Eurya emarginata is an evergreen tree growing in the southern regions of Korea including Jeju Island. In this study, antioxidant and anti-photoaging effects were investigated with the extracts of E. emarginata leaves. As comparative studies with the extract and five solvent fractions, the EtOAc fraction showed the most effective DPPH and ABTS⁺ radical scavenging activities. The EtOAc fraction also inhibited matrix metalloproteinase-1 (MMP-1) production most effectively. Phytochemical study on the EtOAC fraction resulted in the isolation of three compounds; eutigoside C (1), eutigoside B (2) and quercitrin (3). Among the isolates (1-3), quercitrin (3) showed excellent antioxidant activities and inhibitory properties on MMP-1 production. Based on these results, it was suggested that extracts of E. emarginata leaves could be developed as natural anti-photoaging agents in cosmetic formulations.

Drug resistance is one of the most significant impediments to successful chemotherapy of cancer. Multidrug-resistance (MDR) is characterized by decreased cellular sensitivity to anticancer agents due to the overexpression of P-glycoprotein. By employing a resistant subline of HCT15 to adriamycin (CL02), we undertook the screening for agents which were effective to multidrug-resistant cancer cells. As a result, a myxobacterial strain JW150 was selected for study since an activity against CL02 cells was discovered in the strain. Cytotoxicity-guided fractionation of the culture broth led to the isolation of cystothiazole A and melithiazole F. The producing organism was identified as Myxococcus stipitatus by taxonomic comparison with type strains of Myxococcus sp. as well as its morphological and physiological characteristics. Cystothiazole A and melithiazole F demonstrated potent cytotoxicity against certain human cancer cells with $IC_{50}$ values ranging from 0.03~ $0.72{\mu}{\textrm{g}}$/ml. Both compounds were interestingly as active against drug-resistant sublines CL02 and CP70 as against the corresponding parental cells.

Ingestion of forage containing a large quantity of soluble oxalate can result in calcium deficiency and even death of livestock. Fertilization is one of the most practical and effective ways to improve yield and nutritional quality of forage. An experiment was conducted to determine the effects of nitrogen (N) fertilization (150, 300 and 600 kg/ha) across varying levels (150, 300 and 600 kg/ha) of potassium (K) on oxalate accumulation in napiergrass (Pennisetum purpureum). Application of N at 300 kg/ha produced higher dry matter yield than at 150 or 600 kg/ha, while K fertilization had no effect on yield. In general, N fertilization did not affect the soluble and total oxalate contents, but slightly affected the insoluble oxalate content. Soluble oxalate content showed an increasing trend and insoluble oxalate content showed a decreasing trend with increasing K level, but total oxalate content remained relatively constant. There were significant interactions between N and K fertilization for the content of soluble and insoluble oxalate fractions. The greatest increase in soluble oxalate content with N level at 300 kg/ha was found at the high level (600 kg/ha) of K application. The greatest increase in insoluble oxalate content with N level at 600 kg/ha was found at the low level (150 kg/ha) of K application. These results indicated the possibility of controlling the content of soluble and insoluble oxalate fractions in forage by fertilization.

The purpose of this study was to determine how often toddlers and preschoolers in kindergartens have accidents and what factors affect the accident rate. The study population consisted of 150 children who were attending at nursery schools and 150 children who were attending at kindergartens. The data was collected from ten nursery schools and five kindergartens from five districts in Daegu. The questionnaires were distributed to teachers of participating nursery schools and kindergartens to be completed using nursing care records in the institutions and by interviewing children's parents about all of the accidents happened in a previous year. Data were collected during the period of August 1 through 31, 2002. The results of the study are as follow: 1. Among 300 children, 282 had 506 accidental injuries during the study period. 2. The month, the day and the time with the highest accident rate were April. Monday, and between 2 and 4 o'clock in the afternoon, respectively. 3. Locations where the injury took place most included nursery schools or kindergartens, around the homes of the children, and inside the home. 4. Most accidents were occurred due to lack of carefulness of the children, and the most prevalent forms of injury was abrasions. 5. Most frequently injured part of the body was legs of the children. 6. Most injuries were healed within three days and required first aid measures to disinfect the wound. Mostly, these were performed by family members at home. Some children go to the hospital to suture the open wound. Most frequent type of complication was scar formation and the cost of the treatment ranged from 9,000 to 30,000 won. 7. Children's age. sex, birth order. personality. type of family composition. type of residency. father's occupation, father's age, and mother's age were significantly related to the frequency of injury among children. Children who were in nursery schools and kindergartens need their assessment for accident involving condition according to seasons, time. place. This study provided a very useful and important data to prepare accident prevention education program and accident prevention strategies, and to develop Injury Surveillance System.

Purpose: To investigate bone and disc configuration on MR images in internal derangement related to age. Materials and methods: MR images of 150 TMJs in 107 patients were analyzed to determine the morphologic changes. Two groups were distinguished to be correlated with age. Group I consisted of TMJs that were diagnosed as having anterior disc displacement with reduction (ADDwR), and Group 2 consisted of TMJs that were diagnosed as having anterior disc displacement without reduction (ADDwoR). We assessed the configuration of the articular disc, degree of anterior disc displacement, and osseous changes of TMJs. Results: The third decade (83 of 150 joints) was most frequent in this study. In the ADDwR group biconcave discs was most frequent at all ages except fifth decade, but in the ADDwoR group deformed discs was most frequent at third and forth decades. In the ADDwR group slightly displaced discs was most frequent at all ages, but in the ADDwoR group severely displaced discs was most frequent at second decade, and the degree of disc displacement was increased with aging over 30 years of age. TM joints showed osseous changes in 17% of the ADDwR group, and in 30% of the ADDwoR group. MR findings of osseous changes of the TMJ were not found to be significantly correlated with age. Conclusion: The prevalence of deformation of disc, displacement of disc, and osseous changes of TMJ was higher in the ADDwoR group than in the ADDwR group. MR findings of disc configuration and degree of disc displacement were found to be correlated with age.

We surveyed 848 university students, $21.4{\pm}2.5$ years of age, attending university in Seoul, Kongju, Chongyang-Gun in the Chungnam province of Korea, for their use of health functional foods (HFF) and for significant variables in this use, namely demographic characteristics, health related variables, dietary variables and nutritional beliefs. The prevalence of the use of HFF was 33.6%. Among all types of HFF, nutritional supplements were taken most frequently, followed by (in order) red ginseng products, apricot extract products and ginseng products. HFF use was higher in females (p<.05), in subjects living in a dormitory (p<.05) and those from families with a relative high socioeconomic status (p<.001). Self-health concern (p<.05) and usage ratio of HFF by family (p<.001) was higher in users than in nonusers of HFF. The total score of dietary assessment was higher in users than in nonusers of HFF (p<.001), and users had a more positive point of view concerning the potential health benefits of HFF than did nonusers (p<.001). Most users took HFF when they were healthy (37.2%) or when they were sick (27.4%). They did not feel special effects through the HFF use (49.8%). Most users got the information about the specifics of HFF from family and/or relatives (55.8%). Most of users confirmed nutrition facts when they purchased the HFF (70.9%), but a considerable number of users could not understand these nutrition facts (48.1%). Users preferred vitamin C- and Ca-supplements most among vitamin mineral supplements belonged to HFF. These results show that the use of HFF is common among university students. As well, the use of HFF by students is affected by various variables. Supplementary nutritional education should be undertaken among university students, in order to give them a reasonable guideline for the use of HFF, based upon influencing factors and usage behaviors that we learned from this survey.
