  • Gynura segetum, family Asteraceae is a cultivated species and can be found growing in the tropical regions of Indonesia and Malaysia. The plant is known for its use for the treatment of cancer, inflammation, diabetes, hypertension and skin afflictions. In the current study, anti-inflammatory effect of Gynura segetum leaf has been investigated. The present study investigated the in vivo anti-inflammatory effect of Gynura segetum leaf by using hen's egg test-chorioallantoic membrane (HET-CAM) assay. Different solvent extract of Gynura segetum leaf were tested, the most active methanol extract was further fractionated and tested. Among the extracts tested, the methanol extract showed a significant good anti-inflammatory effect (76.8% inhibition at 50 ${\mu}g/disc$) on the HET-CAM assay as compared with the anti-inflammatory drug indomethacin (82.1% inhibition). However, the fractionated sample exhibited a significantly lower activity in comparison to crude methanol extract. The results demonstrated that Gynura segetum leaf displayed remarkable anti-inflammatory effects, which support the folkloric uses of this plant for treatment of inflammation.

  • Objectives : This study was performed to investigate the anti-inflammatory and anti-oxidantic effects of GaeYongHwan(GYH) extract which has been used for patients with acnes. Methods : Anti-inflammatory and anti-oxidantic effects of GYH extract were tested in terms of inhibitory ability of Nitric oxide(NO) production, 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical scavenging activity and anti-bacterial effects against Propionibacterium acnes(P. acnes). Results : 1. All GYH treated groups did not show cytotoxicity. 2. Treatment with $100{\mu}g/m{\ell}$ of GYH extract lowered production levels of NO significantly compared to non-treated control or normal. 3. All of GYH treated groups did not show DPPH free radical scavenging activities. 4. All of GYH treated groups did not show anti-baterial action against P. acnes. Conclusions : These results imply that GYH extract has anti-inflammatory effect to treat acnes.

  • 치아의 세균들은 잇몸에서 염증반응을 일으켜서 치은염과 치주염같은 잇몸 질환의 원인이 된다. 따라서 잇몸질환의 예방과 치료를 위해서는 치아 세균에 의한 염증반응을 조절하는 것이 가장 효과적인 방법이다. 현재 대부분의 구강 관리 제품들은 살균제를 이용하여 구강 세균을 제거하는 방법을 사용하고 있다. 하지만 최근의 연구들은 심지어 열처리로 사멸된 구강 세균도 염증반응을 일으킬 수 있다는 사실을 보고하고 있다. 따라서 보다 효과적인 잇몸 염증반응억제를 위해서는 살균제를 이용한 방법에 대한 개선이 필요하다. 또한 아직까지 구강 세균에 의한 잇몸 염증반응의 기작과 효과적인 천연 염증 억제 물질들은 보고되어 있지 않다. 본 연구에서는 대표적인 치은염, 치주염 유발세균인 Prevotella intermedia와 인간의 잇몸상피세포를 이용하여, 실제로 잇몸에서 일어나는 염증반응의 기작을 연구하고, 이를 통해 효과적인 천연 잇몸 염증 완화 물질을 도출하려고 하였다. 실험 결과, Prevotella intermedia는 잇몸상피세포를 자극하여 염증매개인자인 IL-8을 분비하게 함으로써 잇몸 염증반응을 개시하였다. 또한 Prevotella intermedia에 의한 잇몸 염증반응은 기전적으로 COX-2, AP-1, TNF-${\alpha}$와 연관되어 있었으며, 녹차추출물은 Prevotella intermedia에 의한 잇몸 염증반응을 효과적으로 억제할 수 있음을 확인하였다. 따라서 본 연구는 치아 세균에 의한 잇몸 염증반응의 기전 연구를 통해서 효과적인 천연 잇몸질환 개선 물질을 도출했다는 점에서 중요한 의미를 가진다.

  • Raphanus sativus L. has been reported to have anti-inflammatory and anti-tumor activity. However, the anti-inflammatory effect and mechanism of action of the Raphanus sativus L. seeds (RSS) with or without oil are still unknown. This study was undertaken to investigate the in-vitro anti-inflammatory effect with or without oil in the RSS on RAW 264.7 cells stimulated by lipopolysaccharide (LPS). Results showed the suppressed LPS-induced secretion of pro-inflammatory mediators such as nitric oxide (NO), inflammatory cytokine (IL-6, TNF-α). Additionally, a decrease in protein expression of iNOS was observed, but nuclear translocation of NF-κB p65 was not inhibited. To elucidate the underlying mechanism of the anti-inflammatory effect of RSS, the involvement of mitogen-activated protein kinase (MAPK) signaling pathways was examined. We also found that RSS blocked LPS-induced phosphorylation of c-Jun N-terminal kinase/stress-activated protein kinase (JNK) signaling but did not affect the phosphorylation of p38 MAPK and extracellular signal-regulated kinase (ERK) 1/2. These results suggest that RSS may have potential as an anti-inflammatory agent through the inhibition of LPS-induced inflammatory cytokine production via regulation of the JNK pathway.

