This study was performed to investigate the term effect of fermented milk in drink on rats fed by cholesterol diet. 150 to 5-week-old male rates of Sprague-Dawley strain weer divided into six groups according to diet and content of fermented milk in drink. The first group served as normal control group fed by synthetic pellets of standard diet. The second , cholesterol control group, was treated with standard diet containing 1% of cholesterol and 500000IU/100g of vitamin D2. The other four groups. fermented milk groups, FM-25,FM-50 , FM 75 and FM-100 were treated with the cholesterol and vitamin D2 diet and supplied with 25%, 50%, 75%, 100% of fermented milk in drink , respectively. The animals were sacrificed for analysis in 3, 6, 9 and 12 months. Weight gain, diet intake , and drink consumption were significantly different among groups. Fermented milk reduced serum cholesterol to a significant effect (p<0.05) and significantly increased the ratio of high density lipprotein cholesterol to total cholesterol(p<0.05). Serum triglycerides were reduced to a smaller and less significant effect in fermented milk group. The aorta and liver of fermented milk showed slighter medial calcification and necrosis and milder fat degeneration than did the cholesterol control group. Supplementation of fermented milk may have a helpful effect on hypercholesteremia and atherosclerosis.

We have studied on the effects of Panax Ginseng on the carbohydrate metabolism of rat. Ginseng does not so much effect on the body weight of the nutrition diet groups, but effects much on the carbohydrate deficient diet groups; it remarkably inhibited the decrease of body weight. Liver glycogen, both in the nutrition and carbohycdrate deficient diet groups, is higher than that of the control. Particularly, the increase of the glycogen is eminent is the nutrition diet-ginseng administered group. In the nutrition diet group, the blood sugar level of ginseng-adminstered rats is the higher, while, in the carbohydrate deficient diet groups, the blood sugar level of ginseng-administered rats is decreased compared with that of control. the oxidation rate of glucose by rat liver slice indicates that only in the carbohydrate deficient diet groups, from the 6th to 15th hour, the oxidation rate of glucose in ginseng-administered group is increased, compared with that of the control. But there is no statistical significance between them. It is thought that Panax Ginseng would effect more on the enzyme system involved in gluconeogenesis and glycogenesis rather than that of carbohydrate oxidation.

Objective: Ramulus mori (RM) has been known to be effective for the treatment of obesity. To show the effectiveness of RM in a more scientific way, RM extract was prepared and evaluated in high fat diet rats by measuring the changes of body weight and lipid metabolism as described briefly below. Methods: 200 g of crushed RM was extracted withmethyl alcohol. The extract was evaporated under reduced pressure to give 33.4 g. For 10 weeks, control group rats were fed a high fat diet, while the test group rats were fed with the same diet plus RM extract. The normal group was fed with a normal diet. 150 mg of RM extract per 1 kg of body weight was added to the diet in the test group rats. Results: The control group rats on the high fat diet gained weight significantly, whereas the test group rats on the high fat diet plus RM extract gamed less weight. The significant increase of liver weight caused by the high fat diet was also inhibited by the RM extract treatment. Total lipid, triglyceride and total cholesterol levels of serum in the high fat diet rats were remarkably increased, whereastheir levels on the high fat diet plus RM extract were less increased. While serum HDL-cholesterol levels were remarkably decreased in the high fat diet, its level was less decreased in the high fat diet plus RM extract. Furthermore, we observed that the activities of hepatic acetyl-CoA carboxylase and fatty acid synthetase increased under the high fat diet, while their activities under the high fat diet plus RM extract were getting back nearly to the normal levels of the normal diet rats. Conclusions: These result show that the obesity caused by a high fat diet was effectively inhibited by an RM extract. Our results also showed that the abnormal lipid metabolism caused by a high fat diet was effectively cured by adding RM extract.

