There is increasing evidence that dietary factors in plant-based diets are important for the prevention of chronic disease. Especially, phytonutrients in fruits and vegetables have been recognized as major contributors for the decreased level of oxidative stress. In this study, the effect of switching the dietary habit to high consumption of fruits and vegetables were evaluated on the parameters of serum antioxidant status in healthy high school students. Forty one students participated in a randomized controlled trial and were assigned to the control group (n = 18) or the intervention group (n = 23). The intervention group was provided for 8 weeks with the main food source being whole grain and vegetables. Anthropometric measurements, blood parameters and dietary intakes were measured, and compared before and after study. After 8 weeks, weight and BMI were significantly decreased in the intervention group (p = 0.000). The serum diacron reactive oxygen metabolites (d-ROMs) test resulted in a significantly decreased level only in the intervention group (p < 0.05) after 8 weeks, but serum biological antioxidant potential (BAP) was increased significantly in both groups (p < 0.001). Intake of energy, total fat, cholesterol and sodium in the intervention group were significantly decreased after 8 weeks (p < 0.05). Also, the intervention group had significantly increased vitamin and phytonutrient intakes of all-trans-${\beta}$-carotene, ${\alpha}$-carotene, ${\alpha}$-tocopherol, ascorbic acid, and total phenols (p < 0.05). Overall, the results of this study suggest that whole grain, fruits, and vegetables supplementation showed improvement of the adolescent health.

8체질의학과 질병생태학은 질병의 원인을 병균 이외의 유전적 요인, 환경적 요인, 문화적 요인의 상호관계, 즉 인간과 환경의 관계에서 접근한다는 점에서 상당한 유사성을 공유한다. 본 연구에서는 한의학의 8체질의학과 지리학의 질병생태학 간의 공통성을 실증적으로 검토하는 것을 목표로 두었다. 한의원을 내방하는 환자 647명의 임상 데이터와 전라남도 영광군의 사례를 분석하고 검증한 결과 도출된 내용은 다음과 같이 요약된다: 첫째, 각 시도별로 체질의 지리적 분포는 상이하게 나타나며, 이러한 분포 양상은 크게 해양형과 내륙형으로 분류할 수 있다. 둘째, 체질에 따라 잘 걸릴 수 있는 질환과 태생지의 상호관련성은 비교적 큰 것으로 파악되었다. 그렇지만 특정한 질환이 모든 체질에게 동일하게 발생하는 것이 아니라 지리적 환경의 특성에 영향을 받는 식생활이나 생활습관에 따라 사람들에게 차별적으로 발생하는 것으로 보인다. 셋째, 유전, 자연환경, 문화 등 요인의 상호연관성을 면밀하게 분석하기 위하여 전라남도 영광군의 사례를 실험적으로 분석해 보았다. 그 결과 자신의 체질에 맞는 식습관이나 생활습관을 가지고 있는 경우에는 비교적 건강한 상태를 유지하고 있었지만, 그렇지 않은 경우에는 다양한 질환에 노출되어 있었다. 8체질의학과 질병생태학의 공통성에 관한 연구는 아직 초기 단계에 있으므로 앞으로 이러한 공통성을 규명하는 방법과 노력이 다양하게 개발되고 투여되어야 할 것이다.

The distributions of G to A substitution ($G^{-75}{\rightarrow}A$) mutation in the human apolipoprotein A1 (APOAI) gene promoter region and glutathione S-tran-sferase Mu1 (GSTM1) gene deletion were examined in subjects with Korean population. The $G^{-75}{\rightarrow}A$ mutation of APOA1 was genotyped by the polymerase chain reaction (PCR) and subsequent digestion of the PCR product using either Mspl or Mval (n=206). The observed numbers of GG, GA and AA genotypes were 132, 63 and 11, respectively. The allele frequencies of G and A were 0.794 and 0.206, respectively. The GSTM1 gene deletion was simply examined by the PCR amplification (n=106). The observed numbers of null type ($GSTM1^*0/GSTM1^*0$) and positive type were 55 and 51, respectively. The allele frequency of $GSTM1^*0$ was 0.720.

