  • Locally advanced cervical carcinoma has shown high rate of local failure and poor survival rate despite the advances in modern radiation therapy techniques. Combination of chemotherapy and radiation therapy demonstrated benefit in improving local control and possibly the overall survival. Twelve patients with advanced stages (Figo stage III, IV) or 11b with bulky tumors (>5 cm in diameter) were treated with combination of radiation therapy and concurrent weekly cisplatin between May of 1988 and September of 1991 at Inje University Paik Hospital. Cisplatin was administered in bolus injections of 50 mg at weekly intervals during the courses of radiation therapy. Median follow-up period was 34 months with ranges from 3 to 53 months. Eleven patients were evaluable for the estimation of response. Response was noted in all the 11 patients: complete response (CR) in 7 ($64\%$), partial response (PR) in 4 ($36\%$). Of the 7 patients with CR, all maintained local control, whereas only 1 of 4 with PR showed local control. Six of 7 with CR are alive disease free on the completion of follow-up. Eight of 11 patients ($73\%$) maintained local control in the pelvis. The median survival for CR patient is 27 months and 9 months for the PR patients. Analysis of survival by stage shows 11 b 4/5, III 2/3 and IV 1/3. Overall survival rate was $61\%$. Three patients recurred: 1 at local, 1 in distant site and 1 with local and distant site. Toxicity for the combination therapy was not excessive. These results are preliminary, but definitely encouraging in view of markedly improved response rate compared with the results of historical control group.

  • Occupational dermatosis is one of the most prevalent occupational disorders. However, the extent of the occupational dermatoses including incidences and prevalencies of each disease entity, and etiologic materials are not yet welt stated in Korea. Authors reviewed the literatures on the statistic data and reports on the occupational dermatoses, and surveyed on the occupational dermatoses in two factories, and surveyed the physicians responsible to the occupational dermatoses with formed questionnaire. The results are as follows; 1. Among medical journals published since 1964, there were 31 articles on the occupational dermatoses. Of 31 articles, 18 were case reports and all others were review articles. Of 18 case reports, 9 were epidemiologic survey. The Workers' Periodic Health Examinations revealed that prevalence of the occupational dermatoses was highest(4.36 per 10,000 workers) in 1974, but number of the cases reported were decreased sharply since 1978 with some tendency to increase since 1981. There were 2,240 reported cases of occupational dermatoses between 1966 and 1992, which is 1.90% of all the reported occupational diseases. Skin infection and injuries due to chemicals were most frequent and there were 6 cases of skin cancer. 2. In an epidemiological survey on the dermatoses among 995 workers in a metal product manufacturing factory and 225 workers in a coal chemical factory, there were 794 with dermatomycosis, 296 workers with acne, 130 workers with scar, 123 workers with deformity of toe nails. Scars, photosensitivity dermatitis, deformity of finger and toe nails, and acne were more prevalent in the metal product manufacturing factory(p<0.05). In the metal prouct manufacturing factory, workers treating organic solvents and oils had more dermatoses than those without treating the materials(p<0.05). On the skin patch performed on 16 workers in the metal product manufacturing factory, there were 8 cases of irritation dermatitis and 5 cases of contact dermatitis. Prevalence of contact dermatitis in the metal product manufacturing factory was 1.3%. 3. On the questionnaire survey, 34 dermatologists, 29 doctors of preventive medicine, and 22 family physician replied. The proportion of occupational etiology among all dermatoses assumed by the physicians were below 9%, and the most important occupational dermatosis in Korea was contact dermatitis. Main etiologic materials related to the occupational dermatosis were organic solvent, acid and alkali, and metals. The reason for the scarcity of report of occupational dermatoses were difficulty in diagnosis and physician's ignorance of the occupational etiology. They replied that to prevent the occupational dermatoses in the workplace, the use of protective devices was most important, and development of diagnostic criteria on the occupational dermatoses is urgent. Above results shows us that there is many workers with occupational dermatoses, but they are mostly unreported. Measures to prevent and manage the occupational dermatoses are not satisfactory at present. Hence, authors suggest measures for the precise diagnosis, report and prevention of the occupational dermatoses. a. Dermatologist, preventive physician, and industrial hygienist should work as a team to examine the high risk group and establish the preventive measures. b. Disease entities, diagnostic criteria of occupational dermatoses should be listed, criteria for the compensation and job fitting at recruitment should be established, and manual for the proper treatment and effective prevention of each occupational dermatosis should be developed. c. Patch test antigens against each occupational category should be developed and it should be available to any physicians responsible. d. To facilitate the diagnosis of occupational dermatoses by the doctors responsible for the Workersr Periodic Health Examination, development of standardized questionnaire, education on the techniques of the patch test, and cooperation with the dermatologist in diagnosis of occupational dermatoses is essential.

