Background: An imbalance in energy intake and expenditure can cause obesity, which is a major risk factor for chronic diseases such as heart disease, type 2 diabetes, insulin resistance, cancers and hyperlipidemia. Methods and Results: In this study, we evaluated the anti-obesity effects of a water extract from the young leaves of barley sprout (BS) in 3T3-L1 cells and in high-fat diet (HFD)-induced obese mice (HF). Lipid accumulation measurement indicates that BS markedly inhibited adipogenesis by reducing lipid droplet production in a dose-dependent manner. Furthermore, the mRNA expression of adipogenic transcription factors peroxisome proliferator-activated receptor-${\gamma}$ and fatty acid synthetase, CCAAT/enhancer binding protein-${\alpha}$ and fatty acid binding protein 4 in 3T3-L1 cells was significantly inhibited by BS treatment. In an in vivo test, the BS-administered group of HFD-induced mice showed less body weight gain, and lower liver and epididymal white adipose tissue weights. The BS-treated mice showed decreased serum levels of leptin and lipids compared to untreated HFD mice and the levels of adiponectin and the HDL-cholesterol/total cholesterol ratio increased. These results indicate that BS inhibits body fat accumulation by reducing the mRNA expression of lipogenesis transcription factors and increasing serum adipokine concentration in in vitro and in vivo tests. Conclusions: BS reduced high fat diet-induced weight gain and had a positive effect on dyslipidemia.

Background: Thyroid hormones (TH) are regulated by the hypothalamic-pituitary axis, which plays an important role in cell growth, differentiation, development and other aspects of metabolism. It is believed that an active hypothalamic-pituitary axis increases the susceptibility of thyroid dysfunction during systemic chemotherapy. In order to investigate the relation between thyroid function and chemotherapy the present study was designed to investigate TH in breast cancer patients receiving at least three cycles of chemotherapy. The levels of TH were measured at the baseline and before each cycle of chemotherapy. Materials and Methods: Blood samples for estimation of TH levels were collected from 80 (pre-menopausal-40; post-menopausal-40) breast cancer patients just before they were undergoing - $1^{st}$, $2^{nd}$, $3^{rd}$ and $4^{th}$ cycle of chemotherapy. The serum was separated and $T_3$, $T_4$ and TSH levels were determined by chemiluminescence method. Results: $T_3$ and $T_4$ were found significantly decreased and TSH was found significantly increased after $1^{st}$ (p<0.001), $2^{nd}$ (p<0.0001) and $3^{rd}$ cycle of chemotherapy (p<0.0001). The variation of $T_3$ levels (decreased) and TSH levels (increased) was found more in post-menopausal (p<0.0001) women then in pre-menopausal women after $3^{rd}$ cycle of chemotherapy as compared to baseline (p<0.001). Conclusions: TH were remarkably altered after each cycle of chemotherapy leading to decline in thyroid function of breast cancer patients. Further, the results also indicated that post-menopausal women were more prone towards decline in thyroid function then pre-menopausal women. The present study proposes the monitoring of TH after each cycle of chemotherapy in breast cancer patients.

This experiment was conducted with male chicks to investigate the influence of hormones and nutrients on the development of fatty liver syndrome (FLS) as well as the effects of dietary lipotropic factors on hepatic fat accumulation and lipogenic enzyme gene expression. A total of two-hundred sixteen 4-wk-old Hy-Line male chicks were divided into six groups and fed an experimental diet (T1, low-energy diet with low levels of lipotropic factors; T2, high-energy diet with low levels of lipotropic factors; T3 and T5, low-energy diet with high levels of lipotropic factors; T4 and T6, high-energy diet with high levels of lipotropic factors) for six weeks. The chicks in T5 and T6 groups were treated with intramuscular injections of estradiol benzoate for three days prior to biopsy and clinical analysis of FLS. Chicks treated with estrogen had significantly greater liver weights than untreated chicks. The abdominal fat contents were increased in chicks consuming high-energy diets as compared to those consuming low-energy diets. Treatment with estrogen significantly increased the concentrations of serum cholesterol, triacylglycerol and phospholipid (p<0.05). The hepatic triacylglycerol levels were tenfold higher in the estrogen treated chicks than in the untreated chicks. There were no significant differences in malondialdehyde levels between the treatment groups. Estrogen treatment dramatically increased the levels of fatty acid synthetase, acetyl-CoA carboxylase and ApoB mRNA. The results indicated that treatment with exogenous estrogen in growing male chicks induced hepatic fat accumulation, which might be partially due to increased lipogenic enzyme gene expression.

