We developed the educational purpose mobile application, named "Wild Flowers of Bukhansan National Park (version 1.0)", aiming for easy identification of wild flowers for students and visitors in the park. When visitors find a flower or part of plant in the park, visitors can search for its name utilizing the pictures and characters provided in their own smartphone mobile devices or tablet PCs. The application provides pictures of wild flowers in the park and character-based searching system based on 12 diagnostic features (e.g., growth form, leaf arrangement, flower symmetry, petal color, petal number, sepal number, etc). We adopted the complete floristic survey of Chung and Lee (1962) and added species that we confirmed their distribution in the park during the development of this application. In summary, number of vascular plants in this park was estimated to be 428 taxa including 100 families, 280 genera, 327 species, 1 subspecies, 50 varieties, and 5 formas. We provided a total of 588 pictures representing 358 taxa and each taxon includes multiple pictures in many cases. Included identification quizzes can be an efficient educational tool as well as fun activity for students and visitors who are learning plant species in Korea. Our next step will include GPS function in the application for indicating visitor's location and for providing previously reported sites of the species that we interested in the map of the park. The future application which includes GPS function will be a valuable tool for the monitoring of rare plants, plant researches related to the climate changes, etc. We currently provide Korean iPhone version only, and English version and both of android versions will be serviced soon.

본 연구는 인삼의 가공방법을 개발하고 제품을 다양화하기 위한 기초 자료를 확립하고자, 우리나라의 전통주인 약주로 증자한 후 홍삼의 일반성분과 ginsenoside의 함량을 분석하고 갈색도 및 탁도의 변화를 알아보았다. 또한 항암효과를 검증하였던바 그 결과를 보고하고자 한다. 1. 백삼과 홍삼, 증자 횟수별 인삼의 갈색 변화를 보기 위해서 각 인삼의 60% 에탄올추출물의 갈변의 측정 결과 갈변의 전구물질과 중간생성물 및 fufural, 갈색계의 색소, 탁도 모두 증자횟수가 증가 할수록 값이 증가하였다. 그리고 백삼, 홍삼 A1는 3가지 항목에서 모두 비슷한 경향을 보였으며, 상대적으로 A3에서 높은 값을 보였다. 2. HPLC상으로 total ginsenoside의 함량을 측정한 결과 백삼 28.20mg/g, 홍삼 421.10mg/g이고 A1~A9에서는 46.10~76.80mg/g으로 홍삼과 백삼보다 증자 횟수가 증가 할 수록 total ginsenosied 함량이 증가하였다. 3. HPLC상에서 분석한 증자 횟수별 인삼의 ginsenosides(G-Rb₁, -Rb₂, -Rc, -Rd, -Re, -Rf, -Rg₁, -Rg₂, -Rg₃)의 함량변화는 G-Rc, -Rd, -Re는 1회 증자한 A1에서 함량이 증가 하다가 증자 횟수가 증가 할수록 다시 함량이 감소하였으며, G-Rg₂, -Rg₃는 증자 횟수와 비례하여 함량이 증가하는 경향을 보였다. 4. 인체유래 간암세포(Hep3B)에서의 항암효과 검증실험에서는 물, 60%에탄올 추출물을 각각 1000ppm, 2500ppm, 5000ppm으로 처리 한 후 세포 증식 억제율을 확인하였다. 백삼은 모든 처리군에서 미미한 증식억제 효과가 있었으나, 홍삼은 60%에탄올 추출물 5000ppm에서 54.52%, A9에서는 96.28%의 현저한 세포증식억제 효과가 있었다. A9가 Hep3B에 대해서 백삼과 홍삼보다 세포 증식 억제율이 더 높은 것을 확인 할 수 있었다. 이상의 결과로 볼 때 약주를 이용해서 증자한 홍삼이 백삼이나 일반홍삼보다 총 사포닌, 진세노사이드의 함량이 증가하였고, 기능과 효능이 증강된 것으로 확인되어 우수함이 입증되었다. 또한, 홍삼정과, 절편정과 등 제품의 다양화와 품질개선에 기여할 것으로 기대된다. 향후 증자 방법, 압력, 온도, 및 약주 등의 제조 조건에 따른 지속적인 연구가 요청된다. This study takes place to establish basic data to develop various ginseng-processing methods and products. It analyzed components and quantity of ginsenoside in red ginseng after brewing with the traditional medicinal wine as well as the brownness and impurity level changes, and verified anti-oxidization and anti-cancer effects. The following is the founding of these analyses. To examine the changes in the brownness of white and red ginseng, premonitory materials of 60% ethanol extracts were examined As the result of these examinations, all of the values of examined matters premonitory materials, mid products, Fufural, coloring matters and impurity level were increased as the brewing continued. And the brownness level for white and red ginseng was similar in Al and the values were relatively high in A3. The total Ginsenoside on HPLC was 28.20㎎/g for white ginseng and 42.10㎎/g for red ginseng. The quantity of total Ginsenoside was increased as the brewing continued as 46.10∼76.80㎎/g was shown in A1∼A9. To see the quantity changes of Ginsenosides(G-Rbi, -Rte, -Re, -Rd, -Re, -Rf, -Rg₁, -Rg₂, -Rg₃) contained in ginseng on HPLC, the quantity of G-Rc, -Rd, -Re were increased in Al the first brewing and decreased as the brewing continued. The quantity of G-Rg2, -Rg3 was increased proportionate to the number of times for brewing. In an anti-cancer test in liver cancer cells(Hep3B) extracted from human body, each of water and 60% ethanol extracts were processed with 1000ppm, 2500ppm, and 5000ppm and checked the multiplication restrain rate. All of the processing groups in white ginseng have minimum multiplication restrain rates, but red ginseng has 54.52% at 60% ethanol extract 5000ppm. At A9, 96.28%) of cell multiplication restrain effects were shown. Comparing Hep3B to A9, white ginseng has higher restrain effects than red ginseng. As seen in the above results, the reinforced red ginseng using the medicinal wine has higher total saponin and ginsenosides, as well as with increased functions and effects leading the superiority. And it is possible to use Red Ginseng Jung Kwa; Jung Kwas with flower pattern imprinted, and expect to increase the opportunities to use the extracts. Later, when brewing the pressure, temperature, and medicinal wine can be examined to continuous studies.

