  • Trichophyton(T.) tonsurans has been identified for the first time in Korea in 1995 and has been increasing in number of reported in wrestlers, in judo players, and in korean - style wrestlers. Author tried mycological studies with T. tonsurans is isolated in Daegu Korea. The results are as follows: All 16 strains of T. tonsurans tested for nutritional requirement, showed strongly stimulated growth by thiamine, mild to moderate growth on casamino acid agar, poor growth on ammonium nitrates base agar. All 16 strains of T. tonsurans tested showed positive results for hair perforation and urease test. Gross findings of T. tonsurans showed that fine granular surface with light yellow hue or white color and mahogany brown color on the reverse side. Microscopic findings showed that septated hyphae, chlamydoconidia and microcondia. Microconidia were characteristic in their arrangerment and shape : round or oval shaped microconidia laterally to hyphae, some were match - head like terminal swelling.

  • 저자는 우리나라에서 아직 보고되어 있지 않지만 앞으로 유입될 가능성이 있는 T. tonsurans에 대하여 경험을 넓히고자 미국에서 환자에서 분리한 T. tonsurans에 대상으로 여러가지 진균학적 검사를 실시하여 다음과 같은 결과를 얻었다. 1. 육안적으로 표면은 편평하고 무두질한 양가죽 양상으로 미세한 과립이 얇게 덮혀있고 연한 회색 또는 연한 황색을 나타내었으며 중앙에는 굴곡이 있고 뒷면은 마호가니 갈색을 나타내었다. urease test에서 균주에 따라 다양한 색깔을 나타내었다. 2. 현미경 소견에서 격벽이 있는 균사를 비롯하여 대분생자, 소분생자, spiral hyphae, 후막포자가 발견되었으며 소분생자의 배열과 모양이 특징적으로 균사를 중심으로 양옆으로 배열되어 길고 그 끝이 성냥 끝처럼 부풀어 있었다. 3. 모발천공검사에서 19주중 16주에서 양성소견을 보였다.

  • In this study, the author observed the fungal characteristics of T. verrucosum which is commonly known as the cattle ringworm fungus in the farms of Hoengseong, Gangwon-do. After isolating 20 strains of T. verrucosum from cattle, they were cultured on SDA, PDA media and the fungal characteristics were concluded through visual observation of the colonies, microscopic findings, hair perforation test and urease test. The size of the colonies cultured on SDA media at 37 C was on an average 5 mm at 1 week, 33 mm at 2 weeks, 42 mm at 3 weeks and 58 mm after 4 weeks. Observing the characteristics of the colonies, 17 strains of T. album showing central bold radial folds, 2 strains of T. ochraceum having l throughout the colonies and 1 strain of T. discoides with rapid growth rate and gray-white cotton patterns were found. On microscopic observations of the cultured colonies on SDA, PDA media, macroconidia and microconidia were not found in T. verrucosum and hyphae and chlamydospore were only seen in T. album types. Out of 20 strains of T. verrucosum, hair perforation test was positive on only 3 strains and urease test was positive on all of the 20 strains.

  • 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.

  • Introduction: Qūbā (Tinea Corporis) is a very common disease widely prevalent worldwide. 20 - 25 % individuals suffer for this stubborn disease. Unani System of Medicine offers its treatment. There are many pharmacopoeial formulations indicated for various types of dermatophytic infections. In this study clinical efficacy and safety of the topical Unani formulation Marham Kharish Jadeed (a compound drug in the dosage form of an ointment) was assessed and compared with a standard conventional medicine. Materials and methods: A clinical study was conducted on 60 participants of qūbā randomized into test and control groups (n=30 in each group). The participants were clinically diagnosed and confirmed by microscopy of skin scrapings. The efficacy of the Unani formulation was assessed in terms of TSS score and elimination of fungal elements from the skin lesions. The data collected were analyzed statistically. Results and discussion: The study showed that the Unani formulation had comparatively better efficacy clinically than conventional medicine Terbinafine hydrochloride 1% cream in terms of reduction of itching, erythema, scaling, peripheral raised margins of the lesion comparing to baseline. In this study, 27 participants in test group and 18 participants in control group were completely cured (≥75% reduction in TSS Score with Mycological Cure) after 4 weeks of treatment. The efficacy of the Unani formulation was found significant statistically. The individual drugs of the formulations having analgesic (Musakkin), blood purifier (Muṣaffi-i-Dam), demulcent (Mulaṭṭif), antifungal (Qātil-i-fafūndῑ), detergent (Jālῑ), refrigerant (Mubarrid) and antiseptic (Dāfi'-i-'Ufūnat) properties might be responsible for the efficacy of Unani formulation. Conclusion: The findings of the study suggested that the Unani formulation was found effective and safe in the management of qūbā. No local and systemic adverse effect was reported during the study.

  • 장성지역 잔디 재배지에서 총생 증상의 들잔디가 발생하였다. 총생 증상의 들잔디는 작고 다발형태로 유의한 형태적인 변화를 보였고, 병징은 여러 개의 잎이 짧은 포복경 마디에 무더기로 발생되어 빗자루처럼 총생 형태를 보였으며, 총생 형태의 잔디는 잎이 황화되면서 연녹색이나 노란색을 띄었다. 총생 증상을 보이는 들잔디는 건전한 들잔디에 비해 포복경 1개 마디당 약 5.8배 이상의 잎이 발생하였다. 또한 과도한 지상부 생육으로 인해 포복경과 지하부 생장이 저조하였다. 총생 병징의 들잔디를 채집하여 병원균을 배양한 후 관찰한 결과 포자낭의 모양은 레몬모양이었으며, 포자낭 축의 끝이 뾰족하게 튀어나와 있었고, 크기는 $60{\sim}96{\times}42{\sim}51{\mu}m$로 관찰되었다. 이는 Sclerophthora macrospora 병원균이 형성하는 포자낭의 균학적 특징과 유사하였고, 봄과 가을에 병징을 확인할 수 있었다. 따라서 본 연구를 통하여 국내 잔디 재배지 총생 증상에 대한 기초적인 자료를 제시하고자 한다.
