To study physiological and ecological characters of the secondary mycelia of Armillariella mellea, it was cultivated on the various media. It was grown very well on the malt extract medium compared with its growth on yeast extract medium, potato dextrose medium and Hamada medium. The temperature of 27℃ gave the best condition for it to grow. The highest rate of growth was shown in medium of pH 6. Heteroauxin of 5 ppm concentration showed a increase as 26.2% in growth in compared with the control group. Gibberelline 10ppm, Tomatoton of 10,000 dilution and Adoton of 5,000 dilution showed positive effect. It was shown that the use of above hormones in appropriate concentration brought the effect of growth, but overuse of them brought inhibitory effect. Under the same condition of 200ppm concentration, vitamin A gave the highest growth of 18.2% than that of the control used.

유당의 첨가가 성장기 암컷 흰쥐에서 골함량과 골밀도에 미치는 영향

The effects of dietary lactose supplementation on bone mineral density and bone mineral content in growing rats are uncharacterized. We studied growing female rats fed a diet either control of supplemented with lactose for 9 weeks. The animal was scanned to determine the BMD and BMC using dual energy X-ray absorptiometry (FIXImus, GE Lunar Corporation, Madison, WI). Food intake and FER were not affected by loctose supplementation. But the lactose group had significantly higher spine bone mineral density(0.1517±0.0034(g/㎠) vs 0.1626±0.0095(g/㎠)) and spine bone mineral density/weight than the control group. And femur bone mineral density/weight as well as femur bone mineral content/weight were higher in the lactose supplemented group. These data suggest that lactose supplementation may be a useful way in growing children in which there is a desire to increase bone mineral density.

The purpose of this study was to investigate the perception of desirable body shape and the concerns of body weight in 200 college students(106 males, 99 females: average age-21yr). Daily food intake was estimated by 24-hr recall and analyzed by computer-aided nutrient analysis(CAN) for nutrient intake. Body weight and height were measured and BMI was calculated. The percentage of students actively practicing concerned weight control was 81.1% for male and 95.1% for female. Of those male students actively practicing weight control, the majority of student chose reducing meal size as the preferred method. Among females chose exercise and dietary restriction as the preferred method. However, few students chose fasting as method of weight control. there was a sex difference in self-evaluation of their body weight. Male students underestimate their body weight but female students overestimate their body weight compared with their calculated actual body weight(RBW or real body weight). Only 40% of male students and 21% of female students recognized that their energy intake is below RDA. However, data from a 24-hr dietary recall revealed that the actual percentage of students consuming less energy than the recommended RDA was 59% for male students and 69.8% for female students. The percentage of fasting from one meal per day or eating irregularly was 39% male students, and 51% of female students. Finally, students assessed as being over weight and obese were 27% for male students and 57.7% of female students actually recognized they were obese themselves. In conclusion, among college students, there is a great need to provide nutrition education concerning appropriate body weight and dietary intake for healthy lifestyles.

The purpose of this study was to examine the effects of isoflavones supplementation on bone mineral density and bone mineral content in growing female Sprague-Dawley rats. Twenty-seven rats were divided into three groups casein diet, casein+1/2IF(1.7 mg isoflavones/g protein)diet, and casein+IF(3.4mg isoflavones/g protein) diet. All rats has been fed on experimental diet and deionized water ad libitum for 9 weeks. Bone mineral density(BMD) and bone mineral content(BMC) were measured using PIXImus(GE Lunar Co, Wisconsin, USA.) in spine and femur on 9 weeks after feeding. Diet did not affect weight gain and mean food intake. Food efficiency ratio was lower in casein +IF groups. The casein+IF and casein+1/2IF group had significantly higher spine and femur bone mineral density than the casein group. We found that bone mineral density effected by isoflavones supplementation has been resulted differently in accordance with the type of bone. Therefore, isoflavones supplementation may be beneficial on spine and femur BMD increasement in growing female rats.

The purpose of this study was to investigate the food preference and food behavior of college students of Taegu, Korea. This survey was carried out through questionaries, and the subjects were 110ma1e and 105 female students. The 66.5% of male and 87% of female students were concerned about changing their food habit. The score of nutritional knowledge of males was significantly lower than the score of females. Both male and female students considered that supper was the most important meal of the day and skipped breakfast frequently Results of this study showed that three most important factors in food selection were taste, price, and preference. Beef and pork were preferred by males and beef and chicken were preferred by females as meat and poultry sources. Mackerel and hair tail were most often preferred by both males and females as fish sources. Chinese cabbage and cucumber were most often preferred by both males and females as vegetables. Citrus fruit and apples were preferred as fruit. Frozen potatoes and ham.saugage, carbonated brinks and fruit juice were most often preferred by both males and females as processed food and drink. There was a significant correlation between nutrition knowledge score and dietary behavior score in college students. The levels of energy, carbohydrate, calcium, iron, and vitamin A intake were significantly correlated with dietary behavior score in female students. There was a significant negative correlation between alcohol and dietary behavior score in male students. Key words: food preference, food behavior, college students
