This study investigated the effect of the powder of the small water dropwort(PSWD) and brewer's yeast(BY) on the liver function and serum lipid metabolism in alcohol-consuming rats. Male Sprague-Dawley rats were fed an AIN-93 diet(control), ethanol plus control(A), ethanol plus PSWD(AS), ethanol plus BY(AB), ethanol plus PSWD and BY(ABS) diet for seven weeks. The feed intake, body weight gain and feed efficiency ratio were the lowest and in the alcohol-consuming groups. The weight of the liver, kidney, spleen and epididymis of the anatomized rats showed positive correlation with the body weight gain. Compared with group A, the content of the lipid in the serum was significantly low in the AS and AB groups. In particular, it was the most effective in the AB group. The GOT, GPT and ALP level in the serum showed a significant difference in the alcohol-consuming groups. Compared with the A group, they showed a significantly low difference in the AS and AB groups. The total cholesterol and triglyceride levels in the liver were similar in all groups. The weight of the feces was significantly different but there was no significant difference in the content of total cholesterol and triglyceride levels in the AS and AB groups. These results suggest that BY and PSWD improve the liver function, and had an effect on reducing the lipid content of the serum and feces of alcohol-consumed rats. In particular, the effect of BY which contained protein, dietary fiber and vitamin B was higher than that of PSWD.

The purpose of this study was to investigate the relationship among nutritional status, serum lipids and leptin of 134 elementary school students with different obesity index residing in Kyunggi-do, Korea. Subjects were assigned to under weight, normal weight or over weight group according to the their obesity index. Their nutritional status, serum lipid and leptin levels were evaluated based on 24-hr dietary recalls, anthropometric measurements and blood analysis. The mean weight, height and obesity index of total subjects was 150.8cm, 45.6kg and 5.4%. The mean % of body fat was higher while LBM and TBW (total body water) were lower in over weight subjects than those of other two groups. Total food, plant protein, carbohydrate, and vitamin C intakes of underweight male students were lower than those of overweight male students. The consumption of total fat was the highest in the female normal weight subjects and the lowest in female overweight subjects. Male students consumed more plant protein and vitamin C than female students. The mean daily intake of vitamin B$_2$, calcium and zinc of all subjects did not meet the Korean RDA. Also, iron intake of female students was lower than the Korean RDA. The mean level of serum leptin was the highest in male and female overweight subjects (p＜0.001). The HDL-cholesterol level was the highest in the underweight group of male subjects (p＜0.05) and in the normal weight group of female subjects (p＜0.001) The serum level of leptin and atherogenic index (AI) of females were higher than those of males. Serum leptin of total subjects had significantly positive correlation with obesity index, weight, SBP, body fat, cholesterol intake, serum triglyceride, and AI. However, serum leptin was negatively correlated with LBM, TBW, intake of plant protein, vitamin B$_1$, vitamin C and serum HDL-cholesterol. Obesity index was also positively correlated with weight, SBP, body fat, serum triglyceride and AI. To summarize the results, the vitamin B$_2$, calcium, zinc, iron and fiber intakes should be supplied to elementary school students, especially those who were overweight. The average serum leptin level of students showed remarkably positive correlation with obesity index, body fat, serum lipids and AI. Also, it was suggested that the serum leptin might be related to the dietary factors like cholesterol, plant protein, vitamin B$_1$ and vitamin C of elementary school students.

This study aimed to evaluate the nutrient digestibility of growing rabbits fed diets with different levels of either Leucaena leucocephala (LLM) or Moringa oleifera (MOLM) leaf meals and also to compare total collection and $TiO_2$ marker methods for estimating digestibility. A total of 30 California growing rabbits ($1.81{\pm}0.19kg$ live weight on average) were randomly distributed into five experimental groups of six rabbits each and were housed in individual cages. The groups were control, 30% LLM, 40% LLM, 30% MOLM, and 40% MOLM. All groups received pelleted diets for two weeks; diets also contained 4 g/kg titanium dioxide as dietary marker. Daily feed intake was recorded during the whole experimental period and total feces were collected daily and weighed individually during four days. The results showed that there were no difference (p>0.05) in feed, dry matter (DM), organic matter (OM), crude protein (CP), digestible energy, and crude fiber (CF) intake between the control group and the other experimental groups. The apparent digestibility values of DM, OM, CP, CF, acid detergent fiber, and gross energy were the highest for control group (p = 0.001), meanwhile MOLM diets had generally higher nutrient digestibility coefficients than LLM diets. Increasing the inclusion level of leaf meal in the diet from 30% to 40% improved the digestibility of CF from 45.02% to 51.69% for LLM and from 48.11% to 55.89% for MOLM. Similar results for apparent nutrient digestibility coefficients were obtained when either total collection or indigestible marker method was used. In conclusion, the digestibility of MOLM containing diets were better than LLM diets, furthermore $TiO_2$ as an external marker could be used as a simple, practical and reliable method to estimate nutrients digestibility in rabbit diets.

