In the plywood manufacturing factory established in 1979, female 3 workers who had exposed to adhesives containing formaldehyde for more than 48 months of duration suffered from eye, nasal, oral, throat and skin irritation and dyspnea as chief complaints. The actual level of the exposure to formaldehyde were not estimated when the exposed workers started to have above symptoms. The environmental monitoring of workplace was measured on April 25, 1990, and the concentration of formaldehyde revealed 0.2 ppm, however the exhaustive ventilatory system was already installed at that time. Twenty six subjects from entire factory were examined by questionnaire, physical examination and spirometry, etc. on August 22, 1990. Significant difference was observed in symptoms and signs of nasal, oral and throat irritation between the exposed group with longer duration and that with short duration. When the exposed group with longer duration was compared to the group of nonexposed, symptoms and signs of nasal, oral, throat and skin irritaion, chest tightness and dullness were significantly increased in the former group. The results of the spirometric test showed that the forced vital capacity and the forced expiratory volume at 1 second were decreased among the exposed group with longer duration but not significant.
Purpose : The aim of this study was to evaluate whether the incidence of relapse or nephritis might be influenced by the duration of corticosteroid therapy in children with Henoch-Schonlein purpura(HSP). Methods : We retrospectively analyzed 186 children with a diagnosis of HSP in two major hospitals in Ilsan, Korea from the years 2000 to 2003. To evaluate whether renal involvement or relapse might be influenced by the duration of corticosteroid therapy in children with HSP, one pediatric nephrologist from hospital A, maintained corticosteroid therapy for at least 2 weeks(Group A, n=94). The other from hospital B used only during the symptomatic period(Group B, n=92). Results : There were no significant differences in age, sex, body weight, white blood cell count, hemoglobin, hematocrit, platelet count, serum protein and albumin levels between the two groups. The incidence of abdominal pain or arthralgia also did not differ between two groups. However, the duration of steroid therapy was significantly longer in Group A than in Group B and the cumulative dose of prednisolone was also higher in Group A than in Group B. The development of nephritis was more frequent in Group A. Conclusion : The longer duration of steroid use was not associated with the decreased rate of nephritis. Therefore, corticosteroids should be used carefully in a selected group of HSP children, and be tapered rapidly after control of the acute symptoms.
Eighty five patients of oral cavity cancer, treated with radiation at the Department of Therapeutic Radiology, Korea Cancer Center Hospital, during the period from March 1985 to September 1990 were analyzed retrospectively. Among 85 patients, 37 patients were treated with radiation only and 48 patients were treated with radiation following surgery. And 70 patients received external irradiation only by $^{60}Co$ with or without electron, the others were 7 patients for external irradiation plus interstitial implantation and 8 patients for external irradiation plus oral cone electron therapy. Primary sites were mobile tongue for 40 patients, mouth floor for 17 patients, palate for 12 patients, gingiva including retromolar trigone for 10 patients, buccal mucosa for 5 patients, and lip for 1 patient. According to pathologic classification, squamous cell carcinoma was the most common (77 patients). According to AJC TNM stage, stage I + II were 28 patients and stage III+IV were 57 patients. Acturial overall survival rate at 3 years was $43.9\%,$ 3 year survival rates were $60.9\%$ for stage I + II, and $23.1\%$ for stage III+IV, respectively. As a prognostic factor, primary T stage was a significant factor (p<0.01). The others, age, location, lymph node metastasis, surgery, radiation dose, and cell differentiation were not statistically significant. Among those factors, radiation plus surgery was more effective than radiation only in T3+T4 or in any N stage although it was not statistically sufficient (p<0.1). From those results, it was conclusive that definitive radiotherapy was more effective than surgery especially In the view of pertainig of anatomical integrity and function in early stage, and radiation plus surgery was considered to be better therapeutic tool in advanced stage.

Metabolic disease is associated with abdominal obesity, high blood pressure, and dyslipidemia. Physical activity has beneficial effects on a variety of diseases. This study examined the relationship between metabolic diseases and physical activity according to age. Among a total of 7,295 subjects, the data from 382 individuals in the normal group and 1,525 persons in the metabolic disease group were analyzed. The data were analyzed statistically by one-way ANOVA, the Pearson's correlation coefficient, and multiple regression analysis. The levels of hemoglobin (HB), hematocrit (HCT), and creatinine (CR), were elevated when a high-intensity physical activity was performed, but they were reduced when a low-intensity physical activity was performed in the normal group aged 10~29 years and the metabolic disease group aged 50~69 years. In the normal group and metabolic disease group aged 30~49 years, the level of high density lipoprotein cholesterol (HDL-C) was elevated when high-intensity physical activity was conducted, whereas it was reduced when low-intensity physical activity was performed. No difference in the level of HDL-C depending on age and exercise intensity was observed in the normal group; the level of HDL-C decreased with age and increased with exercise intensity in the metabolic disease group. Physical activity has different effects in metabolic disease depending on age.

