Objectives : Bambusae Caulis in Liquamen (BCL) has been used for stamina fortification in Oriental Medicine for thousand years. The goal of the present study was to investigate the muscle antifatigue effect of BCL. Methods : The mice were divided into three groups. The control group was allowed to swim for 10 minutes without BCL infusion. For the preventive effect of BCL, another group referred to BCL-1 was fed with BCL an hour before the swimming exercise. BCL-2 group for the reversion effect was forced to swim for 10 minutes at first, then fed with BCL followed by half an hour rest and another 10 minute swimming exercise. All the serum samples collected by heart puncture were used for the measuring biochemical factors such as LDH, CPK, glucose, lactate, triglycerides and total cholesterol. Results : In the BCL-2 group, lactate and LDH were significantly reduced compared to the control. BCL infusion during the exercise was effective in metabolizing LDH, reducing the conversion ratio of pyruvate into lactate. In the BCL-1 group, it was not effective in antifatigue function. The level of glucose was significantly reduced in BCL-1 group compared to the control. When the BCL was infused before the exercise, it is assumed that glycogenolysis seen during the exercise was prevented. When the BCL was infused during the exercise, the triglycerides and total cholesterol were increased significantly compared to the control. BCL seems to cause the increase of lipolysis to utilize the fat as an energy source. Unlike other parameters, CPK did not show any changes from BCL infusion. Conclusions : Based on the above results, BCL is found to be involved in energy metabolism. Further studies are needed to find out the underlying mechanism of BCL for its effect on stamina fortification.
This study was performed to investigate nutritional effect of various dietary fibers on lead absorption and metabolism of protein and lipid in growing rats. Forty eight male rats of Sprague-Dawley strain weighing 75.7$\pm$0.7g were blocked into six groups according to body weight and fed six kinds of diet different with fiber source(non-fiber, cellulose, pectin) and lead level(0%, 1% ) for 4 weeks. Results are summerized as follows: 1) Food intake, weight gain, FER and PER were remarkably decreased in lead(Pb) added groups, and FER and PER in Pb-added pectin group were significantly lower than those in Pb-added non-fiber group. 2) Weight of liver, kidney and epididymal fat pad, bone weight and length, hematocrit, and hemoglobin content were decreased in Pb-added groups. 3) Total protein content in serum was tended to be decreased in Pb-added groups, but total lipid and cholesterol contents in serum were not different with dietary Pb level and fiber source. 4) Nitrogen, lipid and cholesterol content in liver were tended to be deceased in Pb-added groups, and especially those of the Pb-added pectin group were the lowest among groups. 5) Daily urinary and fecal excretions of nitrogen, lipid and cholesterol were decreased in Pb-added groups. Especially fecal excretions of nitrogen, lipid and cholesterol in Pb-free groups were significantly increased by dietary cellulose and pectin. 6) Pb content in blood was significantly increased in Pb-added pectin group. There was no significant decrease in Pb contents of liver, kidney and tibia, and increase in excretion of Pb by feeding dietary fibers. In conculsion, dietary fibers had no effect on the absorption of Pb, and dietary pectin seemed to increase Pb poisoning by decreasing bioavailibility of protein, lipid and other nutrients in the diet.
Objectives : By examining the effects of Jwa Kum-Whan composed of Coptidis Rhizoma and Evodiae Fructus by the ratio of 6:1 the effects of Soo Ryeon-Whan and composed of Coptidis Rhizoma and Evodiae Fructus by the ratio of 1:1 on hyperlipidemia, the present study attempted to reveal the change of effects based on the ratio of combination. Methods : Jwa Kum-Whan and Soo Ryeon-Whan were injected to rats suffered from induced hyperlipidemia, and then its influence on lipid. During the cultivation of hepatocytes, Jwa Kum-Whan and Soo Ryeon-Whan were added to culture media, and the expression of the enzymes relevant to fat metabolism of hepatocytes was examined. Results : 1. Jwa Kum-Whan significantly decreased total cholesterol(Tc), triglyceride(TG), and LDL-cholesterol(LDLc) of rats suffering from hyperlipidemia induced by high cholesterol diet. Soo Ryeon-Whan decreased LDLc, but had no significant on Tc and TG. 2. Jwa Kum-Whan increased the expression of cholesterol esterase, LDL-receptor, diacylglycerol acyltransferase (DGAT), acylCoA-cholesterol-acyltransferase (ACAT), peroxisome proliferator activated receptor gamma $(PPAR{\gamma})$, peroxisome proliferator activated receptor alpha $(PPAR{\alpha})$ of cultivated hepatocytes. In addition, Soo Ryeon-Whan increased the expression of cholesterol esterase, LDL-Receptor, DGAT, $PPAR{\gamma},\;PPAR{\alpha}$ of cultivated hepatocytes, but had no significant effects on the expression of ACAT. Conclusion : Both Jwa Kum-Whan and Soo Ryeon-Whan were composed of Coptidis Rhizoma and Evodiae Fructus, but the fonner is more effective in hyperlipidemia.
