To test the quality change of seedlings of three domestic medicinal plants raised in plug trays, a short term storage experiment was conducted. Seedlings were kept in growth chambers for two weeks at 4 or $8^{\circ}C$ temperature combined with 0 or $5{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD. Quality of glasshouse-raised seedlings was assessed after two weeks of cold storage in the growth chamber and one week of acclimation in the greenhouse. After two weeks of storage in the growth chamber of Perilla frutescens var. acuta Kudo, plant height was the greatest in the treatment $8^{\circ}C$ combined with $0{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD. Internode length of P. frutescens var. acuta Kudo was the greatest in the treatment of $4^{\circ}C$ combined with $0{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD. After one week of acclimatization in a glasshouse, the growth and development, such as plant height, internode length and leaf size, were greater in the $8^{\circ}C$ combined with $5{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD than in the other treatments. After two weeks of storage in the growth chamber of Sophora tonkinensis, plant height increased more in the treatment of $4^{\circ}C$ than $8^{\circ}C$. After one week of acclimatization in a glasshouse, number of leaves did not change in the treatment of $4^{\circ}C$ combined with $0{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD, but it increased in the other treatments. Leaf width increased more under the dark than light condition. Leaf length did not observably change in any treatments. After two weeks of storage in the growth chamber, plant height of Angelica gigas Nakai was the greatest in the treatment of $8^{\circ}C$. Number of leaves was the greatest in the treatment of $8^{\circ}C$. Leaf growth was greater under dark than light condition. These results suggested that optimal storage environment was $8^{\circ}C$ combined with $5{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD for P. frutescens var. acuta Kudo, and $4^{\circ}C$ combined with $0{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ PPFD for S. tonkinensis and A. gigas Nakai. Hence, proper combination of temperature and PPFD were necessary for better storage, and acclimatization and growth, thereafter, of the plug seedlings of theses plant species.

Background: Even after completion of conventional treatment, breast cancer survivors continue to exhibit a variety of psychological and physical symptoms, affecting their quality of life. The study aimed to investigate the relationship between socio-demography, medical characteristics and health-related quality of life (HR-QOL) of a sample of breast cancer survivors in Malaysia. Materials and Methods: This pilot cross-sectional survey was conducted among breast cancer survivors (n=40) who were members of Breast Cancer Support Group Centre Johor Bahru. A validated self-administered questionnaire was used to identify the relationships between socio-demography, medical characteristics and HR-QOL of the participants. Results: Living with family and completion of treatment were significant predictive factors of self-rated QOL, while living with family and ever giving birth significantly predicted satisfaction with health and physical health. Psychological health had moderate correlations with number of children and early cancer stage. Survivors' higher personal income (>MYR4,500) was the only significant predictor of social relationship, while age, income more than MYR4,500 and giving birth significantly predicted environment domain score. Conclusions: The findings suggested the survivors coped better in all four HR-QOL domains if they were married, lived with family, had children and were employed.

본 연구에서는 실험동물에 민들레 열수추출물 식이를 급여한 후, GalN으로 간손상을 유발함으로써 그 예방효과를 혈액중의 생화학적 변화 및 간조직의 효소적인 변동을 통해서 규명하고자 하였다. GalN의 투여로 현저히 증가하였던 AST, ALT의 활성은 민들레 열수추출물 투여로 억제되었으나 군간의 차이는 보이지 않았고 ALP의 활성과 TBARS 함량은 3%의 추출물을 급여한 군에서 유의적인 감소를 보였다. GalN의 투여로 현격하게 높아졌던 혈중 $TNF-{\alpha}$의 농도 또한 감소하는 경향을 확인하였으나 유의적인 차이는 보이지 않았다. GalN의 투여로 억제되었던 catalase, GSH-reductase, Mn-SOD의 활성은 민들레 추출물 투여로 유의적인 회복이 관찰되었으나 GSH-px의 활성은 그 경향만을 확인할 수 있었다. 조직 검경을 통해 민들레 열수추출물의 간염 예방효과를 확인한 결과 GalN으로 인해 유발된 광범위한 간세포의 괴사와 변성, 지방변성 등이 민들레 열수추출물식이로 다소 감소하는 것을 관찰할 수 있었다. 이상의 결과로 민들레 열수추출물은 AST, ALT와 ALP의 활성 및 산화적 스트레스를 감소시키고 활성산소 해독계에 관여하는 효소의 활성을 증가시킴으로써 GalN으로 인한 간 손상을 예방하는 것으로 사료된다.

