The aspects and satisfaction on university foodservice were investigated to provide basic information for better foodservice in university by questionnaires. The survey was conducted in Daejon, and data were analyzed by SAS. Although 87.3% of subjects were under foodservice, only 2.0% of them preferred the foods served in university. The most favorite reason for foodservice was indicated as no need on lunch bag(31.1%) and frendship of classmates(25.5%). The most unfavorite reason for foodservice was indicated as bad taste of foods(68.7%) or many dislike foods(13.2%), also dirty eating place(7.7%). The subject liked ssalbap, baechu kimchi, beef foods. The acceptance about kongbap, yulmu kirnchi, beef products was higher in men than women(p<0.05). The preference of mieokkuk was higher in women and that of beef soup was higher in men(p<0.05). The degree of satisfaction was lower in men than in women about the amount of foods(p<0.001). Also the degree of satisfaction was lower in women than in men about sanitary condition of eating place. 54.6% of them had taken the unwanted materials in foods and 3% of them experienced the deteriorated food. The results suggest that food preference of subjects should be considered in meal planning and various cooking method should be utilized to enhance taste of foods for better foodservice. Also, the importance of various foods intake must be periodically and continuously taught to them through nutrition education.

This study was carried out to investigate the effects of Korean safflower seed powder supplementation on calcium and bone metabolism in growing rats. Male sprague-Dawley rats of 50±2g of weight, were divided into four groups after arrival : the control group(CD group), and safflower seed powder groups(LSD, MSD, HSD groups). These groups were fed by each diets contained 6%, 10%, 14T% safflower seed powder, respectively. They were fed each experimental diets for 4 weeks, respectively. The results were summarized as follow : Food intake was not different among the groups. Body weight gain was higher weight in MSD and HSD groups than in control group or LSD group. The weight spleen was not significantly difference among the groups. But the weight of liver, kindey and epididymal fat had higher in safflower seed powder groups(LSD, MSD, HSD) than in control group(CD group). Serum alkaline phosphatase activity was higher in CD group than in safflower seed powder groups. Feces and urinary calcium excretion decreased as the amount of contained safflower powder. Bone calcium was higher in safflower seed powder groups than in CD group. Serum calcium was significantly lower in CD group than in safflower seed powder groups. The results of this study suggest that safflower seed powder affect in calcium and bone metabolism in growing rats fed normal Ca by in creasing Ca retention.

Body fat proportion is a major issue in health. Age-dependent change in body fat often observed in normal population. A series of indirect estimates of body fat have been developed. There are hydrodensitometry, BIA and anthropometry equation for the estimation of body fat. Hydrodensitometry has been regarded as a common criterion method. Usually. BIA made it possible to analyze body fat mass more related to hydrodensitometry than anthropometry. The purpose of this investigation were to compare body fat proportion and body composition between male and female college students and to know which anthropometry equation for the estimation of body fat proportion was most closely associated with the result from BIA. The subjects were twenty-one healthy male(21.5±2.5 yr.) and twenty female college students(22.1±1.4 yr.). They underwent BIA to determine body fat proportion and Body composition. Anthropometric measurements were taken of height, weight, skinfold thicknesses for 9 parts and circumferences for 12 parts of body. The results obtained are summarized as follow : Weight was 71.6±16.2 kg in male and 56.3±7.6 kg in female respectively. BMI was 23.1±4.7 in male and 21.6±2.2 in female. Relative body fat determined by BIA was 17.2±7.0% in male and 29.3±4.2% in female. Circumference and skinfold that had the highest correlation with body fat by BIA were waist in male and female(r=0.94, r=0.76 respectively), and suprailiac in male and subscapular in female(r=0.91, r=0.63 respectively) According to correlation coefficient, estimation of body fat by Wilmore equation seemed to be more closely associated with body fat determined by BIA in both sex. Also correlation analyses showed that estimation of body fat by anthropometric equation seemed to be more closely associated with determined by BIA than BMI in male(r=0.98).

The goal of this review is to know the current epidemiologic, metabolic, and clinical data to support limiting dietary fat intake as a preventive strategy for certain chronic disease, and suggest desirable dietary fat consumption for Korean. Over the past 10 years, public health policy for Korean has placed an emphasis on problems of overconsumption and nutrient imbalance, with an emphasis on dietary fat. An association between dietary fat, excessive energy consumption, and obesity has been noted in some studies. Excessive consumption of fat - especially saturated fat- has been related with the increase of cardiovascular disease. Excessive intake of fat has. also been associated with certain types of cancer, although the interpretation of the data is limited by the difficulty in distinguishing high-fat from high-energy diets. The efficiency of dietary fat restriction as a preventive strategy for these chronic disease tends to evoke controversy, because the role of dietary fat in the etiology of these disease is of both a qualitative and quantitative nature. At present, Korean dietary recommendations are that total fat intake be 20% and saturated fat intake be 6% of total energy for healthy adults. The percentage of fat relates to tat intake relative to total dietary energy obtained from all the macronutrients. Excess energy intake can be a consequence of excess dietary fat and lack of total energy consumption. Major change in lifestyle habits in a population can have a variety of consequence, many of them unforeseen. Therefore, recommendation for a change in lifestyle habits particular dietary habits must have a definite scientific foundation.

Newly developed albendazole (Zentel®) is a broad spectrum anthelmintic with high activity against intestinal nematodes as well as trematodes and cestodes infections. The present study was undertaken to observe the morphological changes of Hymenolepis nana which obtained from experimentally infected mice after treatment with albendazole. For this study 20 mice were artificially infected with eggs and 16 of them were given albendazole (1×100mg/kg) four weeks after infection. The worms were collected from the small intestine of the mice which were autopsied at 1 and 2 hours after treatment. The fine structure of the collected worms were studied by means of scanning and transmission electron microscopies. The findings were compared with those of untreated worms. The results are as follows: 1. The worms obtained from non-treated mice showed that the whole surface is covered with many microtriches. Microtriches of H. nana may be divided into three anatomical regions; a base, junctional region and cap. Tegumental layer showed well developed syncytium which included a lot of number of discoidal secretory bodies. 2. Many blebs were formed on the surface of the damaged tegument of the worm at 1 hour after treatment with albendazole. The bleb was packed by plasma membrance and included matrix which uniform electron density. Some bleb surface has microtriches. 3. The destruction of tegumental syncytium was recognized at 2 hours after treatment with albendazole. Therefore the blebs on the worm sufrace caused to the death by the tegumatal bursing.

In these experiments the effects of fatty acids, linoleic acid(LA), arachidonic acid(AA), conjugated dienoic linoleic acid(CLA) and stearic acid(SA) on the cell proliferation of IEC-6 cell and the rate ³H-thymidine incorporation in IEC-6 cells has been determined. At 10uM concentration LA and AA were more stimulated IEC-6 cells growth then BSA. LA and AA were growth stimulatory. CLA and Saturated fatty acid, SA did not show any stimulatory effect on cell growth, they were growth inhibitory. ³H-thymidine uptake showed the same results. LA and AA were more increased ³H-thymidine uptake then BSA. The stimulatory effect of LA or AA were even more profound in the presence of IGF. Both the cell number analysis and ³H-thymidine incorporation revealed that 10uM LA or AA were stimulatory on IEC-6 cells growth, but CLA and Saturated fatty acid, SA were inhibitory on IEC-6 cells growth.