The obstacles for cardiac imaging are motion artifacts due to cardiac motion, respiration, and blood flow, and low signal due to small tissue volume of heart. To overcome these obstacles, fast imaging technique with ECG gating is utilized. Cardiac exam using MRI comprises of morphology, ventricular function, myocardial perfusion, metabolism, and coronary artery morphology. During cardiac morphology evaluation, double and triple inversion recovery techniques are used to depict myocardial fluidity and soft tissue structure such as fat tissue, respectively. By checking the first-pass enhancement of myocardium using contrast-enhanced fast gradient echo technique, myocardial blood flow can be evaluated. In addition, delayed imaging in 10 - 15 minutes can inform myocardial destruction such as chronic myocardial infarction. Ventricular function including regional and global wall motion can be checked by fast gradient echo cine imaging in quantitative way. MRI is acknowledged to be practical for integrated cardiac evaluation technique except coronary angiography. Especially delay imaging is the greatest merit of MRI in myocardial viability evaluation.

This study divides subjects into people with metabolically healthy obesity and those with metabolically unhealthy obesity to identify the physical activities and nutrients influencing adults with obesity. Participants in the sixth Korea National Health and Nutrition Examination Survey conducted from January through December 2013 were selected as the subjects, and an analysis of complex survey samples was conducted with them. It was found that the number of days of a flexibility exercise (Odds ratio (OR)=1.18, 95% confidence interval (95% CI)=1.01-1.38), water intake (OR=1.04, 95% CI=1.01-1.06) and protein intake (OR=1.07, 95% CI=1.02-1.13) for one week were higher in people with metabolically healthy obesity than in those with metabolically unhealthy obesity, while their fat intake (OR=0.99, 95% CI=0.98-1.00)and carbohydrate intake (OR=0.98, 95% CI=0.97-0.99) were lower. Based on the results of this study, it was found that nursing intervention for obesity would need an approach according to the metabolic condition of obesity.

Purpose: Advanced techniques now make it possible to remove considerable amounts of subcutaneous adipose tissue more safely with minimum blood loss. However, few have analyzed the metabolic consequences of liposuction. The purpose of this study was to identify the early effects of the surgical removal of subcutaneous fat on metabolic changes in patients who have undergone liposuction. Methods: Nineteen patients were evaluated from June 2005 to December 2005. Preoperative body weight, serums levels of lipids, apolipoprotein A1, dehydroepiandrosterone(DHEA), uric acid, insulin, and glucose were evaluated. Insulin resistance was determined using the homeostasis model assessment of insulin resistance (HOMA-IR), which is based on fasting glucose and insulin concentrations. All of these data were remeasured in 1 and 4 weeks postoperatively. Tumescent fluid was infiltrated using the superwet technique. The liposuction device used was a $Liposlim^{(R)}$ power-assisted unit. Results: Average volumes of infiltrate and aspirate were 3,268mL and 2,892mL, respectively. Results in 1 week postoperatively demonstrated a significant difference in high-density lipoprotein(HDL) cholesterol, apolipoprotein A1, insulin, and HOMA-IR levels. However, all values were within normal limits and returned to baseline in 4 weeks postoperatively.Conclusion: This study provides little to support the presumed therapeutic effect of liposuction. And, it is unclear whether liposuction can prevent or be used to treat the metabolic complications of obesity. However, the results of the present study lead us to believe that liposuction is a metabolically safe procedure.
This study was conducted to investigate the effect of dietary thyroid hormone (T$_3$and T$_4$) on growth, feed conversion ratio and serum T$_3$or T$_4$concentration of broiler chicks. Zero to six week-old broiler chicks were randomly allocated into seven treatment groups for feeding trials with three replication : control, T$_3$(0.1), T$_3$(1.0), T$_3$(5.0), T$_4$(0.1), T$_4$(1.0), T$_4$(5.0) ppm group. Concentrations of T$_3$and T$_4$in serum were analyzed. The weight gain of T$_3$(1.0), T$_3$(5.0) and T$_4$(5.0) groups were significantly lower than that of control. No statistically significant adverse effect was observed in other groups (p〉0.05). Feed intake was significantly lower in T$_3$(0.1, 1.0 and 5.0) and T$_4$(5.0) than in control group (p〈0.05), and the feed conversion ratio had a similar trend to the feed intake change. The contents of liquid and abdominal fat pad in carcass were significantly decreased in all T$_3$and T$_4$groups (p〈0.05). T$_3$and T$_4$concentration in serum was significantly increased at over 1.0ppm of the hormone supplementation level. As T$_3$addition level increased, T$_4$concentration in serum reduced ; however, T$_3$in serum was directly proportional during fasted were slightly increased when T$_3$or T$_4$was added to broiler diets.

