A 25 year old woman who suffered muscle pain on both lower extremities and dizziness had taken Chinese herb powder for two months to relieve symptoms. We had carried out cell blood counts including basophilic stippling of red cells, and analyzed the blood lead, urine lead, urine α-aminolevulinic acid and urine coproporphyrine. By the reference of these laboratory findings, clinical manifestations such as severe anemia and lead line on gingiva, she was diagnosed lead poisoning. The chinese herb powder which she had ingested daily a pack weighted 750mg had contained 5mg lead corresponding 7.6% per a pack. After administration of D-penicillamine as a chelating agent for two months, the aboved clinical manifestations and laboratory findings were markedly improved and the therapy are still continued.

본 연구의 목적은 유리섬유를 취급하는 근로자에서 발생 가능한 건강장해의 종류와 유리섬유를 취급하는 근로자의 피부질환의 특성을 파악하고 피부질환의 진단 방법을 개발하는데 있다. 따라서 유리섬유를 직접 취급하는 남성 근로자 40명을 폭로군으로, 유리섬유를 취급하지 않고 폭로군과 같은 사업장에 근무하는 남성 생산직근로자 57명을 비교군으로 선정하여 설문 조사와 단순흉부촬영을 시행하고 피부 병변에서 유리섬유를 관찰하여 다음과 같은 결과를 얻었다. 1. 폭로군에서 통계적으로 유의하게 많이 호소한 자각증상 내용은 '기침이 난다(32.5%)'가 가장 호소율이 높았고, '코가 간지럽다(30.0%)', '눈이 따갑다(27.5%)', '코가 따갑다'(5.0%)', '가래가 많다(225%)'의 순이었다. 2 흉부방사선 촬영의 모든 소견이 폭로군과 비교군에서 통계적으로 유의하지 않았다. 3 유리섬유를 취급하는 근로자의 피부질환의 유병률은 25.0%, 누적 유병률은 75.0%였다. 4. 유리섬유를 취급하는 근로자중에서 피부질환이 발생한 시점은 유리섬유를 취급한지 1개월 미만이 46.7%로 가장 많았고, 피부질환의 발생 부위는 손과 팔이 가장 많았고, 피부 발진은 또 56.7%가 관찰할 수 있다고 응답하였으며, 병의원을 이용하여 피부 가려움증을 치료한 근로자는 6.7%에 불과하였다. 5. 피부 채취 표본을 스카치 테이프와 수산화칼륨을 이용하여 광학 현미경, 면광 현미경 및 위상차 현미경을 이용하여 유리섬유의 존재를 증명함으로써 유리섬유에 의한 피부 가려움증을 진단할 수 있었다. Man-made vitreous fibers(MMVFs) have been used for insulation over 60 years. MMVFs are amorphous silicates with a length-to-diameter ratio greater than 3:1. Fibrous minerals can induce irritation on skin and upper respiratory tract. This study was conducted to evaluate the health risks of glass fiber workers. We examined 40 male glass fiber workers (exposure group) and 57 male workers who do not use glass fiber(comparison group) with questionnaires, physical examination, chest x-ray and pathologic examination. The results were as follows: 1. Most of the clinical symptoms were significantly more frequent among the exposure group than the comparison group. Cough(32.5%), itching of nose(30.0%), irritation of eyes(27.5%), irritation of nose(25.0%), sputum(22.5%) were the major symptoms among exposure group. 2. No case of pneumoconiosis was observed among the exposure group and there was no difference in chest abnormalities between the exposure group with the comparison group. 3. Prevalence of dermatosis among the exposure group was 25.0%(10 cases) and cumulative prevalence was 75.0%(30 cases). 4. Onset of dermatosis among the exposure group was most frequent within one month after dealing (46.7%). The most frequent site of skin lesion was hands(53.3%) and arms(50.0%). Skin eruptions was observed in 17 cases(56.7%) and only two cases(6.7%) were treated at clinic. 5. Glass fiber induced skin lesions could be diagnosed by scotch tape method or KOH mount and examining the specimen under the light, polarizing and phase-contrast microcopies.
