Background and Object : This study was carried out to investigate the effects of GCSBPT (Gagam-Cheongsang BangPungTang) on the in vitro and in vivo anti-inflammatory reactions. Methods : Vascular permeability and Cyclooxygenase inhibition assay are examined in vitro and nitric oxide inhibition assay, radical scavenging activity test, $TNF-{\alpha}$, COX-2 inhibition test are examined in vivo. Results : GCSBPT showed inhibitory effects on vascular permeability and leukocyte migration in animal test. In cyclooxygenase 2 inhibition assay, an ethanol extract of GCSBPT inhibited prostaglandin E2 generation at a concentration of $10{\mu}g/ml$. Among the herbal ingredients of GCSBPT, ethanol extracts of Nepetae Spica exhibited potent inhibitory activities. Ethanol extract of GCSBPT inhibited the release of nitric oxide and the gene expression of inducible nitric oxide synthase in RAW 246.7 cells stimulated by lipopolysaccharide. Ethanol extract of GCSBPT exhibited radical scavenging activity of 54% at $100{\mu}g/ml$. Among the herbal ingredients of GCSBPT. Conclusions : According to the above results, I expected that GCSBPT was a potent anti-inflammatory prescription.

Oxidative stress has been reported to be one of causes of neuritis. This study examined antioxidative activities of methanol extracts of six amphibian species known to be medicinal animals (Rana catesbeiana, R. coreana, R. rugosa, R. dybowskii, R. nigromaculata, and Hyla japonica) and investigated their effects of inhibiting nitric oxide (NO) production and cytotoxicity on the murine macrophage RAW264.7 cells. As inflammation is closely associated with reactive oxygen species, assays on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, xanthine oxidase inhibitory activity, superoxide anion radical scavenging activity and NO scavenging activity of the extracts of the six species were performed to investigate their antioxidative activity. The results obtained were as follows; All extracts showed antioxidative activity, and the activity of R. dybowskii was the highest in comparison among those. Anti-inflammatory effects of the extracts were also examined, the five extracts except that of R. rugosa did not show cytotoxicity for RAW264.7 cells at the maximal concentration ($1,000{\mu}g\;mL^{-1}$). Selectivity index, meaning NO scavenging activity compared to cytotoxicity, showed the highest level in the extract of R. dybowskii. These results will be very useful basic data for future studies on prevention and treatment of human diseases to understand the biological roles of amphibian extracts throughout the antioxidative or anti-inflammatory pathways.

This study aimed to assess fatty acid composition and anti-inflammatory effects, such as nitric oxide(NO) production, expression of $TNF-{\alpha}$ and interleukin-6(IL-6), of Tenebrio molitor larva using RAW 264.7 cells. The content of total fatty acid in Tenebrio molitor larva was 76.14%, which was composed of oleic acid(42.12%), linoleic acid(32.67%) etc. There was no cytotoxicity at a dose level of 0.1, 1.0, 10, and $100{\mu}g/mL$ of freeze dried Tenebrio molitor larva ethanol extract(FDTEtOH) on RAW 264.7 cells. FDTEtOH significantly decreased NO production in LPS(lipopolysaccharide)-stimulated RAW 264.7 cells in a dose-dependent manner. Also, FDTEtOH dose-dependently suppressed the expression of $TNF-{\alpha}$ and IL-6. Thus, these results showed that Tenebrio molitor larva has the potential to be used as an anti-inflammatory food to improve immunity.

The rhizome of Cibotium barometz has been used for variety of bone disease as a traditional medicine. In the present study, we examined the antioxidant and anti-inflammatory activities of 85% methanol extract of C. barometz. C. barometz exhibited potent scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, superoxide radical and nitric oxide radical. In IFN-$\gamma$/LPS-stimulated mouse peritoneal macrophage model, C. barometz suppressed nitric oxide production and IL-6 secretion dose-dependently. Moreover, C. barometz showed decreased iNOS and COX-2 expression without notable cytotoxicity. These results suggest that C. barometz may be an useful agent as an antioxidant and anti-inflammatory agent.

Peptidoglycan in inserts and mammals is well known to improve biological functions in the host's immune system. However, it is unclear how Peptidoglycan exerted its anti-inflammatory capacity especially in clam worm (Marphysa sanguinea). In this experiment, the anti-inflammatory and antioxidant effects of clam worm extract treated with (PCWE) peptidoglycan (Micrococcus luteus) in RAW264.7 cells were examined by measuring MDA, catalase, SOD, GSH-Px and inflammatory cytokines (nitric oxide, iNOS, interleukin-$1{\beta}$ and tumor necrosis factor-${\alpha}$). PCWE significantly increased the activities of catalase, SOD and GSH-Px and decreased the level of MDA. Interestingly, PCWE induced activities of SOD and GSH-Px more than clam worm extract without peptidoglycan (CWE). In addition, PCWE decreased NO production, iNOS, COX-2, TNF-${\alpha}$ and IL-$1{\beta}$ better than CWE. Taken together, these results indicate that PCWE has the potential as a natural antioxidant and a therapeutic for inflammation-related diseases.

