In this study, we measured the activity of the erythrocyte pyrimidin 5'-nuclectidase(P5N) and urinary N-acetyl-β-D-glucosaminidase(NAG) from 154 workers exposed to lead and 43 workers not exposed. We analyzed the correlation of the P5N activity and NAG activity with other biololgical exposure indices of lead such as blood lead(PbB) and zinc protoporphyrin(ZPP). The measurement was performed by using high performance liquid chromatography(HPLC), spectrophotometer and atomic absorption spectrophotometer. The results are as follows : 1. The mean value of P5N activity for workers exposed to lead was 9.50±3.13 μmol uridine/hr/g Hb and 11.60±2.2 μmol uridine/hr/g Hb for workers not exposed. The P5N activity showed a normal distribution, but the other indices of lead showed logarithmic normal distributions. 2. The P5N activity and ZPP were decreased as PbB was increased. But the NAG activity had no correlation with changes of PbB. 3. The correlation coefficients of the P5N activity with other biological exposure indices of lead such as PbB, ZPP, NAG activity were -0.72, -0.55, and 0.05, respectively. We speculated that the P5N activity can be used as a reliable biological exposure index of lead but NAG activity can be used as a biological management index of lead.

In 2007, the Korean Society of Infectious Diseases recommended an immunization schedule for adults residing in Korea. This recommendation includes four categories: standard immunization for healthy persons, supplementary immunization for persons with underlying illnesses, recommendations for health-care personnel and for international travelers. The Standard Immunization Schedule consists of universal vaccination (tetanus-diphtheria/tetanus-diphtheria-pertussis (Td/Tdap); hepatitis A vaccine for persons aged 20s; human papilloma virus vaccine for women under 26 years old; meningococcal vaccine for military recruits and college students in dormitories; influenza vaccination for persons aged 50 years or more and pregnant women; and pneumococcal vaccination for persons aged 65 years or more) and catch-up vaccination (hepatitis A vaccine for persons aged 30s; hepatitis B vaccine, varicella and MMR vaccines for persons who have uncertain specific immunities). The Supplementary Immunization Schedule recommends 4 vaccines, i.e., pneumococcal, influenza, meningococcal, and Haemophilus influenzae type b, appropriate to the underlying illnesses, and confirmation of the presence of antibodies to hepatitis A and hepatitis B. The Recommendation for Health-Care Personnel includes universal vaccination (influenza and pertussis) and catch-up vaccination (hepatitis B, measles-mumps-rubella and varicella for seronegative health-care personnel). The Recommended Immunization for International Travelers focuses reinforcement of vaccinations for healthy persons and includes certain immunizations necessary for international travel (yellow fever, meningococcal, plaque, tick-borne encephalitis, and cholera). These guidelines can be seen at www.ksid.or.kr.

이광학,문광호,김영홍,최욱태 울산대학교 1995 공학연구논문집 Vol.26 No.2

LiMCA방법으로 아연 용탕내에 Pb를 첨가하여 불순물의 입자크기를 측정하였다. 아연 용탕내에 Pb의 첨가량이 증가할수록 불순물의 수는 증가하였으며 불순물의 입자 분포는 일정범위를 크게 벗어나지 않고 d=50㎛이하의 입자직경이 약90% 이상 존재하였다. 실험 후 시편을 분석한 결과, 시편내에 미량의 ZnO와 PbO가 존재함을 확인하였으며, 이는 아연용탕 내에서 제 2상의 거동을 예상하고 첨가한 Pb에 의해 형성된 PbO와 극소량의 ZnO등이 불순물로 거동한 것으로 사료된다. 본 실험은 약1분 정도의 짧은 시간으로 수행되었으며, 실험결과 사용된 장치의 감지 한계는 불순물의 입자직경이 d=29㎛이었다. The particle size of impurities was measured with addition to Pb in the molten Zinc by using LiMCA method. The number of impurities was increased with increasing Pb addition in the molten Zinc and particle size distribution of impurities was not deviated from the constant range therefore the particle size, d=50㎛ existed about 90% in this study. The experimental results of X-ray analysis, it was found that the small amount of PbO and ZnO which are formed with Pb addition to the molten Zinc, expecting the second particle role, behavior as impurities. This study was carried out about one minute and the detect limit of particle size of impurities using instrument was obtained d=29㎛.

