Background: Danggwisusan is a herbal medicine which is used to treat bruises, static blood, external injuries, and somatalgia in Korean medicine. The objectives of this study were to investigate whether Danggwisusan hot aqueous extract had an inhibitory effect upon inflammatory cytokine production and oxidation. Methods: Cytotoxic activity of Danggwisusan extract was examined by 3-(4,5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay. The amount of nitric oxide produced was measured using Griess reagent. Prostaglandin E2 production was measured using an enzyme immunoassay. Inflammatory cytokines ($IL-1{\beta}$, IL-6 and $TNF-{\alpha}$) were measured by an enzyme linked immunosorbent assay. The anti-oxidative effect of Danggwisusan was measured by the 1,1-Diphenyl-2-picryl hydrazyl method. The amount of polyphenol and flavonoid contents were measured by Folin and Ciocalteauea phenol reagent and aluminum nitrate. Results: Danggwisusan hot aqueous extracts did not show significant toxicity at 10, 20, 50, and $100{\mu}g/mL$. At a dose of $100{\mu}g/mL$, Danggwisusan hot aqueous extract significantly inhibited nitric oxide and $PGE_2$ production, and significantly reduced $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production. At a dose of $100{\mu}g/mL$, 1,1-Diphenyl-2-picryl hydrazyl free radical scavenging capability was over 50%. Conclusion: This study showed that Danggwisusan hot aqueous extract may have anti-inflammatory and anti-oxidative effects on macrophages.

Inflammatory mediators such as interleukin-1 (IL-1), tumor necrosis $factor-{\alpha}\;(TNF-{\alpha}),\;interferon-{\gamma}\;(IFN-{\gamma})$ and lipopolysaccharide (LPS) are thought to play major roles in joint diseases such as a rheumatoid arthritis (RA), and there is considerable evidence playing a role for these cytokines in osteoarthritis (OA). Therefore, we have studied the effects on anti-inflammation and analgesic by ethyl acetate fraction from 70% ethanol extract of Artemisia capillaries (EAC). As a positive control, apigenin, which is known as an anti-inflammatory agent as an iNOS inhibitor, was used and showed the dose-dependent inhibitory effect. EAC showed strong inhibitory efficacy against cytokine-induced proteoglycan degradation, $PGE_2$ production, nitric oxide (NO) production, and matrix-matalloproteinases (MMPs) expression in rabbit articular chondrocyte. In the writhing test induced by acetic acid, EAC $(200{\sim}400\;mg/kg)$ exhibited a dose-dependent inhibition of writhing. The results indicate that EAC have anti-inflammatory and analgesic activities, and could be a good herbal medicine candidate for curing of RA and/or OA.

The anti-inflammatory activity of water extract of Mahaengeuigam-Tang(MHEGTWE) was examined using the carrageenin and acetic acid induced edema, croton oil induced granuloma pouch, and adjuvant arthritis in rats. In addition, the acute toxicity, analgesic and antipyretic effects of MHEGTWE were investigated by the general experimental methods. In acute toxicity test in mice, MHEGTWE showed 10% mortality at 2400 mg/kg(p.o), but it did not showed at 1200 mg/kg(i.p). It was also showed significant analgesic action on the writhing syndrome induced by 0.7% acetic acid at 600 mg/kg(p.o) and its antipyretic activity was observed in the typhoid vaccine induced fevered rats at 300 mg/kg(p.o). By the oral administration of the MHEGTWE, the significant anti-inflammatory activity was observed on 1% carrageenin induced edema, and it significantly inhibited the granuloma and exudate formation in rats. In the adjuvant arthritis experiment, the MHEGTWE decreased the hind paw edema in rats for 19 days. The results suggest that MHEGTWE has analgesic, anti-inflammatory and antipyretic action.

This study was performed that how phonophoresis using ultrasound for piroxicam affects transdermal permeation and anti-inflammative effects. Transdermal permeation study conducted by using hairless mouse had two categories: control group and ultrasound group. Transdermal permeation was observed according to duty cycle and intensity. Anti-inflammatory effects were determined using in Sprague-Dawley rat. The subjects were divided into three groups of six SD rat each 24 hour, 48 hour, 72 hour. The results of this study were as follows: 1. Transdermal permeation of piroxicam was measured according to ultrasound duty cycle. This research demonstrates that ultrasound group retains more transdermal permeation than control group, and that pulsed ultrasound group holds a little more transdermal permeation than continuous ultrasound group. 2. The transdermal permeation of piroxicam is closely related with ultrasound intensity. Effect of each group of transdermal permeation was significant rises in proportion to ultrasound intensity. 3. By observing inflammation of the tissue caused by trauma, phonophoresis group showed more significant of anti-inflammatory effect. The conclusion of phonophoresis was found to improve significantly the transdermal permeation and the anti-inflammatory effect.