Objective : This study was designed to investigate the anti-inflammatory effect of Scolopendrid Herbal-Acupuncture. Methods : Scolopendrid Herbal-Acupuncture was administered one time on everyday and A-shi points were selected. Except Scolopendrid Herbal-Acupuncture administration, other therapies(conventional body acupuncture, physical therapy and so on) were not performed at all. We evaluated the patient through Visual Analogue Scale(VAS) and Digital Infrared Thermal Imaging(DITI). Results : After 2 or 3 times of treatment, the patient showed that clinical symptoms and VAS were lessened and there was a change of temperature in DITI. Conclusions : According to the results, Scolopendrid Herbal-Acupuncture may have anti-inflammatory effects. But further studies are required to prove the exact effect.

With extracted Aloe vera and Aloe arborescens, anti-inflammatory effect was examined in phosphatidic acid-stimulated Raw 264.7 cells. Phosphatidic acid $(50\;{\mu}g/ml)$ treatment increased inflammation related 264.7 cells. The extracts of $80\;{\mu}g/ml$ concentration from Aloe arborescens reduced the expression of iNOS. Aloe vera and Aloe arborescens also reduced the expression of COX-2, it seems that anti-inflammatory effects of Aloe extracts is partly due to the inhibition of COX-2 expression by inhibiting in Raw 264.7 cells.

This study was conducted to examine the bleaching of an anti-inflammatory agent containing Undaria pinnatifida extract (AIAU). Brown-colored AIAU was irradiated with $^{60}CO$ gamma rays at doses ranging from 10-200 kGy. Discoloring of the anti-inflammatory agent was achieved by gamma irradiation, with significantly removal by 50 kGy irradiation. The main active compound of the agent consisted of 4% U. pinnatifida extract, which inhibited inflammatory symptoms in mouse ear edema by 93%. There was no change in effects against edema, erythema, blood flow and radical scavenging activity by irradiation.

Quercetin-3-O-${\beta}$-D-glucuronopyranoside (QGC) is a flavonoid glucoside extracted from Rumex Aquaticus Herba. In the present study, anti-oxidative and anti-inflammatory effects of QGC were tested in vitro. Epithelial cells obtained from cat esophagus were cultured. When the cells were exposed to acid for 2 h, cell viability was decreased to 36%. Pretreatment with 50 ${\mu}M$ QGC for 2 h prevented the reduction in cell viability. QGC also inhibited the productions of intracellular ROS by inflammatory inducers such as acid, lipopolysaccharide, indomethacin and ethanol. QGC significantly increased the activities of superoxide dismutase (SOD) and catalase, and also induced the expression of SOD2, while it restored the decrease of catalase expression in cells exposed to acid. QGC inhibited NF-${\kappa}B$ translocation, cyclooxygenase-2 expression and $PGE_2$ secretion in cells exposed to acid, which plays an important role in the pathogenesis of esophagitis. The data suggest that QGC may well be one of the promising substances to attenuate oxidative epithelial cell injury and inflammatory signaling in esophagus inflammation.

The hawthorn fruit (Crataegus pinnatifida Bunge var. typica Schneider) is used as a traditional medicine in Korea. The objective of this study was to understand the mechanisms of the anti-inflammatory effects of the water fractionated portion of hawthorn fruit on a lipopolysaccharide (LPS)-stimulated RAW 264.7 cellular model. The level of nitric oxide (NO) production in the water fraction and LPS-treated RAW 264.7 cells were determined with an ELISA. The cytotoxicity of the water fraction and LPS was measured with an MTT assay. Expression of nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor (TNF)-${\alpha}$, interleukin 6 (IL-6), and interleukin $1{\beta}$ (IL-$1{\beta}$) mRNA were analyzed with a reverse transcription polymerase chain reaction (RT-PCR). The water fraction of hawthorn fruit was determined to be safe and significantly inhibited NO production in LPS-stimulated RAW 264.7 cells and suppressed COX-2, (TNF)-${\alpha}$, IL-$1{\beta}$, and IL-6 expression. The observed anti-inflammatory effects of the water fraction of hawthorn fruit might be attributed to the down-regulation of COX-2, (TNF)-${\alpha}$, IL-$1{\beta}$, and IL-6 expression in LPS-stimulated RAW 264.7 cells.
