  • To investigate the clinical aspects of CHT in atopic dermatitis (AD) treatments, the effect of CHT in anti-oxidative and anti-inflammatory cytokines were tested. 100% or higher cell viability was observed in all tested groups from 25 to 200 ${\mu}g/m{\ell}$ using Raw 264.7 cells. CHT showed dose-dependent DPPH scavenging activity, with more than 90% scavenging activities at 800 ${\mu}g/m{\ell}$ concentrations. CHT showed dose-dependent suppression activity of ROS production, especially at 200 ${\mu}g/m{\ell}$ of 37.5%. CHT decreased NO production activity, with significant decrease of 33.2% at 200 ${\mu}g/m{\ell}$. IL-6, MCP-1, TNF-${\alpha}$ production rate were decreased by approximately 25% when Raw 264.7 cells were treated with LPS and with CHT of 200 ${\mu}g/m{\ell}$. Also, IL-$1{\beta}$ production rate was decreased by 25% at 100 ${\mu}g/m{\ell}$. The results above indicate that CHT significantly reduces the effect of oxidative and inflammatory cytokines. The use of CHT in dermatitis can be widely suggested.

  • Anthocyanins belong to phenolic pigments and are known to have various pharmacological activities. This study aimed to investigate whether anthocyanins could inhibit hydrogen peroxide (H2O2)-induced oxidative damage in human retinal pigment epithelial ARPE-19 cells. Our results indicated that anthocyanins suppressed H2O2-induced genotoxicity, while inhibiting reactive oxygen species (ROS) production and preserving diminished glutathione. Anthocyanins also suppressed H2O2-induced apoptosis by reversing the Bcl-2/Bax ratio and inhibiting caspase-3 activation. Additionally, anthocyanins attenuated the release of cytochrome c into the cytosol, which was achieved by interfering with mitochondrial membrane disruption. Moreover, anthocyanins increased the expression of heme oxygenase-1 (HO-1) as well as its activity, which was correlated with the phosphorylation and nuclear translocation of nuclear factor-erythroid-2 related factor 2 (Nrf2). However, the cytoprotective and anti-apoptotic effects of anthocyanins were significantly attenuated by the HO-1 inhibitor, demonstrating that anthocyanins promoted Nrf2-induced HO-1 activity to prevent ARPE-19 cells from oxidative stress. Therefore, our findings suggest that anthocyanins, as Nrf2 activators, have potent ROS scavenging activity and may have the potential to protect ocular injury caused by oxidative stress.

  • 체내에서 산화스트레스에 의해 생성되는 활성산소종(reacitve oxygen species, ROS)은 당뇨병, 비만 등과 같은 만성질환을 야기시키는 것으로 알려져 있다. 고려인삼(Panax ginseng)은 수천 년간 피로 회복 및 면역증강용 기능성식품으로 이용되어 왔고, 사포닌, 산성다당체, 페놀성 화합물과 같은 다양한 생리활성 물질을 함유하고 있다. 따라서 본 연구에는 고온, 고압처리하여 제조한 신규 인삼에 대한 산화적 스트레스 저감 효능을 평가하고자 하였다. C2C12 근육세포에 산화적 스트레스를 유도하기 위해 $H_2O_2$ 1 mM 처리하고, 전처리 조건을 달리한 인삼 시료를 처리하여 cell morphology 및 항산화 관련 유전자인 SOD, CAT 및 GPx를 살펴보았고, 3T3-L1 지방세포는 분화과정 중 ROS 생성 억제효과 및 CAT, GPx 및 Cu/Zn-SOD의 항산화효소 관련 유전자의 발현 정도를 조사하였다. 고온, 고압처리한 인삼은 산화적 스트레스가 유도된 C2C12 근육세포 및 3T3-L1 지방세포에서 유의적으로 산화적 스트레스를 저감하는 것으로 나타났다. 이상의 결과로 보아, 본 연구진에 의해 개발된 고온 및 고압 처리된 인삼은 항산화 및 항피로 효능이 기대되는 바이며, 본 연구는 동물세포 수준에서의 비교이며, 보다 정확한 작용기전의 구명을 위해 향후 추가적인 연구를 통한 비교 실험이 수행되어야 할 것으로 사료된다.

