This study was planned to suggest countermeasure of nutrition education by investigating adolescents, dietary behavior, food weight, and acknowledgement of food calories. 210 middle school boys were selected and asked to fill out the questionnaire. The subjects were divided by nutrition education experience; 1st grade who received nutrition session and 3rd grade who divided subjects. In terms of acknowledgement of food calories subjects nutrition education experience had more recognition for calories than the other group(p<0.01). When one bowl of rice, a potato, a bowel of kimchi and a carrot were asked. However recognition for meats, fishes and eggs were not different between two groups. Among milk and dairy foods the educated group showed high recognition both calories and weight of a piece of cheese than the other(p<0.05). The educated group showed better recognition for calories and weight of tea-spoon of butter, a tea spoon of oil and a tea-spoon of mayonaise, compared to the other group(p<0.01, p<0.05, p<0.05). Also the educated group showed better recognition for calories and weight of a packet of shrimp snack than the other group. The results of this study suggest that nutrition education improved the recognition of calories and weights of foods in study subjects. Also, the number of foods recognized for their calories and weights was higher among subjects who received nutrition education. These results will influence the choice the food by adolescents. Also the nutrition education are thought to be more effective by using photographs or food models, not just by lectures on theories.

Until recently, colorectal polyps were classified predominantly as hyperplastic or adenomatous. While adenomatous polyps are well-characterized precursor lesions of adenocarcinomas, hyperplastic polyps have been considered as benign lesion. However, some hyperplastic polyps with serrated morphology of the crypts have been recognized to have distinctive features and these polyps were termed ‘serrated adenomas’. Recent data show that sessile serrated adenomas (SSA) might be the precursors of serrated colonic cancers, underlining the necessity of identifying them. SSA is approximately 3% of all polyps, commonly appears as flat or sessile and yellowish due to mucus production. In the pathogenesis of SSA, progression to high grade dysplasia or early invasive carcinoma may be associated with serrated neoplasia pathway different from adenoma-carcinoma sequence. We report a case with a colon polyp diagnosed as sessile serrated adenoma with high grade dysplasia after endoscopic submucosal dissection.

We developed a luciferase gene imaging system using a retrovirus for monitoring mesenchymal stem cell distribution. Retrovirus expressing firefly luciferase was infected into rat mesenchymal stem cells(rMSCs). rMSC-luc cells were excellent correlations between in vitro and in vivo bioluminescent activities and cell numbers. After systemic injections of cells in mice, luminescence activity was observed until six days, but was not detected in ischemic regions. After local injection with scaffold, luminescence activities were detected in injection sites over 3 weeks. This system could be a useful means for in vivo real time imaging of stem cell distributions, viability, and trafficking.

The pork meat been reported as one of the food occurring allergic reactions predominantly to korean. To identify the potential food allergens in pork meat, sera were collected from 25 allergic patients to the pork meat and 10 allergic patients not to pork meat as well as 5 normal subjects after skin prick test and open food challenge test. Crude extracts were prepared by blending raw pork meat in phosphate buffered saline (pH 7.0) and the heat treatment on crude extracts was carried to characterize sensibility of the allergens to heat. ELISA was performed to determine specfic IgE antibody levels of allergic patients to pork meat, and resulted in twofold higher mean value than that of tolerated patients. Extracted proteins from pork meat was separated with SDS-PAGE followed by immunoblotting using sera from pork sensitive patients and control subjects, respectively. The IgE binding response to pork meat by immunobots correlated with quentitative specfic IgE value of each person. Immunoblots showed four prominent IgE-binding bands (66, 60, 50, 44kDa) in crude extract, but two bands of those (60, 44kDa) were heat-labile. These results suggest that most prominent allergens from pork meat are four components(66, 60, 50, 44 kDa) in korean and the heat treatment on allergen is additional parameter to characterize allergen.

