산수유 종자 추출물의 천연 방부제로서 가능성을 평가하기 위하여 항균활성 및 화장품 방부 효능 평가를 실시하였다. 산수유 종자는 각각 1,3-부틸렌글리콜과 에탄올을 이용하여 추출하였다. Paper disc method로 항균활성을 평가한 결과 Staphylococcus aureus, Staphylococcus epidermidis와 Propionibacterium acnes에서 항균활성이 나타났으며 산수유 종자 1,3-부틸렌글리콜 추출물(COS-A)이 여드름균에대해 $26.7{\pm}4.0mm$로 가장 높았다. 최소저해농도(MIC) 측정 결과 산수유 종자 에탄올 추출물(COS-B)이 가장 낮은 농도에서 S. epidermidis균의 생장을 억제하였다. 에멀션에서의 방부효능 평가를 위해 Challenge test를 실시한 결과 COS-A와 COS-B를 첨가한 에멀션에서 균 접종 7일 후 피부상재균이 100% 사멸되었다. 이러한 결과는 산수유 종자 추출물이 화장품에서 합성방부제를 대체할 천연 방부제로서 가능성이 있을 것으로 사료된다.

Acne is a common chronic disease which most frequently affects the face, appearing in both males and females near puberty, and in most cases becomes less active as adolescence ends. The intensity and duration of activity vary for each individual. The disease may be minor, with only a few comedones or papules, or it may occur as the highly inflammatory and diffusely scarring acne conglobation. Permanent scarring of the skin and psyche can result from such inaction. The disease, however, has implications far beyond the few marks that may appear on the face. The lesions cannot be hidden under clothing; each is prominently displayed and detracts significantly from one's personal appearance and self-esteem. Recently many of acne patients are visiting to Oriental Medicine Hospitals. They want to receive the treatment of acne related another disease and causes, or worry about side effects of antibiotics and hormone therapy. This study was performed at Pundang Cha Oriental Medicine Hospital Department of Dermatology from March 1, 1997 to February 29, 2000 in 31 patients with recurrent acne. We investigated the clinical findings, included distribution of age & sex, severity of acne, sites on face, related causes, duration of disease and causes of visiting Oriental Medicine Hospital and so on. The results were as follows : The peak age at onset was 20-29 years old in females with 16 cases reported. The 22 total cases patients had severe signs with most frequently sites being forehead & chin. They visited Oriental Medicine Hospital because they want to take the treatment of acne related with another body problems(12 cases) and worry about side effects of antibiotics. Twenty cases were diagnosed 肺熱血熱(20 cases). And given acupuncture treatment, herb-medication and sometimes we used external applications. Relatively, their satisfaction grade was high. Dermatologists are trying to treat new methods in order to remove scar and decrease sebaceous gland secretion,. And we, Oriental Medicine doctors, have to develop and offer to patients the most effective management and successful treatment of this disease.

Bee venom (BV) has been used as a treatment for a wide variety of ailments such as inflammatory diseases in korean traditional medicine. Despite its well documented anti-inflammatory property, it has not been fully demonstrated regarding the influence of BV against Propionibactierium acnes (P. acnes), which promotes follicular inflammation (inflammatory acne). This study evaluated the anti-inflammatory property of BV against P. acnes in vivo. To induce inflammation in vivo using P. acnes, $1{\times}10^7$ CFU of living P. acnes were intradermally injected into the ear of mice. BV (1, 10, 100 ${\mu}g$) in vaseline was applied epicutaneously on the ear resulting in P. acnes-induced ear swelling and inflammation. Epicutaneous administration of BV with P. acnes decreased the number of infiltrated inflammatory cells and inflammatory cytokines in the ear, thereby relieving P. acnes-induced ear swelling and granulomatous inflammation, especially at the dose of 1 ${\mu}g$ of BV. In this report, we demonstrated the therapeutic effects of BV on P. acnes-induced inflammation in vivo using the mouse model. These data highlight the potential of using BV as an alternative treatment to the antibiotic therapy of acne vulgaris.

Acne is a relatively common disorder, especially in the adolescent or 20-30th young people. The condition is characterized by comedones, papules and pustules. Acne has social and psychological influence on the acne patients. But there is no perfect treatment of acne. It is known that Herba Houttuyniae has anti-inflammatory action and anti-bacterial action. Therefore, we studied the effect of 5% Herba Houttuyniae extract solution on the acne. The study was designed to compare the efficacy of 5% Herba Houttuyniae solution on the acne. The study was carried out on two groups-a experimental and a control group- for 4 weeks. Efficacy was determined by investigating counts of non-inflammatory open and closed comedones, and inflammatory papules and pustules once a week. After a experiment self-assessment was checked. As the result of the study, we found that a significant difference was observed in the mean counts and self-assessment of the experimental group. So we concluded that Herba Houttuyniae has a clinical effect on the acne.

Objective : This experimental study was performed to investigate the effects of Houttuyniae Herba extract on anti-inflammation and anti-oxidation. Methods : The cytotoxicity of Houttuyniae Herba water extract and ethanol extract about viability of Raw 264.7 cell were tested using a colormetric tetrazolium assay(MTT assay). We investigated the inhibitory effects of Houttuyniae Herba water extract and ethanol extract on Propionibactrium acnes using paper disk diffusion method. To investigate the anti-inflammation effects of Houttuyniae Herba water extract and ethanol extract on LPS-induced macrophage Raw 264.7 cell, we used ELISA kit. We evaluated anti-oxidation effects of Houttuyniae Herba water extract and ethanol extract on HaCaT cell by Enzyme recycling method. Results : 1. In Houttuyniae Herba water extract and ethanol extract, cell toxicity depended on the density and wasn't difference between two extracts. 2. Houttuyniae Herba water extract and ethanol extract has not the significant inhibition effect of Propionibactrium acnes. 3. Concentration of 50, $100{\mu}g/m{\ell}$ Houttuyniae Herba water extract inhibited the production of NO in the Raw 264.7 cell stimulated with LPS. 4. All extracts except for $20{\mu}g/m{\ell}$ Houttuyniae Herba water extract showed anti-oxidation effect by decreasing the DPPH radicals. Conclusion : These results indicate that Houttuyniae Herba extract has anti-inflammation and anti-oxidation effects. If further study is performed, the use of Houttuyniae Herba extract will be valuable and benificial in the therapy of Propionibactrium acnes.