Korean traditional deer decoction (Nogjungtang), composed of oriental herbs and almost deer parts, has been used as an important resource for human health. For basic studying on Nogjungtang, this experiment was conducted to evaluate nutritional effects of Nogjungtang, and estimate its effect on growth, food efficiency, organ development and hematological indices in growing and adult Sprague-Dawley rats. The rats were divided into three groups as follows; control: non-supplementation, Notiungtang I: recommended dose, and Nogjungtang II: thrice recommended dose. Nogjungtang was composed of various general nutrients with up 93$\%$ moisture.Crude protein is the highest value as 22.78$ \%$, Mg is a major mineral as 0.48$\%$ compared to other minerals, and methionine and proline are higher by 1.31 and 1.67$\%$ than other amino acids based on dry matter, re-spectively. In both growing and adult rats, there were no significant difference in body weight gain and feed intake between the control and Nogjungtang groups. Also, organs weights (liver, heart, kidney and stomach) and hematological indices (WBC, RBC, Hb, Hct and Platelet) did not show statistically significant differences among the experimental groups. However, all of experimental rats were normal growth without hypertrophy or negative development of organs by Nogjungtang. Hematological indices maintained in normal value by thrice recommended dose of Nogjungtang. The average body weight of each treatment groups showed similar levels at end of experiment. In case of the feed efficiency ratio (feed intake/body gain), the growing rats showed 6.00, 5.81 and 5.99 and adult rats showed 9.03, 8.98 and 9.10 in control, Nogjungtang I and Nogjungtang II, respectively. In conclusion, although further investigation of Nogjungtang should be performed in the functions registered in many ancient literatures, Nogjungtang is physiologically safe and may have potential as candidate food for human health.

The effects of Paecilomyes japonica on weight gains, food intakes, food efficiency ratios, serum and hepatic lipid concentrations, serum protein levels and serum enzyme activities, were studied in adult male rats. Sprague-Dawley rats,35 weeks old, were given four different types of diets for a succeeding period of five weeks: either a normal diet (5% corn oil), a control diet (high fat; 5% corn oil + 15% lard), a PF diet (control diet + 3% fruiting body of Paecilomyes japonica), or a PM diet (control diet+.3% mycelium of Paecilomyes japonica). The body weight gains, hepatic weights and food efficiency ratios of rats fed the PF or PM diets were significantly lower than those fed the control diet, but were similar to those fed the normal diet. The concentrations of hepatic total lipids, cholesterol and triglyceric, and serum triglyceride, of rats given the PF or PM diets were significantly lower than those given the control diet. Hut the concentrations of total cholesterol, HDL-cholesterol, LDL-cholesterol and phospholipid in the serum of rats fed the control, PF or PM diets were significantly higher than those fed the normal diet. In the serum of rats fed the PF diet, the HDL-cholesterol/total cholesterol ratio was significantly higher and the atherogenic index was significantly lower than those fed the control diet, while such effect was not observed in rats fed the PM diet. The alkaline phosphatase activity in the serum of rats fed the control and PM diets was more significantly decreased compared to rats fed the PF and normal diet. No differences were noted in the weights of the pancreas, kidney and heart, the serum concentrations of glucose, hemoglobin and albumin, and the activities of GOT, GPT and ${\gamma}$-GTP, among the rats on all the experimental diets. In conclusion, the rats fed the PF or PM diets maintained normal body and hepatic weights. Despite of the high intake of fats in the PF and PM diets, the concentrations of hepatic total lipids, cholesterol and triglyceride, and serum triglyceride were decreased.

This nutrition survey was carried out twice(Spring and autumn) in Sam Chung-Ri, Song Kwang Myun, Soong Ju-Gun. The food intakes of 92 family members were measured by weighing method. Also 45 adults were examined for anthropometric, blood content and blood pressure. The results abtained were summarized as follows; In vegetable foods, the intake of rice was high, but that of legumina and other cereals was low. In animal foods, the intake of milk and eggs was low, and that of oils and fats was very low. However, the food intake between spring and autumn showed remarkable difference. The average intake of calorie, protein, Ca, Fe and vitamin $B_2$ except vitamin $B_1$ and niacin was below the RDAs. The percentage of carbohydrate, protein and fat for energy was 82.2, 11.6 and 6.2%, respectively. The results of anthropometry of height, weight and chestcircumference showed that both sexes Were below Korean Standards. The concentration of Hb & Hct was normal in both sexes, and the rate of anemia was low. The concentrations of plasma glucose, protein, lipids, and blood pressure were normal in both sexes. In case of male, the correlation between plasma albumin and nutrients intake was significant, but the case of female showed different tendency. In case of male, the correlation between weight, height and plasma protein was also significant but the case of female showed different tendency. The rate of parasite infection was very low $(2.17%{\ldots}3.26%)$

