  • 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.

  • Earthing, caused by direct skin contact with the Earth's surface, is used to reduce the symptoms of inflammation (fever, fever, swelling and pain). However, there is little evidence to support the anti-inflammatory effects of earthing mattresses. Therefore, this study was conducted to investigate whether anti-inflammatory effect of earthing mattress using an in vivo animal model. The anti - inflammatory effect was evaluated by measuring ear thickness and foot volume in 12-O-tetradecanoylphorbol-13 acetate (TPA) - induced ear edema and carrageenan - induced paw edema model, respectively. Balb/c mouse in carrageenan paw edema model showed significant anti - inflammatory effect in the group treated with earthing mattress for 4 hours or 24 hours for 3 days. For females, the anti-inflammatory effect was greater when the earthing mattress was added to the mattress than the mattress alone treatment. From the above results, it was found that the female responds more to the effect of the earthing as well as the mattress effect. In addition, when the male and female Balb/c mice were exposed to mattresses and earthing mattresses for 24 h for 3 days, respectively, the mattress and earthing mattresses showed significant inhibition of IL (Interleukin)-1β levels compared to the control. In the TPA ear edema model, Balb/c mouse showed significant anti - inflammatory effect in the group treated with the earthing mattress for 4 hours or 24 hours for 3 days. Both males and females showed more anti-inflammatory effects when they were exposed to earthing mattresses with mattresses added to the mattresses. From the above results, it was found that both male and female respond to the effect of earthing as well as the mattress effect in the TPA ear edema model. In conclusion, in this study, we have verified that earthing mattress shows inhibitory effects on TPA and carrageenan-induced inflammation. From these results, it is suggested that the anti-inflammatory effect can be expected by applying the earthing mattress to patients suffering from inflammatory diseases. However, there is a need to pinpoint exactly how the earthing mattress relieves inflammation, and further research is needed to investigate the mechanism.

  • Dichloromethane, ethanol, and boiling water extracts of the brown alga Ecklonia cava were examined in vivo for their antipyretic, analgesic, and anti-inflammatory activities in mice. These activities were evaluated by yeast-induced pyrexia, tail-flick test, and phorbol myristate acetate-induced inflammation (edema, erythema, and blood flow). Ethanol extract of E. cava (0.4 mg/ear) inhibited the inflammatory symptoms of mouse ear edema, erythema, and blood flow by 82.6%, 69.0%, and 65.4%, respectively. This extract also demonstrated potent analgesic activity. No acute toxicity was observed after p.o. administration of each extract (5 g/kg bw). These in vivo data are in agreement with the claims of the health care industry and indigenous medicine that E. cava is an effective remedy for inflammation-related symptoms.

  • Elsholtzia splendens Nakai has been used in North-East Asia as an ingredient of folk medicines for treating cough, headache and inflammation. The present investigation was carried out to establish its in vivo anti-inflammatory activity using several animal models of inflammation and pain. The 75% ethanol extract of the aerial part of E. splendens significantly inhibited mouse croton oil-induced, as well as arachidonic acid-induced, ear edema by oral administration (44.6% inhibition of croton oil-induced edema at 400 mg/kg). This plant material also showed significant inhibitory activity against the mouse ear edema induced by multiple treatment of phorbol ester for 3 days, which is an animal model of subchronic inflammation. In addition, E. splendens exhibited significant analgesic activity against mouse acetic acid-induced writhing (50% inhibition at 400 mg/kg), while indomethacin (5 mg/kg) demonstrated 95% inhibition. E. splendens ($5-100{\;}{\mu}g/mL$) significantly inhibited $PGE_2$ production by pre-induced cyclooxygenase-2 of lipopolysaccharide-treated RAW 264.7 cells, suggesting that cyclooxygenase-2 inhibition might be one of the cellular mechanisms of anti-inflammation.

  • The anti-inflammatory effects of Sargassum micracanthum ethanol extract (SMEE) was investigated using LPS-induced inflammatory response in this study. As a result, there was no cytotoxicity in the macrophage proliferation treated with SMEE compared with the control. SMEE inhibited production of nitric oxide and cytokines (IL-6, TNF-${\alpha}$, and IL-$1{\beta}$) in a dose-dependent manner. In addition, the expression of inducible nitric oxide synthase and cyclooxygenase 2 were suppressed via inhibition of nuclear factor ${\kappa}B$ p65 expression by SMEE treatment. The formation of edema in the mouse ear was reduced at the highest dose tested compared with that in the control, and reduction of ear thickness was observed in histological analysis. Moreover, in an acute toxicity test, no mortalities occurred in mice administered 5,000 mg/kg body weight of SMEE over a 2-week observation period. These results suggest that SMEE may have significant effects on inflammatory mediators and be a potential anti-inflammatory therapeutic material.

