목 적 : 소아 비만은 동맥 경화에 따른 성인 심혈관 질환의 독립적인 위험인자이다. 저자들은 비만 소아들을 대상으로, 동맥경화증의 조기 병변인 경동맥 내막중막 두께가 정상아들에 비해 증가되어 있는지를 확인해 보고자 본 연구를 시행하였다. 방 법 : 총 32명을 대상으로 하였는데, 체질량지수가 연령, 성별 표준치의 85 백분위수 이상인 21명의 비만아/과체중아들을 비만군으로 하였고, 85 백분위수 미만이었던 11명을 정상 대조군으로 하였다. 모든 대상 소아들에서 만성 질환력과 약물 투여력이 없었다. 연령, 성별, 신장, 체중, 수축기/이완기 혈압 등이 조사되었고, 초음파를 통해 경동맥 내막중막 두께가 측정되었다. 19명의 비만아군 환아들에서 혈청 포도당, 간 transaminase 수치, 콜레스테롤 수치 등이 검사되었다. 결 과 : 비만아군의 경동맥 내막중막 두께가 대조군에 비해 증가되어 보였으나 유의한 차이를 보이지는 않았다(0.42 vs. 0.40, P=0.0592). 단순선형회귀분석 결과 체질량지수를 포함하여 경동맥 내막중막 두께의 변화를 통계적으로 의미있게 설명해 주는 변수는 없었으나, 체질량지수가 유의성에 근접하였다(P=0.0585). 결 론 : 소아들을 대상으로 경동맥 내막중막 두께 측정이 연구된 것은 저자들이 조사한 바로는 국내에서 본 연구가 시초의 것으로 생각된다. 통계적 유의성에 근접하였으나 조사 대상수의 부족으로 비만아에서 경동맥 내막중막 두께의 상승이나 체질량지수와의 의미있는 연관성을 증명해 내지는 못하였다. 향후 보다 많은 비만 소아들을 포함한 연구가 후속되어야 할 것으로 판단된다.

This experiment was designed to evaluate the effects of the processing method of common vetch seed (CVS) (Vicia sativa) on laying performance, egg quality, metabolic parameters and liver histopatology during the peak production period in hens. Lohman layers, 46 wk of age in 6 replicate cages each containing 4 hens, were allocated randomly to one of four dietary treatments. Diets were control (C) diet containing no common vetch and experimental diets containing 25% raw common vetch (RCV), 25% soaked in water for 72 h with exchange of water every 24 h (SCV) and 25% soaked&boiled at $100^{\circ}C$ for 30 minute common vetch (SBCV). Inclusion of RCV into the diet deteriorated all laying performance variables. SCV did not alleviate the adverse effect of raw common vetch on feed intake, egg weight, feed conversion, final weight and weight change. SCV partially alleviated egg production (p<0.001). SBCV diminished the adverse effect on feed intake, egg weight, feed conversion, final weight and weight change compared to raw vicia sativa (p<0.001). No significant difference was detected between SBCV and the control group in terms of egg production, feed conversion, final weight and weight change. Regardless of the processing method, all the common vetch groups had lower shell strength compared to the control group. Haugh units did differ between all groups (p<0.001). Inclusion of RCV and SCV into the basal diet decreased triglyceride, cholesterol, total protein and serum glucose concentrations (p<0.001). Hovewer, inclusion of SBCV into the basal diet increased these parameters. Liver samples were stained with Hematoxylin and eosin (HE) and evaluated by light microscopy. A biopsy of native liver tissue was used as a control. No histopathologic finding was present in the control group. Raw V. sativa compared with the control caused lipid accumulations in hepatocytes, severe congestion of hepatic blood vessels, inflammation, increased numbers of Kupffer cells and sinusoidal dilatations. Whereas, the livers from groups given treated V. sativa showed only different degrees of sinusoidal dilatations. Findings from the present study point out the risk of increased hepatic damage due to use of raw Vicia sativa. Increasing treatment of V. sativa lead to a decrease of liver damages. Inclusion of raw and soaked vetch seeds in rations affected adversely all parameters examined in laying hens. But alleviation was observed when soaked and boiled vetch seeds (SBCV) were fed. The results of these experiments indicated that soaked&boiled Vicia sativa seeds may safely be used at a 25% level in rations of laying hens.

