Objectives : The authors conducted randomized, Double-blinded, and placebo-controlled parallel-group clinical experiment study to evaluate efficacy of fermented soybean(Bio-Peptone)cream in pruritus. Methods : The research had been conducted for 4 months from the date of IRB approval(May 26 in 2017) to Sept 2017. The experiment started by randomly distributing 25 subjects with pruritus into experimental group and control group, respectively. The experimental group applied fermented soybean(Bio-Peptone)cream twice a day, in the morning and evening, for one week on itchy area. The effect of the product was evaluated by comparing the PSS(Patient subjective score), moisture level by measuring skin moisture content(Corneometer) and transepidermal water loss(Tewameter), and the Korean version of Skindex-29(index of quality of life improvement) before applying the cream, after applying the cream for one week and after stop applying the cream for one week. The control group conducted identical experiment with the experimental group, except the control group applied placebo instead of the fermented soybean(Bio-Peptone)cream. Results : Pruritus, criterion of the first validation testing, indicates fermented soybean(Bio-Peptone)cream tend to reduce pruritus compare to placebo, although the result is not statistically noticeable. Significant difference in reduction of prutitus, the second validation test was not discovered in both groups. Corneometer and life quality tend to be improved with soy cream than placebo, but not statistically effective and both groups did not show any difference in terms of Tewameter measurement. Conclusions : The result of clinical experiment didn't prove that the fermented soybean(Bio-Peptone)cream is more effective in reducing pruritus than placebo, statistically. The clinical use of soybean product for pruritus requires further studies to be verified.

Objectives : The aim of this study is to examine the effect of external application containing herbal extracts (Betula platyphyllae Cortex, Viticis Fructus, Agrimoniae herba) to patients with atopic dermatitis. Methods : Twenty patients (experiment group) were treated with the external application containing herbal extracts (Betula platyphyllae Cortex, Viticis Fructus, Agrimoniae herba) and other twenty patients (control group) were treated with normal external application that doesn't contain herbal extracts for 2weeks. We observed comparisons between experiment and control group after 1week, 2weeks. Degrees of severity of atopic dermatitis were measured by SCORAD index (Scoring of Atopic Dermatitis Index). Statistical significance was achieved if the probability was less than 5% (p<0.05). Results : 1. After 1week of external application treatment, SCORAD Index in experiment group was significantly decreased comparing with control group, which is a marginally significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. 2. After 1week of external application treatment, Intensity Criteria (Erythema, Edema/papulation, Total) in experiment group was significantly decreased comparing with control group, which is a statistically significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. 3. After 1week and 2weeks of external application treatment, comparison of changes in Subjective Symptoms (Pruritus, Insomnia) indicated that the experiment group showed no statistically significant result. 4. After 1week of external application treatment, Total Quality of life through Skindex-29 in experiment group was significantly decreased comparing with control group, which is a marginally significant result between two groups. But after 2weeks the experiment group showed no statistically significant result. Conclusions : As a result of applying the external application containing herbal extracts to patients with atopic dermatitis and watching the progress, we can speculate that the external application containing herbal extracts has especially short-term therapeutical effects in mitigating the symptoms of Atopic Dermatitis. Thus, it is concluded and considered that the external application containing herbal extracts can be used by atopic patients effectively with almost no side-effect.