  • Peroxisome proliferator activated receptor (PPAR)-$\alpha$ of three PPAR subtypes ($-\alpha,\;-\beta/-\gamma,\;-\delta$), which are members of the nuclear hormone receptor superfamily of ligand-activated transcription factors, plays a key role in lipoprotein and glucose homeostasis. A variation in the PPAR-a gene expression has been suggested to influence the development of metabolic syndrome through alterations in lipid concentrations. The aim of our study was to investigate the association between the PPAR-a and metabolic syndrome among South Korean. A total of 542 health screen examinees were enrolled in this study who were examined in Kosin University Gospel Hospital from December, 2004 to July, 2005. The height, weight, waist circumference, and systolic and diastolic blood pressure of the subjects were examined and fasting blood glucose, total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride were measured by-sampling in venous blood. The metabolic syndrome was defined as the presence of three or more of the following : waist circumference men ${\geq}90cm$, women ${\geq}80cm$, blood pressure ${\geq}130/85mmHg$, fasting glucose ${\geq}110mg/dL$, HDL cholesterol men <40 mg/dL, women <50 mg/dL, triglyceride ${\geq}150mg/dL$. The blood pressure, fasting glucose, HDL cholesterol, triglyceride were evaluated by using the criteria of NECP ATP III and waist circumference was assessed by using the criteria of WHO Asia-Western Pacific. And the author compared the frequency of the PPAR-$\alpha$ mutation of L162V ($C{\rightarrow}G$ variant in exon 5) in a sample of 542 subjects with and without the metabolic syndrome by polymerase chain reaction allele-specific oligonucleotide (PCR-ASO) method. One (0.2%) hetero-isotype among high risk of metabolic syndrome was identified. The values of waist circumference, body mass index and low density lipoprotein cholesterol of the mutant were 100 cm, 28.6 $kg/m^2$ and 120 mg/dL, respectively. Although the author failed to see significant association between the presence of the PPAR-$\alpha$ L162V polymorphism and metabolic syndrome, one PPAR-$\alpha$ L162V polymorphism in metabolic syndrome patients was found.

  • Purpose : The hematologic change during the treatment of acute lymphoblastic leukemia(ALL) is critical as a prognostic determinant and a variable to determine the dose of chemotherapeutic agents. It is known that the dose of vincristine used in the maintenance phase of ALL is small enough to increase the count of platelet. To investigate the change of platelet count according to the vincristine administration in maintenance phase of ALL chemotherapy, we performed this study. Methods : Eleven patients eligible under the criteria of Children's Cancer Study Group(CCG)-1882 and who had completed chemotherapy were enrolled in this study. The count of platelets before vincristine administration was compared with those of vincristine administration 1, 2 and 3 weeks after the early and last periods of maintenance phases. The platelet count before vincristine administration was defined as 100 percent and that after vincristine were compared. In addition, we tentatively defined an enhancing effect of vincristine as positive when the relative count was more than 120 percent. Results : Platelet count did not differ according to the early and last periods of maintenance phase. Platelet count at first week after vincristine administration increased more significantly than that before vincristine in early and last periods. There was an enhancing effect in 10(90.9 percent) of 11 patients after 1 week vincristine administration both in the early and last periods of the maintenance phase. Conclusion : Vincristine, used in ALL maintenance phases as a low dose, increased platelet count 1 week after administration. The increased platelet count resumed to the previous level 2-3 weeks later. However, the thrombocytosis observed in the maintenance phase by vincristine was not high enough to induce thrombosis. In addition, vincristine is known to reduce the activity of platelets. Therefore, the risk of thrombosis in the maintenance phase of ALL chemotherapy would be low.

