This study was conducted to investigate nutritional knowledge, dietary attitudes, and dietary behaviors of adult women, and to examine if these characteristics were different by acne status. Subjects were 106 adult women residing in Seoul recruited from clients and employers at skin care centers, and housewives from apartment complexes. Surrey instrument was adapted or modified based on literature review and dietary intakes were assessed using 24-hour recalls for two days and CAN-pro. All data was statistically analyzed using x$^2$test and ANOVA. When examined by acne status, 41.5% of subjects were categorized into acne group, 20.8% were as ex-acne group, and 37.7% as no-acne group. Parental experience of acne was significantly related to acne status(p〈 0.01). Education, employmental status, and smoking or drinking status were not related to acne status. Subjects had a moderate level of nutritional knowledge(72.7 point) and the nutritional knowledge store was not significantly different by acne status. When examined by individual items, the groups showed significant difference on the items regarding vitamin C and necessity of carbohydrates(p 〈 0.05). Subjects showed favorable dietary attitudes. Although the acne group showed more favorable attitudes on the importance of nutrition on acne, the overall dietary attitudes of the acne group were not significantly different from the ex-acne group or no-acne group. Similarly only small differences were noticed in dietary behaviors or nutrient intakes by acne status. Cholesterol consumption was hitgher in the no-acne group than in the acne group or ex-acne group(p 〈 0.01). The intakes of energy, iron, and calcium was much below the RDA in three groups. Although there were not many significant differences in nutritional knowledge, dietary attitudes, and dietary behaviors by acne status, this study provided some baseline information regarding study variables by acne status.

Acne, also known as Acne vulgaris, is a common disorder of human skin involving the sebaceous gland and Propionibacterium acnes (P. acnes). The purpose of this study was to demonstrate whether anti-acne herbal complex (AAHC), a functional extract from herbal complex can be used for acne treatment as a natural product. We first demonstrated anti-acne activity of AAHC in mouse acne model. Acne was induced by injecting P. acnes on the backside $2{\times}10^7$ CFUs in ICR mice and then the mice were treated with AAHC by dermal application once daily. ACFREE$^{(R)}$ (clindamicin phosphate) was used as a positive control. Treatment with AAHC decreased the P. acnes-induced skin swelling and inflammation. AAHC treatment significantly decreased serum DHT concentration in acne-induced mice. Especially, treatment of 20% AACH in mice was more effected than 40%. We next evaluated the antimicrobial property of AAHC against P. acnes, Staphylcococcus aureus (S.aureus), and Escherichia coli (E. coli). Incubation of P. acnes, S. aureus, and E. coli with AAHC showed minimal inhibitory concentration (MIC) values against the bacterial growth lower. Alamar blue method was also carried for the antibacterial activity. It was effectively MIC level at 6.25% of P. acnes. AAHC effectively inhibited the growth of S. aureus and E. coli at 0.097% on MIC level, respectively. Our results showed the potential of using AAHC as an alternative treatment for antibiotic therapy of acne and the application of AAHC as a herbal medicine for acne treatment.

Acne vulgaris, the most common skin disease. can be formed as only a few comedons or severe inflammatory lesions. The pathogenesis of acne involves various factors; excessive androgen, excessive sebum production, abnormal alteration of follicular epithelium, proliferation of Propionibacterium acnes, and inflammation. We investigated acne therapy using oriental herbs described in the Korean traditional medical book (Dong-ui-bo-gam). Oriental herbs (Angleica daurica. Arctium lappa. Coptidis rhizoma, and glycyrrhiza glabra) were chosen based on their respective property of sebum control, anti-inflammatory activity, and anti-bacterial activity. We examined the effect of acne treatment, in terms of chemotactic inhibition, lipogenesis inhibition, and anti-bacterial activity for P. acnes. 1. Neutrophil chemotaxis assay ; P acnes secrete chemotactic factors and other pro-inflammatory extracellular products. Neutrophil chemotactic activity of P. acnes was measured by 48-well chemotaxis method. Angelica daurica clearly suppressed chemotactic activity of P. acens. 2. Using sebaceous gland of hamster ear lipogenesis assay; Sebaceous lipogenesis was measured using ear biopsies by incubation of $C^{14}$ -acetate in culture media. The $C^{14}$ -labeled lipids were extracted and determined by liquid scintilation counting, Coptidis rhizoma markedly inhibited sebum production, 3. Anti-bacterial assay for P. acnes (MIC test) Glycyrrhiza glabra showed anti-bacterial activity. P. acnes did not develop resistance against Glycyrrhiza glabra. Retinoids are effectively to inhibit sebum production and regulate follicular keratinization process, with little anti-inflammatory activity. Angelica daurica suppressed neutrophil chemotaxis. Coptidis rhizoma inhibited sebum production, and Glycyrrhiza glabra showed anti-bacterial activity against P. acnes. A combined formulation of Angelica daurica.

