  • 홍삼은 인삼을 찌고 말리는 과정을 거쳐 제조한 것으로 많은 약리 및 생리활성이 알려져 있다. Cisplatin은 항암제로 사용되고 있으나 부작용으로 골수억제, 위장관계독성, 신경독성, 신독성 등이 보고되어있다. 특히 cisplatin이 신장에 집중적으로 축적됨으로써 투여환자의 25-30%에서 신장독성이 유발된다. 따라서 본 실험에서는 발효홍삼을 이용한 cisplatin의 부작용인 신독성예방효능을 확인하고자 하였다. 시료에 따른 DPPH와 ABTS 라디칼소거능을 실험 결과 RG8F3에서 가장 우수한 소거능을 확인하였고 따라서 RG0SF0와 RG8F3 간의 비교실험이 가능할 것으로 사료되었다. 동물실험은 정상군, 대조군, RG0SF0 투여군 및RG8F3 투여군 4그룹으로 나누었다. 약물투여군은 200 mg/kg/day의 농도로 4일간 투여한 후,cisplatin은 20 mg/kg으로 대조군 및 약물투여군에복강주사하였다. RG8F3 투여한 결과 대조군과 비교하여 GSH의 수치는 증가하였고 ROS, BUN, creatinine 및 염증인자들의 감소를 보였다. 조직학적 결과에서도 신손상으로 인한 변형이 거의 없었다. 결론적으로 발효홍삼은 cisplatin으로 유발되는 신 손상 예방에 유의한 효과를 보이는 것으로 사료된다.

  • This study analyzes the characteristics of the motifs and colors in flower and bird paintings which contain and present Korea's unique aesthetics based on its richest data among all other types of Korean folk paintings. With a theoretical exploration of folk paintings and an analysis of the motifs and colors, textile design with an aim to present highly valued korean modern fashion design was developed. Two hundred and seventy flower and bird paintings were selected from relevant materials, resulting in an extraction of 5,068 colors. A palette of representative colors was made based on densely distributed hues and tones. The research can be summarized as follows: Flower and bird paintings contain flowers, birds, trees and animals and the motifs in the paintings stand for spirituality, philosophies from different times and other symbols of our nation. Each of the motifs in these paintings is a prayer for good luck, especially conjugal harmony and fecundity to bring about happiness and richness. Colors in flower and bird paintings are characteristic of the order: YR(25.5%)>R(19.2%)>Y(10.6%)>PB(9.2%)>G(7.9%), with low-chromatic YR and highly bright R taking up a larger percent. The order of tones is: d(13.5%)>dk (10.5%)>s(10.4%)>dkg(10.0%)>sf(9.1%)and the tone is dark in general. YR, taking up the largest percent, was dull, light, and soft. As for the achromatic colors, the order is: W(5.2%)>Gy(1.9%)>Bk(0.7%). Based on the above analyzed color data, those colors which were high in their hue and tone were extracted to present representative colors. In this way, representative colors like yellow, yellowish red, red, green, and purplish blue were extracted. This was the basis to present motifs and colors originating from subjects of folk paintings in various patterns using Illustrator CS6, to create modern fashion design.

  • Four-and-a-half LIM-only protein 3 (FHL3) is a member of the LIM protein superfamily and can participate in mediating protein-protein interaction by binding one another through their LIM domains. In this study, the 5'- and 3'- cDNA ends were characterized by RACE (Rapid Amplification of the cDNA Ends) methodology in combination with in silico cloning based on the partial cDNA sequence obtained. Bioinformatics analysis showed FHL3 protein contained four LIM domains and four LIM zinc-binding domains. In silico mapping assigned this gene to the gene cluster MTF1-INPP5B-SF3A3-FHL3-CGI-94 on pig chromosome 6 where several QTL affecting intramuscular fat and eye muscle area had previously been identified. Transcription of the FHL3 gene was detected in spleen, liver, kidney, small intestine, skeletal muscle, fat and stomach, with the greatest expression in skeletal muscle. The A/G polymorphism in exon II was significantly associated with birth weight, average daily gain before weaning, drip loss rate, water holding capacity and intramuscular fat in a Landrace-derived pig population. Together, the present study provided the useful information for further studies to determine the roles of FHL3 gene in the regulation of skeletal muscle cell growth and differentiation in pigs.

