In this study, we evaluated the hypolipidemic and antioxidative effects of biotransformed soybean powder (BTS; Phellinus baumii-fermented soybean) on lipid metabolism in rats. Sprague-Dawley (SD) male rats were divided into basal diet group (BA), high fat diet group (HF), high fat diet containing 10% BTS group (10 BTS), and high fat diet containing 20% BTS group (20 BTS). Changes in the content of various isoflavones, including daidzein and genistein, within the soybean after fermentation to BTS were investigated. The levels of daidzein and genistein were $149.28{\mu}g/g$ and $364.31{\mu}g/g$, respectively. After six weeks experimental period, Food efficiency ratio in the 10 and 20 BTS group was significantly lower than the HF group (P<0.05). Total serum levels of cholesterol, triglycerides, low-density lipoprotein cholesterol, and atherogenic index ratio in the 10 or 20 BTS group were significantly lower than the HF group. The levels of alanine aminotransferase, aspartate aminotransferase and thiobarbituric acid reactive substance were significantly lower in the groups that received 10% and 20% BTS than the HF. The activities of SOD and CAT were significantly higher in the 10 and 20 BTS group than the HF group. The activity of XO in the 10 and 20 BTS group was significantly lower than in the HF group by 20% and 23%, respectively. In conclusion, these data suggest that BTS is an effective agent in improving lipid metabolism and antioxidant enzyme system.

Purpose: In this study, we aimed to evaluate the rarely reported long-term nutritional results of patients with gastric cancer after curative gastrectomy. Materials and Methods: We retrospectively reviewed the prospectively collected medical records of 658 patients who underwent radical gastrectomy with curative intent for gastric cancer from January 2008 to December 2009 and had no recurrences. All patients were followed for 5 years. Nutritional statuses were assessed using measurements of body weight, serum hemoglobin, total lymphocyte count (TLC), protein, albumin, cholesterol, and nutritional risk index (NRI). Results: Patients who underwent total gastrectomy had lower body weights, hemoglobin, protein, albumin, and cholesterol levels. TLC and NRI values after the first postoperative year (P<0.05), and lower hemoglobin and NRI values during the fifth postoperative year than patients who underwent distal gastrectomy (P<0.05). Patients who received adjuvant chemotherapy after gastrectomy had lower hemoglobin, protein, albumin, and cholesterol levels. TLC and NRI values during the first postoperative year, than those who underwent gastrectomy only (P<0.05). Regarding post-distal gastrectomy reconstruction, those who underwent Roux-en-Y had lower cholesterol levels than did those who underwent Billroth-I and Billroth-II reconstruction at the first and fifth years after gastrectomy, respectively (P<0.05). Conclusions: Patients undergoing total or distal gastrectomy with Roux-en-Y anastomosis or adjuvant chemotherapy after surgery should be monitored carefully for malnutrition during the first postoperative year, and patients undergoing total gastrectomy should be monitored for malnutrition and anemia for 5 years.
In order to investigate the effect of dietary zinc and phytic acid levels on enzyme activity and lipid metabolism in rats, male Sprague-Dawley rats, weighing approximately 60-74g, were fed different diets which contained 0, 0.35 or $1.05\%$ phytic acid each at 3 levels of zinc (0, 30 and 1500ppm zinc) for 28 days. Body weight gain, food consumption, and food efficiency ratio were lower in the rats fed a zinc deficient diet (0ppm zinc) than those consuming 30 or 1500ppm dietary zinc. The activities of GOT, GPT and alkaline phosphatase were lower in the rats consuming 30ppm zinc than those fed 0 or 1500ppm zinc diet. The activity of GOT was increased in rats consuming $0.35\%$ phytic acid, whereas that of alkaline phosphatase was decreased in the rats fed phytic acid-containing diet. The concentration of phospholipid in serum was higher in rats fed $0.35\%$ dietary phytic acid, whereas that of liver phospholipid was higher in zinc deficient groups, and increased by addition of dietary phytic acid. The concentration of triglyceride in serum from rats fed 30ppm zinc was lower than those fed 0 or 1500ppm zinc On the other hand, liver triglyceride was higher in both the rats fed 30ppm zinc and $0.35\%$ phytic acid. The concentration of serum total cholesterol was lower in the rats fed 30ppm zinc diet, and it was increased by addition of dietary phytic acid. But liver total cholesterol was higher in 30ppm zinc group. HDL-cholesterol in serum was the highest in both rats consuming 30ppm zinc and $0.35\%$ dietary phytic acid, and the ratio of HDL-cholesterol to total cholesterol was higher in rats consuming 30ppm zinc diet. In conclusion, we suggest that coronary heart disease or liver disease can be prevented with phytic acid in rats which are fed the high zinc diet.
