In the present study, the anti-inflammatory effect of "Jungcheonhwadamgangki-tang ga Antler" water extract was tested in Xylene-Application mouse ear acute inflammation model. The test articles were once dosed before Xylene-Application, and the changes on body weight and ear weights and histopathological observation of induced ear were conducted with ear histomorphometry. The obtained results were as follows. The increases of absolute and relative ear weight detected in vehicle control compared to that of sham, were significantly and dose-dependently inhibited by Jungcheonhwadamgangki-tang ga Antler in the present study. A classic acute inflammatory histological changes such as subcutaneous edema, thickness and infiltration of inflammatory cells, was detected in vehicle control. However, these histological changes were significantly and dose-dependently inhibited by Jungcheonhwadamgangki-tang ga Antler. In addition, the increases of ear thickness half and thickness full detected in the vehicle control were also dose-dependently decreased in the all Jungcheonhwadamgangki-tang ga Antler-dosing groups. Base on these results, it is concluded that Jungcheonhwadamgangki-tang ga Antler extracts has clear anti-inflammatory effect on the acute inflammation such as bronchial asthma.

We investigated the effects of an ethanol extract from Perilla frutescens sprouts (PFSE) as an antioxidant, and its effects on edema and inflammation in RAW 264.7 cells and HMC-1 cells. The antioxidant activities (DPPH and ABTS radical scavenging) of PFSE were similar to those of butylated hydroxytoluene (BHT) and (${\pm}$)-6-hydroxy-2,5,7,8-tetramethylchromane-2-carboxylic acid (Trolox). We also investigated the anti-inflammatory effects of PFSE on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and HMC-1 cells stimulated with phorbol 12-myristate 13-acetate (PMA) with the calcium ionophore A23187. TNF-${\alpha}$ and IL-$1{\beta}$ production, which had been increased by treatment with LPS or PMA plus A23187, were significantly inhibited by PFSE in a dose-dependent manner. Furthermore, PFSE significantly reduced the xylene-induced ear edema and the carrageenan-induced paw edema of ICR mice in a dose-dependent manner. The effects of PFSE (200 mg/kg) in reducing ear and paw edema were similar to those of aspirin (50 mg/kg). These results suggest that PFSE can be potentially used as a medicine for treating oxidative stress, an edematous and inflammatory disease.

Background: Panax stipuleanatus represents a folk medicine for treatment of inflammation. However, lack of experimental data does not confirm its function. This article aims to investigate the analgesic and anti-inflammatory activities of triterpenoid saponins isolated from P. stipuleanatus. Methods: The chemical characterization of P. stipuleanatus allowed the identification and quantitation of two major compounds. Analgesic effects of triterpenoid saponins were evaluated in two models of thermal- and chemical-stimulated acute pain. Anti-inflammatory effects of triterpenoid saponins were also evaluated using four models of acetic acid-induced vascular permeability, xylene-induced ear edema, carrageenan-induced paw edema, and cotton pellet-induced granuloma in mice. Results: Two triterpenoid saponins of stipuleanosides R₁ (SP-R₁) and R₂ (SP-R₂) were isolated and identified from P. stipuleanatus. The results showed that SP-R₁ and SP-R₂ significantly increased the latency time to thermal pain in the hot plate test and reduced the writhing response in the acetic acid-induced writhing test. SP-R₁ and SP-R₂ caused a significant decrease in vascular permeability, ear edema, paw edema, and granuloma formation in inflammatory models. Further studies showed that the levels of inflammatory mediators, nitric oxide, malondialdehyde, tumor necrosis factor-α, and interleukin 6 in paw tissues were downregulated by SP-R₁ and SP-R₂. In addition, the rational harvest of three- to five-year-old P. stipuleanatus was preferable to obtain a higher level of triterpenoid saponins. SP-R₂ showed the highest content in P. stipuleanatus, which had potential as a chemical marker for quality control of P. stipuleanatus. Conclusion: This study provides important basic information about utilization of P. stipuleanatus resources for production of active triterpenoid saponins.

