Objective : Propionibacterium acnes (P. acnes) is a major pathogenic bacteria for acne vulgaris. This study was performed to evaluate the effects of Lithospermum erythrorhizon extracts on the inflammatory cytokines gene expression by P. acnes in human keratinocytes, HaCaT cell line. Methods : Anti-bacterial activity and cytotoxicity of LE extracts was analyzed by agar plate culture and XTT assay. The cytokines gene expressions were assessed by real time RT-PCR for IL-8, MCP-1 and TNF-${\alpha}$. During the cell culture and treatments, amounts of secreted TNF-${\alpha}$ were measured by ELISA. Translocation of transcription factor NF-${\kappa}B$ from cytoplasm into nucleus was observed by immunocytochemistry and confocal microscopy. Results : There were no anti-bacterial effects and cytotoxicity as high as $1,000{\mu}g/ml$ of LE extracts in XTT assay. Transcription levels of inflammatory cytokines, IL-8, MCP-1 and TNF-${\alpha}$ were increased by P. acnes in HaCaT. LE extracts decreased the upregulated gene transcription levels. However, amounts of secreted TNF-${\alpha}$ were similar in HaCaT cells with P. acnes and LE extracts. Translocation of NF-${\kappa}B$ into nucleus by P. acnes was significantly inhibited by LE extracts. Conclusions : From the results of this study, LE extracts have anti-inflammatory effects on HaCaT cells by P. acnes that decreased the mRNA expressions of IL-8, MCP-1 and TNF-${\alpha}$. This anti-inflammatory effects of LE extracts could provide the potential of therapeutic substance for acne vulgaris.

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 is often associated with acne-related bacteria such as Cutibacterium acnes. In this study, we investigated the antibacterial effects of the methanol extract of the algae Ecklonia cava and its solvent-soluble extract against C. acnes. Among five solvent fractions, the ethyl acetate (EtOAc) fraction exhibited the strongest antibacterial activity against C. acnes. Furthermore, the EtOAc-soluble extract exhibited the highest total phenolic contents among the five solvent fractions tested. The EtOAc subfraction 07 (Fr. 07) extract showed the highest antibacterial effect against C. acnes and isolated C. acnes along with minimum inhibitory concentration (MIC) ranging from 32 to 64 ㎍/mL. Additionally, MICs of antibiotics against antibiotic-resistant C. acnes strains were substantially reduced when antibiotics were combined with Fr. 07, suggesting that Fr. 07 restore the antibacterial activity of the antibiotics. The fractional inhibitory concentration indices clearly revealed an additive synergistic effect of Fr. 07 with antibiotics. The results of the present study suggest a potential role for E. cava in the control of infections related to acne vulgaris.

Objectives : Biological activities of marine resources have been rarely evaluated compared with other herbal medicines. In the present study, we aimed to evaluate antimicrobial activities of aqueous and ethanolic extracts of five marine resources(Porphyra tenera, Laminariae Thallus, Sargassum, Ostreae Concha, Maliotidis Concha) against Propionibacterium acnes. Methods : Aqueous axtracts of five marine resources were prepared by decocting in tenfold tap water for 3 h. Etanolic extracts were obtained by extracting five marine resources with tenfold ethanol for 72 h at room temperature. The zone of growth inhibition and minimum inhibitory concentration (MIC) were determined against P. acnes after incubation for 48 h under anaerobic condition. Results : Ethanolic extracts of Porphyra tenera exhibited potent antimicrobial effects(MIC $62.5\;{\mu}g/m{\ell}$ against KCTC3320, MIC $31.25\;{\mu}g/m{\ell}$ against KCTC5527). However, all aqueous extracts tested had no effects on the growth inhibition of P. acnes. In addition, four ethanolic extracts except Porphyra tenera showed little inhibitory effect. Conclusions : These results indicate that ethanolic extracts of Porphyra tenera has antimicrobial activities against P. acnes and also warrant further development of Porphyra tenera extracts as a natural anti-acne agent.

Propionibacterium acnes is the predominant organism in sebaceous regions of the skin and is thought to play an important role in the pathogenesis of inflamed lesions. Antibacterial compounds against P. acnes were isolated from the ethanol extract of Kaempferia pandurata Roxb. and identified as panduratin A and isopanduratin A. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of panduratin A for P. acnes were 2 and $4{\mu}g/mL$, respectively, while those of isopanduratin A were 4 and $8{\mu}g/mL$, respectively. The time-dependent killing effect showed that panduratin A and isopanduratin A completely inhibited the growth of P. acnes at 4 and $8{\mu}g/mL$ in 48 hr, respectively. Panduratin A and isopanduratin A demonstrated high antibacterial activities not only against P. acnes but also other skin microorganisms. The results suggest that panduratin A and isopanduratin A could be employed as natural antibacterial agents to inhibit the growth of acne and skin disease causing microorganisms.

본 연구에서는 인간 단핵구 세포인 THP-1 세포를 이용하여 berberine의 항염증 활성을 조사 하였다. Propionibacterium acnes의 감염은 THP-1 세포에서 산화질소(NO)와 $TNF-{\alpha}$, IL-8 및 $IL-1{\beta}$와 같은 전 염증성 사이토카인의 생산을 유도했다. 그러나, P. acnes에 의해 유도된 THP-1 세포에 berberine을 처리했을 때, 전 염증성 사이토카인 및 NO의 생성이 유의하게 감소하였다. 또한 우리는 berberine의 항 염증 기능의 신호 전달 경로를 분석하여 berberine이 P. acnes 유도 세포에서 ERK1/2, JNK 및 p38의 인산화를 억제하고 $NF-{\kappa}B$ p65의 발현 및 핵이동을 억제한다는 것을 발견했다. 이러한 결과로부터 berberine은 인간 단핵구 세포에서 $NF-{\kappa}B$ 및 MAPK 신호 전달 경로를 억제함으로써 항 염증 활성을 효과적으로 발휘할 수 있다고 결론지었다. 또한, 이러한 결과는 P. acnes에 의해 유발된 염증성 질환의 치료를 위해 천연물 소재에서 유래한 알칼로이드 화합물인 berberine을 사용하여 천연 치료제를 개발할 수 있는 가능성을 제시하였다.