BACKGROUND/OBJECTIVES: In this study, we investigated whether Gelidium amansii extract (GAE) ameliorates obesity in diet-induced obese (DIO) mice. MATERIALS/METHODS: The mice were maintained on a high-fat diet (HD) for 5 weeks to generate the DIO mouse model. And then mice fed HD plus 0.5% (GAE1), 1% (GAE2) or 2% (GAE3) for 8 weeks. RESULTS: After the experimental period, GAE-supplemented groups were significantly lower than the HD group in body weight gain and liver weight. GAE supplemented groups were significantly lower than the HD group in both epididymal and mesenteric adipose tissue mass. The plasma leptin level was significantly higher in the HD group than in GAE-supplemented groups. The leptin level of HD+GAE3 group was significantly lower than that of the HD+conjugated linoleic acid (CLA) group. In contrast, plasma adiponectin level of the HD group was significantly lower than those of HD+GAE2 and HD+GAE3 groups. The expression levels of adipogenic proteins such as fatty acid synthase, sterol regulatory element-binding protein-1c, peroxisome proliferator-activated receptor ${\gamma}$, and CCAAT/enhancer binding protein ${\alpha}$ in the GAE supplemented groups were significantly decreased than those in HD group, respectively. In addition, the expression levels of HD+GAE2 and HD+GAE3 groups are significantly decreased compared to those of HD+CLA group. On the contrary, the expression levels of hormone-sensitive lipase and phospho-AMP-activated protein kinase, proteins associated with lipolysis, were significantly increased in the GAE supplemented groups compared to those in the HD group. HD+GAE3 group showed the highest level among the GAE supplemented groups. CONCLUSIONS: These results suggested that GAE supplementation stimulated the expressions of lipid metabolic factors and reduced weight gain in HD-fed C57BL/6J obese mice.
Baek-kimchi (whitish baechu kimchi) was evaluated for anti-obesity properties and effects on triglyceride (TG) and cholesterol in blood and adipose tissues in rats fed a high fat (20 %) diet, and compared to the similar effects of baechu kimchi. Baek-kimchi does not use red pepper powder but contains higher levels of sliced radish and pear than baechu kimchi. SD rats were raised for four weeks on either a normal diet (ND, based on the AIN-93M diet), high fat diet (HFD, supplemented with 16% lard oil in the ND), or HFD containing 5 % baek-kimchi or 5 % baechu kimchi. Feed consumption was not different among the groups, but weight gains were significantly lower in the groups fed either the normal diet or HFD with baek-kimchi or baechu kimchi diets than the group fed HFD alone. The weights of liver and epididymal and perirenal fat pads in baek-kimchi and baechu kimchi diet groups were lower than those of the HFD groups, but the baek-kimchi diet group had lower epididymal and perirenal fat pad weights than the baechu kimchi diet group (p<0.05). The baechu kimchi dietary group also had significantly lower triglyceride and cholesterol contents in liver and epididymal and perirenal fat, reversing the higher levels seen in HFD. Baek-kimchi and baechu kimchi diets were also effective in lowering serum triglyceride and cholesterol levels (p<0.05). These results suggest that baek-kimchi and baechu kimchi consumption can reverse the effects of HFD on weight gain and blood and tissue lipids, and that baek-kimchi is more effective than baechu kimchi. The greater effect is probably due to the higher content of radish and pear used in baek-kimchi.

Objective: An experiment was conducted to evaluate the effect of different levels of crude protein (CP) and two rearing systems (cage and floor), on blood parameters and digestive and reproductive organ development of brown laying hens. Methods: A total of 400 Hisex Brown laying hens between 30 and 45 weeks of age were distributed in a completely randomized design and a 2×4 factorial arrangement, with main effects including two rearing systems (cage and floor) and levels of CP (140, 150, 160, and 180 g/kg), in a total of eight treatments and five replicates of 10 birds each with initial body weight of 1,877 g (laying hen in cage) and 1,866 g (laying hens in floor). The parameters evaluated were plasma total protein, albumin, uric acid, total cholesterol, relative weights of oviduct, abdominal fat, liver, gizzard, crest and dewlap, length of small intestine and oviduct. Results: The blood parameters were similar in birds reared in cage and floor systems. The birds reared on the floor showed greater small intestine and oviduct weight (%) and lower liver and pancreas weight (%). A significant interaction was observed between factors for the relative gizzard, crest and dewlap weight, serum protein, uric acid, and total cholesterol (p<0.05). The diets with 140 g/kg CP resulted in lower serum protein and lower cholesterol in birds reared in floor system, while birds reared in cage system showed no effect of CP on both parameters. Birds reared in cage and fed with 140 and 150 g/kg CP presented lower uric acid. The group of birds reared in floor system fed 180 g/kg had greater uric acid. Conclusion: The dietary protein level can be reduced up to 140 g/kg for Hisex Brown hens (30 to 45 weeks of age) without an important effect on metabolic profile and organ development in both rearing systems.

