  • Oxidative rancidity in foods causes undesirable changes in nutritive value, aroma, flavor, and color. Salix Koreensis Andersson in DC. (SK) has anti-oxidative and anti-inflammatory effects and is traditionally used to treat neuralgia, edema, pain, and inflammatory diseases. However, the regulatory effects of SK on oxidative and inflammatory reactions have not been elucidated. In this context, we scientifically validated the anti-oxidative and anti-inflammatory activities of SK leaf (SKL). The methanol extract of SKL was evaluated for in vitro anti-oxidative activities. SKL showed increased superoxide dismutase (SOD)-like activity and 1, 1-diphenyl-2-picrylhydrazyl radical scavenging activity. The in vitro anti-oxidant and anti-inflammatory activities of SKL were also investigated in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. LPS resulted in decreased SOD activities compared with the unstimulated cells, but SKL significantly increased SOD activities reduced by LPS. In addition, LPS-induced nitric oxide, tumor necrosis factor-${\alpha}$, and interleukin-6 productions were significantly and dose-dependently reduced by SKL in RAW264.7 macrophages without inducing cytotoxicity. In conclusion, these results indicate that SKL will be able to be effectively used as a food additive with anti-oxidative and anti-inflammatory effects.

  • Red rose petals are usually disposed but they are an abundant source of phenolics and traditionally used as food supplement and as herbal medicine. Of the Various phenolics, they are known to have anticancer, antioxidant, and anti-inflammatory properties. In this study, we investigated the anti-inflammatory effects of red rose ethanolic extracts (GRP) on lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results demonstrated that pretreatment of GRP (500㎍/mL) significantly reduced NO production by suppressing iNOS protein expression in LPS-stimulated cells. Anti-inflammatory effects by red rose petals were observed in the following. Red rose petals inhibited the translocation of NF-κB from the cytosol to the nucleus via the suppression of IκB-α phosphorylation and also inhibited LPS-stimulated NF-κB transcriptional activity. These findings suggest that red rose petals exert anti-inflammatory actions and help to elucidate the mechanisms underlying the potential therapeutic values of red rose petals. Therefore, red rose petals could be regarded as a potential source of natural anti-inflammatory agents.

  • The aim of this study was to gain information on the effects of the crystal form of corticosteroids on the topical anti-inflammatory activity. Two different crystal forms, Form A and Form B, of the drugs of prednicarbate, hydrocortisone, betamethasone 17-valerate, prednisolone, and methyl prednisolone were prepared and their topical anti-inflammatory activities were measured using arachidonic acid induced ear edema assay in mice. Two crystal forms of the drugs showed differences in anti-inflammatory activity. Among the drugs examined, Form B of prednicarbate and betamethasone 17-valerate showed significantly more potent anti-inflammatory activities as compared to their Form A.

  • Previous screening of the pharmacological action of Gastrodia elata (GE) root (Orchidaceae) showed that methanol (MeOH) extracts have significant anti-inflammatory properties. The antiinflammatory agents of GE, however, remain unclear. In this experiment, MeOH extracts of GE were fractionated with organic solvents for the anti-inflammatory activity-guided separation of GE. Eight phenolic compounds from the ether (EtOEt) and ethyl acetate (EtOAc) fractions were isolated by column chromatography: 4-hydroxybenzaldehyde (I), 4-hydroxybenzyl alcohol (II), benzyl alcohol (III), bis-(4-hydroxyphenyl) methane (IV), 4(4'-hydroxybenzyloxy)benzyl-methylether (V), 4-hydroxy-3-methoxybenzyl alcohol (VI), 4-hydroxy-3-methoxybenzaldehyde (VII), and 4-hydroxy-3-methoxybenzoic acid (VIII). To investigate the anti-inflammatory and anti-oxidant activity of these compounds, their effects on carrageenan-induced paw edema, arachidonic acid (AA)-induced ear edema and analgesic activity in acetic acid (HAc)-induced writhing response were carried out in vivo; cyclooxygenase (COX) activity, reactive oxygen species (ROS) generation in rat basophilic leukemia (RBL 2H3) cells and 1,1-diphenyl-2-picryl-hydroazyl (DPPH) scavenging activity were determined in vitro. These phenolic compounds not only had anti-inflammatory and analgesic properties in vivo, but also inhibited COX activity and silica-induced ROS generation in a dose-dependent manner. Among these phenolic compounds, compound VII was the most potent anti-inflammatory and analgesic. Compound VII significantly inhibited silica-induced ROS generation and compound VI significantly increased DPPH radical scavenging activity. Compounds I, II and III significantly inhibited the activity of COX-I and II. These results indicate that phenolic compounds of GE are anti-inflammatory, which may be related to inhibition of COX activity and to anti-oxidant activity. Consideration of the structure-activity relationship of the phenolic derivatives from GE on the anti-inflammatory action revealed that both C-4 hydroxy and C-3 methoxy radicals of benzyl aldehyde play an important role in anti-inflammatory activities.