  • Objectives : This study was carried out to investigate the effects of Polygonum cuspidatum extract on several skin functions including inflammation and wrinkle formation. Methods : To investigate in vitro anti-oxidant activity assay, ethanol extracts of medicinal plants tested by DPPH method. In the next experiment, to investigate anti-inflammatory test, the RAW 264.7 macrophage cells was cultured using DMEM including the 10% FBS. To study anti-allergic effect, we blended cultured Human Mast Cells(HMC-1), and then observe $TNF-{\alpha}$, IL-8 by ELISA Results : Polygonum Cuspidatum extract has the effects of anti-inflammation and anti-allergy, which may be due to its inhibitory potential on the macrophage activation. Furthermore, Polygonum Cuspidatum extract has the anti-wrinkle effects through the inhibitory potential on the collagnease, elastase and gelatinase activities. Conclusions : The above results suggest that Polygonum Cuspidatum extract could be applicable for improvement of several skin functions.

  • Objectives : The purpose of this study was to investigate the molecular targets and pathways of anti-inflammatory effects of Jakyakgamchotang with corydalis tuber (JC) using network pharmacology. Methods : The compounds in constituent herbal medicines of JC were searched in TCM systems pharmacology (TCMSP). Target gene informations of the components were collected using chemical-target interactions database provided by Pubchem. Afterwards, network analysis between compounds and inflammation-related target genes was performed using cytoscape. Go enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed on inflammation-related targets using DAVID database. Results : 70 active compounds related to inflammation were identified, and 295 target genes related to the anti-inflammatory activity of the compound of JC were identified. In the Go biological process DB and KEGG pathway DB, "inflammatory response", "cellular response to lipopolysaccharide", "positive regulation of interleukin-6 production", and "positive regulation of protein kinase B. signaling", "positive regulation of ERK1 and ERK2 cascade", "positive regulation of I-kappaB kinase/NF-kappaB signaling", "negative regulation of apoptotic process", and "PI3K-Akt signaling pathway" were found to be mechanisms related to the anti-inflammatory effects related to the target genes of JC. The main compounds predicted to be involved in the anti-inflammatory effect of JC were quercetin, licochalcone B, (+)-catechin, kaempferol, and emodin. Conclusions : This study provides the molecular targets and potential pathways of JC on inflammation. It can be used as a basic data for using JC for various inflammatory disease in traditional korean medicine clinic.

  • Objectives : Bower Actinidia has been widely used for treatment of inflammatory diseases, such as jaundice, cystolithiasis. However, the mechanism of its anti-inflammatory activity has not been clarified. In this study, we investigated the inhibitory effect of Bower Actinidia pharmacopuncture extract(BA) on LPS-induced inflammation. Methods : The effect of BA was analyzed by ELISA, RT-PCR and Western blotting in LPS-stimulated RAW264.7 cells. Results : We found that BA suppressed not only the mRNA expression of pre-inflammatory cytokines, cyclooxygenase-2(COX-2) and inducible nitric oxide synthase(iNOS), but also the phosphorylation of ERK, JNK and p38. Conclusions : These results suggest that BA exerts an anti-inflammatory effect through the regulation of the mitogen-activated protein kinase(MAPK) pathway, thereby decreasing production of pre-inflammatory cytokines.

  • Loxoprofen-Na (sodium 2-〔4-(2-oxocyclopentylmethyl)pheny)propionate dihydrate) is a potent analgesic drug. We developed loxoprofen-Na plasters to extend duration time of analgesic activity and to reduce side effect on gastrointestinal tract. Analgesic effect of Loxoprofen-Na plasters was investigated. Loxoprofen-Na plaster had good analgesic effect in rat paw pressure test, Tail-flick latency test and acetic acid-induced writhing test. Also, it had anti-inflammatory effect on carrageenan-induced rat hind paw edema. In pharmacokinetic study of Loxoprofen-Na, plasters dosage form showed that plasma drug concentration was prolonged up to 14 hours. So, we can conclude that loxoprofen-Na plasters, when applied on skin, will be a new type of drug for controlling the various local pain or inflammation.
