To elucidate the effect of a 4 week dietary supplementation with pumpkin water extract on serum lipid and fasting glucose levels, 41 female collegians residing in the Gyeonggi area were recruited. The subjects were divided into three groups: placebo-control (PC, n=11), treatment A (TA, 100 ml/day, n=13), and treatment B (TB, 300 ml/day, n=17). Total serum cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglyceride (TG), and fasting glucose were analyzed. The average age, height, weight, and body mass index of the subjects were 21.3 years, 161.1 cm, 53.0 kg, and 20.4 $kg/m^2$, respectively. The average total cholesterol, HDL-cholesterol, LDL-cholesterol, TG, and fasting glucose level (mg/dl) were 171.4${\pm}$26.1, 63.5${\pm}$11.4, 92.6${\pm}$22.9, 76.8${\pm}$32.0, and 89.1${\pm}$8.2, respectively. There were no significant differences among the three groups in any measured parameters, and between the pre- and post-study values of the all parameters. The results indicated that the 4 week pumpkin water extract supplementation (100 ml, 300 ml) did not influence the serum total cholesterol, HDL-cholesterol, LDL-cholesterol, TG and fasting glucose level in female collegians.

This study was performed to investigate the antimicrobial effect of the Viscum album var. coloratum extracts against food-borne pathogens. First, the Viscum album var. coloratum was extracted with methanol at room temperature and the fractionation of the methanol extracts was carried out by using petroleum ether, chloroform, and ethyl acetate, and methanol, respectively. The antimicrobial activity of the Viscum album var. coloratum extracts was determined by using a paper disc method against food-borne pathogens and food spoilage bacteria. The petroleum ether extracts of Viscum album var. coloratum showed the highest antimicrobial activity against Bacillus cereus and Shigella dysenteriae. Synergistic effect in inhibition was observed when Viscum album var. coloratum extract was mixed with Perillae folium extract as compared with each extract alone. Finally, the growth inhibition curves were determined by using petroleum ether extracts of Viscum album var. coloratum against Bacillus cereus and Shigella dysenteriae. The petroleum ether extract of Viscum album var. coloratum had strong antimicrobial activity against Bacillus cereus at the concentration of 5,000 ppm. At this concentration, the growth of Bacillus cereus was retarded more than 24 hours and up to 12 hours for Shigella dysenteriae. In conclusion, the petroleum ether extracts of Viscum album var. coloratum inhibit efficiently Bacillus cereus and Shigella dysenteriae.

Homelessness became a major social problem in Korea. And the homeless presents many kinds of problems in social functioning. In studies on the homeless, Physical and mental health, alcohol and subtance abuse, the vulnerability of the social support have been frequently described as major characteristics of the homeless. Of the homeless' psychosocial characteristics, this article focused on the lack of the social support, which plays a important role on the exit from homelessness. The lack of social support has been mentioned as cause for homelessness. But a few researchers stressed the perspective that the homelessness causes the lack of social support. This article analyzed empirically the lack of social support among the homeless in terms of "social disaffiliation". This article hypothesized: (a) as longer homeless duration, the extent of the perceived social support would be decreased, (b) as longer homeless duration, the magnitude of the social network would be decreased, (c) as longer homeless duration, the ratio of the homeless in social network would be increased. Survey data collected from 355 homeless persons (sheltered homeless) at 82 shelters in Seoul. The result of analysis supports 'social disaffiliation hypotheses'. The result of this study suggests that the social work intervention to strengthen social support and social network be critically important in homeless shelter.

The effects of various dietary fats on plasma lipids. liver lipids, and Plasma Peroxide levels were studied in rats fed for 6 wk with diets containing 15 wt% fat, as sesame oil. raw perilla seed oil. roasted perilla seed oil, heated perilla seed oil. mackerel oil or beef tallow. TBA values of these lipids during 4 wk storage, and linolenic acid contents of three kinds of perilla seed oil were also measured. Linolenic acid contents of raw perilla seed oil. roasted perilla seed oil and heated perilla seed oil were 62.3%, 61.6% and 53.1% respectively. Raw perilla seed oil showed the lowest rate of lipid peroxidation after 4 wk storage at 4$^{\circ}C$, and mackerel oil showed the highest peroxidation rate. The plasma cholesterol levels of rats consuming diets in which the carbohydrate was rice were not affected by n-3 PUFA. Rather, the degree of peroxidation seems to have a direct effect on cholesterol levels as shown by the hypocholesterolemic effect of raw perilla seed oil and beer tallow. However. the HDL-cholesterol level was greater in rats fed either roasted perilla seed oil or mackerel oil. Rats fed roasted perilla seed oil and raw perilla seed oil had lower levels of plasma triglycerides than rats fed beef tallow. In rats fed roasted perilla seed oil, the total lipid and cholesterol contents of liver were significantly lower than in those fed the other kinds of perilla seed oil. The plasma lipid peroxide levels were lower in rats fed either roasted perilla seed oil or beef tallow.