  • Purpose: This study aimed to investigate the association of total dietary antioxidant capacity (TAC) with oxidative stress and metabolic markers among patients with metabolic syndrome according to gender. Methods: A total of 346 subjects aged 30~59 years with two or more risk factors of metabolic syndrome were recruited from a general hospital near Seoul in South Korea between 2010 and 2012 based on data from the medical checkup. Biochemical indices for oxidative stress and metabolic markers were measured. Food consumption data from 3-day food records were linked with the antioxidant capacity database for commonly consumed Korean foods to estimate individual's TAC. Results: Average dietary TAC of the study subjects was 132.0 mg VCE/d/1,000 kcal in men and 196.4 mg VCE/d/1,000 kcal in women. Levels of ${\gamma}$-glutamyltransferase (GGT), systolic blood pressure, diastolic blood pressure, and blood triglycerides were reduced significantly according to increasing TAC in men, but there was no significant trend in women. Intakes of total flavonoids and carotenoids were significantly negatively correlated with GGT (p < 0.05) and d-ROMs (p < 0.01) in men, whereas those of ${\alpha}$-tocopherol (p < 0.05) and ${\gamma}$-tocopherol (p < 0.05) were positively correlated with biological antioxidant potential (BAP) in women. The odds ratio of high oxidative stress indices and abnormal metabolic markers according to TAC level were not significant in either men or women. Conclusion: The results show that dietary TAC was partially associated with oxidative stress and metabolic markers among patients with metabolic syndrome. Further research is required for elucidating the association between dietary TAC and incidence of metabolic syndrome and chronic diseases within a large population in prospective studies.

  • Background: Mortality and morbidity of anastomotic complications after esophagectomy have gradually decreased in recent years. However, swallowing difficulties and reflux symptoms after esophagogastrostomy continue to be a burden jeopardizing the quality of life. In the present study, we evaluated the quality of esophagogastrostomy by analyzing anastomotic stenosis and reflux esophagitis. Material and Method: A retrospective analysis was made in 74 patients who underwent esophagogastrostomy after esophagectomy by one surgeon between January 1995 and December 2004. 53 patients of them received endoscopic examination during follow-up($29{\pm}23.6$ months, range $5{\sim}111$ months). Reflux esophagitis and stenosis at anastomostic site were analyzed according to the techniques and locations of esophagogastrostomy. Result: The median age at the time of repair was $60.3{\pm}8.87$ years(range $39{\sim}81$ years). 23 patients received a hand-sewn esophagogastric anastomosis and 30 patients a circular stapled one. There was no significant statistical difference in terms of anastomotic stenosis(p=0.64) and reflux esophagitis(p=0.41) between the two groups. Cervical anastomosis was peformed in 26 patients and intrathoracic anastomosis in 27 patients. No significant statistical difference in anastomotic stenosis between the two groups was found(p=0.44), but reflux esophagitis was noted in 3 patients in the cervical anastomosis group and 14 patients in the intrathoracic anastomosis group(p=0.003). Conclusion: Cervical anastomosis was supposed to have a better quality of esophagogastrostomy by lowering the risk of reflux esophagitis. In the future, the comprehensive study including a patient's subjective symptom and Barrett's metaplasia should be performed in larger cases.

  • The purpose of this study was to investigate the concentration levels, distribution characteristics and blood concentration of Polycyclic Aromatic Hydrocarbons (PAHs) at ambient air in Industrial Complex Area. The samples were collected at 4 sites in Industrial Complex Area and its vicinities. The result indicated that there was the difference of PAHs concentration as followed local characteristics. The level of average concentration of PAHs in the air in Industrial Complex Area was $14.52{\sim}193.48ng/m^3$. The level of average concentration of six materials with possibility of cancer creation was $1.65{\sim}13.44ng/m^3$. The concentrations of PAHs were generally low, but Jechul-dong is considered an area where consistent monitoring of PAHs is required. In addition, benzo(a)pyrene was detected in every atmospheric sample, however the concentration was not high. The level of concentration of benzo(a)pyrene in the air in the Jechul-dong was $2.89ng/m^3$. But, the concentration of the PAHs in Jechul-dong showed that the Benzo(a)pyrene concentration is above $1ng/m^3$ of air quality standard(EU). The results of the concentration level of PAHs in the blood from 240 persons who were exposed directly were surveyed, it was $1.12{\sim}11.45ng/m^3$ for man and $1.20{\sim}26.89ng/m^3$ for woman. It was indicated that the difference between the genders was very little. The accumulation inside human was anticipated as the PAHs concentration in the blood for the aged was very high. Industrial Complex Area and its vicinities are an area which has been greatly influenced by PAHs and environmental contaminants. It is necessary to control the emission sources of PAHs and to construct an observation system at Industrial Complex Area from now on. It is time to reduce the risk factors for health and environmental disease to protect the health of resident in Industrial Complex Area and its vicinities.

