한의학에서 승마(Cimicifuge dahurica, C. dahurica), 황련(Coptis chinensis, C. chinensis), 황백(Phellodendri amurense, P. amurense) 추출물은 해독작용을 하며 후박(Magnol obovata, M. obovata) 추출물은 항균 효과가 있다고 알려져 있다. 본 연구에서는 승마, 황련, 황백, 후박 추출물을 혼합하여 기능성 화장품 소재로써의 이용 가능성을 검토하였다. MTT assay를 이용한 세포 독성평가와 DPPH와 ABTS를 이용한 항산화 효과를 측정한 결과, 단일 추출물보다 추출혼합물이 더 안전함을 확인 하였으며 농도 의존적으로 항산화 활성이 증가됨을 확인하였다. 뿐만 아니라 NO 생성을 억제함으로써 우수한 항염증 효과가 있을 것으로 예상되며, 섬유아세포에서 UVB로 유도된 세포 손상을 보호하면서 type 1 pro-collagen 합성량이 증가되는 것을 관찰하였다. 또한 추출 혼합물은 melanin 합성과 tyrosinase 활성 및 melanin 합성 관련 인자 및 효소들(MITF, tyrosinase, TRP-1, TRP-2)의 발현을 효과적으로 억제하였다. 이러한 연구결과로 보아 승마, 황련, 황백, 후박 추출 혼합물은 항노화 및 미백 등 기능성 화장품 소재로써 개발 가능성이 높을 것으로 사료된다.

Gyejijakyakjimo-tang is a multi-herbal formula that is composed of nine medicinal herbs. Gyejijakyakjimo-tang has been reported to have antipyretic and analgesic effects. Gyejijakyakjimo-tang has traditionally been used for goat and rheumatoid arthritis. However, analgesic and antiinflammatory effects of Gyejijakyakjimo-tang has not been clarified yet. In this study, we investigated the analgesic and anti-inflammatory effect of the aqueous extract of Gyejijakyakjimo-tang. We evaluated the aqueous extract of Gyejijakyakjimo-tang on Lipopolysaccharide (LPS)-induced inflammation in murine raw 264.7 macrophage cells. For this study, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, reverse transcription-polymerase chain reaction (RT-PCR), prostaglandin $E_2$ ($PGE_2$) immunoassay, and nitric oxide (NO) detection were performed. Gyejijakyakjimo-tang suppressed $PGE_2$ synthesis and NO production by inhibiting the LPS-induced expressions of COX-2 and iNOS mRNA in murine raw 264.7 macrophage cells. These results show that Gyejijakyakjimo-tang has the analgesic and anti-inflammatory effect by mostly suppressing COX-2 and iNOS expressions, and resulting in the inhibition of $PGE_2$ synthesis and NO production.

This study was indicated to enhance the anti-inflammation activities by the fermentation of the fruits of Aronia melanocarpa (Michx.) Elliott. The extracts by 70% ethanol (EE) showed better biological activities than those by hot water (WE) from campared result of the effect of extraction solvents. Then, the extract from 70% ethanol extraction was further fermented by lactic acid, denoted as FEE. For antioxidant activities, the FEE had showed the highest value as 0.832 of reducing powder, in comparison with those of EE and WE. Cytotoxicity of the water extraction (WE) was measured for 12.06% in addition of $1.0mg/m{\ell}$ of FEE. For anti-inflammation activities, NO production from the macrophage, RAW 264.7 was observed as $7.24{\mu}M$ and $8.52{\mu}M$ from FEE and EE, respectively. Prostaglandin $E_2$ ($PGE_2$) production from human fibroblast cell, CCD-986sk, was also estimated for $152pg/m{\ell}$ in addition of $1.0mg/m{\ell}$ of the FEE. The lowest production of both IL-6 and TNF-${\alpha}$ were $3.5pg/m{\ell}$ and $865.5pg/m{\ell}$, respectively in addition of $1.0mg/m{\ell}$ of the FEE, whereas $74.5pg/m{\ell}$ and $982.4pg/m{\ell}$ in treated with same concenrations of the EE. It was also found that the FEE was higher amounts than other extracts through HPLC analysis of the anthocyanins. These results strongly indicate that fermentation process of the lactic acid could enhance anti-inflammation activities of extracts by increasing the amounts of the anthocyanins, especially cyanidin-galactoside. Our results suggest that the application of the fermentation process for other medicinal herbs can be improved their biological activities.

Objectives : Danguieumja is a traditional medicinal prescription to treat skin disease. It was commonly used for the treatment of itching, chronic urticaria and atopic dermatitis in Korea by the addition or omission of several herbs. This study investigated the anti-inflammatory potential of Gagam-Danguieumja (GDE) water extract. Methods : We examined the effects of GDE on the lipopolysaccharide (LPS)-induced production of nitric oxide (NO) in a murine macrophage cell line, RAW 264.7 cells. Results : GDE inhibited production of NO in a dose dependent manner and also decreased the expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2). As a possible molecular mechanism of anti-inflammatory effect increased phosphorylation of mitogen-activating protein kinases (MAPK) by LPS were blocked by GDE treatment. Conclusions : These results suggest that GDE has an anti-inflammatory therapeutic potential through the inhibition of MAPK phosphorylation, thereby decreasing the expression of pro-inflammatory genes.
