1.Effect of dietary supplementation of grape skin and seeds on liver fibrosis induced by dimethylnitrosamine in rats.
Nutrition Research and Practice 2010;4(5):369-374
Grape is one of the most popular and widely cultivated fruits in the world. Although grape skin and seeds are waste product of the winery and grape juice industry, these wastes contain large amounts of phytochemicals such as flavonoids, phenolic acids, and anthocyanidins, which play an important role as chemopreventive and anticancer agents. We evaluated efficacies of grape skin and seeds on hepatic injury induced by dimethylnitrosamine (DMN) in rats. Treatment with DMN significantly increased levels of serum alanine transaminase, aspartate transaminase, alkaline phosphatase, and bilirubin. Diet supplementation with grape skin or seeds (10% daily for 4 weeks) prevented these elevations. The grape skin and seeds also restored serum albumin and total protein levels, and reduced the hepatic level of hydroxyproline and malondialdehyde. Furthermore, grape skin and seeds reduced DMN-induced collagen accumulation, as estimated by histological analysis of liver tissue stained with Sirius red. Grape skin and seeds also reduced hepatic stellate cell activation, as assessed by alpha-smooth muscle actin staining. In conclusion, grape skin and seeds exhibited in vivo hepatoprotective and antifibrogenic effects against DMN-induced liver injury, suggesting that grape skin and seeds may be useful in preventing the development of hepatic fibrosis.

The purpose of this study is to estimate cesarean section rate in Korea and analyze the socioeconomic variables and health resources which affect regional variation in the rate. Samples were drawn from the record of vaginal and cesarean section deliveries based upon insurance claim bills which have been submitted to the National Federation of Medical Insurance for the first three months, January through March, 1991. The results are obtained as follows: It was found that, cesarean section rate was increasing rapidly up to 23.1% in 1991. Cesarean section per 10 thousand insured people was 4.8 and the number of cesarean section per 10 thousand insured eligible(15-49 years old) female was 7.6. The fee for normal delivery was 109,489 won and that for cesarean section was 390,024 won. The average days of hospitalization in normal delivery was 2.3 days, and those in cesarean section was 7.6 days. On the average cesarean section has a longer of stay as much as by 4.3 days and cost 3.6 times more than normal deliveries. Cesarean section rates vary among medical facilities: 19.8% at clinics 37.6% in small-scale hospitals, and 29.1% in general hospitals. The regional variation of cesarean section rates was also fairly prominent. The South Cheju Gun has the highest rate of cesarean section, 56.2%. Meanwhile no cesarean section cases has been reported in Sunchang Gun during the period of this study. The variation is noted among provinces. The rate for Cheju province has been 3.4 times higher than that for Chunnam. The number of cesarean section per 10 thousand insured people vary greatly among regions, too. This study has found that there exists significant regional variations among various geographic units in terms of average length of stay, average cost, number of obsretricians and number of beds. Multiple regression analysis was done to identify factors explaining the regional variance of various cesarean section rates: In the urban areas, no significant explaining variables were noted except the number of beds for the dependent variable of cesarean section cases per 10 thousand insured eligible females. The smaller the number of bed, the more cases of cesarean section was noted for an urban area. The is mostly because the rate of cesarean section is higher in medium-size hospitals than in large general hospitals. In the rural areas, the factor of education has been found significant for all three dependent variables. The higher the educational level, the rate of cesarean section is most likely to rise. An income variable measured by the amount of monthly insurance contribution has been identified a powerful predictor in explaining the variance of cesarean section rates. The same has been noted for the number of obstetricians. Similar findings are observed for the country as a whole. The income level has been found as the most powerful explaining factor in the regional variance of cesarean section rates. In general the rate is higher in the urban areas, and lower in the area with more small hospitals. As this is the initial attempt to identify the factors relevant to the regional difference in the rates of cesarean section, more elaborated study is urgently required.

Highly specific and sensitive immunoassay method for soluble human recombinant interleukin-6 (hu rlL-6) was established by two different immunization methods. One is conventional method by Freund's adjuvant method and the other is special method which is directly injected to mouse spleen. Among seven established monoclonal antibodies (mAbs), two typical monoclonal antibodies, designated YB3 (IgG1) and NY2 (IgM), were further characterized. These mAbs highly bound to IL-6, however did not show cross reactivity with IL-1B and IL-2. As the results of ELISA inhibition assay and western blotting method, it was further identified that YB3 and NY2 had high binding specificity with IL-6. And the limiting detection amount of rlL-6 for YB3 was 5 ng/ml and for NY2 was 0.5 ng/ml. Furthermore, N-glycosylated human rlL-6 was also bound to YB3 on ELISA. On the other hand YB-3 furtherly recognized N-glycosylated human rlL-6 by sandwich ELISA method. These mAbs may be of use to diagnose the gynecopathy which contains abortion and preterm labor.

