We conducted comparative study on metabolizable energy content of extracts of angelica keiskei and its byproduct. Total six different groups consisting of five test groups treated with angelica keiskei and one control group were compared. Each of the five test groups were given 30% of one of whole plant, extracts, fermented of extracts, byproduct and extracts plus byproduct, respectively, mixed with AIN93M. After 3 days of adjustment period, all groups were subjected to 4 days of test period during which the amounts of feed intake and excretion were measured everyday. All feces were treated for the prevention of decomposition and changes before its energy content were measured using a bomb calorimeter. The amount of excretion was $4.8\;{\pm}\;0.3\;g$/rat/3 days in control group and 9.9-15.0 g/rat/3 days in the groups were added with extracts of angelica keiskei indicating that the angelica keiskei-treated groups produce 2-3 times more excretion. Metabolic energy of control diet was 4,133.3 kcal. This was found to be 15 to 20% higher compared with the metabolic energy content ranging from 3,117.0 kcal/kg (extracts of angelica keiskei) to 3,259.8 kcal/kg (extracts plus byproducts) angelica keiskei-treated groups. This is interpreted as the result of the decreased metabolic energy in the test diets were substituted with 30% of ngelica keiskei-treated ingredient which has low metabolic content itself. One notable finding is that the metabolic content of the group mixed with byproducts and extracts (1,763.0 kcal/kg) is 27% higher than that of extracts of angelica keiskei (1,286.8 kcal/kg) indicating that mechanical grinding increases the rate of digestion and absorption increasing, in turn, the energy content used in the body. The results of analysis of overall caloric absorption showed absorption rate in order of Whole plant < extracts < byproduct < extract plus byproduct < fermented of extract.

This experiment was carried out to investigate the effect of hypoglycemic yogurt as a clinical test with person both who have diabetes and who don't have diabetes. Diabetes is a disease caused by unused and accumulated glucoses produced via the foods digestion due to the lack of insulin or lower tissue reaction to insulin. Patients with diabetes or complications of diabetes are on the rise annually. For the therapy and prevention of diabetes, a yogurt made from functional materials such as insulin-resistant FK-23 lactic acid bacteria, Pinitol, edible fiber which delays glucose-absorption, extract powder of glucose-absorption-inhibitory white bean and low-caloric Erythritol and banaba extract is effective for reduce or restrain the blood glucose levels. The blood glucose levels after a meal of non-diabetic persons were lower after drinking a hypoglycemic yogurt than they after drinking general yogurt. The blood glucose levels after a meal of 10 diabetic patients were checked after drinking the yoghurt. As a result, 19 mg/dL, 30 mg/dL, 31 mg/dL of blood glucose levels decreased in 30 min, 60 min and 120 min respectively after drinking the yogurt. Blood glucose inhibition rates of 80 % of the tested patients also decreased. The blood glucose level of the diabetic patients having drunk the yogurt for 30 days consistently decreased into 59 mg/dL in 120 min after a meal.

Exercise increases the expression and interaction of major neurotrophic factors such as brain-derived neurotrophic factor (BDNF), insulin-like growth factor-1 (IGF-1), and vascular endothelial growth factor (VEGF) at both central and peripheral tissues, which contributes to improved brain and neural plasticity and cognitive function. Previous findings have been to understand the effect of light or moderate intensity aerobic exercise on neurotrophic factors and cognitive function, not that of high intensity aerobic exercise. However, recent findings suggest that high intensity interval training is a safe, less time-consuming, efficient way to improve cardiorespiratory fitness and weight control, thus American College of Sport Medicine (ACSM)’s guidelines for exercise prescription for various adult populations also recommend the application of high intensity interval training to promote their overall health. High intensity interval training also enhances the expression of BDNF, IGF-1, and VEGF at the brain and peripheral tissues, which improves cognitive function. Increased frequency of intermittent hypoxia and increased usage of lactate as a supplementary metabolic resource at the brain and neural components are considered a putative physiological mechanism by which high intensity interval training improves neurotrophic factors and cognitive function. Therefore, future studies are required to understand how increased hypoxia and lactate usage leads to the improvement of neurotrophic factors and what the related biological mechanisms are. In addition, by comparing with the iso-caloric moderate continuous exercise, the superiority of high intensity interval training on the expression of neurotrophic factors and cognitive function should be demonstrated by associated future studies.