Objectives : Consumption of fermented foods has been known to alleviate some of the symptoms of atopy and may limit allergy development, while there are also many medicinal herbs proved to be effective for immunologically-mediated diseases. In this study, we introduced modern zymology to ferment some herbs to see if fermentation has the possibility of increasing the anti-inflammatory effects of medicinal herbs. Interleukin-4 (IL-4) and interferon-gamma $(INF-\gamma)$ have been demonstrated to be the main factors in the pathology of allergic diseases. Methods : We measured the levels of IL-4 and $INF-\gamma$ on concanavalin A-induced BALB/c mice spleen cells, which were subsequently treated with fermented and unfermented herbs. We then compared the fermented groups with unfermented groups to see if the anti-inflammatory effects of the herbs were influenced by fermentation. Results and Conclusions : Our results showed that fermentation had the potential to increase the anti-inflammatory effects of some medicinal herbs, and Astragalus membranaceus and Salvia miltiorrhiza would be the most suitable medicinal herbs for fermentation among the herbs in this study.

Enrofloxacin, a fluoroquinolone, is a broad-spectrum antibiotic widely used in veterinary medicine that inhibits the action of bacterial DNA gyrase, resulting in anti-bacterial effects. This study was performed to examine whether enrofloxacin has modulatory and anti-inflammatory activity on immune cells. A few studies have reported the anti-inflammatory effects of enrofloxacin. In this study, we used mouse spleen cells treated with lipopolysaccharide (LPS) and examined the effects of enrofloxacin. Several assays were performed in LPS-treated spleen cells after the enrofloxacin treatment. Enrofloxacin inhibited the metabolic activity and mitochondrial membrane potential of LPS-treated spleen cells significantly. On the other hand, enrofloxacin did not alter the proportion of the subsets in spleen cells, and did not induce cell death. The production of tumor necrosis factor-alpha in LPS-treated spleen cells was inhibited by enrofloxacin. Overall, enrofloxacin had modulatory activity in spleen cells treated with LPS. These data may broaden the use of enrofloxacin as an antibiotic with anti-inflammatory activity in veterinary clinics.

Platycodon grandiflorum (balloon flower) root (Platycodi radix, PR) is used as a health supplement owing to its beneficial bioactive properties. In the present study, the anti-inflammatory, antioxidant, and whitening effects of deglycosylated platycosides (saponins) from PR biotransformed by pectinase from Aspergillus aculeatus were investigated. The bioactivities of the platycosides improved when the number of sugar moieties attached to the aglycone platycosides was decreased. The deglycosylated saponins exhibited higher lipoxygenase inhibitory activities (anti-inflammatory activities) than the precursor platycosides and the anti-inflammatory compound baicalein. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of the pectinasetreated PR extract was higher than that of the non-treated PR extract. The trolox-equivalent antioxidant capacity (TEAC) assay showed improved values as the saponins were hydrolyzed. The tyrosinase inhibitory activities (whitening effects) of deglycosylated platycosides were higher than those of the precursor platycosides. Furthermore, 3-O-β-ᴅ-glucopyranosyl platycosides showed higher anti-inflammatory, antioxidant, and whitening activities than their precursor glycosylated platycosides. Therefore, 3-O-β-ᴅ-glucopyranosyl platycosides may improve the beneficial effects of nutritional supplements and cosmetic products.

Lyophyllum decastes has been used for culinary purpose. The present study was conducted to evaluate the antioxidant and anti-inflammatory effects from methanol, acetone, and hot water extracts of L. decastes fruiting bodies. The acetone and methanol extracts showed the higher 1,1-diphenyl-2-picryl-hydrazy radical scavenging activities than that of the hot water extract at 0.5-2.0 mg/mL and was comparable to the BHT, the positive control. The ferrous ion chelating effects of the mushroom extracts at 0.5-2.0 mg/mL were significantly higher than that of BHT. The reducing power of acetone extract (2.12) was significantly lower than that of BHT (2.73) at 2.0 mg/ mL. The mushroom extracts also showed inhibitory effects on production of nitric oxide (NO), and expression of inducible nitric oxide synthase (iNOS) in lipopolysaccharide-induced murine macrophage cells in a concentration dependent manner. In vivo anti-inflammatory experiment on carrageenan-induced hind-paw edema of rat model, the acetone extract of the mushroom significantly suppressed the carrageenan-induced rat hind paw edema of rats in a dose dependently. The results suggest that the fruiting bodies of Lyophyllum decastes are a good natural resource of antioxidant and anti-inflammation.
