임영,한진구,김지홍,김현욱,김은경,김경아,장황신 大韓産業醫學會 1999 대한직업환경의학회지 Vol.11 No.3

Objectives : This study was designed to evaluate cytotoxicity of TAFMAG, which is a trade name of natural mineral fiber mined and produced in China. Methods : The cytotoxicity of TAFMAG was evaluated by measuring iron content, lipid peroxidation, erythrocyte hemolysis, and cytotoxicity in vitro. These results were compared with the data of chrystotile and wollastonite as a positive and negative control, respectively. Results : There was significant increase of Fenton activity in TAFMAG and chrysotile with dose-response pattern. The iron chelating agent, desferrioxamine, significantly decreased Fenton activity of the particulates except wollastonite. TAFMAG and chrysotile fibers significantly increased malondialdehyde concentration from lipid peroxidation of the red blood cell membrane. In erythrocyte hemolysis test, TAFMAG & chrysotile had stronger effect on erythrocyte hemolysis than wollastonite with the concentration of 1,000g/ml. Furthermore, TAFMAG was more hemolytic than chrysotile with the concentration of 5,000g/ml. There was a significant cytotoxic effect in TAFMAG and chrysotile on RAW cell compared with wollastonite. Conclusions : In vitro study suggested that TAFMAG may have a similar health hazard as usual asbestos.

Vitamin D and carotid subclinical atherosclerosis in SLE Chang-Bum Bae, Ju-Yang Jung, Bo-ram Go, Hyun-Ah Kim, Chang-Hee Suh Department of Rheumatology, Ajou University School of Medicine, Suwon, Korea Introduction Atherosclerosis develops earlier in systemic lupus erythematosus (SLE) and is the important cause of mortality. It has been suggested that vitamin D deficiency contributed cardiovascular disease and immune dysregulation in SLE. Methods One-hundred two female patients with SLE and 52 normal controls (NC) were recruited. The carotid artery intima-media thickness (cIMT) and plague were assessed by B-mode ultrasound at the carotid artery level. Vitamin 25(OH)D3 levels were checked by immunoradiometric assay using the Bio-Line 25(OH)D3-Ria CT kit (Bio-Line S.A., Belgium). Disease activity markers were checked at the time of enrollment. Results The cIMT of SLE is 0.41±0.08mm, which is higher than NC (0.37±0.11 mm, p=0.012). Also, carotid artery plague index (PI) of SLE is higher than NC (0.68±1.39 vs 0.26±0.87, p=0.026). The cIMT was correlated with age (r=0.442, p<0.001), body mass index (r=0.246, p=0.013), waist-hip ratio (r=0.245, p=0.013), SLE disease activity index (r=0.239, p=0.016), taking aspirin (r=0.244, p=0.013), and the carotid artery PI was correlated with renal involvement (r=0.224, p=0.023) in patients with SLE. Vitamin 25(OH)D3 was not showed correlation with cIMT and carotid artery PI. Also, it was not correlated with disease activity markers. Conclusion In patients with SLE, the risk of cardiovascular disease measured by cIMT and carotid artery plaque was higher than NC, which may be derived from systemic inflammation. However, vitamin D levels were not showed significant correlations with carotid subclinical atherosclerosis. It may be not suitable to assess vitamin D as marker of disease activity or subclinical atherosclerosis.

Objectives : The purpose of study is to assess the clinical characteristics of complicated Meckel's diverticulum in children. Methods : A retrospective review of pediatric cases of complicated Meckel's diverticulae that were surgically treated at Ewha Womans University Hospital from 1985 was performed. The charts were reviewed for the age and sex of the patients, operation finding, treatment, and outcome. Results : A total 13 patients with a complicated Meckel's diverticulum were identified. There were 8 boys(61.5%) and 5 girls (38.5%) with a mean age of 5.3 years (range, 1month to 14years). Presenting signs and symptoms included digestive hemorrhage (6), intestinal obstruction(4), perfora-tion (1), intussusception due to inverted Meckel's diverticulum (1) and diverticulitis (1). A ^(99m) technetium pertechnetate scintiscan was positive in 3 of 4 patients. Barium contrast studies and colonoscopys were not diagnostic. The mean distance from the ileocecal valve to the diverticulum was 47.0±15.7cm. Average length of the diverticulum was approximately 4.7±3.0cm. Segmen-tal small bowel resection including Meckel's diverticulum (84.6%) or wedge excision(15.4%) was done for treatment. In the bleeding group, ectopic gastric mucosa was present in 5 of 6 patients. Postoperative morbidity and mortality was each 0%. Conclusion : The results of this study draw attention to the fact that the complicated Meckel's diverticulum must be suspected in children with acute abdomen or gastrointestinal bleeding. 목적: Meckel 게실의 합병증의 원인이 되어 수술적 치료를 받은 소아 환자들의 임상적 증상과 수술소견, 병리학적 소견을 분석하여 이들의 특징을 알아보고자 하였다. 방법 : 1985년 이후 이화대학교의료원에서 Meckel 게실의 합병증으로 수술을 받은 15세 이하의 소아들 대상으로 하여 의무기록과 조직병리 검사 결과를 조사하였다. 결과: 총 13명의 환아가 Meckel 게실의 합병증으로 수술을 받았으며 남녀의 비는 1.6:1로 남아에서 호발하는 경향을 보였으며, 수술 시 평균 연령은 5.3세였다. 수술의 원인이 된 Meckel 게실의 진단은 장출혈 6예, 장폐색 4예,Meckel 게실의 천공 1예, 장중첩 1예, 게실염 1예였다. 회맹판에서 게실까지의 평균길이는 47.0±15.7cm이었으며, 소장부분절제술과 쐐기절제술이 각각 84.6%와 15.4%에서 시행되었다. 장출혈을 나타내었던 환아 6명 중 5예에서 병리조직에서 이소성 위 점막이 관찰되었다. 술 후 합병증과 사망예는 없었다. 결론 : 소아에서 외과적 급성 복증이나 장출혈의 증상이 나타날 경우, Meckel 게실의 합병증의 가능성에 대한 외과의의 인식이 필요하다.

This study was designed to estimate particle size distribution of airborne dust by an 8-stage cascade impactor, to compare concentrations of total dust by 37mm closed-face cassette with total dust, thoracic particle mass(TPM), inhalable particle mass(IPM) concentrations by an 8-stage cascade impactor and to estimate concentrations of respirable dust collected by cyclone in manufacturing factories. Total 85 sites in 44 factories were sampled from August 1, 1996 to December 31, 1997. The results were as follows: 1.The geometric mean concentration of total dust collected by 37mm closed-face cassette were 0.27-1.44 mg/㎥. The GM concentrations of total dust by impactor were 0.82-2.85 mg/㎥, of inhalable dust 0.63-2.24 mg/㎥, and of thoracic dust were 0.31-1.40 mg/㎥, respectively. 2.The analysis of particle size distribution showed bimodal patterns for almost all sampling sites studied. Geometric mean(GSD) diameters of the small mode were 0.515(1.577) ㎛ - 3.032(13.698) ㎛, while the large mode were 11.873(2.460) ㎛ - 19.774(2.606) ㎛, respectively. 3.The geometric mean(GSD) concentrations of respirable dust collected by cyclone were 0.08-0.46 mg/㎥. To evaluate health hazards from mineral dusts occurring in manufacturing industries, these results suggest the necessity of promulgating particle size-selective limit values and sampling methods such as IPM, TPM, and RPM.