Introduction: This study examined the regulatory mechanism underlying the meal-induced changes in the hypothalamic-pituitary-adrenal gland (HPA) axis activity. Materials and Methods: Male Sprague-Dawley rats (250-300 g) were hired for two different experiments as follows; 1) rats received either 8% sucrose or 0.2% saccharin ad libitum after 48 h of food deprivation with the gastric fistula closed (real feeding) or opened (sham feeding). 2). rats received 5 ml of intra-oral infusion with 0.2% saccharin or distilled water after 48 h of food deprivation. One hour after food access, all rats were sacrificed by a transcardiac perfusion with 4% paraformaldehyde. The brains were processed for c-Fos immunohistochemistry and the cardiac blood was collected for the plasma corticosterone assay. Results: Real feedings with sucrose or saccharin and sham feeding saccharin but not sucrose, following food deprivation decreased the plasma corticosterone level. c-Fos expression in the nucleus tractus of solitarius (NTS) of the fasted rats was increased by the consumption of sucrose but not saccharin, regardless of the feeding method. On the other hand, the consumption of sucrose or saccharin with real feeding but not the sham, induced c-Fos expression in the paraventricular nucleus (PVN) of the fasted rats. The intra-oral infusion with saccharin or water decreased the plasma corticosterone level of the fasted rats. Intra-oral water infusion increased c-Fos expression in both the PVN and NTS, but saccharin only in the NTS in the fasted rats. Conclusion: Neither restoration of the fasting-induced elevation of plasma corticosterone nor the activation of neurons in the PVN and NTS after refeeding requires the palatability of food or the post-ingestive satiety and caloric load. In addition, neuronal activation in the hypothalamic PVN may not be an implication in the restoration of the fasting-induced elevation of the plasma corticosterone by oropharyngeal stimuli of palatable food.
In this study, the effects of feeding citrus peel on the nutritional composition of chicken meat were investigated. The samples consisted of chicken meats provided with only feed for laying hens without citrus peel (CP-0), and chicken meats fed with 1.0%, 1.5% and 2.0% citrus peel during the starter (initial period feed; 1${\sim}$9th day), the grower (middle period feed; 10${\sim}$24th day), and the finisher (latter period feed; 25${\sim}$36th day), respectively. There was no significant difference between CP-0 and CP-1 regardless of feeding citrus peel in terms of chicken's moisture, protein, fat, ash or caloric content. The cholesterol content was significantly lower in the CP-1 chicken meats than in the CP-0 chicken meats (p<0.05). The K P and Ca contents were significantly higher in the CP-1 chicken meats than in the CP-0 chicken meats (p<0.05), but there were no significant differences between CP-0 and CP-1, regardless of feeding citrus peet in terms of chicken meat's Na and Mg. There were no significant differences between CP-o and CP-1 regardless of feeding citrus peet in terms of chicken meat's vitamin A, xanthophyll, ${\beta}$-carotene, hesperidin or naringin, but vitamins $B_1$ and $B_2$ were significantly higher in the CP-1 chicken meats than in the CP-0 chicken meats (p<0.05). There were no significant differences between CP-0 and CP-1 regardless of feeding citrus peet in terms of chicken meat's amino acid composition - most of free amino acids and fatty acid composition - but L-glutamic acid was significantly higher in the CP-0 chicken meats than in the CP-1 chicken meats, and the DL-${\beta}$-amino isobutyric acid was significantly higher in the CP-1 chicken meats than in the CP-0 chicken meats (p<0.05).

Raw and cooked pig's head, feet and tails were evaluated for yield, proximate composition, caloric value, and the contents of amino acids, minerals and vitamins. The yields of the raw pig's head, feet and tails were 67.4%, 46.1% and 67.6%, respectively. Corresponding values for the cooked were 54.1%, 34.3% and 47.6% respectively. No significant differences were observed for proximate composition between these samples and any other source3 of the meats. The high energy values, 253.8-310.5 Cal/100 g, of the samples were largely due to the fat content. Among the essential amino acids, these products showed a higher lysine, leucine and threonine content, and lower methionine and tryptophan content. The total amounts of non-essential amino acids were more than half of those of all amino acids. Neither the raw nor the cooked pig's head, feet and tails contained vitamin A. On these data, pig's head, feet and tails tissue have a relatively low in vitamin B content as compared to conventional pork cuts.

