1.62m2 and the rate of heaven- and earth-grade product is20.9%, which is very high compared to 9.4% for Yunpoong. Sunone is resistance to root rot and thesurvival rate of 4-yr-old roots was 44.4% in 1997, whereas that of the violet-stem variant landrace was21.7%. Sunhyang has content of arginyl-fructosyl-glucose (AFG), which produces the unique scent of redginseng, is 95.1 mmol/g and greater than the 30.8 mmol/g of Chunpoong in 6-yr-old plants. Sunun andCheongsun are being nurtured to protect genetic resources. Conclusion: Developed ginsneg varieties will be used as the basis for the protection of genetic resourcesand breeding. Jang-Ho Lee

권장혁,박기태 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.3

Rabson Mendenhall syndrome은 Rabson과 Mendenhall에 의해 1955년 처음 발표된 증후군으로서, 심한 insulin resistance를 보이는 희귀한 상염색체 열성 유전성 질환이다. Insulin receptor의 돌연변이나 insulin이 작용하는 다른 target cell의 결함에 의해 나타나며, 일반적인 증상으로는 흑색가시세포종(acanthosis nigricans), 다모증(hypertrichosis), 손발톱 비대 (onychauxis), 성장 지체 (growth retardation), 성 조숙(precocious puberty), 생식기의 비대, 팽만된 복부(protuberant abdomen), 건성 피부(xerotic skin) 등이 나타난다. 악안면 영역에서는 치아의 이형성, 거친 얼굴의 피부, 하악 전돌, 균열 혀 (fissured tongue)와 같은 특징적 증상이 나타난다. 이에 본 증례에서는 Rabson Mendenhall syndrome으로 본원에 내원한 4세 환아에게 관찰된 치과적 특징들에 관하여 보고하는 바이다. Rabson-Mendenhall syndrome(RMS) is first characterized in 1955 by Rabson and btendenhall. RMS is a rare autosomal recessive variant with insulin resistance. This is due to insulin receptor mutations or other target-cell defects in insulin action. General findings include acanthosis nigricans, hypertrichosis, onychauxis, growth retardation, precocious puberty genital enlargement, protuberant abdomen and xerotic skin. Characteristic oral and maxillofacial findings include dental dysplasia, coarse facial skin, prognathic jaw and fissured tongue. In this case report, dental characteristics of a 4-year old boy with Rabson-Mendenhall syndrome are described.

목적: PFOA에 노출이 가능한 제조업 근로자들을 대상으로 혈청 PFOA농도를 조사하고 생활습관, 직업적 요인, 간기능 및 혈청 지질과의 관련성을 연구하고자 하였다. 방법: 2007년 8월부터 12월까지 부산지역 1개 대학병원 산업의학과에서 건강진단을 받은 PFOA노출 가능성이 있는 제조업 사업장 근로자 남자 203명과 여자112명의 총315명을 대상으로 하였다. 생활습관 및 직업적 요인을 설문조사 하였고, 혈청 PFOA 농도를 LC-MS/MS로 분석하였으며, 간기능 및 혈청 지질 검사를 실시하였다. 결과: 혈청 PFOA 농도의 평균은 전체가 8.0 ng/mL이었으며, 남자가 9.0 ng/mL, 여자가 6.3 ng/mL로 남자가 여자보다 통계적으로 유의하게 높았다(p<0.001). 다중회귀분석을 시행한 결과 성, 연령, 체질량지수, 총 콜레스테롤 등이 유의하게 나타났으며, 성별로는 남성에서, 연령이 많을 수록, 총 콜레스테롤이 높을 수록, 체질량지수가 낮을 수록 혈청 PFOA의 농도가 통계적으로 유의하게 높았다. 로지스틱 회귀분석을 실시하여 성과 연령을 보정한 교차비를 산출한 결과, 섬유제품 염색, 정리 및 마무리 가공업(OR 6.16)이 통계적으로 유의하게 높았고, 주형 및 금형 제조업(OR 4.84), 선박 구성부분품 제조업 (OR 3.87), 플라스틱 합성피혁 제조업 (OR 10.05) 등이 상대적으로 높았다. 결론: 제조업 근로자들의 혈청 PFOA 농도는 성, 연령 및 총 콜레스테를 등과 관련성이 있었고, 업종별로는 섬유제품 염색, 정리 및 마무리 가공업에서 높은 것으로 조사되었다. 이러한 결과는 PFOA의 인체 위해성을 조사하기 위한 기초자료로 활용가치가 있을 것이다. Objectives: The objective of this study was to determine serum perfluorooctanoic acid (PFOA) concentrations and to investigate the relationship of lifestyle, health status and work-related factors among workers at manufacturing companies with possible occupational exposure to PFOA. Methods: The study subjects were 315 workers (male 203, female 112) of manufacturing companies with possible exposure to PFOA from August to December, 2007. A questionnaire was administered to investigate lifestyle and work-related factors. Serum PFOA concentrations were analyzed by LC-MS/MS, and liver function and total cholesterol were also tested. Results: Serum PFOA concentrations ranged from 1.0 to 40.9 ng/mL (mean 8.0 ng/mL). Serum PFOA concentrations increased with age. Male workers had higher PFOA concentration than female workers (male 9.0 ng/mL; female 6.3 ng/mL). According to stepwise multiple regression analysis, factors significantly associated with PFOA concentration were male, being older, higher total cholesterol, and lower body mass index. Adjusted for age and gender by logistic regression, dyeing and finishing textiles had significantly higher odds ratio (OR) of 6.16, and moulding patterns, moulds and industrial patterns (OR=4.84), sections for ships (OR=3.87), and plastics synthetic leather (OR=1O.05) had marginally significantly high odds ratios. Conclusions: This study demonstrated the factors affecting serum PFOA concentration of workers at manufacturing companies. Further study is needed to ensure the effect of occupational exposure on serum PFOA concentration.

元章喜,權昌鎬 慶熙大學校 1984 論文集 Vol.13 No.-

The drug metabolism of several antituberculosis was investigated in liver injuried rabbits. Antituberculosis drugs which used on this experiment were Rifampicin, Isoniazide and Pyrazinamide. The results were as follows. 1. Activities of sGOT and sGPT of rabbits induced liver injury by CCl_4 were increased (in sGOT, from 48.9 ± 1.48 units/ml to 370 ± 19 units/ml and in sGPT, from 42.5 ± 1.22 units/ml to 386 ± 32 units/ml) after the lapse of 24 hours from CCl_4 administration and then they were decreased gradually with the lapse of time (in sGOT, to 310 ± 25 units/ml and in sGPT, to 285 ± 26 units/ml after the lapse of 72 hours from CCl_4 administration). 2. The rifampicin which cxcreted mainly through bile at a small dose administration was excreted in urine at a large dose administration. 3. Each antituberculosis drugs which administrated on this experiment was excreted more quantity in urine of CCl_4 pretreated rabbits as compared with normal rabbits. particularly, Rifampicin was excreted far more quantity in urine of CCl_4 pretreated rabbits all the time. 4. From the above results, it was recognized that many notice about use of Antituberculosis drugs to liver injuried body must be required.