Background: This retrospective study was aimed to investigate the efficacy of prophylactic agents in hepatocellular carcinoma (HCC) patients receiving TACE and compare the difference between lamivudine and entecavir. Materials and Methods: A consecutive series of 203 HBV-related HCC patients receiving TACE were analyzed including 91 patients given prophylactic agents. Virologic events, defined as an increase in serum HBV DNA level to more than 1 log10 IU/ml higher than the nadir level, hepatitis flares due to HBV reactivation and progression free survival (PFS) were the main endpoints. Results: Some 48 (69.6%) reached virologic response. Prophylaxis significantly reduced virologic events (8.8% vs 58.0%, p=0.000) and hepatitis flares (1.1% vs 13.4%, p=0.001). Patients presenting undetectable HBV DNA levels displayed a significantly improved PFS as compared to those who never achieved undetectable HBV DNA. Prophylaxis and e-antigen positivity were the only significant variables associated with virologic events. In addition, prophylaxis was the only independent protective factor for hepatitis flares. Liver cirrhosis, more cycles of TACE, HBV DNA negativity, a lower Cancer of the Liver Italian Program score, non-metastasis and no hepatitis flares were protective factors for PFS. Prophylactic lamivudine demonstrated similar efficacy as entecavir. Conclusions: Prophylactic agents are efficacious for prevention of HBV reactivation in HCC patients receiving TACE. Achievement of undetectable HBV DNA levels displayed a significant capability in improving PFS. Moreover, persistent tumor residual lesions, positive HBV DNA and hepatitis B flares might be causes of tumor progression in these patients.

Hyperlipemia is the most leading risk factor of cardiovascular disease which is the main cause of death in Korea. However, there is a tendency to neglect the prevention and treatment since it has no specific symptoms. It has been reported that the level of serum-lipid can be lowered by the improvement of eating habits. Therefore, it is highly likely that the development of programs on the improvement of eating habits through behavioral theory is required to the community nursing practice. The theory of planned behavior, which assumes that human behaviors are determined by one's intention to carry out the behavior, can be characterized by the point that behaviors are not only individual factors but also social behaviors relating to subjective norms. It is widely recognized that this theory has a high predictability on health behavior due to it's simplicity clearness, and measurability as well as high quality of being general. Thus, the theory of planned behavior could be useful in developing a model of a health promotion program to the change of behaviors of the risk group of cardiovascular disease. Consequently, based on the theory of planned behavior, the purpose of this study is to develop an intention promotion program of the diet, and then to testify the effects. The sample of this study consisted of 26 industrial workers who had proved hyperlipemia from a medical examination in 1996 (experimental group 13, control group 13). The intention promotion program, which includes education, monitoring, pressure, counselling on the level of individuals, families and organizations, was conducted for 10 weeks The purpose of this program was to promoting intention of the diet through changes of the prerequisite factors of intention such as behavioral belief, outcome evaluation, normative belief and control belief. When it came to data analysis, the ${\chi}^2$-test and Fisher's Exact test were used to compare the general characteristics between the experimental and the control group, an independent t-test for the other variables. ANOVA was used to the test hypothesis, and the Pearson correlation test for variable's correlation. The results of this study can be summarized as follows ; 1) There was a significant increase in the intention(F=18.51, p=.00) of diet in the experimental group. 2) Diets(F=32.51, p=.001) in the experimental group were better carried out than in the control group. 5) There was a moderate correlation between the intention of diet and performance (r=.587. p=.003). From the results, it can be concluded that the intention promotion program is very effective, leading to the change of health promotion behavior. Above all, it is really valuable that the intention promotion program in this study regards health promotion behavior as a social behavior and that intervention was done on the level of family and organization. Consequently, when performing a health promotion program, social approach elevating the intention should go hand in hand in order to make the program effective.

This study was designed to investigate the effect of increased blood and tibia lead on the change of bone mineral density in retired male lead workers. One hundred nine retired male lead workers who worked in 4 different lead industries and 51 nonoccupationally lead exposed male subjects were recruited from March 2004 to October 2004. Bone mineral density(BMD) was measured by broadband ultrasound attenuation(BUA) at left calcaneous bone area with broadband ultrasound attenuation method of QUS-2(Metra Biosystems Inc, USA). Tibia bone lead was measured for skeletal bone lead with K-xray fluorescence(K-XRF) and blood lead was analyzed with flameless atomic spectrophotometer. Hemoglobin, hematocrit, serum calcium and iron were also analyzed. In addition, information for smoking and drinking status and basic personal data such as age and lead exposure were also collected using questionnaire inquiry. Blood lead was correlated with tibia lead (r=0.711) and these two variables were negatively correlated with BUA in bivariate analysis. BUA and tibia lead showed significant main effects on the change of blood lead after adjusting covariates. The effect modification by the level of BMD (low: lower than the median of BUA and high: higher than the median of BUA) was observed between the association of tibia lead and blood lead after adjustment of covariates. The subjects who had higher BMD seemed to have lower blood lead by the increase of tibia lead than those of lower BMD. In the multiple regression analysis of blood lead and tibia lead on BUA after adjustment of covariates, only blood lead showed statistically significant effect on BUA. This study confirmed that BMD and blood lead were significantly associated. To verify the causal association of BMD on blood lead and vice versa, further longitudinal studies are needed.