This study was investigated the anti-oxidant property and neuro-protective effect of Cirsium japonicum var. maackii (CJM) against oxidative stress in hydrogen peroxide ($H_2O_2$)-induced C6 glial cells. We measured the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, hydroxyl radical (${\cdot}OH$), and superoxide ($O_2{^-}$) radical scavenging activities of an ethanol extract and four fractions [n-Butanol, ethyl acetate (EtOAc), $CHCl_3$, and n-Hexane] from CJM. The results of this study show that the extract and all fractions from CJM had a dose-dependent DPPH radical scavenging activity. In particular, the EtOAc fraction exhibited the strongest scavenging effect with 88.23% at a concentration of $500{\mu}g/mL$. In addition, the EtOAc fraction from CJM also effectively scavenged ${\cdot}OH$ radicals and $O_2{^-}$ radicals, compared to other extract and fractions. In C6 glial cells, $H_2O_2$ markedly decreased the cell viability as well as increased lactate dehydrogenase (LDH) release and reactive oxygen species (ROS) production. However, the EtOAc fraction of CJM attenuated the cellular damage from the oxidative stress by elevating the cell viability and inhibiting the LDH release and ROS over-production compared with the $H_2O_2$-treated control group. Our findings indicate that the EtOAc fraction from CJM has antioxidant effect and neuro-protective effect against oxidative stress, suggesting that it can be used as a natural antioxidant and therapeutic agent for the prevention of neurodegenerative disorders.

The effects of pentylenetetrazol (PTZ), a GABA receptor antagonist, were studied on passive avoidance learning and expression of heat shock protein 70 (hsp70), neuroglobin, and fatty acid binding protein-7 (fabp-7) genes. Zebrafish were trained to stay in a dark compartment to avoid a weight dropping in an acryl shuttle box with a central sliding door. In two training sessions of 2 h interval, each consisting of 3 trials, the crossing time was significantly increased from $43.2{\pm}14.4s$ to $149.3{\pm}38.5s$ in the first training session and remained $116.1{\pm}36.0s$ s in the first trial of the second training session in the control. In zebrafish treated with PTZ before the first training session, the crossing time was significantly increased neither in the first nor in the second training session. However, the increased crossing time was maintained in the second training session when 10 mM PTZ was treated three times for 10 min at 30 min intervals between the first and second training session. Quantitative real-time PCR showed that expression level of hsp70 mRNA increased two to eight fold over that of control in the brain at 0-24 h after termination of PTZ treatment. No change in expression of neuroglobin and fabp-7 mRNA was shown in PTZ-treated zebrafish. Our studies suggest that PTZ impairs learning ability in avoidance response and also modifies expression of genes related to the neuroprotection.

The nucleotide sequences of a male-specific marker sex determining region Y (SRY) gene and a mitochondrial cytochrome B (CYTB) gene were characterized and analyzed to establish a molecular method for identification of species and sex of Korean roe deer (Capreolus pygargus tianschanicus). Similarity search result of SRY sequences showed very similar result to those reported in Moose (Alces alces) and Reindeer (Rangifer tarandus), both of which had 95.9% similarity in identity. CYTB genes were very similar to those reported in Siberian roe deer (C. pygargus pygargus) which had 98.6% similarity and not to European roe deer (C. capreolus), suggesting that the DNA samples tested were of Siberian roe deer lineage. Polymerase chain reaction (PCR)-based sex typing successfully discriminated between carcasses of male and female roe deer. Males had SRY band on agarose gels and females did not. The result of this molecular sex typing provided similar information with that obtained by genital organ observation. Therefore, this molecular method using male specific marker SRY and mitochondrial CYTB genes would be very useful for identification of the species and sex of the carcass remains of roe deer.

Purpose: The purpose of this study was to describe the subjective happiness and satisfaction with life of children with type 1 diabetes and explore related factors. Methods: A descriptive cross-sectional study design was used and the study was conducted with children at a diabetes camp. Data were collected using a self-report questionnaire to explore positive and negative psychological factors. The questionnaire included Subjective Happiness Scale, Satisfaction with Life Scale, Perceived Stress Scale and the Center for Epidemiological Studies Depression Scale for Children (CES-DC), Multidimensional Scale of Perceived Social Support, and General Self-Efficacy Scale. Results: Data from 15 children were used for data analysis. The correlational analysis results showed that subjective happiness was positively correlated satisfaction with life, social support, and self-efficacy, and was negatively correlated with perceived stress. Satisfaction with life was positively correlated social support, and was negatively correlated with perceived stress. Conclusion: Results indicate that the positive psychology factors were closely related with social support and self-efficacy and may alleviate perceived stress and depressive feelings. Therefore, researchers and clinicians should include positive psychological factors in their health management model for children with chronic illness.