On the basis of the increasing interest for the selection of beverages, this study aimed to evaluate the contents of nutrients and health ${\cdot}$ functional elements in the beverages. Total 161 beverages that bear nutrition lable (NL) as nutrition table and health ${\cdot}$ functional elements information were collected and classified to 8 groups. The evaluated nutrients that are obligatory for NL in Korea were total calorie, carbohydrate, protein, fat, and sodium. Presented values showed that milk & yogurt and soy milk are the most wholesome beverages while the total caloric contents also were higher among 8 groups. Sodium contents in soy milk were higher than any other groups. The caloric contents of other beverage groups come mainly from carbohydrate presumably simple sugar. The caloric content of sports drinks is the lowest but the sodium content is variable among products showing the range of 0 - 100 mg/100 ml. Nonobligatory nutrients for NL frequently expressed are Ca, Fe, vitamin C, folate, and dietary fiber. Their content per serving size does not exceed the tolerable upper intake level, however, habitual multiple intakes of certain product require attention for the prevention of overintakes. Many health ${\cdot}$ functional elements as catechin, carnitine, polyphenol, and nucleic acids etc were listed in NL without presenting the content and their functions appear to be exaggerated compared to the known scientific evidence.

The present study was carried out to evaluate the physiological effects of seaweed supplementation on blood glucose levels, lipid profile, and antioxidant enzyme activities in subjects with type 2 diabetes mellitus. Subjects were randomized into either a control group or a seaweed supplementation group. Pills with equal parts of dry powdered sea tangle and sea mustard were provided to the seaweed supplementation group three times a day for 4 weeks. Total daily consumption of seaweed was 48 g. We found that total dietary fiber intake was 2.5 times higher in subjects receiving seaweed supplementation than in the control group. Accordingly, fasting blood glucose levels (p<0.01) and 2-hour postprandial blood glucose measurements (p<0.05) were decreased significantly in those ingesting seaweed. Furthermore, the serum concentrations of triglycerides were decreased and high-density lipoprotein cholesterol was increased significantly in seaweed supplement group (p<0.05). However, the concentrations of total cholesterol and low-density lipoprotein cholesterol were not affected by seaweed supplementation. The level of thiobarbituric acid reactive substances in erythrocytes was significantly lower with seaweed supplementation compared to controls (p<0.05). Catalase and glutathione peroxidase activities with seaweed supplementation were higher than the controls (p<0.05), but superoxide dismutase activity was not affected. We, therefore, conclude that ingestion of seaweed influences glycemic control, lowers blood lipids, and increases antioxidant enzyme activities.

The implications of incorporating deoiled rice bran (DORB) in diet on the utilization of certain nutrients had been examined through balance studies made with 6- and 10- week-old Japanese quails. The stuffs evaluated in this study had their origin from two different types of processes- a batch extraction (DORB-B) and another continuous process (DORB-C), and each included at 10, 20 or 30% level in an iso-nitrogenous and iso-caloric diet. On chemical analyses, the DORB-B was found to contain crude protein, 19.0; ether extract, 0.79; total ash, 17.05; Ca, 0.11; P, 1.92; glucose, 2.35 and starch 11.22 g/100 g day matter. Corresponding values for DORB-C were 15.02, 1.56, 13.0, 0.40, 2.76, 2.16 and 19.0, respectively. The data on nutrient balances with quails fed diets containing the two-types of DORB suggested no significant (p>0.05) differences in per cent retention of diet dry matter (DM), organic matter (OM), ether extract (EE), gross energy (GE), nitrogen (N), crude fiber (CF), calcium (Ca) or phosphorus (P) content attributable to the extraction process. The age of the birds also appeared to have no significant (p>0.05) effect on nutrient utilization by them. However, the level of inclusion of DORB had a significant (p<0.05) effect on nutrient utilization by quails in that the retention of dietary N, EE, CF, Ca and P was better at lower than at higher levels. It is concluded that the DORB, irrespective of extraction process, can safely be employed upto 20% level in diet of adult Japanese quails without noticeable interference in utilizing the major dietary nutrients.

Supplying an appropriate amount of feed is an economical and environmentally friendly by increasing the nutrient digestibility of livestock and reducing nutrients released from overfeeding. Therefore, this study was conducted to determine the nutrient digestibility according to dietary feeding levels of Hanwoo steers. Three treatments in feeding trial were used feeding amount based on the maintenance energy level of the Korean feeding standard for Hanwoo (2022): 100% (control, CON), 140% (treatment 1, TRT1), and 190% (treatment 2, TRT2). The experiment was designed in replicate 3×3 balanced Latin square designs using six Hanwoo steers. In this study, energy value was predicted according to treatment groups. In addition, nutrient digestibility and energy value were measured through a feeding trial to Hanwoo steers. All energy values, including total digestible nutrients and digestible energy, were predicted to decrease linearly with increasing feeding levels. TRT2 showed lower digestibility than CON for dry matter, crude protein, non-fiber carbohydrates, and total digestible nutrients in the feeding trial (p<0.05). However, there was no significant difference between CON and TRT1. Total digestible nutrients (TDN) and digestibility of feed are set based on the maintenance energy. However nutrient digestibility and TDN decreased when feeding level increased by more than 190% compared to maintenance energy in this study. Therefore, it is necessary to correct the TDN by considering the feeding level when mixing the feed.