The aim of this experiment was to determine the effect of a high-energy diet on the level of serum metabolites and on carcass characteristics of Hanwoo steers. High energy diets have been used for enhancing intramuscular adipose tissue in high quality beef cattle. However, there is not much information about the physiological reactions to this diet. We hypothesized that a high energy diet would increase blood metabolites and the meat quality of Hanwoo steers during the early and final fattening periods. A $2{\times}2$ factorial arrangement (High, Control, and Early, Final) in a completely randomized design was used to feed 24 Hanwoo steers. Two steers were kept in the same pen and 12 pens were used for the experiment. Blood was drawn from each steer on the first week of every other month from 11 to 28 months. Overall Average Daily Gain (ADG) and feed efficiency were not different between high energy and control diets (p > 0.05). However, Dry Matter Intake (DMI greater with the control diet than DMI with the high energy diet during the final fattening period (p < 0.05). Serum non-esterified fatty acid (NEFA) concentrations were greater in the control diet group than in the high energy diet group during the final fattening period (p < 0.05). However, serum albumin, glucose, total protein, triglyceride, and phosphorus were greater in the high energy group than those of the control group (p < 0.05). Carcass traits or physico-chemical characteristics were not different between high energy diet treatment and the control. These data indicated that a high energy diet (+ 3% TDN) increased serum triglyceride during early fattening periods and decreased non-esterified fatty acids during final fattening periods in Hanwoo steers.

The objective of the study was to investigate the effect of feeding fibrous diets on growth performance and occurrence of aggressive behaviours in growing pigs. Sixty healthy castrated pigs (initial body weight: $46.7{\pm}4.35$ kg) were used. A basal diet was diluted with maize cobs to two levels (0 and 160 g/kg dry matter). Behavioural activities were observed using video cameras for three weeks, 8 h/d starting at 0800 h. Pigs subjected to control diet gained more weight compared to pigs receiving fibrous diet in week 1 (0.47 vs 0.15 kg, respectively) and 2 (1.37 vs 1.04, respectively) (p<0.05). Average daily gain was not affected by treatment diet in the third week. Pigs on high fibrous spent more time eating, lying down, standing, walking and fighting (p<0.05) compared to pigs on control diet. Time spent eating increased as the weeks progressed whilst time spent lying down decreased. Time of day had an effect on time spent on different behavioural activities exhibited by all pigs on different treatment diet (p<0.05). Inactivity was greatest in 5th (1200 to 1300 h) hour of the day for all the pigs on different dietary treatments. Skin lesions appeared the most on neck and shoulder region followed by chest, stomach and hind leg region, and finally head region (p<0.05). Pigs on high fibre diet had more skin lesions in all body regions compared to pigs on control diet (p<0.05). It can be concluded that the high fibrous diet with maize cobs did not affect growth performance and also did not reduce aggressive behaviours. Aggressive behaviours emanated out of frustration when queuing on the feeder. The findings of this study suggest that maize cobs can be included at a level of 160 g/kg in diets of pigs. However, to reduce the level of aggression more feeding space should be provided.

The purpose of this study was to observe the effects of cellulose and pectin on glucose and plasma lipid concentrations in healthy women. Eight female collage students were participated voluntarily. All subjects received a fiber-free control diet (CD), cellulose diet (CED), pectin diet (PTD) with each diet for a period of three days with a 4 day interval. The food intake of subjects were monitored every day and plasma level of glucose, triglyceride, total cholesterol were determined at last day. Blood glucose, plasma triglyceride, total cholesterol were measured at fasting state and 30, 60, 90, 120, and 180 minute after consuming each diet. Plasma glucose concentrations (AUC: Area Under the Curve) of pectin diet was $122.7{\pm}4.0mg/dl$ and that of cellulose diet was $147.6{\pm}8.4mg/d$, but they were significantly lower than in comparison with those of control diet ($197.1{\pm}11.6mg/dl$) (p<0.05) Plasma triglyceride concentrations of the CED ($-83.9{\pm}22.2mg/dl$) PTD ($-9.7{\pm}26.1mg/dl$) showed gradual decrease after each test diet feeding but not significantly different in each dietary fiber added diet (p<0.05). Plasma cholesterol concentrations of the CD was not significantly different in PTD, but PTD was significantly lower than the CED until 3 hours after consuming each test meal (p<0.05). In conclusion, in spite of total cholesterol was reduced only by pectin, glucose and triglyceride were lower than control diet in dietary fiber intake. But there were no significant differences each dietary fiber.

