In order to investigate the effect of the combined dietary animal and vegetable proteins on growing female and male rats and mice. 25 female and 25 male rats of 4 weeks old weighing approximately 43-65g and 47-60g, respectively, were subjected to feeding trials for 4 weeks and then subsequently to metabolic trials for 10 days. In case of mice, 25 female and 25 male mice of 4 weeks old weighing approximately 12-17g and 12-16g, respectively, were equally treated. The dietary energy level was set as 3600 kcal ME/kg, and protein and fat provided respectively 12 and 5% of the dietary energy. The rest 83% of the energy level was supplied with appropriate amounts of starch and glucose. The following results were obtained. The body weight gain of female and male rats were increased as the combined dietary animal protein level increased. Whereas that of male mice was the highest for the diet E(Ap 10+Vp 90). Food efficiencies both of female and male rats were improved as combined dietary of animal protein increased. Male rats were superior to that of female. In the mice, the food efficiency value of male mice was superior to that of female. And the values of the male showed the same fashion as that in the growth rate, although it was not for the female. Protein efficiencies, both of female and male rats, were improved as combined dietary of animal protein level increased. That of male mice was in accord with the body weight gain and food efficiencies. But that of female mice was not accordant. Nitrogen retention of the experimental diets in the same protein level was in proportion to nitrogen intake. That of male mice was improved as animal protein level increased, but, that of female mice was not. Body protein utilizability was found to be superior in mice to rats. Blood serum protein level was not found to be affected by the experimental diets in the same protein level. The best combination ratio of animal and vegetable protein seems to be variable depending on the sex and species of animals, and the best diets for female and male rats and female and male mice were found to be experimental diet A(Ap 10+Vp 90) or diet B(Ap 75+Vp 25), diet C(Ap 50+Vp 50), and diet E(Ap 10+Vp 90), respectively. From the above-mentioned results that there was no difference in growth rate of body weight gain from the weanling period to puberty, and that the protein requirements of rats and mice were different from each other.

This article concerned with the nutritional status and the taste of the lunch box of 311 middle school girls in Kwangju City from May 18 to June 12 in 1987. The purpose of this research was making materials to show direction of the education about nutrition by checking relationships among the nutritional status for the lunch box, the taste of food and the environmental factors. The results observed in the study were as follows: 1. The intake of nutrition from the lunch box and the ratio between the recommended dietary allowance and the contained nutrients in the lunch box as follows. Calorie(603 Kcal, 78.6%), protein (21.7g, 93.1%) Animal protein (10.3g, 132.1%) calcium (151.7 g, 56.9%) Ferrum 93.1 mg, 51.7%), Vitamin a (129.3 RE, 55.4%) Vitamin B1 (0.29 mg, 72.5%), Vitamin B (0.26 mg, 55.3%) Niacin (4.7 mg, 94.0%), Vitamin C 913.2 mg, 79.0%). Except animal protein, all the recommended dietary allowance. 2. According to the intake of calorie, the ratio of taken carbohydrate, protein and fat was 77.7 : 15.5 : 6.8. The intake of protein was desirable but most of calorie depended on carbohydrate. Among the total intake of protein, the ratio of animal protein was 47.5%, which was a high rate. 3. Most of calorie (75%), was taken from staples, protein (41.5%), vitamin B1 (48.3%) were taken at the same rate from staples and side dishes. Most of fat, calcium, ferrum, vitamin A, vitamin B, and vitamin C, was taken from side dishes. 4. In taking among the five basic food groups, proportion of the grain fourth food group was the highest, light color vegetable the third food groups, proportion of the grain fourth food group was the highest, light color vegetable the third food group was second, and Calcium food the second food group was the lowest. 5. As the staples, students liked tchajangmyon, mandu and ttokkuk as written order. They disliked Kongbap and Patpap. As the side dishes for the lunch box, they liked kimchi, ham, sausage, cuttlefish, dried slices of filefish, eggs and green seaweed as written order. As a side dishes they liked Laver, Cucumber, Squid, lettuce, Potatoes. They disliked pork fat, cow's intestines, cow's liver, Crussian carp, pickled fish. The favorite snack was fruits, ice cream, hamburger, Chocolate and milk. 6. In taking condition of the principal food, rice rate (65.6%) was the most, and mixed food was 5 or 10%. 7. Favorite cooking was frying, roasting and kimch. But disagreeable cooking was pickling. 8. Favorite food was what was pungent but disagreeable food was what was salty. 9. the higher parents educational background was, the higher their income was. Also the more various the information about the nutrition was, the better the intake of nutrition was. 10. The preference tendency influenced in choosing the side dish of the Lunch box. The higher the preference tendency of the girl students became, the better their nutrition condition became.