Numerous studies on the ablactation have been reported since Jundell’s report in 1924. This paper deals with the comparison in nutritional values, composition, economical sense and recommended dietary allowances to Korean infants of the weaning foods sold in Seoul, Jeonju and Gunsan together with the analysis of nutritional compositions of the most recommendable weaning food among those investigated. The results obtained from this study were; 1. Among ten kinds of the weaning foods produced in Korea, only nine sorts could be purchased in Seoul, seven in Jeonju and five in Gunsan. 2. It was difficult to compare directly the compositions of the weaning foods each other because of the differences of the unit indicated. 3. Not only the price of the same product in the same area was differentiated by 10 to 100 won but also the standard of nutritional composition was not identically indicated by the company produced. 4. Since the amount of directed dietary intake was much more than the actual nutritional requirements of Korean infants, waste of money was considered, if used according to the directions. 5. The nutritional compositions of the most recommendable weaning food among those investigated were indicated in Table. 6. More nutritious and economical weaning food adequate to Korean infants must be developed through further scientific, in vivo experiments.

This study is to investigate consequent nutrient intake status, influence of body mass index(BMI), and fat distribution on the silk amino peptide(SAP) and dietary fiber supplementation. During 2 months of this research (January to March, 2002), 45 women aged 20yr – 30yr (average age 24.6yr) were selected as subjects. Nutrient intake was investigated by questionnaire, 24-hr recall method. Antropometric assessments of the subjects were investigated by SBIA method(Segmental bioimpedance assay, In body 3.0). The results are as follows: mean body weight 57.7kg, mean body height 161.9cm mean BMI 22.0, and mean food habit score was 8.47. Defecation frequency was increased by dietary fiber supplementation. Frequency of pain during defecation was significantly decreased by dietary fiber supplementation (p<0.01). Feeling of residual feces was significantly improved by dietary fiber supplementation(p<0.001). Status of energy and carbohydrate intakes significantly decreased after dietary fiber supplementation(P<0.05). Body fat and WHR(waist hip ratio) significantly decreased after dietary fiber supplementation(P<0.001), and percent body fat was decreased by dietary fiber supplementation, significantly(P<0.05). Above results of this study show that dietary fiber-added routine diet improves defecation condition, and lessens body fat, percent body fat without losing body muscle. Especially, declination of abdominal fat and WHR were notable. That meant decreased risk factor.

This study was designed to investigated the antitumor effect and change chemosensitivity of chitosan in 2 kinds of humen lung cancer cell lines(NCI-H522, NCI-H596). To evaluate the antitumor effect and synergistic effectof chomosensitivity, MTT assay was used in vitro. then anticancer drugs used were 챤-platin , ectoposide, and adrimycin. The results of this study were as follows; Chitosan shwoed in antitumor effect on both NCI-H522 and NCI-H596. The lung cancer viability percent for NCI-H522 and NCL-H596 showed at the lowest levels of 5.31 and 5.33% when the concentration of chitosan was 25mg/$m\ell$ media and the exposure time of chitosan was 72 hours. ID50 value of chitosan on both NCI-H522 and NCI-H596 showed at the lowest levels of 14.07, 11.68 mg/$m\ell$ media when the exposure time of chitosan was 72 hours. the synergistic effect of chomosensitivity was better in NCI-H596 than in NCI0H522 . When the synergistic effect of chomosensitivity was shown according to the kind of the anticancer drugs, in case of NCI-H522 , in the concentration of 100$\mu\textrm{g}$/$m\ell$, ectoposide showed the highest synergistic effect of chomosensitivity and then was adrimycin In case of NCI-H596, in the concentration of 100$\mu\textrm{g}$/$m\ell$,, the order of the synergistic effect of chomosensitivity was ectoposide>adrimycin>cis-platin and in the concentration of 10$\mu\textrm{g}$/$m\ell$, ectoposide>cis-platin >adrimycin. It is concluded that chitosan is an active antitumor agent and is increased chomosensitivity though there is difference according to the kind and the concentration of anticancer drugs. But to be sued to lung cancer theraphy, further studies on toxicity, the mechanism of action, animal experiment are wanted.