본 연구는 여드름을 유발하는 세균인 Propionibacterium acnes에 대해 다양한 토양에서 분리된 세균 균주들의 항균효과를 조사하기 위해 수행되었다. 수백 개의 분리 세균균주 중 Paenibacillus elgii DS381과 Paenibacillus elgii DS1515, Burkhoderia gladioli DS518, Streptomyces lienomycini DS620는 2가지 균주의 P. acnes에 대해 높은 항균활성을 나타내었다. 이 분리균주들은 agar well diffusion test에서 15.5~34.3 mm 직경의 저해대를 형성하였으며, 특히 DS620는 가장 큰 저해대 직경(28.3~34.3 mm)을 나타내었다. 분리 균주가 생성하는 항균 물질은 DS381과 DS1515 균주의 경우lipopeptide (pelgipeptin, paenipeptin), DS518은 protease, 그리고 DS620은 anthracycline 인 것으로 추정되며, 이들 모두 P. acnes에 대해매우낮은 최소저해농도를 나타내었다[DS381와 DS1515 (0.078 mg/ml), DS518 (0.312 mg/ml), DS620 (0.000078 mg/ml)]. P. acnes를 대상으로 한 time-kill assay에서는 네 균주의 항균물질이 모두 24시간 이내에 P. acnes를 완전히 사멸시켰다. 이 결과는 네 가지 항균활성 균주들이 분비하는 항균물질들이 여드름을 유발하는 P. acnes에 대하여 효율적인 치료 소재로 사용될 수 있는 가능성을 보여준다.

여드름은 만성 염증 질환으로 주로 청소년기에 발생하는 것으로 알려져 있으나 대기오염, 약물 남용 등의 원인에 의해 아동기 및 성인기에도 나타날 수 있다고 알려져 있다. 여드름을 유발하는 정확한 원인은 밝혀져 있지 않으나 한 가지 원인보다 스트레스, 호르몬의 변화, 유전, 외부 환경 등 다양한 요인들이 복합적으로 작용한다고 여겨지고 있다. Propionibacterium acnes (P. acnes)는 여드름을 유발하는 균으로 모낭 내에 상주하여 피지의 중성지방을 분해하고 유리 지방산을 형성하여 모낭 내 염증을 유발한다. 따라서 피지의 생성 증가는 P. acnes의 생존에 좋은 영향을 주고 피부에서 염증반응을 유발하는 monocytic cell의 활성화와 염증성 사이토카인(pro-inflammatory cytokine)의 증가를 유발한다. 따라서 여드름 치료를 위해서는 P. acnes의 증식 억제 및 염증반응을 최소화하는 것이 중요하다. 본 논문에서는 유칼립투스(Eucalyptus globules) 추출물이 P. acnes에 의한 염증반응에 나타내는 효과를 확인하고자 하였다. 유칼립투스 추출물 처리는 P. acnes가 유도하는 염증 매개자로 알려진 $TNF-{\alpha}$, $IL-1{\beta}$, IL-2와 인플라마좀 복합체인 NLRP3의 유전자 발현을 효과적으로 감소시키는 것을 확인하였다. 뿐만 아니라 염증성 사이토카인의 유전자 발현에 중요하다고 알려진 전사인자(transcription factors) $NF-{\kappa}B$와 NFAT의 활성 역시 유칼립투스 추출물을 처리하였을 때 감소하는 것을 알 수 있었다. 따라서 본 논문을 통해 유칼립투스 추출물이 P. acnes에 의해 초래되는 여드름의 치료 보조제로 사용될 수 있으며, 천연 추출물의 사용이 항생제 장기 복용으로 인해 유발되는 항생제 내성을 해결하는 좋은 대안이 될 것이라고 예상할 수 있다.

