OBJECTIVES: This study is to see the transition and pattern of the industrial iureal worker, and to develop the prediction model. METHODS: The data of the study are based on the samples from data-warehouse of Occupational Safety & Health Research Institute and are summed monthly from Jan 1986 to Dec 1999. This study data used data mart and Meta data from DW in KOSHA. The prediction model of the injured worker in Industry is designed by using a winters time series method after data preparing (i. e. sample, explore, modify) from DW. RESULTS: Thls predicted model obtained Winters-method multiplicative in exponential smoothing among applied all models, after the tlme series (total 163 months). It showed that the prediction power was 95.5 %. CONCLUSIONS: In the process of exploring the data, totally the rate of industrial injureal workers reduced, and in the yearly circulation, in February and September the number is the lowest but in June, July, October and November the higher. The number of monthly average injureal workers is 8709 (95 % confidence interval 8277, 9140). From the developed prediction model, since Aug 1999 the industrial injureal worker reduced rapidly in Dec 1999 and first period of 2000. But In second period of 2000 the number of the injured workers is increasing. To conclude, as the total economic situation is becoming better in 2000 than In 1999, its is supposed that the injured workers will increase more than the predictive injured workers because of the increase of production rate and labor force.

PURPOSE: Ataxia Telangiectasia (AT) is a hereditary multi-systemic disease resulting from mutations of AT gene and is characterized by progressive neurodegeneration, cancer, immune system defects, and hypersensitivity to ionizing radiation. AT gene has a homologue sequence of PI3-kinase. The activity and cellular function of PI3-kinase in AT gene remains unclear. This study was undertaken to evaluate the function of AT gene through the effect on cell survival and differentiation by the inhibition of AT gene expression. MATERIALS AND METHODS: NH2-terminal portion of AT gene was isolated from MCF-7 cells by RT-PCR. The isolated DNA fragment was ligated in reverse orientation in pcDNA3. This antisense ATM expression vector was transfected to PC-12 cells by calcium phosphate method, and the transformed cells were selected using G418 and immunohisto- chemistry. To analyze the cell survival and differentiation, cells were cultured in serum free medium supplemented with/without NGF. We performed the immunoprecipitation for the p53 induction of cells after ionizing radiation, and the FACS for the apoptosis of cells after the exposure of wortmanin. RESULTS: PC-12 cells which down-regulated AT gene (like ATM, AT mutated) showed decreased survival and ceased differentiation with NGF. Also, PC-12 (ATM) cells showed increased apoptosis with wortmanin and reduced or delayed p53 induction after ionizingradiation. CONCLUSION: Results obtained from these studies suggest that AT gene regulates survival and differentiation of PC-12 cells through PI3-kinase activity. It seems that apoptosis is induced by the inhibition of AT gene expression.

BACKGROUNDS: The molecular genetic characteristcs of cis-AB blood group have shown that its allele had C, G, C and C at nucleotide positions (nps) 526, 703, 796 and 803, respectively. And all cis-AB analysed and reported molecular genetically in Korea and Japan had T at np 467 (leucine at amino acid position 156). We report a first case of cis-AB with C at np 467 (proline at amino acid position 156). METHODS: Genomic DNA was extracted from peripheral blood of cis-AB patient and amplified by DS1/DS2 and DS3/DS4 allele-specific primers. After PCR, we analysed nps 261, 467, 526, 646, 703, 796, and 803 by restriction digestion, autoradiography and automatic sequencing. RESULTS: PCR-RFLP with DS1/DS2 primers and restriction enzyme KpnI showed that cis-AB had an 0 allele. The results of genomic sequencing, autoradiography and restriction digestion showed that cis-AB allele at nps 467, 526, 646, 703, 796 and 803 had C, C, T, G, C and C, respectively. CONCLUSION: This cis-AB showed characteristic molecular genetic features at nps 526, 703, 796, and 803. And this is a first case of A(Pro) cis-AB with C at np 467.

Reactive airways dysfunction syndrome (RADS) is a syndrome as a persistent bronchial hyperreactivity with asthmatic dyspnea which occurs after one or more inhalation exposures to a high concentration of irritant gasses, smokes or vapors in subjects who had preciously had no respiratory disease. We report a case of a 34 years old female worker suffering from reactive airways dysfunction syndrome who had been taking charge of guest room cleaning at a condominium. 7 months before, she inhaled high concentration of chlorine gas in confined and poor ventilated working space of bathroom at the condominium. As she was washing a bathroom with a bleaching agent (6 % sodium hypochlorite) without dilution, dyspnea, dizziness, headache, nausea, and coughing developed after work. She still suffer from dyspnea and coughing. All functional tests were normal except for methacholine challenge test which reveals bronchial hyperreactivity. She has some symptoms of dyspnea and coughing when exposed to perfume, cold air, and heavy work.

