The purpose of this study was to determine the effect of IPBC(3-lodo-2-propynylbutylcarbamate) on dandruff caused by the anthropophilic fungus Malassezia furfur. The effects of IPBC on dandruff were examined by evaluating (a) the MIC value of IPBC using broth dilution method; (b) the remnant antimicrobial activity of IPBC containing shampoo on skin disc; (c) the antidandruff efficacy of 1.0 % IPBC containing shampoo in double blind clinical trial. To investigate the remnant antimicrobial activity of IPBC against Malassezia furfur, guinea pig-skin disc was washed with antidandruff shampoo and then the diameter of inhibition zone per disc was measured. For clinical trial, thirty healthy volunteers, aged 25-35, participated in 4 week study. At 0, 2, 4 weeks, examinations of scaling, itching on scalp were carried out. The MIC(Minimun Inhibition Concentration) values of IPBC range from 0.10 to 1.00${\mu}g/ml$ and it seems that IPBC is more effective in the MIC values than zinc pyrithione, selenium disulphide, piroctone olamine and comparable to ketoconazole, climbazole. When the remnant antimicrobial activity of IPBC shampoo on skin disc was determined, 0.5% IPBC shampoo and 2.0% Ketoconazole shampoo resulted in similar antimicrobial effect. In addition, 1.0%, 2.0% IPBC shampoo was more effective than 2.0% ketoconazole shampoo. After two and four-weeks of 1.0% IPBC shampoo treatment, there was significant reduction of scaling, itching in test group compared to control group. On the basis of these results, it can be concluded that 1.0% IPBC is more effective than 2.0% Ketoconazole in reducing dandruff. It seems that strong capacity of drug binding to the stratum corneum plays a role in its antidandruff effect since adsorption of active ingredients on scalp is very important factor in reducing dandruff.

The purpose of this study was to determine the effect of IPBC(3-lodo-2-propynylbutyl carbamate) on dandruff caused by the anthropophilic fungus Maiassezia furfur. The effects of IPBC on dandruff were examined by evaluating (a) the MIC value of IPBC using broth dilution method : (b) the remnant antimicrobial activity of IPBC containing shampoo on skin disc ; (c) the antidandruff efficacy of 1.0 % IPBC containing shampoo in double blind clinical trial. To investigate the remnant antimicrobial activity of IPBC against Maiassezia furfur, guinea pig-skin disc was washed with antidandruff shampoo and then the diameter of inhibition zone per disc was measured.

The MIC(Minimun Inhibition Concentration) values of IPBC range from 0.10 to 1.00$\mu$ g/ml and it seems that IPBC is more effective in the MIC values than zinc pyrithione, selenium disulphide, piroctone olamine and comparable to ketoconazole, climbazole. When the rimnant antimicrobial activity of IPBC shampoo on skin disc was determined, 0.5% IPBC shampoo and 2.0% Ketoconazole shampoo resulted in similar antimicrobial effect. In addition, 1.0%,2.0% IPBC shampoo was more effective than 2.0% ketoconazole shampoo.

각종 약용 식물과 허브의 물 추출물을 제조하여 비듬균에 대한 항균활성을 조사한 결과 구절초(Chrysanthemum zawadskii)의 물 추출물이 7 mm의 생육저해환을 보여 가장 높은 항균활성을 보였다. 이 항균물질은 구절초 분말을 1:20으로 물에 현탁시킨 후 $50^{\circ}C$에서 6시간 진탕시켰을 때 가장 많이 추출되었고, 이 항균물질을 Diaion HP 20으로 크로마토그라피를 실시하여 부분 정제한 결과 정제물질은 물과 에탄올에 비교적 잘 녹았고 pH 3.0에서 9.0까지 안정하였다. 또한 구절초 물 추출물을 30% 첨가하여 제조한 시제품이 가장 항균활성이 우수하였고 첨가 농도가 높아질수록 굴절률은 비슷하였으나 pH와 점도는 오히려 낮아지는 경향을 보였다.