The effects of a newly developed flower thinning formulation (FTF) on the vitality of the honey bee Apis mellifera were examined by measuring the activities of various digestive enzymes in adult worker bees. First, direct spraying of the FTF solution did not cause any behavioral changes or lethal effects for the honey bees based on 24 h observation. Second, oral ingestion of a sugar solution containing the FTF did not produce any significant change in the activities of amylase, proteinases, lipase, or acetylcholine esterase (AChE) in the worker bees 6 h or 24 h after treatment. Meanwhile, a commercial formulation containing sulfur compounds showed slightly reduced activities for several digestive enzymes and AChE, although no behavioral disturbance. Thus, the results of the present study suggest that the FTF is not toxic for honey bees, in terms of contact and ingestion. Therefore, this newly developed FTF can be used for flower thinning without any detrimental effects on pollinating insects.

본 연구에서는 습식 나노화 공정 기술을 적용하여 제조한 식물영양제를 이용하여 사과 잎에 흡수되는 칼슘과 마그네슘의 이동 경로 및 흡수율을 비교 분석하였다. 습식 나노화 공정을 통해 불용성 칼슘과 마그네슘을 나노화 처리한 식물영양제의 성분 함량 및 이동경로를 확인하기 위하여 식물 영양제 살포 후 2주, 4주 및 8주 경과 후 잎자루, 잎몸, 옆면으로 구분하여 SEM, EDS 촬영을 통해 분석하였다. 잎자루는 식물 영양제 살포 후 4주차부터 증가하여 8주차에서는 1,115%까지 증가했으며, 사과 잎몸의 경우 2주차의 미살포구에 비해 살포 후 칼슘과 마그네슘의 함량이 감소하였으나, 4주 이후부터는 증가하였으며, 4주차의 뒷면 증가율이 539%로 가장 높았다. 또한, 잎몸의 옆면은 미살포구에 비해 살포구 모두 칼슘과 마그네슘 함량이 증가하였는데 특히, 4주차에 673% 증가하여 가장 높은 증가율을 보였다. 시간이 경과함에 따라 모든 살포구가 미살포구에 비해 칼슘, 마그네슘 함량이 점점 증가하여 나노화 식물영양제의 불용성 칼슘과 마그네슘 성분이 사과의 잎자루에서 잎몸까지 이동한 것으로 판단된다. 본 연구 결과를 보았을 때 습식 나노 공정 기술을 통해 제조된 식물영양제를 활용하면 사과 이외의 다른 작물 에서도 칼슘과 마그네슘 흡수 효과를 얻을 수 있을 것으로 판단하였다. 또한, 식물영양제 이외에도 천연물이나 바이오산업에도 나노 공정 기술의 적용이 가능할 것으로 기대된다.

Objectives : This study examined the relationship of parent-related negative life events with mental health and delinquent behaviors among Korean adolescents. Methods : A total of 2,976 high school first-grade pupils (1,498 boys & 1,478 girls) taking part in the third wave of Korean Youth Panel Survey completed a self-administered questionnaire regarding parent-related life events, depressive feelings, suicidal ideation, delinquent behaviors, demographic characteristics, parental socioeconomic status, social support, and social capital. Data analyses were conducted using multivariate logistic regression. Results : After adjusting for all covariates, the more parent-related negative life events adolescents experienced throughout their whole life, the more likely adolescent were to have mental and behavioral problems. A significant dose-response relationship between them was more clearly observed in girls than in boys. The experience of parentrelated negative events during childhood was significantly associated with suicidal ideation and delinquent behaviors for boys, and with depressive feelings for girls during adolescence. Indeed, parental social support, social capital, and having a close friend with delinquent behaviors, especially for girls, partially mediated the relationship between parent-related negative life events and both outcomes. Conclusions : The study showed a clear dose-response relationship of frequency of parent-related negative life events with poor mental and behavioral health for both genders. The residual effect of being exposed to parent-related events during childhood on mental health and delinquent behaviors during adolescence still remained.

Objectives: The purpose of this study is to report two cases of prostate cancer patients whose side effects after surgery were treated with traditional Korean medicine. Methods: Two prostate cancer patients underwent robot-assisted laparoscopic prostatectomy, and both patients were treated with traditional Korean medicine. Subjective discomfort symptoms were evaluated using the Numerical Rating Scale. Adverse events were evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 5.0. Daily life vitality was evaluated by the Eastern Cooperative Oncology Group. Results: After treatment with traditional Korean medicine, discomfort symptoms that occurred after surgery, such as frequent urination, nocturia, insomnia, and depression, all gradually improved, and Eastern Cooperative Oncology Group scores also improved from two points to one point. Additionally, there were no hematologic side effects from the traditional Korean medicine treatment. Conclusions: This case study suggests that traditional Korean medicine may contribute to the improvement of side effects caused by robot-assisted laparoscopic prostatectomy, quality of life, and immunity.
