Background: Angelica dahurica has been used in various clinical cases. Its taste is hot and its property is warm, dry and nonpoisonous. Its efficacy is to remove wind-damp, cure swelling and edema, exhaust pus, stop itching, rhinitis and leukorrhea. Object: To test through experiment Angelica dahurica's analgesic and anti-inflammatory efficacy. Method: Inject acetic acid as a pain-inducing substance to the mice and measure visceral pain bywrithing reflex. Inject carrageenan that is an edema-inducing substance to the rat's paw and measure volume of edema. Take thermal pain to mice with plantar test and measure paw withdrawal latency. Normal group is non Angelica dahurica-treated group and treated group is Angelica dahurica-treated group. Results: In acetic acid-induced visceral model, treatment with Angelica dahurica suppressed writhing reflex significantlyand dose-dependently. In carrageenan-induced paw edema model, treatment with Angelica dahurica suppressed carrageenan-induced paw edema. In plantar test model, no significant effect on the withdrawal latency of thermal stimulation-induced nociception was observed. Conclusion: Angelica dahurica has analgesic and anti-inflammatory efficacy.

Objective : The aim of this study is to investigate the anti-inflammatory effects of 15Hz electroacupuncture(EA) on carrageenan-injected rats. Inflammation was induced by an intraplantar injection of 1% carrageenan into the right hind paw. Methods : Bilateral EA stimulation with 15 Hz were delivered at those acupoints corresponding to Zusanli and Sanyinjiao in man via the needles for a total of 30 min duration in carrageenan-injected rats. Results: The developing edema was measured 30 minutes interval afer carrageenan injection and 15 Hz EA stimulation presented significant edema inhibition. Three hours after carrageenan injection, prostaglandin $E_2(PGE_2)$ and nitric oxide(NO) levels were measured. The 15Hz EA stimulation significantly inhibited $PGE_2$ and NO production in the right paw. The pro-inflammatory mRNA expression such as cyclooxygenases(COX)-2 and interleukin(IL)-$1{\beta}$ were slightly down-regulated by EA stimulation. The number of COX-2, IL-$1{\beta}$, tumor necrosis factor-${\alpha}$ immunoreactive cells were abundantly observed in paw edema. But these cells were decreased in nmber according to anti-edema effect of 15Hz EA. Conclusions: These results indicate that 15Hz EA stimulation have an alleviation action against carrageenan-induced edema and local inflammation.

Potentilla chinensis Ser. (Rosaceae) has long been used for a remedy of diarrhea and inflammation in Korea. In this study, the anti-inflammatory effects of the Potentillae chinensis Herba water extract (PCX) was investigated in proteinase-activated receptor-2 (PAR2)-mediated rat paw edema. Paw edema was induced by injection of trypsin or trans-cinnamoyl-LIGRLO-$NH_2$ (tc-$NH_2$) into the hind paw of rats. PCX (10, 50, 100 and 200 mg/kg) was orally administered 1 h before the induction of inflammation. At doses of 50, 100 and 200 mg/kg, PCX showed significant inhibition on both change in paw volume and vascular permeability. PCX (100 mg/kg) significantly inhibited PAR2 agonists-induced myeloperoxidase (MPO) activity in paw tissue. These results indicate that PCX has an anti-inflammatory action in PAR2-mediated paw edema.

The anti-inflammatory activity of SEO-KYONG-TANG extract(SKTWE) was examined by using 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 SKTWE were investigated by using general experimental methods in mice. SKTWE did not show acute toxicity at 2400 mg/kg(p.o.) nor 1200 mg/kg(i.p.). After oral administration of the SKTWE to rats, significant anti-inflammatory activity was observed on 1% carrageenin- and 5% acetic acid-induced edema. Also, it significantly inhibited granuloma and exudation in these. In the adjuvant arthritis experiment, the SKTWE decreased the hind paw edema after 3 days of oral administration. In addition, it inhibited the writhing syndromes induced by 0.7% acetic acid in mice. The antipyretic activity of SKTWE was also observed through the typhoid vaccine experiment. These results suggest that SKTWE has analgesic, anti-inflammatory and antipyretic action.

Cactus (Opuntia ficus-indica var saboten Makino) is a tropical or subtropical plant, which is widely used as folk medicine for burned wound, edema and indigestion. We previously found that the ethanol extract of cactus stem showed anti-inflanunatory action. This investigation was designed to isolate the active fraction of anti-inflanimatory action from cactus stem by solvent extraction and colunm chromatography. Carrageenan-induced paw edema in rats and acetic acid-induced writhing test in mice were used as animal models to search anti-inflammatory and analgesic activities. respectively. The ethanol extract of cactus stem was consecutively extracted with hexane, ethyl acetate, and n-butanol. The hexane fraction was the most effective in carrageenan-induced paw edema, and then was separated in colunm chromatography of silica gel by the elution with hexane/ethyl acetate mixture. The most effective fraction 1 was separated in a second colunm chromatography by eluting with hexane/diethyl ether mixture. The most effective fraction 1-5 was obtained, and separated in a third column chromatography by eluting with hexane/chloroform mixture. It produced the most effective fraction 1-5-1. Moreover, fraction 1-5-1 showed an inhibitory effect on acetic acid-induced writhing in the doses of 30mg/kg and 60mg/kg,p.o.,indicating that it also contained analgesic activity.

In order to examine the anti-ohyul (anti-inflammatory) activity of rhubarb, we investigated the effects of stilbene derivatives obtained from rhizomes of Rheum undulatum on the carrageenan-induced hind paw edema in rats. Administration of stilbene aglycon (rhapontigenin) at doses of 50 and 100 mg/kg exhibited the anti- edema effect in dose dependent manner and stilbene glycosides $(rhaponticin,\;piceatannol-3'-O-{\beta}-D-glucopyranoside)$ at a dose of 100 mg/kg also showed inhibitory effect on the carrageenan-induced edema. These inhibitory effects may ascribed, at least in part, to the anti-ohyul activity of rhubarb.