This study was conducted to investigate feeding effects of the high pressure boiled extracts (HPBE) of the Ogol chicken with herbs on glucose, hormones and immunological response (cytokine, specific antibody) of serum in the rat which fed either with normal feed (T$_1$), normal feed + herb HPBE (T$_2$), normal feed + Ogol chicken HPBE (T$_3$), normal feed + mixture of cross-bred Ogol chicken HPBE (T$_4$) hydrolyzed with Flavourzyme 0.1% for 35 days. During experimental period, there was a weak trend to have a higher glucose content for the T$_4$ group with 102.27${\pm}$5.95 mg/dL, but it was not significantly higher than other treatments. For insulin level, T$_1$ group showed numerically a slightly higher level with 6.79${\pm}$4.64 ${\mu}$IU/mL, but the difference was not significant in statistic term due likely to a large variation in comparison with other treatments. The treatments did not significantly alter testosterone level in rat plasma with 1.09, 1.46, 0.98, 1.13 ng/mL in T$_1$, T$_2$, T$_3$ and T$_4$, respectively. T$_4$ treatment increased the aldosterone level to a significantly (p<0.05) higher level (273.33 ng/dL) than other treatments. The extract treated rat showed a tendency in the cortisol level of lower levels than the control group, particularly, it was significantly (p<0.05) lower in T$_3$ group than other groups. T$_3$ and T$_4$ groups showed higher levels for interlukin-4 (IL-4) and anti-BSA IgG in immune cells and plasma. T$_2$, T$_3$ and T$_4$ treatments showed a slightly higher levels in v-interferon (INF-r) than the control, with a greater effect for T4 treatments. These results suggested that HPBE of the cross-bred Ogol chicken hydrolyzed with Flavourzyme increased immunological activity and decreased the concentration of cortisol and aldosterone hormones.

This study examined salty taste acuity and salty taste preference and sodium intake in relation to zinc nutritional status in 2 rural populations in Korea. And we also examined the main food contributors of their sodium intakes. We enrolled 218 adults (66 men and 152 women) from the Kangneung and Samcheok regions in Korea's Kangwon province in our study conducted from December 2011 to February 2012. Participants from each region were divided into 3 groups based on their serum zinc level (T1: lowest, T2: intermediate, T3: highest). We compared the salty taste acuity and preference, Na index (Dish Frequency Questionnaire for estimation of habitual sodium intake), blood pressure, and intakes of nutrients including sodium by 3 groups of serum zinc level. The results were as follows: a higher serum zinc level indicated a lower sodium intake and Na index (P<0.05). The salty taste acuity was considerably higher for participants from the Kangneung region than those from the Samcheok region (P<0.05). And the serum zinc level was significantly higher in participants from the Kangneung region than those from the Samcheok region (P<0.05). We further divided the participants into 2 groups: those who consumed more zinc than the recommended intake (RI) and the others. We compared salty taste acuity and salty taste preference in the 2 groups. The salty taste threshold and palatable salty taste concentrations were lower for the group with a zinc intake above RI than for the group with zinc intake below the RI. However, the difference was not significant. This study confirms that taste function differs depending on zinc nutritional status. In future, it is required to a large-scale, long-term, prospective study on the correlation between zinc intake, serum zinc levels, and taste perception function and blood pressure.

The relation of food and supplemental intake of iron, vitamin E and ascorbic acid and other lifestyle variables to packed cell volume (PCV) and serum vitamin levels was studied in urban and rural (71% Amish) communities. Subjects were interviewed (24-h dietary recalls) on three occasions over 18-months, and blood samples were taken (maximum observations = 442). Mean PCV was lower in rural males (43.3) than in urban males (45.4) despite higher man food iron intake (18.7 and 14.4 mg/day, respectively). Mean meal iron availability was higher at lunch and lower at breakfast and dinner for rural than for urban subjects. Smoking was the number one variable in males and females explaining variance in PCV. Supplemental vitamin E and ascorbate intakes explained the most variance in serum vitamin E and ascorbate levels, respectively. Serum vitamin E was also associated with supplemental ascorbate intake (r=0.29). Serum ascorbate was also associated with food ascorbate intake (r=0.28) and body weight (r=-0.24).

