The cosmetics industry expects skin improvement and anti-aging effects by using natural products and natural extracts. In particular, herbal extracts are ingredients with traditionally proven pharmacological efficacy, and are in the spotlight as effective ingredients for maintaining skin health and improving skin troubles. In this study, the antioxidant, anti-inflammation, and wrinkle improvement effects were evaluated by using herbal ingredients such as Dioscorea opposita, Angelica dahurica, Rehmannia glutinosa, Panax ginseng and Ophiopogon japonicus. The antioxidant activity of the herbal complex was confirmed by measuring DPPH and ABTS+ radical scavenging activity, and after a cytotoxicity test using the MTT assay, it showed a concentration-dependent inhibition effect on NO production by LPS stimulation in RAW 264.7 cells. In addition, in the analysis of MMP-1, MMP-2 and procollagen gene expression induced by H2O2 in HDF cells, the expression of MMP-1 was suppressed in a dose-dependent manner by the herbal complexes. This is expected to make a significant contribution to wrinkle improvement and skin elasticity enhancement. These results suggest that herbal complexes can be used as promising cosmetic materials for skin improvement and anti-aging.

The present study was evaluated the antibacterial effect of the combination of Coptidis rhizoma,Lonicerae Flos, and Paeonia japonica (1:1:1) extracts (CLP1000). Also, the effectiveness of CLP1000, dioctahedral smectite (DHS), and the combination of CLP1000 and DHS (CLPS1000) against E. coli O157:H7 infection was studied using ICR female mice. During the incubation period, the dose of 10% and 20% CLP1000 were inhibited the growth of E. coli O157:H7 by 30% and 47%, respectively. For 7 days after single challenge with E. coli O157:H7, forty female ICR mice were divided into four experimental groups which were orally administered with saline, 10% CLP1000, 10% DHS, and 10% CLPS1000, respectively. On the 3rd day, the number of E. coli O157:H7 in mouse feces was significantly decreased by administration of CLP1000 (p < 0.05), DHS (p < 0.05) and CLPS1000 (p < 0.001). On the 7th day, CLP1000 (p < 0.05) and CLPS1000 (p < 0.001) administration significantly decreased the number of E. coli O157:H7. According to the results of the present study, administration of CLPS1000 to mice can reduce the severity of E. coli O157:H7 infection. Also, it is suggested that CLPS100 represents a good candidate for the treatment of enteric infections in domestic animals.

탈모방지 및 발모효과를 가지는 소재를 개발하기 위해 한의학에서 전통적으로 사용되는 23가지 한방소재를 선정하여 한방복합처방단을 개발하였다. 한방복합처방단을 구성하는 한방소재들은 예로부터 전통적으로 발모 및 탈모방지, 흰머리방지, 염증 치료 및 혈액순환개선 효과를 가진 것으로 알려져 있는 당귀, 보골지, 측백엽, 한련초, 구기자, 복분자, 상백피, 숙지황, 여정실, 적하수오, 흑지마, 고삼, 백지, 익모초, 단삼, 도인, 몰약, 감국, 유향, 인삼, 천궁,합환피, 현호색 등이다. 또한, 한방복합처방단의 발모효과를 확인하기 위해 in vitro와 in vivo 평가모델을 이용하여 모발성장 및 촉진에 미치는 영향을 실험하였다. In vitro 상에서는 모유두세포, 각질형성세포 및 섬유아세포의 증식을 확인하였다. 또한, 흰머리방지 효과와 관련하여 멜라노마 세포에서의 멜라닌 합성능력을 확인하였다. 한방복합처방단의 in vitro 상에서의 육모효과는 C57BL/6 마우스를 이용한 in vivo 상에서도 확인하였다. 연구 결과 한방복합처방단은 50 μg/mL의 농도에서 모유두 세포의 증식을 175 %까지, 섬유아세포인 NIH3T3 세포의 증식은 120 %까지 증가시켰으며, 20 μg/mL의 농도에서 각질형성세포인 HaCaT 세포의 증식을 133 %까지 증가시켰다. 멜라닌 합성의 경우, 50 μg/mL의 농도에서 154 %까지 증가시켰다. 또한, C57BL/6 마우스를 이용한 육모효과에 있어서는 한방복합처방단 처리 4주 후 98 % 이상의 육모효과를 나타내는 것을 확인하였다. 이상의 결과로 볼 때 본 연구에서 개발한 한방복합처방단은 모발의 성장 촉진에 유용하게 활용될 수 있는 처방으로 사료된다.
