Objectives: This study was designed to examine the effect of Hominis Placenta Pharmacopuncture on the change in behavior, sleep-related hormones, inflammatory cytokines, anti-oxidants, weight, blood, and serum on rats given chronic physical stress. Methods: Wistar rats older than age 10 weeks were used in this experiment. They were divided into six groups. The normal group was not given stress. The control group was given only chronic physical stress and no treatment. The positive control group was given chronic physical stress and treated with zolpidem. Three Hominis Placenta Pharmacopuncture (HPP) groups were given chronic physical stress, then treated with different concentrations of HPP; HPP-0.5× (0.5 times diluted), HPP-1× (undiluted) and HPP-2× (2 times condensed). The changes of values of Nestlet Shredding results, weight, Melatonin, Gamma-aminobutylic Acid (GABA), Tumor Necrosis Factor Alpha (TNF-α), Interleukin-6 (IL-6), Superoxide dismutase (SOD), glutathione peroxidase (GPx), AST, ALT, BUN, Creatinine, and leukocytes were observed during the experiment. Results: The changes in chronic physical stress of the rat model were as follow. The Nestlet Shredding result increased in the control group compared to the normal group (p<0.05), and decreased in the HPP-1× and HPP-2× compared to the control group (p<0.05). The amount of weight gain showed increasing tendency in the HPP-2× compared to the control group since the second week. The GABA increased (p<0.05) and Melatonin also showed certain increasing tendency in the HPP-1× and HPP-2× compared to the control group. The TNF-α and IL-6 increased in the control group compared to the normal group (p<0.01), and decreased in all the HPPs compared to the control group (p<0.05). The SOD level decreased in the control group compared to the normal group (p<0.01), and increased in all the HPPs compared to the control group (p<0.05). GPx, AST, ALT, Bun, Creatinine and leukocytes showed no noticeable difference among all groups. Conclusions: Hominis Placenta Pharmacopuncture was effective in increasing weight, GABA, Melatonin, SOD, and decreasing Nestlet Shredding and inflammatory cytokines, suggesting that it consequently facilitates in relieving physical stress.

The enhancement to the back-propagation algorithm presented in this paper has resulted from the need to extract sparsely connected networks from networks employing product terms. The enhancement works in conjunction with the back-propagation weight update process, so that the actions of weight zeroing and weight stimulation enhance each other. It is shown that the error measure, can also be interpreted as rate of weight change (as opposed to ${\Delta}W_{ij}$), and consequently used to determine when weights have reached a stable state. Weights judged to be stable are then compared to a zero weight threshold. Should they fall below this threshold, then the weight in question is zeroed. Simulation of such a system is shown to return improved learning rates and reduce network connection requirements, with respect to the optimal network solution, trained using the normal back-propagation algorithm for Multi-Layer Perceptron (MLP), Higher Order Neural Network (HONN) and Sigma-Pi networks.

This study was performed to investigate the effect of a raw diet (RD) on blood glucose and immune function in non-diabetic (normal) and streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were assigned to four groups (normal control, normal RD, diabetic control and diabetic RD). The control groups and the RD groups were fed an AIN-diet and RD for four weeks, respectively. Weight gain was statistically lower in the RD groups than in the controls. Fasting plasma glucose was significantly lower in the diabetic RD group than in the diabetic control group. The $CD4^+$ T-cell population was higher along with the $CD4^+/CD8^+$ ratio of the mesenteric lymph nodes in the normal RD group compared to the other groups. It can be concluded that RD may reduce the plasma fasting glucose concentration in diabetic rats and improve mesenteric lymph node immune function in normal rats.

Because of the problem of increasing self-weight due to the enlargement and high-rise of buildings using normal aggregate concrete, the need for structural lightweight aggregate concrete increases. However, early strength prediction is required when placing structural lightweight aggregate concrete, but research is insufficient. In this study, the ultrasonic pulse velocity of normal aggregate concrete and lightweight aggregate concrete was measured at early age. As a result, the ultrasonic pulse velocity of lightweight aggregate concrete was lower than normal aggregate concrete according to elapsed time at early age.

In this study, we compared corn gluten hydrolyzates, BCAAs, and leucine for their effects on body weight reduction in high fat-induced obese rats in order to determine the major active components in the corn gluten hydrolyzates. After obesity was induced for 13 weeks with high fat diet, the overweight-induced SD rats (n = 64) were stratified according to body weight, randomly blocked into eight treatments, and raised for 8 weeks. Four groups were changed to a normal diet and the other groups remained on the high fat diet. Each of the groups within both diets was fed either casein, corn gluten hydrolyzates, leucine, or branched chain amino acids, respectively. Daily food intake, body weight gain, and food efficiency ratio were significantly lower in the corn gluten hydrolyzate groups compared to the other groups, regardless of the high fat diet or normal fat diet. The rats fed the corn gluten hydrolyzates diet had the lowest perirenal fat pad weights whereas muscle weight was significantly increased in the corn gluten hydrolyzates groups. Plasma triglyceride, hepatic total lipid, and total cholesterol contents were significantly reduced in the corn gluten hydrolyzates groups. Other lipid profile measurements were not significantly changed. Plasma triglyceride and hepatic total lipid were also significantly reduced in the BCAA and leucine groups. Leptin levels were significantly lower and adiponectin was significantly higher in the corn gluten hydrolyzates groups. Fasting blood glucose, insulin, C-peptide, and HOMA-IR levels were also significantly reduced in the corn gluten hydrozylates groups, regardless of fat level.