This study was conducted to identify appetite and nutritional status of 48 cancer patients who have been irradiated over 150$\textrm{cm}^2$ on chest or pelvic area over the three-month period. The data were gathered 3 phases, Each from initiation to completion of radiotherapy through the questionnaires of anorexia, the anthropometric and biochemical measures were used such as weight, TSF, MAC, MAMC, serum albumin and hemoglobin, TLC. Using SAS program, data were analyzed by percentage, Mean$\pm$SD, and two-way repeated measures ANOVA. The results were summarized as follows : 1. Eighty five percent(85%) of the subjects were aged from fifties to sixties. Cancers in the chest area occurred in 100% of men, 56% of the all subjects. The other 44% were pelvic cancer and 71% of the pelvic cancer occurred in women. 2. There were no significant differences in the appetite scores by all groups(characteristics). Changes of the appetite score over time were statistically significant by age, sex, cancer areas staging, treatment modality, and radiation dosage (F=4.0, p=.022; t=6.09, p=.003; t=4.90, p=.009; F=3.28, p=.042; t=5.04, p=.0084; t=4.76, p=.011). The appetite score on the 2nd phase (4 weeks after initiating radiotherapy) decreased from the 1st phase (initiating irradiation), and then increased on the 3rd phase (completing irradiation). 3. There were no significant differences in the body weight and MAMC by all characteristics, and no changes in the body weight and MAMC over time. However there were significant differences of TSF, MAC, level of hemoglobin, level of albumin, and TLC by all characteristics during the three phases. TSF of the men and the chest cancer were lower than those of the women and the pelvic cancer (t=73.20, p=.0001; t=22.91, p=.0001). And there was significant difference by cancer staging(F=3.19, p=.050). But there was no change in TSF over time. MAC of the men and the chest cancer were lower than those of the women and the pelvic cancer each(t=9.23, p=.004; t=17.85, p=.0001). But no change in MAC over time. Levels of hemoglobin had significant differences by age, sex and cancer areas; levels of hemoglobin of older than the fifties, men, and chest area were higher than those on the others(F=3.82, p=.029; t=21.75, p=.0001; t=8.71, p=.005). Levels of albumin were significant differences by sex and cancer areas; levels of albumin on women, and pelvic area were higher than those on the others(t=6.34, p=.015; t=15.23, p=.0003). While the levels of hemoglobin were changed over time, levels of albumin were not changed and within normal limit. TLC of the men was higher than women(t=5.05, p=.029). Changes in the level of hemoglobin over time were statistically significant according to sex, cancer areas, and radiation dosage(t=3.49, p=.035; t=3.36, p=.039; t=4.04, p=.021).

In this study, we investigated the effects of obesity index on the risk factors of chronic diseases in obese children. The subjects were male and female children aged 9 to 12. The average obesity index was 147.7$\pm$13.8% in boys and 147.6$\pm$16.5% in girls. The average percentages of body fat was significantly higher in boys(33.9$\pm$5.7%) than in girls(30.7$\pm$4.4%). It was found that 26% of subjects had abnormal serum GOT and GPT values. Percentages of subjects at risk of cardiovascular disease(CVD) based on corresponding criteria of TG, T chol, HDL chol, and LDL chol were 28.6%, 28.6%, 45.5% and 42.7%, respectively. The risk of CVD was increased with the degree of obesity, which was not significant. The AI(atherogenic index) was higher in boys(4.6$\pm$2.3) than in girls(3.6$\pm$1.2). The serum T chol and LDL chol levels of subjects whose mother are in thirties were significantly higher than those of subjects whose mother are in fourties. The T chol levels of subjects who had mother with job were significantly higher compaired to those of subjects who had housewife mother. The results indicated the urgent need of nu tritional management for the obese children to prevent further devel opment of childhood obesity and hyperlipidemia. Based upon this study, devising method and media for the mother nutritional education as well as for the children nutritional education is required for better growth and health promotion of primary school children.

