This study was carried out to determine the depression symptoms and nutritional status of elderly females that ate congregate meals at lunch in rural Pocheon. The subjects were 18 elderly females aged over 65 (75.7±4.6 years) and information on smoking, subjective health status, depression symptoms and malnutrition risk were collected using a questionnaire administered with the help of trained research assistants. Measurements included mid-arm circumference and calf circumference. Food consumption for 3 days during breakfast and supper were determined by 24-hour recall and food consumption at lunch was determined as the difference between the amounts served and the plate waste. All data were compared between two age groups (≤ 75 and > 75). The subjects had the lowest nutrient adequacy ratio (NAR) for vitamin B6 (0.523), followed by calcium and niacin and the lowest index of nutrient quality (INQ) for calcium (0.738). The older elderly had significantly lower NAR for vitamin B1, vitamin B2, vitamin B6 and niacin as well as significantly lower mean adequacy ratio (MAR) compared to the young elderly. They also had significantly lower INQ for vitamin B1 and vitamin C and significantly thinner arm circumference (28.3 cm vs. 31.3 cm). They consumed more than 40% of their daily intake for each nutrient at lunch. Higher proportions of nutrient intake from lunch provided evidence of the importance of congregate meals, suggesting that the government and society should support congregate meals to improve nutritional status.

The purpose of this study was to assess the consumption patterns of Makoli and to provide age-specific suggestions to increase the popularity of newly developed products. The subjects of the study were 373 men and 329 women, and information was obtained by self-administered questionnaire in December of 2010. One major finding of the study was that regardless of gender, consumption of Makoli was correlated to age: older respondents drank more Makoli. Those in their thirties and older, especially women, drank Makoli at home with family. The reasons given for liking or disliking Makoli differed among age groups, but were the same between genders. More subjects in their twenties liked Makoli because of its distinctive taste, while more in their forties liked it for its cultural value. Subjects in their thirties disliked it because it caused headaches, while more in their forties complained of burping. Both genders in their twenties suggested that TV and internet advertisements may be the best strategy to increase the popularity of newly developed Makoli products, and women in their forties suggested promoting Makoli’s health benefits. The low calorie content of new Makoli products appealed to women of all age groups and men in their twenties and thirties. Women in their forties were also attracted by Makoli’s possible effect to alleviate constipation.

Aloe vera 껍질에서 항우식 및 항염증제재를 개발하기 위해 항우식 및 항염증 활성이 있는 물질을 분리, 정제하였고, 활성이 우수한 ethylacetate층을 silica gel column chromatography 및 preparative thin layer chromatography를 통해 두 가지 활성물질을 정제하였다. 정제된 두 가지 물질은 UV spectrum과 FT-IR, ^1H-NMR 및 Mass spectrum 분석을 통해 aloe-emodin과 barbaloin으로 동정하였다.

토끼에서는 수정란 이식과 같은 기본적인 번식공학적 방법의 효율성이 아직 생쥐와 같은 실험동물에 비해 떨어지고 있어 생물공학적인 기술을 응용하는데 큰 어려움이 있다. 특히 유전자 이식에 의한 형질전환 토끼의 생산과 같은 생물공학적인 기술을 실용화하는데 효율이 높은 수정란이식 기술의 개발이 필수적이라고 할 수 있다. 본 연구에서는 토끼에서 수정란 이식 기술의 첫 단계인 과배란 유도를 효율적으로 이용할 수 있는 방법을 정립하기 위해 반복적인 과배란 유도가 배

Sprague-Dawley 흰쥐에 고지방식이로 6주간 식이하면서 천궁 열추출액을 경구투여하여 혈장 중 GOT, GPT 및 LDH 활성과 지방의 분해와 합성에 관여하는 코티졸과 인슐린의 함량을 측정하였다. 또한 지방침착억제효과를 광학현미경으로 관찰하였다. GOT, GPT 및 LDH의 활성은 정상군보다 높았으나 대조군보다 낮았으며 현미경 관찰을 통하여 지방간이 약간 개선되고 있음을 나타내어 천궁의 투여가 고지방식이에 의한 비만유발의 개선효과의 경향을 나타내었다.

This study was divised to observe the inhibitory effect of growth rate of human colon cancer cells by Eucommial leaf extract, in vitro. Three species of human colon cancer cells, HRT-18, HCT-48 and HT-29, were used for the experiment. Each extract of Ecommial leaf was prepared by extraction with water, 95% alcohol, acetone, chloroform and petroleum ether, and then the inhibitory effect of each extract on the growth rate of cells was compared with control group and each other. The expermental results obtained are summarized as follows ; 1. Inhibitory effects on growth rate of human colon cancer cells were strongest in the petroleum ether extract and next in the chloroform extract. 2. Inhibitory effects on the growth rate of the cancer cells by extracts of water, 95% alcohol and acetone were weaker than that of petroleum ether and chloroform. 3. Inhibitory effect of each extract on the cancer cell growth was shown most strong activity in HT-29, and was in order of HRT-18 and HCT-48. In view of the results, it could be suggested that inhibitory effects of non-polar solvent`s extracts against the cancer cell growth were more stronger than that of polar solvents and the effects were indicated defference according to the species of the cells.
