This experimental study was performed to investigate the antifungal effects of mixture of Sophorac Subprostratae Radix, Aconti Radix, and Hibisci Syriaci Cortex by the three types of extraction in the dermatophytes such as Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum. The following results were obtained by using Minimum Inhibition Concentration(MIC) and Inhibition Zone. 1. MIC on Trichophyton mentagrophytes in Sample S-2, Sample S-3, and Sample-Y were 10${\mu}l$, respectively, showing the highest antifungal effect. 2. MIC on Epidermophyton floccosum in Sample S-2, Sample S-3, and Sample-Y were 10㎕ respectively, showing the highest antifungal effect. 3. MIC on Trichophyton rubrum in Sample S-3, Sample-Y were 10${\mu}l$ respectively, showing the highest antifungal effect. 4. The size of inhibition zone on Trichophyton mentagrophytes for Sample S-3 were 22.3mm in 10${\mu}l$, showing the highest antifungal effect. 5. The size of inhibition zone on Epidermophyton floccosum for Sample S-3 was 34.3mm in 10${\mu}l$, showing the highest antifungal effect. 6. The size of inhibition zone on Trichophyton rubrum for Sample-Y was 26.5mm in 10${\mu}l$, showing the highest antifungal effect. Whereas. in extractions, that of Sample S-3 was 12.5mm in 10${\mu}l$, showing the highest antifungal effect. 7. From the above results, Sample S-3 on Trichophyton mentagrophytes, Epidermophyton floccosum and Sample-Y on Trichophyton rubrum showed the highest antifungal effects. This results suggests that vinegar extraction excels other extraction method using water or ethanol to measure the antifungal effect on dermatophytes. In addition, the result shows that the extract of herbal medicines can be used to tinea pedis and if further study is performed, the use of the extract of herbal medicines will be valuable and beneficial in the clinical medicines.

Dermatophytes can invade in keratinized tissues and cause dermatophytosis [1] that rank among the most widespread and common infectious diseases world-wide. Although several systemically and topically administered drugs with activities against these fungi are available, still complete eradication of some of these infections, is difficult and relapses and remissions are often observed [2,3]. In addition, some people are allergic to many of the available drugs which add complications even more. Therefore, the search for novel, selective and more effective therapy is always required and it may help the clinicians to choose the correct treatment for their patients. Non-thermal plasmas primarily generate reactive species and recently have emerged as an efficient tool for medical applications including sterilization. In this study, we evaluated the ability of non-thermal dielectric barrier discharge (DBD) plasma for the inactivation of clinical isolates of Trichophyton genera, Trichophyton mentagrophytes (T. mentagrophytes) and Trichophyton rubrum (T. rubrum), which cause infections of nails and skin and, are two of the most frequently isolated dermatophytes [4]. Our results showed that DBD plasma has considerable time dependent inactivation potential on both T. mentagrophytes and T. rubrum in-vitro. Furthermore, the mechanisms for plasma based T. mentagrophytes and T. rubrum inactivation and planning for in-vivo future studies will be discussed.

The authors performed clinical and mycological studies on Tinea cruris of 842 outpatients who had visited the dermatology clinic of Seoul National University Hospital from 1975 to 1979. 1) The incidence of Tinea cruris was 4.4% in maximum and 3.0% in minimum of the total superficial mycotic diseases cases, so there are no remarkable changes of the yearly prevalence rate. 2) Tinea cruris was more frequent among males, and the male cases were 15.2 times higher than those of female cases. 3) By the monthly distribution, Tinea cruris shows most high in summer season (June, July and August). 4) The age distribution group for Tinea cruris varied from the first to the eighth decade, but most of them were in their third decade. 5) Concurrent infection of Tinea cruris with other types of dermatophytoses(Tinea) was noted in 19.0% of the cases. Patients with Tinea cruris and Tinea pedis were most highly observed in 51.3%, and on next. Tinea cruris and Tinea corporis 25.6% in all of the concurrent infection cases. 6) The strains were identified by culture on ordinary Sabouraud's glucose agar media and abtained three species and 99 strains. a) Trichophyton rubrum was most common causative organism of Tinea cruris. Trichophyton rubrum was isolated 64 strains (64.6%). b) Trichophyton mentagrophytes was isolated 27 stains (27.3%) and Epidermophyton floccosum was 8 strains (8.1%).

본 실험에서는 3종의 한국산 겨우살이 메탄올 추출물을 유기용매 분획과 컬럼크로마토그래피를 이용한 분획을 실시한 후, Tyromyces palustris, Endothia nischkei 그리고 Trichophyton rubrum에 대한 항균활성을 평가하여 겨우살이 추출물의 항균활성 자료로 활용하고자 하였다. 그 결과 모든 겨우살이 추출물은 갈색 불후균에 대한 활성은 매우 낮게 나타났다. 그러나 Viscum albumvar. coloratum 추출물중 부탄올 분획은 황색줄기 마름 병원균의 성장을 억제하는 것으로 나타났으며, 이 겨우살이의 EtOAC 분획은 족부백선균에 대하여 높은 포자 발아 억제효과를 나타내었다. 시험된 3종의 한국산 경우살이류 중 V. album var. Coloratum은 병원균에 대하여 황균활성 성분을 함유할 가능성이 가장 높을 것으로 제시되었다.

Spherical silver nanoparticles (nano-Ag) were synthesized and their antifungal effects on fungal pathogens of the skin were investigated. Nano-Ag showed potent activity against clinical isolates and ATCC strains of Trichophyton mentagrophytes and Candida species ($IC_{80}$, 1-7${\mu}g/ml$). The activity of nano-Ag was comparable to that of amphotericin B, but superior to that of fluconazole (amphotericin B $IC_{80}$, 1-5${\mu}g/ml$; fluconazole $IC_{80}$, 10-30${\mu}g/ml$). Additionally, we investigated their effects on the dimorphism of Candida albicans. The results showed nano-Ag exerted activity on the mycelia. Thus, the present study indicates nano-Ag may have considerable antifungal activity, deserving further investigation for clinical applications.

The effect of Rhinacanthus nasutus leaf extract on the growth of dermatophytes had been investigated. In vitro the extract exhibited high activity against various species of dermatophytes (Trichophyton mentagrophytes var. mentagrophytes, T. mentagrophytes var. interdigitale, T. rubrum, Microsporum canis and M. gypseum). The minimal inhibitory concentration (MIC) values of the extract revealed that all the dermatophytes tested had MIC values of 13.6 mg/ml. The extract exhibited fungistatic activity at lower concentrations $({\leq}13.6\;mg/ml\;or\;below\;the\;MIC\;value)$ and fungicidal activity at higher concentrations $({\geq}13.6\;mg/ml$\;or\;above\;the\;MIC\;value)$. The results suggested that the extract acted on the cell wall of the dermatophytes which subsequently leading to the formation of cytopathological and membrane structural degeneration and finally leading to cell lysis and death.

The mattresses and dust in the bed rooms of nine dermatophytes infected patients and nine domestic animals were examined by the KOH method. Microsporum canis species and Trichophyton mentagrophytes were isolated from cats and rabbits, respectively. The sources of infection of three patients were the M. canis infected cats raised by them and the four other patient's sources of infection were not confirmed. The sites of infection of the nine patients were their heads and those of the domestic animals were their heads and bodies. M. canis species were isolated from the infection sites of three cats and specimens collected by hair brush from the nine domestic animals. T. mentagrophytes species were also isolated from the infection sites of two rabbits. The seven patients had mattresses and bed room dust contaminated with M. canis.