  • In oriental medicine, manual-acupuncture and electroacupuncture (EA) have been widely utilized to cure several inflammatory diseases such as arthritis. We designed this experiment to find neurochemical mechanism related to electroacupuncture induced anti-inflammatory effect on mouse air pouch model. EA with both low frequency (1 Hz) and high frequency (120 Hz) was treated after induction of inflammation in air pouch using injection of zymosan. To verify the role of opioid system in electroacupuncture-induced anti-inflammatory effect, naloxone (10 mg/kg) was pretreated. In addition, idazoxan (5 mg/kg) was pre-treated to evaluate the possible effect of endogenous adrenergic system in autonomic system on EA induced anti-inflammatory effect. As results of this study, naloxone pretreatment did not change the anti-inflammatory effect evoked by high frequency EA, while low frequency EA(1 Hz) induced anti-inflammatory effect was dramatically suppressed by naloxone pretreatment. These data indicated that endogenous opioid system might be extensively involve in anti-inflammatory effect evoked by not high frequency, but low frequency EA. However, idazoxan pretreatment did not produce any modulatory effect on both low and high frequency EA induced anti-inflammatory effect, suggesting that EA induced anti-inflammatory effect was not mediated by endogenous adrenergic system. In conclusion, these data strongly suggested that EA induced anti-inflammatory effect is mediated by endogenous opioid system, not endogenous adrenergic system.

  • The extract of Platycodi radix has long been used as an anti-inflammatory traditional medicine in Korea for the treatment of bronchitis, asthma and acute respiratory disease. In this study, the anti-inflammatory actions of the methanol extract of Platycodi radix administered via oral administration were evaluated. The results revealed that the extracts exhibited potent anti-inflammatory action. Of the hexane, chloroform, ethyl acetate, butanol and water fractions, the butanol fraction had the most potent anti-inflammatory action. Additioinally the sapogenin obtained through acid hydrolysis of the butanol fraction did not show anti-inflammatory action. These findings confirm the value of Platycodi radix as a traditional Korean medicine.

  • To investigate the therapeutic effect of a Korean herbal medicine Pulsatilla koreana as an anti-septic agent, anti-inflammatory effects of the herbal medicine were determined in lipopolysaccharide (LPS)-exposed rats. Treatment with a methanol extract from Pulsatilla koreana significantly inhibited LPS-induced inflammatory responses. Results from ELISA analysis showed that Pulsatilla koreana decreased the plasma and hepatic levels of pro-inflammatory cytokines such as IL-$1{\beta}$, IL-6, TNF-${\alpha}$ while increased the level of anti-inflammatory cytokine IL-10 in LPS-exposed rats. Pulsatilla koreana also decreased the plasma levels of other inflammatory mediators such as $NO_3{^-}/NO_2{^-}$, ICAM-1, $PGE_2$, and CINC-1 in LPS-exposed rats. Although no significant effects were observed in the phagocytic activities, the distribution of lymphocyte population was significantly shifted by the treatment with Pulsatilla koreana. All together, Pulsatilla koreana exerts anti-inflammatory activities in the immune-challenged animals implicating that this Korean herbal medicine is therapeutically useful for the treatment of inflammatory diseases like sepsis.

  • Several derivatives were synthesized from fructigenine A, which was isolated from Penicillium fructigenum. The anti-inflammatory properties of fructigenine A was evaluated in vivo with a 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced mouse ear edema model and a carrageenan-induced rat paw edema model. Results showed that the anti-inflammatory activity was significantly higher with fructigenine derivatives than with indomethacin, which was used as a standard. We concluded that fructigenine derivatives could exert an anti-inflammatory effect.

  • The anti-inflammatory effect of tuna heart water extract (THWE) was investigated using lipopolysaccharide-induced inflammatory response in this study. Anti-inflammatory effect was detected by the cell proliferation and the production levels of nitric oxide, pro-inflammatory cytokines such as interleukin-6 (IL-6), IL-$1{\beta}$, and tumor necrosis factor-alpha. As a result, there were no cytotoxic effects on proliferation of macrophages treated with THWE compared to the control. The production of pro-inflammatory cytokines was remarkably suppressed compared with that of the LPS only group. These results suggest that THWE exerts the anti-inflammatory property by inhibiting production of inflammatory factors and may be a potential material for anti-inflammatory therapy.
