The present study was carried out to investigate the antibacterial activity against Staphylococcus aureus with antibiotic-resistance in vitro and the skin irritation in rabbits with surfactin produced by Bacillus subtilus Complex BC1212. The antibacterial activities of selected antimicrobial agents (surfactin, amoxacillin, colistin, norfloxacin and streptomycin) were evaluated by using the broth microdilution method. As the results, the minimum inhibitory concentration (MIC) of the surfactin was less than 15.6 ㎍/ml. In the skin irritation test, two out of 4 rabbits showed very slight edema at 24 h after the administration of surfactin, and then recovered at 72 h. The change of body weight was normal during the skin irritation test. The primary irritation index in accordance with the Draize evaluation of topical reaction was calculated to be '0.125', which meant not irritating. Based on these results, it could be concluded that the test agent, surfactin, was a non-irritant. We could also think that the surfactin may be useful for the treatment of S. aureus infections such as bovine mastitis.

마의 껍질을 제거하거나 상처가 생겼을 때 발생하는 갈변현상을 억제할 수 있는 방법을 개발코자 실험을 수행한 결과는 다음과 같다. 1. 마는 박피후 시간이 경과할수록 갈변지수가 높아지는 경향를 보여 박피 후 15시간에 갈변지수가 장마는 38까지 증가한 반면 단마는 13이 었으며 이로서 장마가 단마보다 갈변이 빠르게 진행됨을 알 수 있었다. 2. 장마의 경우 NaCl 2M 처리시 갈변억제율이 48시간에 48%로 가장 높았고 특히 $80^{\circ}C$ 온탕처리의 경우 24시간까지 높은 억제율을 보였으나 이후 급격히 감소하는 경향을 보였다. 3. NaCl 1M 처리시 단마의 갈변은 43% 정도 억제 되었으나 NaCl 0.5M과 $70^{\circ}C$ 온탕처리는 비슷한 억제현상을 보였다. 그러나 $60^{\circ}C$ 온탕처리는 무처리보다 더 높은 갈변지수를 나타내었다.

This study was carried out to know the effects of Gwanjul9-bang (hereinafter reffered to GJ9) on the inhibition of arthritis induced by collagen on DBA/1J mouse. For this purpose, GJ9 was orally administered to mouse with arthritis induced by collagen II. Cytotoxicity, hepatotoxicity, arthritis index, value of immunocyte in draining lymph node and paw joint, rheumatoid factor (IgG, IgM) in serum were measured in vivo. The cytotoxicity against hFCs was not measured in any concentration. The hepatotoxicity was low in GJ9 treated group compared with MTX group. The arthritis index was decreased significantly. In total cell counts of DLN and paw joint, the cells in DLN increased significantly while there was significantly decrease in paw joint. In lymph nodes, $CD19^+$, $CD3^+$, $CD4^+$, $CD3^+CD69^+$, $CD8^+$, $CD4^+CD25^+$, $CD3^+CD49b^+$, $CD4^+CD44^+$, $CD3^+CD8^+$ cells increased significantly, $B220^+CD23^+$cells decreased significantly. In joints, $CD3^+$, $CD4^+$, $CD4^+CD25^+$, $CD11b^+Gr-1^+$ cells decreased significantly. The levels of IgG and IgM was significantly decreased compared with control. Anti-collagen II in serum was significantly decreased compared with control. The degree of arthritis induced damage of joint of GJ9 group is slight compared with control group in histopathologic observation (Hematoxylin & Eosin, Masson's Trichrome). Comparison of the results for this study showed that GJ9 had immunomodulatory effects. So we expect that GJ9 should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

This study examined the efficacy of natural ingredient formulated herbal medicine as feed additives against coccidiosis in broiler chicken. Medicinal herbs used in this study were Artemisia annua, Pulsatilla chinensis, Clematis chinensis and Scutellaria baicalensis. Two week old chicks were administered with 1% ingredient formulated herbal medicine. Observations of the efficacy were confirmed by examining the lesion score, histopathological appearance of cecum, shedding of fecal oocyst and production index in farm. S. baicalensis of the most effective substance were analyzed by UPLC. The results are as follows; among various types of Chinese medicine, the most efficacious ingredient was found to be pure bicalein. The major index substance is bicalein and $13{\mu}g/ml$ per gram was found. Feeding of chickens with S. baicalensis induced the coccidiostat effect and reduced the fecal shedding of E. tenella oocyst by 14%. Experimental results on a farm, feed conversion ratio and weight gain and production rate in the group with natural ingredient formulated additives than in control group increased. The rate of weight gain (%) in each experimental group showed 108% and 126% increase while the mortality rate was 1.4% lower than the control group. The investigation showed that the most efficacious ingredient was found to be S. baicalensis among herbal medicine products for coccidiostats. However, as it was found in the farm experiment that pure S. baicalensis alone is economically unviable. The additives with cocktailed of efficacious ingredient are suggested to be implemented for effective protection against coccidiosis.

본 연구에서는 녹두 및 대두의 용매추출물을 제조하고 hepatoma 1c1c7 세포 및 대식세포인 RAW264.7 배양을 이용하여 항암 및 항염증 효과를 비교분석하였다. 녹두추출물은 대두추출물 보다 ethylacetate 및 ethanol 추출물에서 모두 유의적으로 높은 QR 유도활성과 NO 및 $PGE_2$의 생성 억제 효과를 보였으며 농도 의존적 효과를 나타냈다. C18 silica flash column chromatography를 이용하여 회수된 녹두에탄올 추출물의 7개 분획 중 소수성이 가장 강한 분획은 24 ${\mu}g$/mL의 CD value와 783 ${\mu}g$/mL의 $IC_{50}$를 보였다. 현재 다수의 염증 억제물질의 작용기전이 prostaglandin 합성 억제이며 이는 COX-2의 생성 및 활성저해에 의한 것임을 근거로 할 때 녹두의 ethanol 추출물은 항염증 및 암 발생 예방 성분을 분리하기 위한 중요한 식품 자원으로 생각된다.