Abstract – Aberrant crypt foci (ACF) are early imorphological changes observed in rodents after administration of colon-specific carcinogen such as azoxymethane (AOM). ACF are considered to be putative preneoplastic lesions and are widely used as a surrogate biomarker to rapidly evaluate chemopreventive potential of compounds. The size of colorectal cancer was evaluated after administration of three anticancer drugs, 1 parent drug and 2 prodrugs. The body weights of mice were measured daily and considered as a surrogate for evaluation of general wellbeing. Colons were removed, cut along the longitudinal axis and flushed with phosphate-buffered saline. Each colon was cut into three equal lengths and fixed flat between filter papers. The fixed colon sections were stained with methylene blue. The number of ACF per colon, the number of aberrant crypts observed in each focus and the location of each focus were recorded. After single administration of AOM and multiple doses of anticancer drugs, no significant changes in the body weights of the mice was observed which was recorded for 52 days. However, an expected ACF was not observed in any treated groups. These findings suggest the induction of ACF in mice requires the promotion by dextran sulfate sodium as well as the initiation by AOM.

This study used P.acnes, which causes acnes, and P.aerugmosa, Pseudomonase aeruginosa, as the antigen, and then blue egg-laying chickens, arakana mixed, to be immune to this antigen. After that, we measured the productivity of special antibody (IgY), characteristics of special antibody, antigenicity & molecular weight and antibiosis. The results were are Followed. We had three times of immune injection of each antigen (P.acnes, P.aeruginosa, P.acnes+P.aeruginosa). The second injection was after 2 weeks of the first shots, and the second injection was after 5 weeks of the second shots. The special antibody (IgY) was produced after I week of vaccine shot in lymph and after 2 weeks in yolk. The value steadily increased and reached its highest degree in 4 weeks. Especially, the mixed injection of two antigens showed much higher increase in antibodies than single antigen injection group. The fraction of special antibody that passed the DEAE-Sephacel column showed that the antibodies of P.acnes was located in 210∼325㎖, P.aeruginosa was in 230∼370㎖ and P.acnes+P.aeruginosa was located in 240∼360㎖. We measured the refine lgY with SDS-PAGE, and we observed similarities in three antibodies. They showed heavy chain in 66kDa and light chain m 29kDa. We analyzed the antigenicity for individual germ by western blotting. P.acnes showed one near 40kDa band. P.aeruginosa showed 2 near 55kDa, 2 in 45kDa, 1 in 36kD, 1 in 29kDa and 1 in 20kDa. As for P.acnes+P.aeruginos, it showed 1 in 45kDa, 1 in 38kDa, 29kDa and 2 antigenicity in 20kDa band. We measured the heat stability in each special antibody.

( Ye Ji Jang ),( Bok Won Park ),( Jun Yeong Park ),( Eun Byul Cho ),( Eun Joo Park ),( Kwang Ho Kim ),( Kwang Joong Kim ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2

Background: It is challenging for clinicians to distinguish between Pityrosporum folliculitis (P. folliculitis) and acneiform eruption based on clinical and histological features. The studies of histopathologic differences between P. folliculitis and acneiform eruption have been poorly described. Objectives: We sought to distinguish between P. folliculitis and acneiform eruption on a clinicopathologic basis. Methods: We retrospectively analyzed the histology of hematoxylin-eosin-stained sections obtained from 52 patients diagnosed with P. folliculitis and acneiform eruption. Results: The presence of fungal spores in follicular lumen was more consistent with a diagnosis of P. folliculitis. Intrafollicular inflammation, irregular pattern of keratin plugging, nuclear dust in follicular lumen favored a diagnosis of acneiform eruption. There was no difference in perifollicular inflammatory cell infiltration between P. folliculitis and acneiform eruption. Conclusion: Our study demonstrated that a significant difference exists in the presence of necrotic keratinocytes in the follicular wall, intrafollicular constituents, and inflammatory cell infiltration between P. folliculitis and acneiform eruption. And it is thought that the necrotic keratinocytes have a key role on these differences. These findings might be helpful in understanding pathogenesis and differential diagnosis of P. folliculitis and acneiform eruption.