Purpose: Laparoscopic surgery for gastric cancer was introduced in the past decade because it was considered less invasive than open surgery, and this results in less postoperative pain, faster recovery and an improved quality of life. Several studies have demonstrated the safety and feasibility of this procedure. We examined the outcome of performing laparoscopic surgery for gastric cancer over the last two year. Materials and Methods: From April 2004 to December 2006, 329 patients with gastric adenocarcinoma underwent a laparoscopy-assisted distal gastrectomy with lymph node dissection. The data was retrospectively reviewed in terms of the clinicopathologic findings, the perioperative outcomes and the complications. Results: The total patient group was comprised 196 men (59.6%) and 133 women (40.4%). The mean BMI was 23.6 and the mean tumor size was 2.7 cm. The mean number of harvested lymph node was 22.7, and this was 18.6 before 30 cases and 23.1 after 30 cases, and the difference was significant (P=0.02). The mean operation time was 180.9 min, and this was than 287.9 min before 30 cases and 170.2 min after 30 cases. After 30 cases, there was a significant improvement of the operation time (P<0.01). The mean incision length after 30 cases was shorter than that before 30 cases (P<0.01). Postoperative complications occurred in 24 (7.3%) of 329 patients and there was no conversion to open surgery. Conclusion: Even though the LADG was accompanied by a difficult learning curve, we successfully performed 329 LADG procedures over the past 2 years and we believe that LADG is a safe, feasible operation for treating most early gastric cancers (EGC).
Purpose: Many patients suffer with anemia after gastrectomy. Iron deficiency due to a decreased oral intake and malabsoption is the most common cause of anemia in gastrectomized patients. This study evaluated the efficacy of administering intravenous iron sucrose for treating patients with anemia. Materials and Methods: From May 2007 to October 2007 at Yonsei University Severance Hospital, we reviewed 47 outpatients whose hemoglobin levels were below 11 g/dl after gastrectomy. Iron sucrose was used for iron supplementation. To determine the difference between before and after the treatment (at 1 week, 2 weeks, 3 weeks, 3 months and 6 months after treatment), we prospectively examined such anemia parameters as the hemoglobin level (Hgb), the hematocrit (Hct), serum iron, TIBC, ferritin and transferin. Results: Out of the 47 patients, only 36 completed their treatment. Eleven were male and 25 were female. The Hgb levels, which indicate anemia, were elevated 0.6, 0.8, 1.3, 2.1 and 2.2 g/dl after 1 week, 2 weeks, 3 weeks, 3 months and 6 months after administration, respectively (P<0.001). The changes from 1 week to 3 months were statistically significant, but those from 3 to 6 months were not. The Hgb levels of 26 patients, which accounted for 72% of all the patients, elevated up to 12 g/dl or more. No side effects or complications were found, but there was one case of temporary nausea. Conclusion: Anemia after gastrectomy is safely treated in a relatively short time with administering iron sucrose. The patients' Hgb levels are expected to increase in a week and keep increasing up to 3 months.
Purpose : The aim of this study is to analyze the treatment failure patterns and the risk factors for locoregional or distant failure of uterine cervical carcinoma treated with radiation therapy. Materials and methods . A retrospective analysis was undertaken of 154 patients treated with curative radiation therapy in Gyeongsang National University Hospital from April 1989 through December 1997. According to FIGO classification, 12 patients were stage IB, 24 were IIA, 98 were IIB, 1 were IIIA, 17 were IIIB, 2 were IVA. Results : Overall treatment failure rate was $42.1\%$ (65/154), and that of complete responder was $31.5\%$ (41/130). Among 65 failures, 25 failed locoregionally, another 25 failed distantly, and 15 failed locoregionally and distantly. Multivariate analysis confirmed tumor size (>4 cm) as risk factor for locoregional failure, and tumor size (>4 cm), pelvic lymph node involvement as risk factors for distant failure. Conclusion : On the basis of results of our study and recent published data of prospective randomized study for locally advanced uterine cervical carcinoma, we concluded that uterine cervical carcinoma with size more than 4 cm or pelvic lymph node involvement should be treated with concurrent chemoradiation.