BACKGROUND: The Wada test is not yet standardized among epilepsy surgery centers, which makes it difficult to dis-cern the differences between its results. The objectives of this study were to examine the effects of memory stimulus types in the Wada test and the methods of score measurement of results. METHODS: We examined the Wada test in 59 patients with temporal lobe epilepsy who had language dominancy in left hemispheres. They underwent surgical treat-ment and were seizure-free for at least until the 1-year follow up. The Wada test was done on the patients using three different protocols during the presurgical evaluations: 1) protocol A; sixteen cards displaying eight line drawings of common objects and eight words, 13 patients, 2) protocol B; eight line drawings of abstract figures, 14 patients, and 3) protocol C; four line drawings of common objects and four line drawings of abstract figures, 32 patients. RESULTS: Thirty-three patients with RTL (right temporal lobectomy) and 26 patients with LTL (left temporal lobectomy) were not significantly different in demographic and disease characteristics such as age and sex, age at onset, risk factors before 2 years old, epilepsy duration, and Korean Wechsler Adult Intelligence Scale- IQ scores. Patients with RTL rec-ognized significantly more words and line drawings of common objects with a right injection than those with a left injection. Patients with LTL recognized significantly more line drawings of abstract figures and common objects fol-lowing a left injection versus a right injection. Correct rates obtained through discriminant function analysis (100% (A), 64% (B) and 84% (C) were higher than that obtained through cutoff criteria (memory asymmetry scores (3)25%: 82% (A), 62% (B) and 56% (C) ). CONCLUSIONS: Our study shows that line drawings of common objects as Wada memory stimuli are more useful for the lateralization of the epileptogenic hemisphere than line drawings of abstract figures and words. Discriminant function analysis is also a more effective score measurement than cutoff criteria.

PURPOSE: Cefodizime is a new third-generation cephalosporin which has a structure and immunomodutation properties similar to cefotaxime. Various studies on cefodizime have demonstrated the direct eradication of bacteria in cooperation with the host defense mechanism, particularly with phagocytosis. We evaluated the effects of cefodizime on the phagocytosis of COS-1 cells transfected with FcgammaRI/gammagamma or FcgammaRIIA cDNA. METHODS: Phagocytosis was measured using the in vitro COS-1 cell modeling system according to Schreiber's method. COS-1 cells, which lack endogenoous Fcgammareceptors but have phagocytic potential, were transfected with either FcgammaRI/gammagammaor FcgammaRIIA cDNA. COS-1 cells, as target cells, were treated with antibiotics for 1 or 24 hours and incubated for 30 min with IgG coated sheep RBCs. Adhered IgG coated sheep RBCs were removed after brief exposure to hypotonic phosphate buffered saline. Phagocytosis index (PI) was calculated as the number of ingested RBCs per 100 phagocytic cells after wright-Giemsa staining. RESULTS: COS-1 cells tranfected with FcgammaR (either FcgammaRI/gammagamma or FcgammaRIIA cDNA) showed the phagocytic activity against IgG coated sheep RBC, while untransfected COS-1 cells did not. After treatment with cefodizime, phagocytic activity of FcgammaRI/gammagammacDNA transfected COS-1 cells was significantly increased, while that of FcgammaRIIA cDNA transfected COS-1 cells did not. Marked enhancement of phagocytosis of COS-1 cells was observed after treatment with cefodizime, but was not observed with ceftriaxone or moxalactam. CONCLUSION: Cefodizime showed marked enhancement of phagocytic activity of FcgammaR transfected COS-1 cells. FcgammaRI seems to play an important role in the enhancement of phagocytosis. Further studies will be required.

PURPOSE: Insulin-like growth factor binding protein 3 (IGFBP-3) binds to IGF and acid labile subunit in blood, that regulates the action of IGF by modulating the interaction of IGF with the IGF receptor. Recent studies have shown that IGFBP-3 levels are decreased in prostate cancer patients. We examined IGFBP-3 profiles in prostate cancer patients and determined the effect of treatment on serum IGFBP-3 level in those patients. MATERIALS AND METHODS: Control groups were composed of age-matched healthy subjects and patients with benign prostatic hyperplasia (BPH). Patients with prostate cancer were divided into localized, locally advanced, metastatic and hormone-refractory. Serum samples were collected and stored at 70oC until use. The IGFBP-3 profile was measured by Western ligand blots. RESULTS: The serum IGFBP-3 level in patients with prostate cancer was significantly lower than healthy subjects or patients with BPH. Following the treatment of prostate cancer, IGFBP-3 was increased compared to that seen in pretreated prostate cancer. In hormone-refractory prostate cancer, IGFBP-3 was decreased again. However, there was no correlation between IGFBP-3 and tumor stage or Gleason score. CONCLUSIONS: These data show that IGFBP-3 levels are decreased in pretreated and hormone-refractory prostate cancer. Our results demonstrate that serum IGFBP-3 may be a useful marker in the detection and management of prostate cancer.