<P><B>Abstract</B></P><P><B>BACKGROUND:</B></P><P>The objectives of this study were to determine the proportions of major oncogenic alterations and to examine survival in genotype‐specific subsets of never‐smokers with nonsmall cell lung cancer (NSCLC).</P><P><B>METHODS:</B></P><P>The authors concurrently analyzed mutations in the epidermal growth factor receptor (<I>EGFR</I>) and v‐Ki‐<I>ras</I>2 Kirsten rat sarcoma viral oncogene homolog (<I>KRAS</I>) genes and investigated anaplastic lymphoma kinase (<I>ALK</I>) gene rearrangements in samples from 229 never‐smokers with NSCLC. <I>ALK</I> rearrangements were identified by fluorescent in situ hybridization and were confirmed by immunohistochemistry. Mutations in <I>EGFR</I> (exons 18 to 21) and <I>KRAS</I> (codons 12 and 13) were determined by direct sequencing.</P><P><B>RESULTS:</B></P><P>Of 229 tumors, the frequency of <I>EGFR</I> mutations, <I>ALK</I> rearrangements, <I>KRAS</I> mutations, and no mutations (wild type [WT]) in any of the 3 genes (<I>WT/WT/WT</I>) was 48%, 8.3%, 3.5%, and 40.2%, respectively. All genetic alterations were mutually exclusive. The median progression‐free survival after treatment with EGFR tyrosine kinase inhibitors (TKIs) was 12.8 months, 6.3 months, 2.1 months, and 1.6 months in patients with <I>EGFR</I> mutations, the <I>WT/WT/WT</I> genotype, <I>KRAS</I> mutations, and <I>ALK</I> rearrangements, respectively. In a Cox regression model, the adjusted hazard ratio for the risk of disease progression after treatment with EGFR TKIs was 0.59 (95% confidence interval [CI], 0.40‐0.87; <I>P</I> = .008) for patients with <I>EGFR</I> mutations, 4.58 (95% CI, 2.07‐10.15; <I>P</I> < .001) for patients with <I>ALK</I> rearrangements, and 4.23 (95% CI, 1.65‐10.8; <I>P</I> = .003) for patients with <I>KRAS</I> mutations. Overall survival also differed significantly among genotypes.</P><P><B>CONCLUSIONS:</B></P><P>To the authors' knowledge, this was the largest comprehensive and concurrent analysis to date of 3 major oncogenic alterations in a cohort of East Asian never‐smokers with NSCLC. Because survival outcomes differed among genotypes, and drugs that target specific alterations currently are available, genetic profiling to identify genotype‐specific subsets can lead to successful treatment with appropriate kinase inhibitors.

왕느릅나무(Ulmus macrocarpa)의 껍질을 말린 유근피는 오랫동안 부종, 감염 및 염증 제어의 목적으로 사용되어져 왔음에도 불구하고 잠재적 면역조절 효과에 관해서는 연구가 이루어진 바 없다. 본 연구에서는 전통 약용자원에서 새로운 면역기능 증가 신소재 발굴의 일환으로 유근피 열수 추출물의 면역 조절 효능을 RAW 264.7 대식세포 모델을 이용하여 조사하였다. 이를 위한 대식세포의 활성화 관련 지표로서 NO, TNF-α, IL-1β 및 IL-10의 생성량 변화를 조사하였다. 비록 유근피 추출물이 처리된 RAW 264.7 대식세포에서 IL-1β의 유의적인 유리는 관찰할 수 없었으나, NO, TNF-α 및 IL-10의 생성은 세포독성을 나타내지 않는 범위에서 유근피 추출물 처리 농도 의존적으로 증가되었으며, 이는 또한 iNOS, TNF-α 및 IL-10의 단백질 발현 증가와 연관되어 있었다. 아울러 유근피 추출물은 LPS에 의한 과도한 NO의 생성 억제능도 함유하고 있었으며, 유근피 추출물에 의한 대식세포의 활성화에는 NF-κB와 PI3K/Akt 및 MAPKs 등과 같은 면역 활성을 유도하는 신호전달계의 활성화가 연관되어 있음을 알 수 있었다. 따라서 본 연구의 결과는 유근피 추출물이 대식세포 활성화를 통한 면역 증강제로서의 개발 가능성이 매우 높음을 시사한다. The root bark of Ulmus macrocarpa has been used in traditional medicine for the treatment of various diseases such as edema, infection and inflammation. Nevertheless, the biological activities and underlying mechanisms of the immunomodulatory effects remain unclear. In this study, as part of our ongoing screening program to evaluate the immunomodulatory potential of new compounds from traditional medicinal resources, we investigated the effects of U. macrocarpa water extract (UME) on immune modulation in a murine RAW 264.7 macrophage model. As immune response parameters, the productions of as nitric oxide (NO) and cytokines such tumor necrotic factor (TNF)-α, interleukin (IL)-1β and IL-10 were evaluated. Although the release of IL-1β remained unchanged in UME-treated RAW 264.7 macrophages, the productions of NO, TNF-α and IL-10 were significantly increased, along with the increased expression of inducible NO synthase, TNF-α and IL-10 expression at concentrations with no cytotoxicity. UME treatment also induced the nuclear translocation of nuclear factor κB (NF-κB), and phosphorylation of Akt and mitogen-activated protein kinases (MAPKs) indicating that UME activated macrophages through the activation of NF-κB, phosphoinositide-3-kinase (PI3K)/Akt and MAPKs signaling pathways in RAW 264.7 macrophages. Furthermore, pre-treatment with UME significantly attenuated the production of NO, but not TNF-α, IL-1β and IL-10, in lipopolysaccharidestimulated RAW 264.7 cells suggesting that UME may be useful in preventing inflammatory diseases mediated by excessive production of NO. These findings suggest that the beneficial therapeutic effects of UME may be attributed partly to its ability to modulate immune functions in macrophages.