Fresh sea squirt meat requires a modified processing and preservation process because it has a short shelf life due to its high moisture content and strong proteolytic enzyme activity. In this study, bottled sea squirt meat prepared in vegetable oil (BSMO) to enhance the consumer acceptability was exposed to ${\gamma}$-ray (Co60, 10 kGy/h) irradiation to extend the shelf life without the use of a heating process. Response surface methodology was used to determine the optimal mixing ratio of BSMO containing 5% dehydrated fresh meat. Texture analysis and nutritional evaluation were also performed on a control and BSMO samples. The volatile basic nitrogen (VBN) content and total cell count were measured to determine the shelf life of irradiated BSMO products during chilled storage at $4^{\circ}C$ for 60 days. According to a panel of 10 trained tasters (aged 20-29 years), the optimal mixing formulation was 80 g meat in 60 mL of mixed vegetable oil (30 mL of olive oil and 30 mL of sesame oil). The highest rated formulation, according to a panel of nine trained tasters (aged ${\geq}30$ years), was 80 g meat in 60 mL of mixed vegetable oil (42 mL of olive oil and 18 mL of sesame oil). Moisture, ash, and protein contents in BSMO did not change significantly (P < 0.05) compared with the control. A higher lipid content ($0.84{\pm}0.23$ to $2.13{\pm}0.61$; P < 0.05) was observed due to the presence of vegetable oil on the surface of BSMO. The vegetable oil raised the hardness, springiness, cohesiveness, gumminess, chewiness, and resilience of BSMO. BSMO products remained edible after 50 days of storage at $4^{\circ}C$ based on the VBN content (BSMO 1: $27.92{\pm}0.96$ mg/100 g, BSMO 2: $24.84{\pm}1.95$ mg/100 g) and total cell count (BSMO 1: $4.60{\pm}0.80$ log CFU/mL, BSMO 2: $3.65{\pm}0.20$ log CFU/mL) when compared with standard levels of VBN (25.00 mg/100 g) and total cell count (5 log CFU/mL), respectively. The results showed that irradiated BSMO products could help to expand the processed seafood market and increase the popularity of seafood among the younger generations.

The effect of dietary casein, calcium, magnesium and some vegetable oils such as seasme, perilla and soybean oil on the serum cholesterol level in the rabbit were studied for a period of 5 weeks using isocalories and isonitrogenous as basal diets. The experimental rabbits fed the following basal diets containing crude protein 68.47%, carbohydrates 13.35%. fats 16.18% and vegetable oil 10%. casein 10%, calcium and magnesium according to experimental plan making. In order to calculate the feeding efficiency, protein efficiency and calorie efficiency during period, the body weight gains were measured at the same time using same balance, respectively. The results are summarized as follows. Body weight gains per week of the group fed perilla oil, calcium and basal diet were the higher than any other groups. And body weights gains per week of the group fed basal diet, vegetable oil were the lower than any other groups. In the case of efficiency of reed, protein and calorie, the efficiency ratios of the group fed perilla oil were the higher than any other groups. Especially, perilla oil and calcium diet effect on body weight gain in rabbit. In the case of serum protein, the total proteins in serum were almost same value for all the groups. Serum albumin of group fed basal diet. vegetable oil and casein were the higher than any other groups. The ${\alpha}$-globulin of the groups, fed basal diet and calcium was the lower than any other grosps. The ${\beta}$-globulins of the groups fed basad diet, perilla oil and casein were the highest value. In serum lipoprotein, lipalbumin was almost same value for the groups fed vegetable oil, but fed vegetable oil and calcium diet was the lowest value. The ${\beta}$-lipoprotein in high cholesterol level group was increased some degree, the group fed perilla oil added was lower. The ratio of ${\beta}$-lipoprotein per lipalbumin was from 0.11 to 0.26. The ratio of lipalbumin per total lipoprotein was high in calcium and soybean oil added diet. In serum triglyceride, the level of triglyceride of groups fed seasme oil or perilla oil was the higher than any othe groups, but in the group fed casein and calcium or magnesium, the level of triglyceride level was decreased. Calcium and magnesium effect on triglyceridge level lowering action. In serum total cholesterol, the group does fed vegetable oil with basal diet and casein added more, total cholesterol level increased as much as triglyceride level increased. But the group does fed perilla oil and magnesium shows total cholesterol level decreased remarkably. In the group fed basal diet with calium, the amount of serum calcium was increased, but of serum magnesium was decreased. In the case of blood glucose, the group fed basal diet and vegetable oil was decreased. According to the regression and correlation coefficient in blood components in rabbit, there are positive correlation $${\gamma}{\sim_=}1$$ between serum cholesterol and triglyceride, ${\beta}$-lipoprotein, ${\alpha}$-globulin, calcium and magnesium according to diet composition. From the above results, the serum cholesterol level lowering factors in rabbit, was the amount of triglyceride and ${\beta}$-lipoprotein which was decreased in perilla oil fed. It assumes that serum cholesterol and triglyceride level lowering factors are not only unsaturation degree of fatty acid but the amount of calcium and magnesium and the ratio calcium per magnesium 2:1 in the diet.

