Introduction : In this study, the analgesic effect and its mechanism of bee venom aqua-acupuncture on complete Freund's adjuvant-induced arthritis in rats was investigated. It has been reported from a neurochemical standpoint that bee venom exerts antinociceptive effects on inflammation and that the opioid system and adrenergic system play important roles in acupuncture analgesia. however, it is not known whether central opioid and ${\alpha}2$-adrenergic components of the intrinsic descending analgesic system are activated after bee venom aqua-acupuncture. Methods : Bee venom(1mg/kg) was subcutaneously aqua-acupunctured into Joksamni($ST_{36}$) of rats with complete Freund's adjuvant(CFA)- induced arthritis and was checked of increase in TFL. Opioid and ${\alpha}_2$-adrenergic neurotransmitter system were examined by naloxone as an opioid receptor antagonist, and yohimbine as ${\alpha}_2$-adrenoceptor antagonist prior to bee venom aqua-acupuncture. Results : The following results have been obtained. 1. The tail flick latency in the rat model with adjuvant-induced arthritis was significantly decreased in 2 weeks. 2. The tail flick latency in the rat model with adjuvant-induced arthritis was increased in bee venom aqua-acupuncture group compared to the normal saline aqua-acupuncture group. 3. Analgesic effect of bee venom was antagonized by yohimbine not by naloxone pretreatment in the rat model adjuvant-induced arthritis. Conclusions : Bee venom aqua-acupuncture has an analgesic effect on the rat model of adjuvant-induced of adjuvant-induced arthritis and has antinociception mediated by ${\alpha}_2$-adrenergic system.

To study the analgesic and effect and its mechanism of eletroacupunture(EA) on the chronic inflammatory pain 50 rats were induced with arthralgesia by injecting complete freund's adjuvant(CFA). Two weeks after the injection of CFA, EA stimulation(2Hz, 0.07mA, 0.3ms) was delivered to Jogsamni($ST_{36}$) for 20 minutes. Analgesic effect was evaluated by using the tail flick latency(TFL) and the analgesic mechanism was observed by applying TFL with the pretreatment with naloxone and yohimbine. The results were as follows ; 1. TFL level for the model of adjuvant-induced arthritis decreased as time went by and it induced the hyperalgesia. 2. EA stimulation delivered to Jogsamni($ST_{36}$) for 20 minutes in the rat model of adjuvant-induced arthritis brought analgesic effect and its effect had lasted for 40 minutes after the stimulation. 3. The analgesic effect of Jogsamni($ST_{36}$) EA in the rat model of adjuvant-induced arthritis was blocked by pretreatment with naloxone(2mg/kg,i.p). This result suggests that the EA effect on the chronic inflammatory pain can be related to the endogenous opioid mechanism. 4. The analgesic effect of Jogsamni($ST_{36}$) EA in the rat model of adjuvant-induced arthritis was blocked by pretreatment with naloxone(2mg/kg,i.p). This result suggests that the EA effect on the chronic inflammatory pain can be related to the ${\alpha}_2$-adrenergic mechanism.

Ohyaksungisan, combined preparation of crude drugs, has been used for hemiplegia, arthralgia and paralysis in traditional Korean medicine. The anti-inflammatory activity of the aqueous extract from Ohyaksungisan(OSSE) was investigated on acetic acid-induced edema and adjuvant arthritis in rats. Acute toxicity and analgesic action in mice were also examined. Its anti-inflammatory activity on 5% acetic acid-induced edema and adjuvant arthritis was observed with oral administration. The acute toxicity showed 10% mortality at 2400 mg/kg (p.o), but was not showed at 1200 mg/kg (i.p). OSSE was showed to have significant analgesic action (P<0.05) at 150 mg/kg and this action was strengthened at 300, 600 mg/kg. The anti-inflammatory effect was showed significant preventive effect on the hind paw edema from 90 min. and the adjuvant arthritis, when orally administered for 19 days. showed significant inhibitory effect on the hind paw edema from the 5th day.

Objectives : The purpose of this study is to investigate the effect of $Clematidis$ radix herbal-acupuncture solution, on collagen, adjuvant, lipopolysaccharide and phospholipase A2 induced rheumatoid arthritis in mice. Methods : Arthritis index was measured for mouse that was injected subcutaneously in solution mixed chicken type II collagen with Freund's complete adjuvant. We injected Freund's complete adjuvant into right posterior part of the sole of a ICR mouse foot, which was measured by plethysmometer. The solution mixed $CRHS$ with Tris-HCI, $CaCl_2$, substrate, enzyme was done a chemical action for thirty minutes, and then inhibitory activity of PLA2 enzyme was expressed with inhibition percentage by utilizing isolated arachidonic acid. COX-2 was induced by adding LPS to RAW 264.7 cell, and COX-2 activity was measured by western blot analysis and $PGE_2$ Biotrak kit. Results : $CRHS$ also inhibited Freund's complete adjuvant induced chronic rheumatoid arthritis in mice. $CRHS$ showed significant inhibition of type I and type II $PLA_2$ activities in a dose dependent manner. Furthermore, $PGE_2$ production was decreased with $CRHS$ and lipopolysaccharide-induced COX-2 protein expression was significantly inhibited by $CRHS$. Conclusions : These results suggest that $CRHS$ has an therapeutic effect on drug induced-rheumatoic arthritis by inhibiting $PLA_2$ and COX-2 activities.

Objectives : This study was conducted to determine whether or not Kangwhaldoche-tang(Qianghuodaozhi-tang) (KDT) aqueous extracts can protect articular cartilage losses on the Freund's complete adjuvant(FCA)-induced rat rheumatoid arthritis. Methods : 520, 260 or 130 mg/kg of KDT were orally administered once a day for 14 days from 14 days after FCA treatments, and 15 mg/kg of dexamethasone was intraperitoneally administered as reference drug in this experiment. Changes on the body weight, knee circumferences, gross arthritis score, inflammatory tissue prostaglandin(PG) $E_2$ levels were monitored with cartilage collagen components and glucosaminoglycans(GAGs) compositions - chondroitin sulphate, heparin sulphate and hyaluronic acid in the present study. Results : As results of FCA treatment, classic rheumatoid arthritis featuring dramatic decreases of the body weights, cartilage collagen and GAGs contents with increases of the knee circumferences, gross arthritis scores and inflammatory tissue $PGE_2$ levels, were demonstrated in the present study. However, these changes from FCA - induced rheumatoid arthritis were clearly inhibited by treatment of dexamethasone and all three different dosages of KDT. Although overall anti-inflammatory effects of KDT 520 mg/kg were lowered than those of dexamethasone 15 mg/kg treated rats, KDT 520 mg/kg showed more favorable preserve effects on the cartilage GAGs and KDT 260 mg/kg treated rats showed similar preserve effects as compared with dexamethasone 15 mg/kg in this experiment. Conclusions : The present results supported that over 75 mg/kg of KDT showed favorable anti-arthritic effects on the FCA-induced arthritis mediated by suppression of $PGE_2$, representative inflammatory mediator, and may help improve rheumatoid arthritis.
