In the treatment of congenital heart in Korea, a big progress has made so far, and successful results have been achieved. However, there were few reports pertaining to the age and cause of death in congenital heart disease patients. Now, the author made observation on the mortality, the age and the mode of death in 3817 patients of congenital heart disease who had been admitted to Severance Hospital during the period of 15 years, from Jan 1972 to Dec 1986. The overall hospital mortality of the congenital heart disease was 6.1% ; 10.1% in the unoperated cases and 4.5% in the patients who underwent surgery. The hospital mortality of indivisual congenital heart disease was, in the order of increasing frequency, 1.0% for ventricular septal defect, and for the complicated heart disease, such as transposition of great vessels(12.5%), and total anomalous pulmonary venous return(15.8%) the death rate was higher in general. The mortality was highest under 1 year of age, especially during the neonatal period, i.e. under 1 month of age. The mode of death in the unoperated cases were congestive heart failure, infection, and hypoxia, in the order of frequency, comprising 84.5%, and in the patients who underwent surgery were congestive heart faliure or low cardiac output syndrome and htpoxia, 62.3%. Among the patients who died in the neonatal period, 76.9% died without accurate diagnosis, and 38.5% were under 5 days of age. Hypoxia(27%), congestive heart faliure(19.4%), and sepsis(11.6%) were the main mode of death. The analysis of the dead patients with congenital heart disease revealed the following results.The mortality was high in the complicated heart disease ; the major mode of death in surgical patients were congestive heart faliure or low cardiac output syndrome ; and the mortality was high in patients under one year of age, especially in the neonates, and most of then lacked accurate diagnosis.Therefore, more accurate properative diagnosis of complicated heart disease and better surgical techniques, development of diagnostic tools in neonatal period, and the need for early surgery and emergency medical management are uregently demanded.

PURPOSE: This study was performed to identify the relationship between optimistic bias about health crisis and health behavior of Korean adults in a crisis of health, and to prepare baseline data for developing a health education and promotion program. METHODS: Study subjects were 595 adults aged from 19 to 64 who live in Korea. Data were collected through questionnaires administered by one interviewer. Descriptive statistics and Pearson's correlation coefficient were calculated using the SPSS program. RESULTS: The average score for optimistic bias about health crisis was 2.69, and that for health behavior was 107.05. The optimistic bias about health crisis showed a significantly positive correlation with health behavior (r=.187, p=.000). CONCLUSION: To make our results more useful, it is necessary to identity the causal relationship between health attitudes as an explanatory variable and optimistic bias as an outcome variable. In addition, a relatively low score in optimistic bias from this research compared to other studies must be explained through further studies considering unique Korean cultural background. Moreover, research of the relationship between optimistic bias about health crisis and health behavior looking at people who don't have good health behaviors is needed.

Panax ginseng roots have long been used as a medicinal herb in oriental countries. We have investigated anti-proliferative effects of lipid soluble Panax ginseng components on human renal cancer cell lines. Petroleum ether extract of Panax ginseng roots (GX-PE) or its partially purified preparation (7:3 GX) was added to cultures of three human renal cell carcinoma (RCC) cell lines, A498, Caki-1, and CURC II. Proliferation of RCC cells was estimated by a [3H]thymidine incorporation assay and cell cycle distribution was analyzed by flow cytometry. GX-PE, 7:3 GX, panaxydol and panaxynol inhibited proliferation of all three RCC cell lines in a dose dependent manner in vitro with an order of potency, 7:3 GX > panaxydol > panaxynol = GX-PE. Additive effect of interleukin 4 was also demonstrated, most prominently in Caki-1 which responded poorly to GX-PE alone. Analysis of cell cycle in CURC II and Caki-1 treated with GX-PE demonstrated increase in G1 phase population and corresponding decrease in S phase population. The present study demonstrated that proliferation of human RCC cell lines were inhibited by lipid soluble components of Panax ginseng roots by blocking cell cycle progression at G1 to S phase transition.

Background: Oxidative stress is generally accepted as one of the principal pathogenesis of vitiligo, and keratinocyte-melanocyte interactions are also thought to play critical roles. It is well-known that antioxidant response and autophagy protect cells against oxidative damage, but the details and the compensatory relationship between the two mechanisms in the keratinocytes of vitiligo lesions remain unclear. Objective: To evaluate the antioxidant response and autophagy status of patients with vitiligo and to explore the interactions between these two mechanisms. Methods: Ten patients with clinicopathologically proven vitiligo and 10 normal controls were enrolled in our Department of Dermatology, Soonchunhyang University Hospital, Bucheon, Korea. Tissue samples of vitiligo lesions in the patient group and normal skin in the control group were immunohistochemically stained for nuclear factor erythroid 2-related factor 2 (Nrf2), Beclin-1, microtubule-associated protein light chain 3 (LC3)-II, and p62. The immunopositivity of epidermal keratinocytes was evaluated. Results: Keratinocytes in vitiligo lesions had a significantly lower expression of Nrf2 (p=0.002) than that in the cells of normal controls. The levels of autophagy markers did not differ significantly between the two groups, but decreases in the Beclin-1 and LC3-II levels, and an increase in the p62 level in the patient group may indicate a small decrease in autophagy of patients with vitiligo. Conclusion Decreased antioxidant response and reduced autophagy may trigger melanocyte apoptosis in vitiligo lesions.