This experiment was conducted to evaluate the effect of supplementing a fat diet with selenium (Se) and vitamin E on performance of cows, blood antioxidant status and milk fatty acid composition. Sixty-three lactating Holstein cows were randomly divided into seven groups of nine cows each and each group was fed one of the following diets: i) a basal diet (control); ii) a basal diet with 0.15 mg Se/kg DM (LSe); iii) a basal diet with 0.3 mg Se/kg DM (HSe); iv) a basal diet with 5,000 IU/cow d vitamin E (LVE); v) a basal diet with 10,000 IU/cow d vitamin E (HVE); vi) a basal diet with 0.15 mg Se/kg DM and 5,000 IU/cow d vitamin E (LSeVE); vii) a basal diet with 0.3 mg Se/kg DM and 10,000 IU/cow d vitamin E (HSeVE). Milk fat percentage and conjugated linoleic acid (CLA) yield in HVE and HSeVE diets increased (p<0.05) compared with the control diet. In milk fat, dietary supplementation of Se tended to increase the proportion of the sum of unsaturated fatty acids (UFA) and significantly decreased (p<0.05) the proportion of the sum of saturated fatty acids (SFA). In addition, compared with the control, thiobarbituric acid reactive substances (TBARS) content was lower and glutathione peroxidase (GSH-Px) was higher when fat diets were supplemented with Se. Our data showed that supplementation with Se and/or VE improved these nutrients in blood and milk. The results indicated that fat diets supplemented with Se improved both antioxidant status in blood and fatty acids in milk fat, and fat diets supplemented with vitamin E alleviated milk fat depression. Therefore, the combination of Se and vitamin E caused synergistic effects on the nutritional quality of milk fat and performance of cows fed a fat diet.

The purpose of this study was to investigate whether nutrition counseling and exercise could be beneficial to patients with acquired cardiac disease (ACD). Twenty-five ACD patients participated in this program, which was based on guidelines for serum lipid management. To measure the effects of the nutrition counseling and exercise education, outpatients with ACD were selected and randomly assigned to three groups which were a control group, a diet only group and a diet and exercise group. Nine diet only group patients and nine diet and exercise group patients received nutrition counseling or nutrition counseling and exercise education every other week. Patients who served as a non counseled control group did not receive any counseling during the same study period. Various markers of disease risk, including lifestyle, anthropometric indices, eating behaviors, and serum lipid levels were measured before and after the program. The program lasted up to 12 weeks, depending on the individuals involved. Database management and statistical analyses were performed using SPSS 7.5 software. As a result, BMI and %IBW showed decreased trends in the diet only and the diet and exercise group. Food habit scores were significantly increased in the diet only group and the frequency of saturated fatty acid, dietary cholesterol, salty food and instant food intake were decreased in the diet only group. Comparisons of the daily nutrient intakes of the groups showed their total calorie, carbohydrate and protein intake had decreased significantly, and also the total fat and dietary cholesterol intake had decreased in the nutrition counseling group. The serum total cholesterol and LDL-cholesterol decreased after 12 weeks in the nutrition counseling group. The diet and exercise group showed less interest in diet control than the diet only group. These results show that a well-planned nutrition counseling program would reduce the risks of ACD and cardiovascular disease and help to care such diseases.

This study classified respondents by degree of obesity using Body Mass Index(BMI) and investigated the differences in self-esteem, food lifestyle, social-cultural attitudes towards appearance, and diet-related attitude and behavior such as trial number of diet, exercise time and period, use of diet information, interest in weight control, diet motivation, and dietetic therapy. A survey was conducted with 258 adults between the ages of 20 and 29 who lived in Daegu and Uijeongbu from November $17^{th}$ to December $14^{th}$ 2014. Data collected from the respondents were analyzed using descriptive statistics, factor analyses, analyses of variance and chi-square tests. This study divided the respondents into three groups (the underweight, the normal weight, the overweight) according to Body Mass Index. The results showed that there were significant differences in food lifestyle (health-conscious, popularity-seeking, taste-seeking), social-cultural attitudes towards appearance, exercise time and period, use of diet information, interest in weight control, diet motivation, and dietetic therapy among groups classified by degree of obesity. However, there were no differences in self-esteem, convenience-seeking, and trial number of diet among them.