본 연구는 예로부터 민간요법 및 한방에 유용한 약재로 사용되어지고 있는 관중(Dryopteris crassirhizoma Nakai)을 이용하여 Propionibacterium acnes에 대한 항균활성을 평가하고, 이를 토대로 여드름 억제 및 치료에 관련된 화장품 소재를 개발하는데 그 목적이 있다. P. acnes에 대한 관중 crude 추출물 및 헥산분획물의 minimum inhibitory concentration (MIC) 및 paper disk diffusion assay로 항균 효과를 측정하였으며, 추출물에 대한 온도 및 pH 변화에 따른 안정성을 평가하였다 추출물을 이용한 P. acnes에 대한 MIC 값은 관중 crude 추출물은 0.008 mg/mL, 헥산추출물은 0.001 mg/mL로 측정되었으며, 이는 대조군으로 사용한 항생제인 triclosan의 MIC 값(0.004 mg/mL)과 비교했을 때 시료가 관중 crude 추출물 및 헥산 분획물임을 고려하면 매우 항균활성이 높은 것으로 평가되었다. 추출물에 대한 paper disk diffusion assay를 수행한 결과, 대조군으로 사용한 triclosan과 대비, 높은 활성을 나타내는 것으로 측정되었으며, HaCaT 세포에 대한 독성은 $20{\mu}g/mL$ 이하의 농도에서는 나타나지 않았다. 관중추출물의 온도, pH 안정성을 평가한 결과, 25, 70, 80, 90, 100, $121^{\circ}C$ 등 다양한 온도 조건과 $pH 2{\sim}pH 11$의 변화에 있어서도 그 효능이 변하지 않고 안정된 상태로 유지되는 것으로 관찰되었다.

여드름은 일반적인 피부 염증성 질환으로 알려져 있다. 여드름은 모낭 내 피지선에서 나타나는 만성 염증 질환이다. Propionibacterium acnes (P. acnes)의 증식은 대식세포가 염증성 사이토카인을 분비하도록 자극한다. 최근 연구에서 여러 천연 추출물이 P. acnes에 의해 매개되는 염증반응을 감소시키는 것을 확인하였다. 그러나 P. acnes에 의한 염증반응에서 E. persicifolia Gagnep. (E. persicifolia) 추출물의 억제효과에 관한 연구는 수행되지 않았다. 따라서 본 연구에서는 P. acnes에 의해 유도된 염증 반응에서 E. persicifolia 추출물의 항 염증효과를 조사하였다. P. persicifolia 추출물은 마우스 대식세포주인 RAW 264.7에서 P. acnes에 의해 유도된 IL-$1{\beta}$, IL-6, TNF-${\alpha}$ 및 iNOS와 같은 염증 매개체의 발현 수준을 억제하였다. 또한 E. persicifolia 추출물이 염증성 사이토카인 발현의 주요 조절인자인 NF-${\kappa}B$ 전사 활성화를 억제한다는 것을 발견했다. 본 연구 결과는 P. acnes의 치료를 위한 잠재적인 치료물질로서 E. persicifolia 추출물을 제안한다.

This study was carried out to analyse a perception on acne for the Junior college students to provide basic data for the suitable treatment of acne to the students and the specialists. For this study, self-administering questionnaires were distributed to 480 students from 13 departments at a suburban women's junior college from May 1 to May 3, 1996. Of the students, 399 were responded and included in the analysis. The questionnaire includes the general question of objects, the question of knowledge and attitude of acne, and its treatment. The results were as follows: 1. Age distribution for the group less than 20 years was 63.7% and over 20 years was 36.3%, the group with acne was 66.2% and the group without acne was 33.8%. Proportions of acquiring the knowledge on acne was 49.6% from newspaper or magazine, 47.15 from friends, and 26.85 from TV or radio. 2. With regard to the knowledge on the presence of acne, a proportion of correctly answered for the question on the cause of acne was $3.41{\pm}1.02$ for the group with acne compared with $3.16{\pm}0.89$ for those without acne. This difference was statistically significant (p<0.05). 3. With regard to the knowledge levels on the treatment of acne, a proportion answered' skin-care center' for the question on where to select for the profer treatment was $13.21{\pm}1.88$ compared with $12.09{\pm}1.88$ for the other group. This difference was statistically significant (p〈0.05). A proportion of answered 'squeezing out acne by themselves' for the question of how to treat was $12.26{\pm}1.91$ compared with $10.83{\pm}1.25$ for the other group. 4. In the treatment according to the attitude of the group with acne, the positive group replied 'YES' in the intention of treatment by themselves was 55.9%. In conclusion, the differences in the knowledge and attitude on the presence of acne are not significant and it was found that the knowledge and attitude for the group with acne did not significantly influenced the treatment behavior. Accordingly, it is important to understand the cause of acne, provoking factors, remedy etc. For this, it is necessary to a provide an accurate information to professionals to enhance the knowledge of acne and to treat it properly.
