Paeoniae radix is commonly used for various woman's health problems in traditional korean medicine. In order to develop new antioxidant for woman use. the ethanolic extracts of paeoniae radix (PRE) were prepared and various biological activities were evaluated. PRE showed potent free radical scavenging activity and moderate antioxidative activity in vitro. and also showed the protective effect on H2O2-induced DNA damage in mammalian cell. (omitted)

Purpose: This study was conducted to examine the level of physical activities at time points of pre-illness and current treatment, and the differences in body mass index (BMI), anxiety, depression and fatigue according to their physical activity in cancer patients undergoing chemotherapy. Methods: The survey was used with 126 cancer patients undergoing daily chemotherapy at injection room, cancer clinic of C University Hospital in G city. Data were collected from June to September, 2009 using a structured questionnaire. The data were analyzed by descriptive statistics, chi-square, Fisher's exact test and t-test using SPSS/WIN15.0. Results: The significant increase in physical activity was reported from pre-illness to the time in treatment (${\chi}^2$=69.027, p<.001). The anxiety level of the group with increased physical activity was significantly lower than those who did not (t=-2.218, p =.028). There were no significant differences in BMI, depression, and fatigue according to physical activity. Conclusion: The level of physical activity was significantly associated with the anxiety level of the cancer patients undergoing chemotherapy. Cancer patients should been encouraged regular physical activity during chemotherapy treatment. And an appropriative nursing intervention should be established in order to motivate cancer patients to increase physical activity.

Objective: This study aimed to explore the experience and meaning of pre-service early childhood teachers who practiced health promoting activities for themselves. Methods: Research participants were 115 pre-service early childhood teachers enrolled in the health education for children course at one college in G region. The reports of activity records of their eight-week long health promotion activities were collected as qualitative data followed by content analysis being implemented. Results: First, the experience of the health promoting activities the participants took part in was categorized into 'Early phase of experience: A mix of worries and anticipation, and success and failure', 'Mid phase of experience: Being motivated by physical changes and records', and 'Late phase of experience: Continuous execution through habituation.' Second, the meaning of health promotion activities the participants took part in was categorized into 'A great opportunity for introspection', 'A meaningful start of college life', and 'A valuable chance to consider desirable roles of a teacher for early childhood health education.' Conclusion/Implications: The results of this study suggest that pre-service early childhood teachers should pay close attention to their health management, and that contents that emphasize the importance of teachers' health should be included in health education.

IL-33 is a member of the IL-1 cytokine family and plays a role in the host defense against bacteria, viruses, and fungi. In this study, we investigated the function of IL-33 and its receptor in in vitro macrophage responses to Candida albicans. Our results demonstrate that pre-sensitization of isolated peritoneal macrophages with IL-33 enhanced their pro-inflammatory cytokine production and phagocytic activity in response to C. albicans. These macrophage activities were entirely dependent on the ST2-MyD88 signaling pathway. In addition, pre-sensitization with IL-33 also increased ROS production and the subsequent killing ability of macrophages following C. albicans challenge. These results indicate that IL-33 may increase anti-fungal activity against Candida through macrophage-mediated resistance mechanisms.

This study was intended to investigate the effects of nutritional, physical and environmental conditions on the bone status of 102 pre and post menopausal women living in Ulsan area. The results of this study are summarized as follows : when subjects were classified into two groups by bone status, there were significant differences in age, calcium index, serum estrogen and physical activity between two groups. Average daily calcium intake of subjects was 682.9 (149.2)mg, which is almost same as RDA, but 41.1% of the subjects consumed calcium below RDA. Calcium index(p<0.05), serum estrogen(p<0.001), physical activity(p<0.001) of poor bone group were significantly lower than those of good bone group. Although there was not a significant difference between bone status and other influential factors, such as family type, skip meal, alcohol drinking, smoking and BMI, each has been shown to have an effect, if slight, on the bone status.

