In this paper, we implemented medicinal plant information system based on user requirement using Ajax technique which can retrieve data from the server asynchronously in the background without refresh webpage and jQuery which is a lightweight cross-browser javascript library. Also, we presented the source code handling the server response data used in the system and compared the features by the type of response data. This system shows the improvement of user interaction and response rates because of a simple response data from the server, client-side data processing and change of web page by manipulating the DOM tree and provides ease of use and convenient data access.

We analyzed the data on medicinal plants and related traditional knowledge in Korea and China using data analysis method. There are 108 families 214 genera 542 species, and 202 families 660 genera 1,261 species were found in Korea and China respectively. Total of 86 families (79.6%) and 130 genera (60.7%) were in common both countries. More than one information were recorded in many species, however, there was only one information from some species (32.7% of genera in Korea, and 58.8% of genera in China). The most frequent appeared plant family was Compositae (Asteraceae) in both countries (8.4% in Korea and 10.7% in China) and followed by Rosecease and Leguminocae (Fabaceae). Plant parts were classified 11 parts and roots were mostly used in Korea and whole plants in China. Usages were described in different terms of ailments or symptoms. There are 120 usage in Korea and 230 in China. Plant uses for the ailment or symptoms are pain, digestive system disorder, cold and etc. in Korea. In China, plants were mostly used for clear heat, digestive system disorder, cough and etc. Relation between the plant and ailment(symptom) of the top 10 plants in Korea and China was different although from same plant family. We also analyzed the relations between plant species and part used, and plants parts and ailment(symptom). With the data analysis method, we were able to collect the medicinal plant resources data and found the differences in plant resources, usage, and plant part for use. The result provide important information of the plant resources and related traditional knowledge of Korea for use of plant resources in industry and facilitate to plan a strategy to cope with Nagoya Protocol in the future.

Identification of natural compounds that can prevent the development of obesity in vivo is time consuming and expensive. We have used in vitro systems derived from pig adipose tissue to screen simple aqueous or ethanolic extracts of Korean medicinal herbs (KMH) for their anti-adipogenic potential. A total of 183 extracts were tested for their actions in lipogenesis of pig adipose tissue and differentiation of pig preadipocytes. Ethanol extracts were prepared from 72 and aqueous extracts were prepared from 111 medicinal herbs. Both an ethanolic and an aqueous extract were prepared from 65 of these. Thirteen extracts substantially altered rates of lipogenesis in vitro. The effects of KMH on lipogenesis of pig adipose tissue are as follows. Elevens reduced lipogenesis to rates that were more than 40% lower than control and four of these reduced rates of lipogenesis by more than 70%. The most potent anti-lipogenic extracts were those obtained in ethanol from Iridaceae and from Sophora flavescens AIT as well as both the aqueous and ethanolic extracts from Lysimachia vulgaris L. Two extracts, those prepared in water from Caesalpiniae lignum and from Phellodendri cortex, were found to promote rates of lipogenesis in vitro. The effects of KMH on differentiation of pig preadoipocytes are as follows. Twentyeight extracts altered the rates of differentiation of cultured porcine preadipocytes. Sixteen increased and twelve reduced the rates of differentiation of preadipocytes. Extracts prepared in ethanol from Moutan radicis cortex and from Ostericum koreanum and those prepared in water from Angelicae gigantis radix, from Inula henenium L and from Magnolia flos doubled the rate of differentiation of cultured porcine preadipocytes. Ten extracts reduced the in vitro rate of differentiation of porcine preadipocytes by more than 35%. These were the ethanolic extracts from Glycyrrizae radix, Nepetae spica and from Polygala myrtifolia and the aqueous extracts from Amaranthaceae, Asparagus cochinchinesis, Atractylodis rhizoma alba, Citrus junos TANAKA, Cyperus rotundus, Epimedium grandiflorum and from Moutan radicis cortex. Only the ethanolic extract from Polygala myrtifolia was able to both reduce lipogenesis in adipose tissue slices and retard differentiation of cultured preadipocytes. The results of our study will provide meaningful information to identify medicinal herbs which would reduce fat deposition in livestocks and humans.

비무장지대(DMZ)는 군사적 활동 외에 일반인에 의한 접근이 엄격히 통제되어 자연적으로 생물들이 보호되어 왔으며, 한반도의 거대한 동 서 생태축으로서 그 중요성이 매우 높다. 본 연구는 경기도 연천군지역의 비무장지대 및 민통선지역에 분포하는 자원식물의 현황을 파악하고 희귀식물, 한국특산식물 등 주요 유용자원식물의 보전과 관리에 기초자료를 제공하고자 실시하였다. 연구대상지에 분포하는 자원식물은 74과 168속 192종 4아종 26변종 5품종으로 총 227분류군으로 우리나라에 분포하는 관속식물 4,881(국립수목원, 2007)분류군의 4.66%로 나타났다. 각 과별 구성종의 출현비율을 살펴보면 국화과 36분류군으로 가장 다양하게 출현하였다. 연구대상지내에 분포하는 희귀식물은 쥐방울덩굴(Aristolochia contorta Bunge)로 1분류군이 확인되었으며, 한국특산식물은 키버들(Salix koriyanagi Kimura), 병꽃나무(Weigela subsessilis (Nakai) L.H.Bailey), 은사시나무(Populus tomentiglandulosa T. B. Lee)로 3분류군, 귀화식물은 단풍잎돼지풀(Ambrosia trifida L.), 족제비싸리(Amorpha fruticosa L.), 아까시나무(Robinia pseudoacacia L.) 등 등 17분류군으로 나타났다. 연구결과 전체적으로 다양한 식물종이 확인되지는 않았으며, 일부 구간에는 가시박(Sicyos angulatus L.), 돼지풀(Ambrosia artemisiifolia L.), 단풍잎돼지풀(Ambrosia trifida L.) 등 생태계교란 야생식물이 폭넓게 분포하고 있는 것을 확인할 수 있었다.

The study was conducted to investigate the effect of dietary supplementation of Lactobacillus, medicinal plants extract, and essential oil on laying performance, cecal microflora, relative organic weight, leucocyte profiles in laying hens against Salmonella gallinarum. A total of 100 Hy-Line Brown laying hens of 65 weeks of age were assigned into 5 dietary treatments supplemented with no antibiotic (negative control), antibiotic (positive control), Lactobacillus 0.1% (LB), medicinal plants extract 100 ppm (MPE), herb extract 100 ppm (EO). After 7 days of treatment, the 20 hens in each treatment group were divided into challenge group (n=10) and non-challenge group (n=10) for oral administration of Salmonella gallinarums, and were maintained in the same dietary treatments for two additional weeks. Laying hens were selected 20 by each treatment, splitting up into oral Salmonella group and nontreated group. The feeding trial lasted for one weeks and Salmonella gallinarum was orally administered for two weeks. Egg production, egg weight, egg mass, and feed conversion ratio were calculated and cecal microflora, relative organ, and blood were collected at the end of experiment. Compared with the control, laying hens fed Lactobacillus, medical plant extract, and essential oil were not observed to change of laying performance. Salmonella count increased significantly when Salmonella gallinarum was orally administered (P<0.05) but coliform bacteria and Lactobacillus counts were not affected. The relative organs weight was not different in hens with oral administration of Salmonella gallinarum and also in hens fed Lactobacillus, medical plant extract, and essential oil. H/L ratio was not significantly different, but total leucocyte level was somewhat increased in the treatment with oral administration of Salmonella gallinarum and more leucocyte increased in laying hens fed Lactobacillus, medical plant extract, and essential oil than control.