Tethered cord syndrome is one of the spinal dysraphism with low-lying conus medullaris frequently associated with spinal lipoma, diastematomyelia and thick filum. The clinical manifestation is variable from no overt symptoms for a long time to back pain, scoliosis, progressive neurological deficit of legs and incontinence. Therefore the diagnosis requires a strong clinical suspicion and aggressive investigation. We experienced a case of 1 day-old male infant who was presented with small soft mass on sacral area. Spinal ultrasonography and spine MRI revealed tethered cord associated with intradural lipoma. We reported a case of tethered cord syndrome with brief review of literatures.

PURPOSE: Parenchymal iron deposition occurs in hemochromatosis, while iron is deposited in reticuloendothelial cells after blood transfusions(Hemosiderosis). We stuided correlation between MR finding and clinical findings(serum ferritin, TSI, LFT, disease duration) of hemosiderosis. MATERIALS AND METHODS: 12 patients with chronic renal failure and one patient with aplastic anemia, who have received multiple transfusion, were performed MRI with a 2.0 Tesla unit. RESULTS: In All of 13 patients(17 cases), the liver revealed low signal intensity equal to background noise. In 4 of 17 cases whose serum ferritin level was below 1000 ng/ml, pancreas, gastric wall, adrenal gland were involved in 1 case. In 4 cases with serum ferritin level between 1000 and 1500, pancreas was involved in 2 cases, and other organ was involved in 1 case. In 9 cases with serum ferritin level above 1500ng/ml, pancreas involved in 9 cases, and other organ in 4 cases. CONCLUSIONS: The MR findings are well correlated with serum ferritin level whereas the TSI, LFT, disease duration are not correlated with involved organ on MR.

OBJECTIVES: To develop a Korean version of VSSS-82 for measuring the multi-dimensional satisfaction with community-based mental health services in psychiatric patients and to investigate both the reliability and validity of the Korean version. METHODS: The VSSS-82 English version was translated and back-translated with some modification. Data from 68 psychosis patients using community-based mental health services in three Community Mental Health Centers (CMHCs) was collected through a personal interview survey regarding the satisfaction and suitability of service. Variability of satisfaction and internal consistency, discriminant validity, and concurrent validity of the VSSS-82 Korean version were evaluated. RESULTS: A higher number of dissatisfied subjects and significant pairwise differences for the dimensions were found. The Crohnbach's alpha coefficient, a measure of internal consistency, ranged from 0.56 (overall satisfaction) to 0.90 (skills and behavior) and significant differences in satisfaction was found in patients by the self-rated suitability of service. CONCLUSIONS: The VSSS-82 Korean version is a reliable and valid instrument for measuring multi-dimensional satisfaction with community-based mental health service.