왕겨 10 g에 5종류(초산, 구연산, 젖산, 인산, 주석산)의 50 mM 유기산 100 mL을 가하여 18시간 동안 상온에서 방치한 후, $121^{\circ}C$에서 30분간 수열처리 하여 왕겨 추출물을 제조한 후 항산화능을 측정하였다. 대조구로 증류수를 사용한 경우에 총 페놀 함량, DPPH 라디칼 소거능, 환원력, ABTS 라디칼 소거능은 각각 0.44 mg/mL, 70.97%, 1.00 OD, 88.98%이었으며, 비교적 효과가 좋았던 인산의 경우에는 각각 0.82 mg/mL, 81.34%, 1.18 OD, 64.03%로 측정되었다. 인산의 농도별 전처리 효과를 보기 위해 10, 25, 50, 100 mM의 농도에서 같은 조건으로 왕겨 추출물을 제조하여 항산화능과 관련된 지표를 분석한 결과, 총 페놀 함량과 DPPH 라디칼 소거능은 인산 농도가 증가할수록 증가하는 경향을 보였으나, 환원력은 인산의 농도가 증가할수록 감소하는 경향을 나타내었으며 ABTS 라디칼 소거능은 50 mM 인산 농도까지는 인산의 농도가 증가할수록 감소하였으나 100 mM 인산에서는 다시 증가하였다. 이상의 결과로 왕겨에 존재하는 페놀성 항산화물질을 유기산 전처리로 효율적으로 유리화시킬 수 있음을 확인하였다.

식재료로서 안전성이 확립되고 항산화성이 입증되어 있으며, 유익한 생리활성을 나타내는 성분을 동시에 섭취할 수 있는 과일 및 야채의 복합 추출물을 항산화 활성이 더욱 증가하도록 가공한 항산화성 복합 추출물의 항산화 활성을 평가하였다. 실험 결과에 의하면 항산화성 복합 추출물은, 사전 열처리 과정을 추가하는 것에 의해 DPPH 라디컬 소거능으로 측정되는 항산화능이 41% 증가하여 항산화성이 현저하므로, 항산화능을 이용한 약학 조성물, 화장료 조성물 또는 식품 조성물에 유용하게 사용될 수 있다는 결과를 얻었다.

동일한 벼 품종은 수분함량이 다른 토양에서 재배했을 경우, 도열병에 대한 감수성에 차이가 생기는데 그 원인을 조사하기 위하여 잎 표피에서 분생포자발아 및 부착기형성까지의 도열병균 침입전 행동을 광학현미경과 주사전자현미경(SEM)으로 관찰하였다. 수분함량이 다른 토양에서 자란 벼 잎 사이에 표피세포의 외부형태, 잎 표피에서의 분생포자발아관의 생장 및 생장방향, 부착기의 형태 및 크기는 차이가 없었다. 부착기는 토양수분처리와 상관없이 기동세포$(35\~48\%)$위에 가　 많이 형성되었고 단세포$(19\~27\%)$, 장세포 및 공변세포$(13\~20\%)$의 순이었다. 모분상의 부착기형성은 관찰되지 않았다. 본 시험결과, 수분함량이 다른 토양에서 자란 벼 사이에 나타나는 도열병에 대한 감수성의 차이는 도열병균의 침입전 행동에서 기인하는 것이 아닌 것으로 생각된다.

This study examines the effects of Evening primrose on colors, color fastness, and the antimicrobial activity of dyed fabrics. The results are as follows. The dyeing conditions of Evening primrose on cotton and mercerized cotton were optimized at $50^{\circ}C$, 60 minutes, and 200% (o.w.f.). In addition, Evening primrose dyeing on silk was determined at $90^{\circ}C$, 60 minutes and 200% (o.w.f.). The pre-mordant concentration of chemicals of cotton, mercerized cotton and silk was optimized at 1% (o.w.f.). The post-mordant concentration on mercerized cotton, silk and cotton was determined at 1% (o.w.f.) and 3% (o.w.f.), respectively. The mordant methods (such as pre-mordant and post-mordant) were slightly affected on the hue of dye-fabrics. Wet cleaning fastness of cotton was improved by post-mordant; otherwise, the wet cleaning fastness of mercerized cotton and silk was improved by a pre-mordant. The dry cleaning fastness of cotton and silk was excellent regardless of mordant methods. The dry cleaning fastness of mercerized cotton was improved by a post-mordant compared to a pre-mordant. The antimicrobial activity of Evening primrose-dyed fabrics was shown at 99.9%. The excellent antimicrobial activity of dyed fabrics remained after the mordant as well as wet and dry cleaning.