The purpose of this study was investigated hypoglycemic effects of fermented red ginseng extracts. We prepared non-fermented red ginseng extracts(R), fermented with Lactobacillus plantarum(RL) extracts, Saccharomycescerevisiae(RS) extracts, and L. plantarum mixed S. cerevisiae(RLS) extracts, examined composition of ginsenosides, SOD-like activity, and $\alpha$-glucosidase inhibitory activity. Ginsenoside Re was highest contents in all extracts, second was ginsenoside Rc and then ginsenoside Rb1. Concentration of these ginsenoside was showed higher in RS than in other extracts. SOD-like activity and $\alpha$-glucosidase inhibitory activity were shown higher in fermented red ginseng extracts than non fermented extracts. And activities of mixed fermentation extracts(RLS) higher than single fermentation extracts(RL, RS). Effects of blood glucose level, serum lipid profile and metabolic variables were evaluated in streptozotocin(STZ) induced diabetic rat. Experimental group was divided into 7 groups: normal control group(hereafter NC group), diabetes control group(DC group), positive control group treated with 50 mg/kg body weight of acarbose(PC group), treated with 300 mg/kg body weight of R, RL, RS and RLS extracts groups, respectively. Blood glucose level of DC group was maintained high level in all experimental period, but treated with red ginseng extracts groups was reduced the glucose level by R group 18.00%, RL group 28.07%, RS group 29.03%, RLS group 42.42%, respectively. The concentration of total cholesterol and triglyceride of fermented red ginseng extracts treated groups (RL, RS, RLS) was lower than non- fermented extracts group(R) DC and PC groups. The activity of ALT, AST in RLS treated groups were lower than other groups.

The diagnosis of iron deficiency rests upon the correct evaluation of body iron stores. Morphological interpretation of blood film and the red cell indices are not reliable and often absent in mild iron deficiency. Serum iron levels and iron-binding capacity are more sensitive indices of iron deficiency, but they are often normal in iron depletion and mild iron deficiency anemia. They are also subject to many variables which may introduce substantial errors and influenced by many pathologic and physiologic states. Examination of the bone marrow aspirate for stainable iron has been regarded as one of the most sensitive and reliable diagnostic method for detecting iron deficiency, but this also has limitations. Thus, there is still need for a more practical, but sensitive and reliable substitute as a screening test of iron deficiency. Pollack et al. (1965) observed that the intestinal absorption of cobalt was raised in iron-deficient rats and Valberg et al. (1969) found that cobalt absorption was elevated in patients with iron deficiency. A direct correlation was demonstrated between the amounts of radioiron and radiocobalt absorbed. Unlike iron, excess cobalt was excreted by the kidney, the percentage of radioactivity in the urine being directly related to the percentage absorbed from the gastrointestinal tract. Recently a test based on the urinary excretion of an oral dose of $^{57}Co$ has been proposed as a method for detecting iron deficiency. To assess the diagnostic value of urinary cobalt excretion test cobaltous chloride labelled with $1{\mu}Ci\;of\;^{58}Co$ was given by mouth and the percentage of the test dose excreted in the urine was measured by a gamma counter. The mean 24 hour urinary cobalt excretion in control subjects with normal iron stores was 6.1% ($1.9{\sim}15.2%$). Cobalt excretion was markedly increased in patients with iron deficiency and excreted more than 29% of the dose. In contrast, patients with anemia due to causes other than iron deficiency excreted less than 27%. Hence, 24 hour urinary cobalt excretion of 27% or less in a patient with anemia suggets that the primary cause of the anemia is not iron deficiency. A value greater than 27% in an anemic subject suggests that the anemia is caused by iron deficiency. The cobalt excretion test is a simple, sensitive and accurate method for the assessment of body iron stores. It may be particularly valuable in the epidemiological studies of iron deficiency and repeated evaluations of the body iron stores.

Background: Severe toxicity is commonly observed in cancer patients receiving irinotecan (CPT-11) UDPglucuronosyltransferase1A1 (UGT1A1) catalyzes the glucuronidation of the active metabolite SN-38 but the relationship between UGT1A1 and severe toxicity remains unclear. Our study aimed to assess this point to guide clinical use of CPT-11. Materials and Methods: 89 cancer patients with advanced disease received CPT-11-based chemotherapy for at least two cycles. Toxicity, including GI and hematologic toxicity was recorded in detail and UGT1A1 variants were genotyped. Regression analysis was used to analyse relationships between these variables and tumor response. Results: The prevalence of grade III-IV diarrhea was 10.1%, this being more common in patients with the TA 6/7 genotype (5 of 22 patients, 22.7%) (p<0.05). The prevalence of grade III-IV neutropenia was 13.4%and also highest in patients with the TA 6/7 genotype (4 of 22 patients; 18.2%) but without significance (p>0.05). The retreatment total bilirubin levels were significantly higher in TA6/7 patients (mean, $12.75{\mu}mol/L$) with compared to TA6/6 (mean, $9.92{\mu}mol/L$) with p<0.05. Conclusions: Our study support the conclusion that patients with a $UGT1A1^*28$ allele (s) will suffer an increased risk of severe irinotecan-induced diarrhea, whether with mid-or low-dosage. However, the $UGT1A1^*28$ allele (s) did not increase severe neutropenia. Higher serum total bilirubin is an indication that patients UGT1A1 genotype is not wild-type, with significance for clinic usage of CPT-11.