The purpose of this study was to determine the efficacy of Aster koraiensis Nakai as a natural health food source. To accomplish this, the general and antioxidative contents of A. koraiensis were measured. Total contents of carbohydrates, crude protein, crude lipid, and ash were 72.15%, 13.49%, 5.09%, and 9.27%, respectively. Caloric content of A. koraiensis was 349.70 kcal, while total dietary fiber was 49.79%. Total proteins consisted of 18 different kinds of amino acids. Contents of essential and non-essential amino acids were 4.6 and 5.5 g/100 g, respectively. Regarding mineral contents, P was the most abundant mineral, followed by K, Ca, and Na. Therefore, A. koraiensis is an alkali material. Total phenol contents of the hot water and 80% ethanolic extracts of A. koraiensis were $87.7{\pm}5.01$ and $112.4{\pm}3.41$ mg GAE/g, respectively. Total flavonoid contents of the hot water and 80% ethanolic extracts were $86.6{\pm}3.71$ and $95.1{\pm}8.00$ mg RE/g, respectively. The DPPH radical-scavenging activity and reducing power of the 80% ethanolic extract of A. koraiensis were higher than those of the water extract. Therefore, the general nutrients and antioxidant bioactive materials in A. koraiensis are potential materials for health foods.
Forty-two percent of the patients with renal failure that requires continuous renal replacement therapy (CRRT) have been reported to have severe malnutrition, and preexisting malnutrition is a statistically significant and independent predictor of negative hospital outcomes. We performed this study to evaluate the appropriateness of the calorie and protein provided for the critically ill patients who require CRRT. One hundred forty-nine patients who received CRRT were enrolled. The demographic data, the length of the ICU stay and the mortality were recorded. The calorie/protein intake and the blood urea nitrogen (BUN), albumin and creatinine levels were used as nutritional parameters. The mean daily calorie intake during CRRT was 16.1${\pm}$7.4 kcal/kg, which was 64% of the recommended intake. Only 10% of the patients received the recommended caloric intake and the ratio of the enteral and parenteral calories was 26%/74%. The mean protein intake was 0.58${\pm}$0.34 g/kg, which was 38% of the recommended intake. The calorie and protein intakes at the termination of CRRT were significantly increased compared to the initial day of treatment, but they stayed under the recommended intake. The BUN, creatinine and albumin levels were significantly increased in the survival group (odds ratio for albumin: 2.73; creatinine: 2.43). A strategy to increase the nutrition provision is needed to improve the nutritional statuses and clinical outcomes of the critically ill patients who require CRRT.
The study was performed to investigate the effects of whey protein-rich meal substitute added with vitamins, minerals, and lactobacillus powder probiotics on weight loss, body fat, and body composition in 24 female volunteers for 4 weeks. Whey protein-rich meal substitute was consumed with low-fat, high calcium milk (1% fat, 260 mg/200 mL) twice a day. Subjects submitted 3-day diet records and a life-style questionnaire before the study. During the study, subjects were required to turn in a diet record every day and consume the meal substitute formula in the metabolic ward at C university for 4 weeks. Anthropometric measurements were carried out weekly by Inbody 7.0. The dietary intake and anthropometric data were analyzed to compare changes before and after the study by paired t-test with SPSS version 23.0. The subjects were mostly early 20's and either overweight or obese and highly motivated to lose weight. Most of the subjects consumed three meals per day regularly and spent mostly 10~15 minutes for a meal. Their caloric intake was relatively low and decreased from 1,360 kcal at week 0 to 1,100 kcal after 4 weeks. However, total protein intake increased while carbohydrate and fat intakes decreased (p<0.05) after the trial. Nine vitamin intakes after the study improved compared to those before the study (p<0.05). After the study, subjects showed lower body weight (-1.8 kg), body fat (-0.94 kg), percent body fat (-0.86%), as well as waist circumference (-4.52 cm), hip circumference (-0.44 cm), waist hip ratio (-0.05), and triceps skinfold thickness (-2.39 mm) compared to those at week 0 (p<0.05). Muscle mass tended to be less compared to week 0, although there was no significant differences between weeks 0 and 4. In conclusion, diet trial with whey protein-rich meal substitute induced weight loss and positively changed body fat parameters and body composition.
This experiment was conducted to verify whether or not chronic consumption of liquor prepared with Gastrodiae rhizoma exhibits antioxidant activity in brain tissue of rats. In the experiment, male Sprague-Dawley rats were given a liquid diet containing 6% (GA6), 18% (GA18), and 36% (GA36) of total calories as liquor for 6 weeks. The control rats (GAC6, GAC18, GAC36) received an isocaloric diet containing Soju instead of liquor. Caloric intakes and body weight gains of the 36% groups were significantly lower than those of the 6% and 18% groups (p<0.05), whereas alcohol intakes were significantly high in the 36% group (p<0.05). MDA contents of plasma and brain showed a positive correlation with alcohol intakes of the liquor and Soju consuming groups. Especially, contents of MDA were significantly higher in the 18% and 36% groups than the 6% group (p<0.05). SOD activities of serum and brain were significantly highest in the 18% group, and they tended to be higher in the liquor consuming groups compared with the control group. Catalase activity of serum showed no significant changes in the three groups consuming liquor, and catalase activity of brain tissue significantly increased in the GA18 group compared with the control group (p<0.05). In the liquor consuming groups, TAC level of serum tended to be higher in the GA36 group compared with the control group (p<0.05). However, TAC level of brain tissue showed no significant changes between the liquor consuming and control groups. These results show that as alcohol intake increased by chronic administration of liquor and Soju, brain tissue of rats was damaged more due to oxidative stress. However, a liquid diet containing 18% of total calories as liquor instead of Soju is expected to have a protective effect on brain damage induced by oxidative stress.