  • There is an increasing interest in the potential of isoflavone in reducing the risk of cardiovascular disease and cancer, however, although several effects of isoflavone as a component of soy protein are well established, the hypolipidemic and antioxidant effects of purified isoflavone are still controversial. This study was to investigate the effects of isoflavone on serum lipid profiles and antioxidant status in rats. 7-week old male Sprague Dawley rats were fed one of the following diets for 8 weeks: basal diet (B), basal+0.3% isoflavone (BI), basal+0.5% cholesterol (BC), or basal+0.3% isoflavone +0.5% cholesterol (BIC). Two-way ANOVA was used to test the effects of dietary isoflavone and cholesterol supplementation and their interaction on variables. Serum lipid profiles and total antioxidant status (TAS) were examined spectrophotometrically. Degree of serum lipid peroxidation was measured by malondialdehyde (MDA) assay. The activities of serum antioxidant enzymes (GSH-Px, total-SOD) was determined. Levels of serum total cholesterol, VLDL+LDL-cholesterol and Atherogenic index were significantly lower in BI than those levels in group B (p=0.0002, p<0.0001, and p=0.0042, respectively). Serum total antioxidant status (TAS) levels were significantly higher, in both isoflavone supplemented groups (BI, BIC) compared to those levels in each control group (B, BC) (p<0.0001). Activity of total-SOD was significantly higher in BI compared to the activities in group B (p=0.0317). There was no interaction between isoflavone and cholesterol supplementation. In conclusion, isoflavone supplementation showed positive effects on the serum lipid profiles and total antioxidant activities in both conditions, either when fed a diet with or without cholesterol. These effects of isoflavone were independent of cholesterol supplementation.

  • Purpose: In 2003, we decided to buy a PET/CT, at the time, it was the latest cancer diagnostic medical equipment. Equipment company was offered the marketing of collaboration operation because the highly cost of PET/CT. However, this hospital's choice was own purchase way. In this study we evaluated the collaboration operation way by post-mortem analysis to the current situation. Materials and Methods: From 2004 until 2008, five years, we investigate the revenue analysis the number of PET/CT cases about own purchase way and collaboration operation way according (ABC costing). Results: The year 2004, own purchase way is 4 billion 9 thousand 2 hundred million won in deficit, the collaboration operation way is 1 billion 1 thousand 7 hundred million won in deficit. The year 2005, own purchase way is 1 billion 5 hundred million won in deficit, collaboration operation way is 8 thousand 7 hundred million won in deficit. However, the year 2006, own purchase way is 5 billion 1thousand 3 hundred million won in surplus, collaboration operation way is 9 thousand 9 hundred million won in deficits. The year 2007 and 2008, revenue of own purchase way is more increased but the collaboration operation way is more decreased. From the year 2004 to 2008, subtotal of own purchase way is 10 billion 8 thousand 8 hundred won in surplus, sub-total of collaboration operation way is 6 billion 7 thousand million won in deficit. Conclusion: Own purchase way has been a big benefit occurs and to reflect the equipment price, the collaboration operation way became to deficit continues. In other words, the problem of collaboration operation way showed us. When you buy the high cost Equipment, consideration will be risk and economic analysis of variance, the appropriate of the initial investment cost, clinical diagnostic needs and etc.

  • The common word flavonoids is often used to classify a family of natural compounds, highly abundant in all higher plants, that have received significant therapeutic interest in recent years. Naringin is associated with a reduced risk of heart disease, neurodegenerative disease, cancer and other chronic diseases; however the molecular basis of this effect remains to be elucidated. Thus we attempted to elucidate the anti-allergic effect of Naringin in ovalbumin (OVA)-induced asthma model mice. The OVA-induced mice showed allergic reactions in the airways. These included an increase in the number of eosinophils in bronchoalveolar lavage (BAL) fluid, an increase in inflammatory cell infiltration into the lung around blood vessels and airways, airway luminal narrowing, and the development of airway hyper-responsiveness (AHR). The administration of Naringin before the last airway OVA challenge resulted in a significant inhibition of all asthmatic reactions. Accordingly, this study may provide evidence that Naringin plays a critical role in the amelioration of the pathogenetic process of asthma in mice. These findings provide new insight into the immunopharmacological role of Naringin in terms of its effects on asthma in mice.