Backgrounds : As obesity prevails as an epidemic. diet programs including low-calorie diets are developed continuously. It is generally believed that a low-calorie diet is commonly followed by resting metabolic rate decrease and ultimate weight regain. Ephedra and Evodia are known to have sympathomimetic and anti-obesity effect. Objectives : This study was a prospective, double-blinded, randomized md placebo-controlled clinical trial to evaluate the effects of Ephedra sinica and Evodia rutaecarpa on resting metabolic rate (RMR), weight, body composition, and short-term safety in obese women on low-calorie diet. Methods : 125 otherwise healthy obese women (body mass Index ${\geq}\;25kg/m^2$) were recruited and randomly assigned to three groups: Ephedra group (n=41), Evodia group (n =45), and placebo group (n=39). Subjects were administered Ephedra extract in capsules (pseudo-ephedrine 31.52mg) or Evodia extract in capsules (evodiamine 6.75mg, rutaecarpine 0.66mg) or placebo capsules as well as participating in a low-calorie diet for 8 weeks, Resting metabolic rate and body composition were measured at baseline,4 and 8 weeks. Basic serum exams were performed to evaluate the short-term safety of the herbs and changes of lipid variables. Results : All three groups showed significant BMI decreases probably due to low-calorie diet. Among them, the Ephedra group manifested most prominent BMI-reducing effect and towered total cholesterol and triglycerides significantly. The RMR was not changed during the 8-week diet in all groups. No significant difference among the groups was found in RMR, either. Stbject with higher RMR than the mean at the baseline showed a tendency to keep their RMR more stable during the diet program. Conclusions : Ephedra with a low-calorie diet was effective in reducing BMI. RMR change was not compensated by herbal medicines. RMR change seemed to be affected rather by constitution and body composition than medicine. Ephedra and Evodia were proven to be safe for sort-term use in herbal form. Especially, Ephedra was effective in lowering total cholesterol and triglycerides during the 8 weeks.

Objectives: This study was conducted to investigate the association between sarcopenia and sarcopenic obesity and cardiovascular disease risk in Korean postmenopausal women. Methods: We analyzed data of 2,019 postmenopausal women aged 50-64 years who participated in the Korea National Health and Nutrition Examination Survey in 2008-2011 and were free of cardiovascular disease history. Blood pressure, height, and weight were measured. We analyzed the serum concentrations of glucose, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and triglyceride levels. Waist circumference was used to measure obesity. Appendicular skeletal muscle mass was measured by dual-energy X-ray absorptiometry. Sarcopenia was defined as the appendicular skeletal muscle mass/body weight<1 standard deviation below the gender-specific means for healthy young adults. The estimated 10-year risk of cardiovascular disease risk was calculated by Pooled Cohort Equation. Subjects were classified as non-sarcopenia, sarcopenia, or sarcopenic obesity based on status of waist circumference and appendicular skeletal muscle mass. Results: The prevalence of sarcopenia and sarcopenic obesity was 16.3% (n=317) and 18.3% (n=369), respectively. The 10-year risk of cardiovascular disease risk in the sarcopenic obesity group was higher ($3.82{\pm}0.22%$) than the normal group ($2.73{\pm}0.09%$) and sarcopenia group ($3.17{\pm}0.22%$) (p < 0.000). The odd ratios (ORs) for the ${\geq}7.5%$ 10-year risk of cardiovascular disease risk were significantly higher in the sarcopenic obesity group (OR 3.609, 95% CI: 2.030-6.417) compared to the sarcopenia group (OR 2.799, 95% CI: 1.463-5.352) (p for trend < 0.000) after adjusting for independent variables (i.e., exercise, period of menopausal, alcohol use disorders identification test (AUDIT) score, income, education level, calorie intake, %fat intake and hormonal replacement therapy). Conclusions: Sarcopenia and sarcopenic obesity appear to be associated with higher risk factors predicting the 10-year risks of cardiovascular disease risk in postmenopausal women. These findings imply that maintaining normal weight and muscle mass may be important for cardiovascular disease risk prevention in postmenopausal women.