Betaine supplementation has been shown to alleviate altered glucose and lipid metabolism in mice fed a high-fat diet or a high-sucrose diet. We investigated the beneficial effects of betaine in diabetic db/db mice. Alleviation of endoplasmic reticulum (ER) and oxidative stress was also examined in the livers and brains of db/db mice fed a betaine-supplemented diet. Male C57BL/KsJ-db/db mice were fed with or without 1% betaine for 5 wk (referred to as the db/db-betaine group and the db/db group, respectively). Lean non-diabetic db/+ mice were used as the control group. Betaine supplementation significantly alleviated hyperinsulinemia in db/db mice. Betaine reduced hepatic expression of peroxisome proliferator-activated receptor gamma coactivator 1 alpha, a major transcription factor involved in gluconeogenesis. Lower serum triglyceride concentrations were also observed in the db/db-betaine group compared to the db/db group. Betaine supplementation induced hepatic peroxisome proliferator-activated receptor alpha and carnitine palmitoyltransferase 1a mRNA levels, and reduced acetyl-CoA carboxylase activity. Mice fed a betaine-supplemented diet had increased total glutathione concentrations and catalase activity, and reduced lipid peroxidation levels in the liver. Furthermore, betaine also reduced ER stress in liver and brain. c-Jun N-terminal kinase activity and tau hyperphosphorylation levels were lower in db/db mice fed a betaine-supplemented diet, compared to db/db mice. Our findings suggest that betaine improves hyperlipidemia and tau hyperphosphorylation in db/db mice with insulin resistance by alleviating ER and oxidative stress.
Background: Literature is lacking on the effects of feeding by-product feed (BF)-based silage on rumen fermentation parameters, nutrient digestion and nitrogen (N) retention in sheep. Therefore, this study was conducted to determine the effect of replacing rye straw with BF-based silage as a roughage source on ruminal parameters, total-tract apparent nutrient digestibility, and N balance in sheep. Methods: The by-product feed silage was composed of spent mushroom substrate (SMS) (45 %), recycled poultry bedding (RPB) (21 %), rye straw (11 %), rice bran (10.8 %), corn taffy residue (10 %), protected fat (1.0 %), bentonite (0.6 %), and mixed microbial additive (0.6 %). Six sheep were assigned randomly to either the control (concentrate mix + rye straw) or a treatment diet (concentrate mix + BF-based silage). Results: Compared with the control diet, feeding a BF-based silage diet resulted in similar ruminal characteristics (pH, acetate, propionate, and butyrate concentrations, and acetate: propionate ratio), higher (p < 0.05) ruminal NH3-N, higher (p < 0.05) ether extract digestibility, similar crude protein digestibility, lower (p < 0.05) dry matter, fiber, and crude ash digestibilities, and higher (p < 0.05) N retention (g/d) Conclusion: The BF-based silage showed similar energy value, higher protein metabolism and utilization, and lower fiber digestion in sheep compared to the control diet containing rye straw.

The purpose of this study was to investigate the meat metabolite profiles related to differences in beef quality attributes (i.e., high-marbled and low-marbled groups) using nuclear magnetic resonance (NMR) spectroscopy. The beef of different marbling scores showed significant differences in water content and fat content. High-marbled meat had mainly higher taste compounds than low-marbled meat. Metabolite analysis showed differences between two marbling groups based on partial least square discriminant analysis (PLS-DA). Metabolites identified by PLS-DA, such as N,N-dimethylglycine, creatine, lactate, carnosine, carnitine, sn-glycero-3-phosphocholine, betaine, glycine, glucose, alanine, tryptophan, methionine, taurine, tyrosine, could be directly linked to marbling groups. Metabolites from variable importance in projection plots were identified and estimated high sensitivity as candidate markers for beef quality attributes. These potential markers were involved in beef taste-related pathways including carbohydrate and amino acid metabolism. Among these metabolites, carnosine, creatine, glucose, and lactate had significantly higher in high-marbled meat compared to low-marbled meat (p<0.05). Therefore, these results will provide an important understanding of the roles of taste-related metabolites in beef quality attributes. Our findings suggest that metabolomics analysis of taste compounds and meat quality may be a powerful method for the discovery of novel biomarkers underlying the quality of beef products.