Korean Journal of Preventive Medicine 1994;27(2):337-365
Rubella is a viral disease with mild constitutional symptoms and generalized rashes ln childhood, it is an inconsequential illness, but when it occurs during early pregnant period, there are significant risks of heart defects, cataract, mental retardation to the fetus. The series of congenital defects induced by rubella is called 'congenital rubella syndrome'. Many research have been performed to find out more effective prevention program on rubella. The objectives of this study are, first, to calculate the incidence rate of acute rubella infection and congenital rubella syndrome in korea, second, to evaluate economic efficiency of several rubella vaccination policies and to offer data for the most reasonable decision on vaccination policy. Study populations are 663,312 children of one year-old in 1992. The author has performed cost-benefit analyses according to the three vaccination policies-U.S.A.'s. U.K's and Sweden's. In this study, the author got the incidence rate of acute rubella infection using the catalytic model. In the meantime, the author used 50 per 100,000 live births as the incidence rate of congenital rubella syndrome. The discount rate used in this study was 5 percent per annum. The sensitivity analyses were done with different discount rates (4%, 7%) and different incidence rate of congenital rubella syndrome (10,100 per 100,000 live births): The study results are as follows: 1. Without vaccination, lifetime expenditures per patient for acute rubella infection amount to 14,822 won and the total expenditures to about 3.1 billion won. Meanwhile, lifetime expenditures per patient for congenital rubella syndrome amount to about 91 million won and the total expenditures to about 16.3 billion won without vaccination. 2. The cost of vaccination for a child of one year old was 2,322 won and the total cost for the one year old children was about 1.5 billion won(American style). The cost for vaccination of female children at fifteen was about 339 million won (British style). And the cost of vaccination at one for both sex and female children at fifteen was about 1.9billion won (Swedish style). 3. The benefit to cost ratios of vaccination or female children at fifteen that is the british mode of rubella vaccination, was 60.0 at the level of 80 % population coverage and 48.6 at 100% coverage. It shows much higher benefit to cost ratio than those of the other two vaccination policies. 4. Both net benefits of vaccination at one (American style) and that of vaccinations at one and fifteen (Swedish style) range from about 17.0 billion to 17.8 billion won, those were larger than that of vaccinations of female children at fifteen(British style, about 16.0 billion). 5. In marginal cost-benefit analysis of only additional program or revaccination, the benefit to cost ratios were 3.6(80% coverage rate) or 0.6 (100% coverage rate). It implies that additional program was less efficient or inefficient 6. In sensitively analysis with different discount rates (4% or 7%) and different incidence rates of congenital rubella syndrome (l0 or 100 per 100,000 live births), the benefit to cost ratios has fluctuated in wide range. However, all the ratios of vaccination of female children at fifteen were higher than those of the others. Even under the most conservative assumption, the benefit to cost ratios of all the rubella vaccination policies were higher than 3.3. In conclusion all the rubella vaccination policies found to be cost-effective and particularly the vaccination of female children at fifteen was strongly recommended.

OBJECTIVES: This is a descriptive study which was carried out to identify characteristics of the chronic mentally ill and their families in a rural area and the influencing factors on family burden. METHODS: Data was collected for seven months beginning April 1, 1998 by questionnaire from chronic mentally ill patients and their families in two towns and seven townships of the rural areas of Kyonggi Province. In additional to the mental diagnosis of the mentally ill patients, family burden was measured by interviewing the other family members using the questionnaire developed by Pai & Kapur (1981). Of those interviewed, 103 patients were selected for final analysis. RESULTS: Of 103 mentally ill patients, 36.1% of the subjects were not under treatment. In particular, of 29 patients with schizophrenia, 48.3% of the subjects had stopped taking medication and 6.9% of the subjects had never been treated. According to the results of a specialized examination by a psychologist, 81% of patients were in need of hospitalization. Most primary caregivers were parents. Of the 101 primary caregivers in the study, 39.6% were over 65 years old. In case of death of the primary caregiver, 50.5% of these 101 mentally ill patients would not have anyone to care for them. Of the various kinds of family burden, primary caregivers most often reported psychological stress. Overall, the families of dementia and schizophrenia patients complained of the most family burden. Through univariative analysis, the variables of sex, education and current treatment type of the patients, the relationship with the patient and marital status of the primary caregiver and the number of people living together in the household showed significant correlation with the family burden of schizophrenia patients. Univariative analysis also showed that there were a number of variables which were correlated to the family burden in mentally retarded patients. Concerning the need for mental health services, the most common requests were for entitlement to disability benefits and housing programs. CONCLUSIONS: Community mental health services in rural areas must be developed, planned and executed in consideration of the local situation. In particular, the development of various family support programs is needed in order to mitigate emotional, mental and economic burdens and carry out a positive role to care for and rehabilitate patients.

Mesothelial cysts have many other names, such as pericardial celomic cyst, pleura-diaphragmatic cyst, simple cyst of the mediastinum, springwater cyst, serosal cyst, etc. (Petereit 1972, Drash 1950). Most mesothelial cysts are believed to originate from malformations of the pericardium, but some, like the one in this case, are believed to result from a pleural malformation. (Ochsner 1966, Lambert 1940). Mesothelial cysts are extremely rare and can be confirmed histologically by special stains. A 64 year old woman was admitted due to a painless bulging mass in her right neck. The operation was performed with the initial diagnosis of cystic lymphangioma confirmed by computer tomography and total excision was possible. The diagnosis of mesothelial cyst of the mediastinum was confirmed by histologic examinations (stainings) and the patient was discharged from the hospital without any significant complications.