  • Anti-inflammatory effects of turmeric (Curcuma longa L.) rich in polysaccharides, as well as free of curcuminoids and turmerones were investigated in acute and chronic inflammatory models. Activity against the acute phase of inflammation was evaluated in carrageenan-induced paw edema and xylene-induced ear edema models. The results showed that turmeric extract significantly decreased paw edema volume in the first and third hours after carrageenan injection ($P{\leq}0.05$). Turmeric extract at all dose levels also significantly inhibited xylene-induced ear edema formation ($P{\leq}0.05$). Activity against chronic inflammation was also evaluated in cotton pellet-induced granuloma model. Turmeric extract significantly ($P{\leq}0.05$) decreased the weight of granuloma tissue on cotton pellets in a dose-dependent manner when compared to the vehicle control. Thus, the findings of the study suggest that turmeric extract in effective against both acute and chronic inflammation.

  • Purpose: This work aimed to elucidate the anti-inflammatory effect of pegmatite in vitro and in vivo. Methods: Author evaluated the suppressive effects of pegmatite on lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production, TNF-${\alpha}$ and IL-6 release in the RAW 264.7 murinemacrophages. Results: Treatment of RAW 264.7 cells with pegmatite significantly reduced LPS-stimulated NO production and inflammatory cytokine such as TNF-${\alpha}$ and IL-6 secretion in a concentration-dependent manner. Also pegmatite showed topical anti-inflammatory activity in the arachidonic acid (AA)-induced ear edema and acetic acid-induced increase in capillary permeability assessment in mice. It was also found that pegmatite (10 mg per ear in DW) inhibited arachidonic acid induced edema at 24 h more profoundly than 1 h by topical application. Furthermore, the vascular permeability increase induced by acetic acid was significantly reduced in mice that received pegmatite in 50 mg per mouse. Conclusion: Therefore the results of the present study suggest that pegmatite is a potent inhibitor of the LPS-induced NO and inflammatory cytokine in RAW 264.7 macrophages and showed anti-inflammatory activities in vivo animal model.

  • Most inflammatory disorders are usually treated using anti-inflammatory drugs including non-steroidal anti-inflammatory drugs (NSAID) and steroidal anti-inflammatory drugs (SAID). In a prolonged use, however, they may frequently produce adverse side-effects. Thus, it is necessarily required to develop a new anti-inflammatory drug with little side-effects. Nephrite has been widely used by traditional oriental medicine to cure the various chronic diseases. In order to verify the anti-inflammatory activity of nephrite, the TPA (12-O-tetradecanoylphorbol-acetate) or the croton oil-induced edema was developed in the mouse ears and the nephrite powder suspension or the nephrite water was directly applied to the ear edema. It was found that nephrite could significantly reduce the ear swelling implying its strong potential as an active anti-inflammatory agent when comparing to indomethacin, a non-steroidal anti-inflammatory drug.

  • Objectives : The present study investigated the anti-nociceptive and anti-inflammatory properties of the water extract of Geranii Herba (The stem and leaves of Geranium thunbergii Sieb. et Zucc.) in the animal models of pain and inflammation. Methods : We evaluated the anti-nociceptive and anti-inflammatory activities of Geranii Herba extract (GHE) using the writhing test, tail-flick test, carrageenan-induced paw edema and xylene-induced ear edema models. Two dose of GHE (100 and 1000 mg/kg) was administrated orally to the mice. Control group received normal saline and ibuprofen (50 mg/kg) was used as a positive control drug. Results : GHE 1000 mg/kg treated group showed an increased tail-flick response time in the tail-flick test and inhibitory effect on writhing syndrome induced by acetic acid. Treatment with GHE at the same dose inhibited ear edema induced by xylene and foot edema induced by carrageenan toxicity. Conclusion : The results demonstrate that GHE has anti-nociceptive and anti-inflammatory effects in the various models of nociception and inflammation.

  • Background and objective: Dermatitis is a chronic disease accompanied by such symptoms as itching and dry skin. The environment and diet can aggravate dermatitis, so attention to skin care is essential. Colocasia esculenta is used in various manners and for different purposes, including with regard to inflammation, aging, and the digestive system. The anti-inflammatory effect of Colocasia esculenta water extract was confirmed using RAW 264.7 macrophages with regard to male ICR mice. Methods: In the case of the ICR mice, 5% 12-O-Tetradecanoylphorbol-13-acetate (TPA) was used to cause inflammation for 7 days, and 100 μL of Colocasia esculenta water extract and panthenol were administered orally for 10 days. In addition, RT-PCR, NO, ELISA was conducted. Results: As a result of reverse transcription polymerase chain reaction (RT-PCR) using RAW 264.7 macrophages stimulated with lipopolysaccharide (LPS), it was found that Colocasia esculenta water extract reduced the expression of inflammatory cytokines. As a result of hematoxylin and eosin (H&E) staining using mouse ear tissue, Colocasia esculenta water extract reduced ear thickness and showed an effect of suppressing ear edema. In addition, compared to the TPA-treated group, the Colocasia esculenta extract-treated group had reduced nitric oxide (NO) production by 18.23 μM and IL-13 production decreased by 136.55 pg/ml. Conclusion: Colocasia esculenta water extract has been shown to be effective in lowering inflammatory cytokine production. These results suggest that Colocasia esculenta water extracts can be used as natural products to treat dermatitis.
