Objectives: The purpose of this study was to investigate the antineoplastic effect of several herbal medicine mixtures (compositions of Astragalus membranaceu, Angelica gigas, Trichosanthes kirilowii, Panax ginseng, Rhus verniciflua Stokes) on the SNU-80 anaplastic thyroid carcinoma cell line. Methods: MTT assay was used to examine whether our herbal medicine mixtures decreased cell growth rate of SNU-80. Wound healing assay and Transwell invasion assay was performed to investigate whether our herbal medicine mixtures affect the migration and invasion of anaplastic cancer cells, SNU-80. ELISA assay was performed to know if our herbal medicine mixtures suppressed the expression of pro-invasive molecules, such as vascular endothelial growth factor (VEGF) and matrix metalloproteinase-2 (MMP-2) secreted from SNU-80. Results: MTT assay demonstrated that A. membranaceus:A. gigas:T. kirilowii=1:1:1 or 3:1:1, A. membranaceus:A. gigas :T. kirilowii:P. ginseng=1:1:1:1 or 3:1:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng:R. verniciflua Stokes=1:1:1:1:1 or 3:1:1:1:1 strongly suppressed the growth of SNU-80. Wound healing assay demonstrated that A. membranaceus:A. gigas=3:1, A. membranaceus:A. gigas:T. kirilowii=1:1:1 or 3:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng=1:1:1:1 or 3:1:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng:R. verniciflua Stokes=1:1:1:1:1 or 3:1:1:1:1 inhibited the migration of SNU-80. Transwell invasion assay demonstrated that A. membranaceus:A. gigas=1:1, A. membranaceus:A. gigas:T. kirilowii =1:1:1 or 3:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng=1:1:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng :R. verniciflua Stokes=1:1:1:1:1 or 3:1:1:1:1 inhibited the invasion of SNU-80. ELISA assay demonstrated that A. membranaceus :A. gigas:T. kirilowii=1:1:1 or 3:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng:R. verniciflua Stokes=1:1:1:1:1 suppressed the expression of VEGF. Also, A. membranaceus:A. gigas=1:1, A. membranaceus:A. gigas:T. kirilowii=1:1:1 or 3:1:1, A. membranaceus :A. gigas:T. kirilowii:P. ginseng=1:1:1:1 or 3:1:1:1, A. membranaceus:A. gigas:T. kirilowii:P. ginseng:R. verniciflua Stokes =1:1:1:1:1 or 3:1:1:1:1 suppressed the expression of MMP-2. Conclusions: The results obtained in this study suggest that several herbal medicine mixtures suppresse the growth and inhibit the migration and invasion of SNU-80, which is anaplastic thyroid cancer cells. Especially, A. membranaceus:A. gigas: T. kirilowii=1:1:1 mixture had a stronger anti-cancer effect.

Objectives : Increased oxidative stress by reactive oxygen species (ROS) has been suggested as a major cause of muscle fatigue. Although several studies have demonstrated the various biological properties of Sophora flavescens Aiton, Glycyrrhiza uralensis Fischer and Dictamnus dasycarpus Turcz, but the antioxidative potentials have not been clearly demonstrated. The present study was designed to investigate the protective effects of their water and ethanol extract mixtures (medicinal herbal mixtures, MHMIXs) on hydrogen peroxide ($H_2O_2$)-induced cell damage and apoptosis in C2C12 myoblasts. Methods : Cytotoxicity was assessed by an MTT assay. Quantitative evaluation of apoptosis induction and ROS production was evaluated by flow cytometry analysis. Expression levels of apoptosis regulatory and DNA-damage proteins were detected by Western blotting. Result : The inhibition of $H_2O_2$-induced cell proliferation was effectively blocked in extracts of 3: 1: 1 (EMHMIXs-1) or 2: 2: 1 (EMHMIXs-2) of S. flavescens, G. uralensis and D. dasycarpus Turcz, ethanol extracts from various complex extracts in C2C12 myoblasts. EMHMIXs-1 and EMHMIXs-2 also effectively attenuated $H_2O_2$-induced C2C12 cell apoptosis, which was associated with the restoration of the upregulation of Bad and death receptor 4, and downregulation of XIAP and cIAP-1 induced by $H_2O_2$. In addition, these herbal mixtures significantly blocked the $H_2O_2$-induced ROS generation and phosphorylation of $p-{\gamma}H2A.X$, which suggests that they can prevent $H_2O_2$-induced cellular DNA damage. Conclusions : The results suggest that EMHMIXs-1 and EMHMIXs-2 could block the DAN damage and apoptosis of C2C12 myoblasts by oxidative stress through blocking ROS generation.

고삼, 감초 및 백선피는 염증성 질환 치료를 위한 목적으로 오랜 동안 사용되어 온 한약제이다. 본 연구에서는 이들 한약제의 에탄올 추출물과 각 한약제 추출물의 복합물에 대한 항염증 효능을 LPS에 의하여 활성화되는 RAW 264.7 대식세포 모델을 사용하여 평가하였다. 이를 위하여 고삼 추출물(EESF), 감초 추출물(EEGU), 백선피추출물(EEDD) 및 추출복합물(MHMIXs)을 준비하였으며, 항염증 효능 평가를 위한 인자로서 대표적인 염증 매개인자로서 NO와 $PGE_2$를, 염증성 cytokine 중에서는 $IL-1{\beta}$와 $TNF-{\alpha}$를 선정하였다. 본 연구의 결과에 의하면, 각 한약제 단독 추출물 및 추출복합물은 LPS로 활성화된 RAW 264.7 대식세포에서 NO와 $PGE_2$ 및 염증성 cytokine의 생성을 모두 억제하였으며, 이러한 생성 억제는 해당 단백질의 발현 억제를 통해 이루어졌다. 비록 각각의 단일 추출물과 추출복합물이 항염증 효과가 우수하다고 평가되지만, 세포 독성과 다양한 염증성 매개인자 및 cytokine의 억제 효과를 전체적으로 고려할 경우 EESF, EEGU 및 EEDD가 3:1:1로 혼합된 MHMIX-1이 항염증 관련약품 및 소재 개발에 보다 효과임을 제안하며, 이는 과도하게 활성화된 대식세포에 의한 염증성 질환 조절에 매우 유용하게 사용될 수 있을 것으로 추정된다.
