A Study of Antifungal Activity with Polygonum aviculare Linne

편축 추출물(抽出物)의 항진균작용(抗眞菌作用)에 관한 연구(硏究)

This study was undertaken to investigate the activity or the water extract of Polygonum aviculare Linne in vitro. Some of the purely isolated strains or dermatophytes were inoculated on Sabouraud's dextrose agar medium containing different concentrations of the Polygonum extracts and their growth was observed for about two weeks at room temperature. Then we measured the sizes of fungal colony grown in various conditions and compared them with those of Sabouraud's medium as control to determine fungistatic effectiveness of the extract. For additional study, slide cultures on Sabouraud's dextrose medium and Sabouraud's media containing 3ml/10ml extract were performed with Epidermophyton floccosum to observe the growth of hyphae, sporulation and other mycological findings. 1. The growth of Epidermo-phyton floccosum was completely inhibited in the media containing 3ml/l0ml Polygonum extract. 2. Trichophyton rubrum, Trichophyton mentagrophytes and microsporum canis were completely inhibited in several strains of each specimen and a moderate inhibitory effect was observed in all of another strains in the media containing the 3ml/10ml extract. 3. In the slide culture of Epidormophyton floccosum the hypha was thin and more desiccated. The characteristic macroco-nidia formation was not observed on the media containing 3ml/10ml Polygonum extract as compared with those findings of Sabouraud's dextrose control medium.

마디풀 전초(全草)의 건조물인 편축의 열수전탕(熱水煎湯)의 여과액으로 증발 농축시킨 추출액을 만들어 대조인 Sabouraud's dextrose arar 배지에 매지 10ml當 편축 추출액 0.5,1,2 및 3ml를 각각 혼합한 배지로서 T. rubrum, T. mentagrophytes, E. floccccosum 및 M. canis 등 4균종을 각각 3종씩 배양하여 그 발육상태를 관찰하므로서 진균발육억제작용의 유무를 검색하여 다음과 같은 성적을 얻었다. 1. E. floccosum은 편축추출물 3ml 혼합의 평판배지 사면배지 및 현적배양에서 거의 완전히 현지한 균발육억제작용을 인정할 수 있었다. 2. T. menagrophytes, T. rubum 및 M. cains에 대해서는 부분적으로 현저한 억제자용과 발육균태(菌苔)의 크기로 보아 반이불(半以不)의 크기로 발육이 억제되는 증정도의 억제효과를 인정하였다.