  • Yukmijihwang-tang has been widely used as an and-aging herbal medicine for hundred years in Asian countries. Numerous studies show that Yukmijihwangtang has anti-oxidative effect both in vivo and in vitro. It has been reported that Moutan Cortex Radicis extract (MCR) was the most effective herb in Yukmijihwang-tang on undifferentiated PC12 cells upon oxidative-stressed with hydrogen peroxide. The purpose of this study is to; 1) evaluate the recovery of neuronal damage by assessing the anti-oxidant effect of MCR on PC12 cells differentiated with nerve growth factor (NGF), 2) identify candidate genes responsible for anti-oxidative effect on differentiated PC12 cells by oligonucleotide chip microarray. PC12 cells, which were differentiated by treating with NGF, were treated without or with hydrogen peroxide in the presence or absence of various concentration of MCR. Cell survival was determined by using MTS assay. Measurement of intracellular reactive oxygen species (ROS) generation was determined using the H2DCFDA assay The viability of cells treated with MCR was significantly recovered from stressed PC12 cell. In addition, wide rage of concentrations of MCR shows dose-dependent inhibitory effect on ROS production in oxidative-stressed cells. Total RNAs of cells without treatment(Control group), only treated with H₂O₂ (stressed group) and treated with both H₂O₂ and of MCR (MCR group) were isolated, and cDNAs was synthesized using oligoT7(dT) primer. The fragmented cRNAs, synthesized from cDNAs, were applied to Affymetrix GeneChip Rat Neurobiology U34 Array. mRNA of Calcium/calmodulin-dependent protein kinase II delta subunit(CaMKII), neuron glucose transporter (GLUT3) and myelin/oligodendrocyte glycoprotein(MOG) were downregulated in Stressed group comparing to Control group. P2X2-5 receptor (P2X2R-5), P2X2-4 receptor (P2X2R-4), c-fos, 25 kDa synaptosomal attachment protein(SNAP-25a) and GLUT3 were downregulated, whereas A2 adenosine receptor (A2AR), cathechol-O-methyltransferase(COMT), glucose transporter 1 (GLUT1), EST223333, heme oxygenase (HO), VGF, UI-R-CO-ja-a-07-0-Ul.s1 and macrophage migration inhibitory factor (MIF) were upregulated in MCA group comparing to Control group. Expression of Putative potassium channel subunit protein (ACK4), P2X2A-5, P2X2A-4, Interferon-gamma inducing factor isoform alpha precursor (IL-18α), EST199031, P2XR, P2X2 purinoceptor isoform e (P2X2R-e), Precursor interleukin 18 (IL-18) were downregulated, whereas MOO, EST223333, GLUT-1, MIF, Neuronatin alpha, UI-R-C0-ja-a-07-0-Ul.s1, A2. adenosine receptor, COMT, neuron-specific enolase (NSE), HO, VGF, A rat novel protein which is expressed with nerve injury (E12625) were upregulated in MCR group comparing to Stressed group. The results suggest that decreased viability and AOS production of PC12 cell by H₂O₂ may be, at lease, mediated by impaired glucose transporter expression. It is implicated that the MCR treatment protect PC12 cell from oxidative stress via following mechanisms; improving glucose transport into the cell, enhancing expression of anti-oxidative genes and protecting from dopamine cytotoxicity by increment of COMT and MIF expression. The list of differentially expressed genes may implicate further insight on the action and mechanism behind the anti-oxidative effects of herbal extract Moutan Cortex Radicis.

  • The stems and branchs of Euryale ferox Salisbury (EF), are used in Chinese herbal medicine for latent-heat-clearing, antipyretic, detoxicant and anti-inflammatory ailments. This plant is used worldwide for the treatment of many types of inflammatory disease including respiratory infections, diabetes mellitus, rheumatoid arthritis and play an important role in the immune reaction. Topical natural antioxidants are a useful strategy for the prevention of oxidative stress mediated inflammatory disease. Plants produce significant amounts of antioxidants to prevent the oxidative stress caused by photons and oxygen, therefore they represent a potential source of new compounds with antioxidant activity. This study was designed to evaluate whether EFEA (ethylacetate fraction of EF) may ameliorate oxidative stress and inflammatory status through the antioxidative mechanism in LPS-stimulated RAW 264.7 murine macrophage cell line. Treatment of RAW 264.7 cells with EFEA significantly reduced LPS-stimulated inflammatory response in a dose-dependent manner. In conclusion, the EF extracts have anti-inflammatory effects in vitro system, which can be used for developing pharmaceutical drug against oxidative stress and chronic inflammatory disease.

  • 본 연구에서는 감마선 조사가 총목피 추출물의 생리활성에 미치는 영향을 검토하였다. 감마선 조사한 총목피의 감마선 조사여부를 확인하기 위하여 전자스핀공명(ESR) 분석을 시행한 결과 대칭적인 unspecific central ESR 신호 좌우로 cellulose를 함유한 조사 식품에서 나타나는 한 쌍의 peak가 6.0 mT의 공간을 두고 나타나 감마선을 조사한 시료로 판별되었다. 감마선 조사된 총목피의 최적 추출조건은 10 kGy를 조사한 시료를 50% ethanol을 사용하여 15시간 추출이었다. 감마선을 조사한 총목피의 항산화 효과를 확인한 결과 DPPH radical 소거효과와 ABTS radical 저해는 총목피의 물 추출물과 50% ethanol 추출물의 경우, 비조사구와 조사구를 저 농도인 $50{\mu}g/m{\ell}$ 처리하였을 때 각각 80%와 98% 이상의 매우 높은 저해 효과를 나타내었다. 지용성 물질의 항산화 활성의 지표인 antioxidant Protention Factor (PF)는 2.18~2.78 PF로 매우 높은 PF값을 나타내었다. TBARs의 경우 물과 ethanol 추출물 모두 높은 TBARs값을 나타내었다. 물 추출물은 감마선의 조사에 의한 TBARs 저해능의 상승은 관찰되지 않았으나, ethanol 추출물은 10 kGy의 감마선조사에 의해 TBARs 저해능의 상승이 약하게 관찰되었다. 이상의 결과 총목피는 감마선의 조사에 의해서 총목피의 phenolic 성분들의 용출율과 항산화 효과가 증대되는 현상을 확인하였다. 또한 감마선 조사가 식물체로부터 생리활성물질의 용출 증대와 항산화 활성을 증폭시킬 수 있는 수단으로 활용이 가능할 것이라 판단되었다.