Nutrition is one of the factors influencing cognitive functions. But, the role of nutrition on cognitive functions within the elderly is recognized to a lesser degree. The aim of this academic endeavor was to analyze the affiliation between nutritional status and cognitive functions of the elderly in Korea. 316 subjects, of 114 male and 201 female aged above 65 years, were gathered from university hospital clinics, Elderly Welfare Centers, and Health Welfare Centers located in the district of Seoul, Gyeonggi province, and Incheon in Korea. The cognitive function was tested by the Korean-Mini Mental State Examination (K-MMSE) questionnaire. Nutrition intake was assessed by a 24-hour recall, a food frequency questionnaire (FFQ). Nutrition adequacy and quality were assessed by the Nutrition Screening Initiative (NSI) checklist, the nutritional adequacy ratio (NAR), and the mean adequacy ratio (MAR). The elderly with normal cognitive function status displayed significantly higher levels of calcium, riboflavin, thiamin, folate, vitamin C, vitamin E, vitamin B6, phosphorous, potassium, iron, niacin, zinc, animal fat, animal protein, polyunsaturated fatty acids, total protein, vegetable oil, vegetable protein, fiber than levels of the elderly with moderate cognitive impairment. The K-MMSE score positively correlated with of high consumption of pork, white radish, sea mustard, tomato, tangerine, grape, apple, and ice cream, and K-MMSE was negatively associated with high intake of potato, anchovy, fish cake, and mushroom. The findings suggest that nutritional status is affiliated with cognitive function within the elderly of Korea. The consumption of variety of foods and nutrients ensures adequate cognitive function in the Korean elderly.

The purpose of this study was to find out the dietary attitudes and behaviors, intake frequencies of food groups, health-related opinions and practices, and sociodemographic characteristics of housewives in Wonju-Gun rural area. Interviewers asked 413 housewives about obove informations and then recorded. The results were as followes : Using the factor analysis processing, 17 questions about dietary attitudes and behaviors were categorized into 5 groups such as fidelity of diet, the healthful dietary attitudes, the eating practices concerning about items and amount, eating speed and the extent of coincidence in food preference within a family. The role of the housewives was a major factor affecting the dietary attitudes and behaviors. Those who work as housewives and farmers concurrently had good dietary practices concerning about items and amount, but they were interested about health-directed dietary attitudes at a significantly lower level. Food frequencies of 9 groups, animal protein food, fruits and vegetables, milk and milk products, small fishes such as anchovy, soybean curd and beans, seaweeds, vegetable oil, frying food, soybean paste were significantly associated with subjects' age, role, and education and income level. Whether or not intake of soybean paste was considered. protein food intake was altered, and the difference between two situations increased much more as age was higher. We noticed that intake of soybean paste improved the status of protein nutrition. Our subjects ate calcium sources and dishes using vegetable oil insufficiently. Those who had much interests for good health, revealed to be an active practitioner in the aspects of healthful dietary attitudes, but fidelity of diet, eating practices concerning about items and amount showed significant association with balanced life style.

Epidermal cell adhesion molecule (EpCAM) is a tumor-associated antigen (TAA), which has been considered as a cancer vaccine candidate. The EpCAM protein fused to the fragment crystallizable region of immunoglobulin G (IgG) tagged with KDEL endoplasmic reticulum (ER) retention signal (EpCAM-FcK) has been successfully expressed in transgenic tobacco (Nicotiana tabacum cv. Xanthi) and purified from the plant leaf. In this study, we investigated the ability of the plant-derived EpCAM-FcK (EpCAM-FcK^P) to elicit an immune response in vivo. The animal group injected with the EpCAM-FcK^P showed a higher differentiated germinal center (GC) B cell population (~9%) compared with the animal group injected with the recombinant rhEpCAM-Fc chimera (EpCAM-Fc^M). The animal group injected with EpCAM-FcK^P (~42%) had more differentiated T follicular helper cells (Tfh) than the animal group injected with EpCAM-Fc^M (~7%). This study demonstrated that the plant-derived EpCAM-FcK fusion antigenic protein induced a humoral immune response in mice.

This study was conducted to investigate the relationship between lactational capacity and intakes of energy and energy-yielding nutrients. Food consumption, intakes of carbohydrate, protein, fat and energy and quantity and proximate composition of milk of 11 lactating Korean mothers were determined at 1, 2 and 3 months postpartum longitudinally. Food consumption was estimated using a 24-hour recall method ; intakes of energy and energy-yielding nutrients were calculated according to the Food Composition Table. Daily milk production was estimated using a 72-hour test-weighing method ; protein, fat, lactose and energy concentrations were analyzed. Average intakes of energy and protein were 1974$\pm$386㎉/day and 67.0$\pm$12.3㎉/day, these were 73% and 74% of the Korean Recommended Allowances, respectively. Average milk yield was 720.1$\pm$123.3ml/day containing energy 59.6$\pm$9.5㎉/dl, protein 1.1$\pm$0.1g/dl, fat 2.7$\pm$0.8g/dl, and lactose 6.3$\pm$0.3g/dl. No relationship existed between the intakes of carbohydrate, protein, fat and energy and the quantity and proximate composition of the milk. However, the intakes of energy, carbohydrate and vegetable protein were inversely related to the concentrations of energy and lactose in the milk. This result indicates that lactational capacity may be affected by the other factors excluding intakes of energy and energy-yielding nutrients and a high intake of energy may not guarantee optimal lactational capacity.