The present study was carried out to develop the better measures for safety of open heart surgery under extracorporeal circulation (ECC) with Heart-Lung-Machine by preventing changes in the concentrations of serum electrolytes during and after ECC. For this purpose, the cocentrations of serum electrolytes were measured before, during, and after ECC in 21 patients with congenital and acquired heart diseases who received open heart surger, - under ECC using Heart-Lung-Machine. Also considered was the development of safety measured by which changes in serum electrolyte concentrations were prevented during and after open heart surgery under ECC. The mean values for serum sodium levels were observed to be ; $13.14{\pm}0.47$mEq./L. for the samples obtained before ECC. $139.59{\pm}0.68$mEq./L. for the samples obtained 10 minutes after ECC and $138.0{\pm}0.68$mEq./L. for the samples obt"ined 24 hours after ECC. These results indicate that serum sodium concentrations were \\'ithin normal range during and until 24 hours after ECC. 2) The concentrations of serum chloride were found to be $105.38{\pm}0.70$105.38$\pm$0. 70 mEq./L. for the samples collected before ECC, $105.07{\pm}1.01$mEq./L. for the Simples collected 24 minutes aiter ECC and $101.95{\pm}1.09$mEq./L. for the samples collectect 24 hours afte ECC. As was tile case with serum sodium levels, no significant changes were observed in serum chloride levels during and 24 hours after ECC. 3)With proper provisions of potassium chloride solution during ECC, the concentrations of serum potassium were found to be $4.22{\pm}0.06$mEq./L. for the samples removed before EeC, $4.06{\pm}0.14$mEq./L. for the samples removed 10 minutes after ECC and $4.39{\pm}0.07$ mEq./L. for the samples removed 24 hours after ECC. 4)The concentrations of serum calcium were also maintained within normal during and after ECC; $9.15{\pm}0.14$mg/dl for the serum collected before ECC, $8.36{\pm}0.21$mg/dI for the serum collected 10 minutes after ECC and $8.47{\pm}0.14$mg/dl 21 hours after ECC. The maintenance of serum calcium level within normal throughout ECC was achieved by parenteral administrations of calcium gluconate as frequent as required. 5) As were the cases with serum potassium and calcium, the concentrations of plasma bicarbonate was regulated within normal range during and after ECC, only when sodium bicarbonate solution was admini"tered parenterally as it was required; $23.7{\pm}0.50$mEq./L. for the serum collected before ECC. $22.33{\pm}1.09$mEq.lL. for the serum collected 10 minutes after ECC and $25.3{\pm}0.96$mEq./L. for the serum collected 24 hours after ECC. The above results indicate tha t during and after ECC serum sodium and chloride levels remined unchanged without any provision of normal saline, while serum potassium, calcium, and bicarbonate concentrations were kept within normal limits only when these ealectrolytes were administered through parenteral routes. With these results it can be concluded that serum potassium, calcium, and bicarbonate levels should be determined as often as possible during and after ECC and that in order to maintain serum electrolyte levels within normal these electrolytes in the forms of potassium chloride, calcium gluconate, and sodium bicarbonate shou'd be given parenterally as they were found to be required.

The usefulness of single, random measurements of serum FSH and LH in the diagnosis of primary amenorrhea by radioimmunoassay was investigated. The 16 patients were divided into 3 groups by the level of serum FSH and LH. The first group with increased level of serum FSH and LH is five patients, all of these are related to the acquired or congenital abnormality of the ovary. Further studies indicated include buccal smear, chromosome analysis, gynecography and laparosocopy. The second group with normal serum FSH and LH is nine patients, four patients of these are related to the developmental anomaly of the Mullerian duct and five patients are undo etermined origin. Further studies indicated include laparoscopy and gynecography. The third group with decreased serum FSH and normal or decreased serum LH is two patients, one of these is related to the pituitary function, isolated FSH deficiency, the other is undetermined origin. Further studies indicated include the pituitary function test, LH-RH stimulation test, skull radiography. Determination of serum FSH and LH levels does not permit a specific etiologic diagnosis of primary amenorrhea. However the serum levels of FSH and LH can be used to differentiate the principal area of the investigation and can be of assistance in choosing more specific testing procedures.