신시옥,송창근,이동욱,최영석,진흥률,신정우,윤희석 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.1

연구목적: 이성대상포진에 동반되는 안면신경마비는 Bell's palsy와는 달리 예후가 더 나쁘고 그 마비가 완전히 회복되지 않는 경우가 더 많다.본 연구에서는 이성대상포진에서 발현되는 증상들의 유무가 치료 전 안면신경마비의 정도 및 치료 후 예후와 상관관계가 있는지를 관찰하여 예후의 예측인자에 대해 분석하였다. 재료 및 방법: 지난 1992년 1월부터 1999년 6월까지 이성대상포진으로 진단받고 본원에 입원하여 고용량 부신피질호르몬제와 항바이러스제인 acyclovir의 병합투여로 동일한 치료를 받은 30명의 환자를 대상으로 후향적으로 의무기록을 분석 및 고찰하였으며, 치료 전 안면마비의 정도와 치료 후 마비의 회복 정도를 이통, 이명, 난청, 현훈 등의 증상의 유무와 치료 시작 시기, 그리고 안면신경의 electroneuronography(ENoG) 값에 따라 비교하였다. 결과: 이성대상포진수포가 안면신경마비 보다 먼저 발현된 경우에 안면신경마비의 치료 전 grade가 통계적으로 유의하게 좋았다(p<0.05).이통, 청력손실, 그리고 현훈의 유무에 따른 안면신경마비의 정도는 상관관계가 없었고 예후에도 차이가 없었다.이명의 유무에 따른 치료 전 안면신경마비의 정도는 상관관계가 없었으나 치료 후 완전회복율은 이명이 있었던 군에서 통계적으로 유의하게 높았다(p=0.003<0.05).완전회복군과 불완전회복군 사이의 치료 전 ENoG의 수치는 통계적으로 유의하게 예후와 상관이 있었다(p=0.037<0.05). 결론: 좀더 많은 수의 환자를 연구에 포함하여 증상에 따른 예후의 차이를 연구하는 것이 필 요하며 또한 ENoG 값이 10%에서 40% 사이인 환자들의 치료 방법에 대한 고려와 이성대상포진수포가 안면신경마비보다 먼저 생긴 환자에서 치료 전 마비정도가 경미했던 이유에 대한 연구가 필요할 것으로 생각된다. Purpose: Herpes zoster oticus generally has a poor prognosis, leaving many patients with permanent facial nerve dysfunction, compare to Bell's palsy.Acyclovir and prednisolone have been widely used for the treatment of herpes zoster oticus.This retrospective study was conducted to suggest the prognostic factors according to various symptoms. Materials and Methods : Clinical studies were retrospectively performed on 30 patients with herpes zoster oticus who were treated with acyclovir and prednisolone in the Chungbuk National University Hospital between 1991 and 1999.The authors analyze the pre-treatment grade and prognosis of facial nerve palsy according to symptoms(the existence of otalgia, tinnitus, hearing loss, and vertigo), the treatment onset, and electroneuronography ( ENoG ). Results : Of thirty patients who have been diagnosed as herpes zoster oticus, there is no significant difference in the pre-treatment grade of facial nerve palsy according to the existence of vesicle, otalgia, tinnitus, vertigo, and hearing loss.Of 25 patients who have facial nerve palsy, the recovery from the palsy is complete in 14 patients(56%).There is no significant difference in the pre-treatment grade of facial nerve palsy according to the existence of otalgia, tinnitus, vertigo, and hearing loss.The pre-treatment grade of facial palsy is better when the vesicles precede facial in the group with tinnitus than without tinnitus.A significant difference of the prognosis according to the onset of treatment and other symptoms are not found.ENoG is better in the group that facial nerve palsy is completely recovered than incomplete recovery group. Conclusion : Reliable prognostic factor according to symptoms is not found, ENoG is the only prognostic factor.