  • Rotavirus is a major cause of severe gastroenteritis in young children and animals throughout the world. The VP7 of rotavirus is thought to induce the synthesis of neutralizing antibodies and to be responsible for determining viral serotypes. The cDNA coding for the VP7 capsid protein of human rotavirus, obtained from Korean patients (HRV-Y14), was cloned and its nucleotide sequence was determined. Comparative analysis of the nucleotide sequences between VP7 of Y14 and that of other foreign isolates showed $92.7~95.2\%$ homology to G1 serotypes (RV-4, KU, K8, WA), $74.2\%$ homolgy to G2 serotype HU-5, $76.4\%$ homology to G3 serotype SA-11, and $77.6\%$ homology to G4 serotype A01321. These data suggest that HRV-Y14 can be classified as a G1 serotype. cDNA coding for VP7 of HRV-YI4 was subcloned into the baculovirus vector and the VP7 glycoprotein was expressed in insect cells. The expressed proteins in Sf9 cell extract and tissue culture fluid were separated on SDS-PAGE, and Western blot analysis with monoclonal antibody raised against the synthetic peptide containing 21 amino acids within the VP7 conserved region was performed. The molecular weight of recombinant VP7 was estimated to be 36 kDa which is about the same size as the native VP7. Addition of tunicamycin in the culture media caused a reduction of the molecular weight of the recombinant VP7 indicating that the expressed protein was glycosylated.

  • Objectives The aim of this study was to explore the effect of parental attitude on the behavioral problems in children who visited the traditional Korean pediatrics clinic. Methods The subjects were consist of 190 outpatients ($56.6{\pm}12.9$ months) and their mother. The Behavior problems of children were measured with Korean version of Child Behavior Checklist for Ages 1.5-5 (K-CBCL1.5-5) while parental perception of child vulnerability, parent overprotection, parenting stress were measured by Child Vulnerability Scale (CVS), Parent Protection Scale (PPS), Korean-Parenting Stress Index-Short Form scale (K-PSI-SF), respectively. Correlation and multiple regression were conducted for the analysis. Results Significant correlations between child total problems score and child vulnerability (r=.272, p<.001), parent overprotection (r=.243, p=.001), and parenting stress (r=.597, p<.001) were reported. Multiple regression analysis revealed that the parenting stress (${\beta}$=.548, p<.001) was a major predictor for the child behavior problems rather than child vulnerability and parent overprotection. Conclusions It was shown that the parenting stress has a significant influence on the emotional and behavioral development of children. These results can be useful for improving clinical diagnosis and treatment in traditional Korean pediatrics.

  • Objectives There are only a limited number of studies on instruments assessing fatigue in university students, although fatigue exerts negative influences on their health and academic performances and fatigue-related complaints are more frequently reported in young adults than middle-aged adults. The aim of this study was to validate the 9-item Fatigue Severity Scale (FSS) among university students including both undergraduate and graduate students in South Korea. Methods A total of 176 university students completed a battery of self-report questionnaires, including the FSS, the Brief Fatigue Inventory (BFI), the Beck Depression Inventory-II (BDI-II), the Beck Anxiety Inventory (BAI), the Medical Outcomes Study Short Form 36 version 2 (MOS-SF36v2), and the Inclusion of Community in the Self Scale (ICS). The data were collected from February of 2012 to June of 2012. The reliability, convergent validity, divergent validity, and exploratory factor analyses were conducted to assess psychometric properties of the FSS. Results The mean FSS score was 3.20 (standard deviation = 1.43). The FSS demonstrated an excellent internal consistency (Cronbach's ${\alpha}$ = 0.93) and item-total correlations ranged from 0.56 to 0.90. Correlations of the FSS with the BFI (r = 0.71, p < 0.01), BDI-II (r = 0.54, p < 0.01), BAI (r = 0.46, p < 0.01), MOS-SF36v2 physical component summary (r = -0.28, p < 0.01), MOS-SF36v2 mental component summary (r = -0.55, p < 0.01), and ICS (Spearman's rho = -0.07, p = 0.33) showed acceptable convergent and divergent validity. Exploratory factor analysis defined one underlying factor (eigenvalue = 5.67) that explained 93.50% of the total variance. Conclusions To the best of our knowledge, this is the first study to investigate reliability and validity of the FSS in university students. The FSS exhibits good psychometric properties for evaluation of fatigue among university students in South Korea. Since the FSS is easy to administer, score, and interpret, it could be a useful tool in research and practice for assessing fatigue among university students.