𝛼-MnO2 as a cathode material for Zn-ion batteries allows insertion and extraction of Zn ions within its tunnel structure during charge and discharge. The morphology and crystal structure of 𝛼-MnO2 particles critically determine their electrochemical behavior and energy storage performance. In this study, 𝛼-MnO2 was synthesized from precursor solutions under varying pH conditions using a hydrothermal method. The effects of pH values on the morphology, crystal structure, and electrochemical performance were systematically analyzed. The analysis revealed that materials synthesized at higher pH levels exhibited elongated and narrow nanorods with a lower specific surface area. In contrast, those formed at lower pH levels showed shorter, thicker nanorods with a higher specific surface area. This increased surface area at a lower pH enhanced the specific capacitance by providing a greater electrode/electrolyte interfacial area. By contrast, the material synthesized at higher pH conditions demonstrated superior rate capability, attributed to its crystal structure with wider lattice spacings. Wide lattice parameters in the material synthesized at higher pH conditions facilitated easier ion transport than at lower pH levels. Consequently, the study confirms that adjusting the pH of the precursor solution can optimize the electrochemical properties of 𝛼-MnO2 for Zn-ion batteries.
This study investigated the effects of protease treatments (trypsin, chymotrypsin, and pepsin) under various pressure levels (0.1-300 MPa) for the characteristics of porcine placenta hydrolysates. According to gel electrophoretic patterns, the trypsin showed the best placental hydrolyzing activity followed by chymotrypsin, regardless of the pressure levels. In particular, the peptide bands of tryptic-digested hydrolysate were not shown regardless of applied pressure levels. The peptide bands of hydrolysate treated chymotrypsin showed gradual decreases in molecular weights ($M_w$) with increasing pressure levels. However, the pepsin did not show any evidences of placental hydrolysis even though the pressure levels were increased to 300 MPa. The gel permeation chromatography (GPC) profiles showed that the trypsin and pepsin had better placental hydrolyzing activities under high pressure (particularly at 200 MPa), with lower $M_w$ distributions of the hydrolysates. Pepsin also tend to lower the $M_w$ of peptides, while the major bands of hydrolysates being treated at 300 MPa were observed at more than 7,000 Da. There were some differences in amino acid compositions of the hydrolysates, nevertheless, the peptides were mainly composed of glycine (Gly), alanine (Ala), hydroxyproline (Hyp) and proline (Pro). Consequently, the results indicate that high pressure could enhance the placental hydrolyzing activities of the selected proteases and the optimum pressure levels at which the maximum protease activity is around 200 MPa.

Purpose: The aim of the present study was to investigate the risk factors for the development of coronary artery lesions (CALs) and to determine whether hyponatremia is associated with CALs in children with Kawasaki disease (KD). Methods: We retrospectively analyzed the data of 105 children with KD who were admitted to Ilsan Hospital between January 2000 and July 2011. Results: Erythrocyte sedimentation rate (P = 0.013), total bilirubin levels (P = 0.017) were higher and serum sodium levels (P = 0.027) were lower in KD children with CALs than those without. White blood cell (WBC) counts (P = 0.006), neutrophil counts (P = 0.003) were higher and albumin levels (P = 0.009) were lower in KD children with hyponatremia than those without. On multiple logistic regression analysis, hyponatremia (P = 0.024) and intravenous immunoglobulin-resistance (P = 0.024) were independent risk factors for CALs in KD. Furthermore, serum sodium levels were correlated negatively with WBC counts (P = 0.004), neutrophil counts (P < 0.001), total bilirubin levels (P = 0.005) and positively with albumin levels (P = 0.009). Conclusion: Our study indicates that hyponatremia may reflect severe inflammation in children with KD.
Purpose: Fractional exhaled nitric oxide (FeNO) and forced expiratory flow between 25% and 75% of vital capacity ($FEF_{25-75}$) are not included in routine monitoring of asthma control. We observed changes in FeNO level and $FEF_{25-75}$ after FeNO-based treatment with inhaled corticosteroid (ICS) in children with controlled asthma (CA). Methods: We recruited 148 children with asthma (age, 8 to 16 years) who had maintained asthma control and normal forced expiratory volume in the first second ($FEV_1$) without control medication for ${\geq}3$ months. Patients with FeNO levels >25 ppb were allocated to the ICS-treated (FeNO-based management) or untreated group (guideline-based management). Changes in spirometric values and FeNO levels from baseline were evaluated after 6 weeks. Results: Ninety-three patients had FeNO levels >25 ppb. These patients had lower $FEF_{25-75}$ % predicted values than those with FeNO levels ${\leq}25$ ppb (P<0.01). After 6 weeks, the geometric mean (GM) FeNO level in the ICS-treated group was 45% lower than the baseline value, and the mean percent increase in $FEF_{25-75}$ was 18.7% which was greater than that in other spirometric values. There was a negative correlation between percent changes in $FEF_{25-75}$ and FeNO (r=-0.368, P=0.001). In contrast, the GM FeNO and spirometric values were not significantly different from the baseline values in the untreated group. Conclusion: The anti-inflammatory treatment simultaneously improved the FeNO levels and $FEF_{25-75}$ in CA patients when their FeNO levels were >25 ppb.