Onion (Allium cepa) is one of the flavonoids-rich materials in human diet and onion peel, which is the onion by-products, contains over 20 times more quercetin than the flesh. In this study, to examine the anti-inflammatory effects of onion peel hot water extract (OPHWE), the cell viability, nitric oxide (NO), pro-inflammatory cytokines, such as interluekin-6 (IL-6), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and IL-$1{\beta}$, were measured using the murine macrophage cell line RAW 264.7 cells. The Balb/c mice were used for an in vivo acute toxicity test and ICR mice were used for measurement of inhibition effects of croton oil-induced mouse ear edema. As a result, NO levels decreased in a dose-dependent manner. The production of IL-6, TNF-${\alpha}$, and IL-$1{\beta}$ was suppressed by 38%, 41%, and 34% respectively, compared with that of the LPS only group, without any cytotoxicity. The edema formation in the ICR mouse ear was also reduced compared to that in control. Moreover, there were no mortalities occurred in mice administered 5,000 mg/kg body weight of OPHWE. These results suggest that OPHWE has considerable anti-inflammatory activities and can be regarded as a potent candidate material to treat inflammatory diseases.

Porcine ear necrosis syndrome is characterized by erosive and ulcerative lesions at the margin or tip of the pinna. Three growing pigs of different ages exhibited retarded growth accompanied by reddening and necrosis of ear prior to death. Gross examination showed reddening, swelling, black discoloration, scaling, and variable-sized yellowish materials and edema in ear cross section. Microscopically, thrombosis, abscess, ulceration, epidermal hyperplasia, and dermal pyogranulomatous inflammation with an intralesional bacterial colony were observed. Staphylococcus hyicus was isolated in all pigs' ears and porcine reproductive and respiratory syndrome virus was detected by PCR and immunohistochemistry.

Contact dermatitis is induced by allergy response from a lot of chemical substances brought on by environmental contamination. In this study, we investigated allergy prevention effect of baicalein which is Scutellaria radix extract. Scutellaria radix is the dried roots of Scutellaria baicalensis Georgi (Labiatae). It has been used in oriental traditional medicine for treatment of fever, diarrhea and inflammation. We have induced allergy by PCL after oral administration of 0 mg/kg, 50 mg/kg or 100 mg/kg baicalein dose for 8 times during 8 days in BALB/c mice and measured ear thickness, IgE level, histamine level, mast cell number and histopathological changes. The ear thickness of the 100 mg/kg baicalein group was thinner than that of the 0 mg/kg baicalein group. IgE level and histamine level of the 100 mg/kg baicalein group were lower than those of 0 mg/kg baicalein group. The number of mast cells of 0 mg/kg baicalein group more than that of 100 mg/kg baicalein group in the ear tissue. In addition, intradermal edema with prominent inflammatory cell infiltration was observed at 0 mg/kg baicalein group more than 100 mg/kg baicalein group in the ear tissue. These results suggest that baicalein has allergy prevention effect in BALB/c mice.

The analgesic effects of DA-5018, a new caosaucin derivative, were evaluated in various experimental pain models. Drugs were administered subcutaneously or topically. When drugs were administered subcutaneously, 1) the $ED_{50}$ of DA-5018, morphine . HCI, capsaicin and acetaminophen were 0.091-2.0, 0.3-4.3, 1.4-26.5 and 45.4-643 mg/kg, respectively in various pain or inflammatory models including acetic acid writhing, formalin, tail flick, Randall-Selitto, hot plate and crouton oil-induced ear edema test, 2) the AD2 values (the dose for doubling of pain threshold of vehicle control) of DA-5018, capsaicin and ketoprpgin were 1.07 $\pm$ 0. 18, 23.47$\pm$4.46 and 2.97$\pm$0.43 mg/kg in Freund's complete adjuvant (FCA)-induced arthritic pain model. And by topical application, 1) neither DA-5018 0.3% cream nor Zostrix-HP (capsaicin 0.075%) were effective in formalin test, 2) although DA-5018 0.3% cream significantly inhibited the croton oil-induced ear edema being better than Zostrix-HP and Kenofen (ketoprofen 3%). 3) In FCA model, DA-5018 0.3% cream reversed the decreased pain threshold of arthritic rat from 136.4 g (day 0) to 289.0 g (day 5) and 250.1 g (day 10), which was similar to Zostrix-HP. These results suggest that DA-5018 administered subcutaneously has a potent and broad analgesic spectrum than nonsteroidal antiinflammatory drugs against acute and chronic pain, and by topical application it exerts comparable analgesic and antiinglammaatory effects to capsaicin cream.