The present study evaluated the effect of various dosages of soybean isoflavone extract on body weight changes, glucose tolerance and liver function in streptozotocin-induced diabetic rats. One group of normal rats (normal control) was fed an AIN-76-based experimental diet and four groups of diabetic rats were fed the same diet supplemented with four different levels of soybean isoflavone extract for seven weeks. The daily dosages of pure isoflavone for four diabetic groups were set to be 0 mg (diabetic control), 0.5 mg (ISO-I), 3.0 mg (ISO-II) and 30.0 mg (ISO-III) per kilogram of body weight, respectively. The daily consumption of isoflavone at the level of 3.0mg per kilogram of body weight resulted in the suppression of body weight loss and increased the survival rate of diabetic animals one and half times compared to that of the diabetic control group. Blood glucose levels in a fasting state and after the oral administration of glucose were significantly lower in the ISO-II group during the oral glucose tolerance test. The ISO-II group showed a tendency to elongate the gastrointestinal transit time. The activity of serum aminotransferases, indicator of liver function, was not negatively affected by any intake level of isoflavone. The present study demonstrated that the soybean isoflavone extract may be beneficial to diabetic animals by improving their glucose tolerance and suppressing weight loss without incurring hepatotoxicity at the daily dosage of 3.0 mg per kg of body weight.

Objectives The purpose of this study is to evaluate the current growth via Growth indices, Obesity indices, Metabolic risk factors of Multicultural Families' Children in Dae-jeon area. Methods 5 to 12 year old children from 56 multicultural families were enrolled in this study, and were examined their bone age and body composition, and have received blood tests. Results 1. In Growth indices, average height percentile was $53.64{\pm}25.59%$. The AHP and MPH respectively, were converted into 20 years old adult height percentile, AHP of a girls was 40 percentile and MPH was 19 percentile, AHP of boys was 57 percentile and MPH was 21 percentile. 2. In Obesity indices, average of BMI pecentile was $44.16{\pm}29.52$; low-weight group (6 boys, 4 girls), normal-weight group (20 boys, 18 girls), over-weight group (8 girls). Average PWH was $100.51{\pm}15.66%$; low-weight group (9 boys, 5 girls), normal-weight group (14 boys, 15 girls), over-weight group (3 boys, 5 girls), obesity group (5 girls). 3. The results of the relationship between Growth indices and Obesity indices, 1) As RH percentile in boys was increased, skeletal maturity, AHP and AHP-MPH were also increased. Similarly, as RH percentile in girls was increased, skeletal maturity, AHP and AHP-MPH were also increased. 2) As skeletal maturity in boys was increased, BMI percentile was also increased. As skeletal maturity in girls was increased, AHP-MPH was decreased but had no significant differences. Conclusions Current growth of children in multicultural families was above the average when compared to that of average children in the same age. It was predicted that the boys' height were still above the average adult height, but the girls' height were below the average. Also this study showed that girls were more prone to be overweight than boys, thus requiring more intensive management and training in regards to eating habits and exercise.

This study investigated the effect of raw soybean yellow(RSY) and raw soybean black(RSB) on body weights, pancreas weights, serum glucose and lipid concentrations of boty normal and diabetic male rats(Sprague-Dawley, body weight 338.8$\pm$19.2g). For each experimental, some rats were injected with streptozotocin intraperitoneal(i.P.) to induce diabets, and other rats were injected with buffer i.P. as a control group. Body weight gain(BWG) was lower in rats fed both RSY and RSB diet(3.4~5.0g BWG) than in those fed control diet(58.1g BWG). The diabetic rats showed significant decrease of bo요 weight (-50~-67g) compared with the control rats. RSY and RSB feeding resulted in greater pancreatic weight relative to body weight, and diabetic rats fed RSY and RSB had heavier pancreatic weights relative to body weight than control rats. The levels of fasting serum glucose in diabetic rats fed both RSY and RSB decreased by 42 and 31%, respectively, compared with the diabetic control rats, but they increased by 80 and 110% compared with the normal control rats. The concentrations of total lipid, triglyceride, phospholipid and total cholesterol in serum of diabetic rats fed RSB diet were lower than those in control rats, but serum HDL-cholesterol, HDL-cholesterol/total cholesterol ratio were not affected by raw soybeans feeding. Atherogenic index wa lower in diabetic rats fed RSY and RSB diet than those in control rats. The concentrations of total lipid, triglyceride and phospholipid in liver were lower in raw soybean groups than those in control group. The concentrations of cholesterol in liver of groups treated raw soybean were decreased compared with the control group.

Maintaining adequate fluid balance is essential for all biological functions in the body. The purpose of this study was to evaluate vulnerability to dehydration by analyzing age, gender, body mass index (BMI), and blood lipid parameters in health checkup examinees who visited Sahmyook Seoul Hospital for comprehensive health checkups. In a binary logistic regression analysis stratified by age and body mass index the odd ratio for dehydration was as high as 3.317 (95% CI: 1.666~6.605) in the 50s age group, 4.224 (95% CI: 2.038~ 8.755) in the 60s age group, and 4.610 (95% CI: 1.943~10.940) in the above 70s age group compared to 20s reference age group. Aged females showed greater vulnerability to dehydration with significance levels of P<0.01 and P<0.001. Compared to a normal weight (BMI: 18.5~22.9) the odd ratio was higher in males with an under weight (BMI: less than 18.5) (5.130 [95% CI: 1.631~16.132]) and in females with an over weight (BMI: 23.0~24.9) (1.500 [95% CI: 1.065~2.114]). In conclusion, our results showed that vulnerability to dehydration increased with age and was higher in under weight males and over weight females than that in normal weight.
