Objectives: The study was designed to evaluate anti-arthritic activity of Ajmodadi Churna (AC) and its effect on Complete freund's adjuvant (CFA)-induced arthritis in Wistar rats. Methods: Arthritis was induced by injecting 0.2 mL CFA into sub plantar surface of left hind paw. Test sample AC-1 and AC-2, 200 and 400 mg/kg, respectively was given to the animals for 21 consecutive days. The increase in swelling was observed after induction of arthritis. The paw edema was measured on 0, 3, 7, 14 and 21 day using Vernier caliper after the induction of arthritis. The collected blood samples further used for the estimation of red blood cells (RBC), white blood cells (WBC), erythrocytes sedimentation rate (ESR), and hemoglobin (Hb), using hematology analyzer. Serum concentration of IL-6 and TNF-α were also measured using rat ELISA kits. Results: Results showed that a significant reduction in paw edema was observed in AC-2 treated rats. The paw edema was restored on day 21 was 4.48 mm for AC-2, which is near to the control group. The arthritis score in treated rats was found to be considerably lower than in the control group i.e. 0.83 for AC-2 and 1.50 for AC-1. A decrease in levels of RBC and hemoglobin were observed in arthritic rats. Inflammation was significantly reduced and serum levels of IL-6 and TNF-α were lowered after treatment with the test drug. Conclusion: It can be concluded from the study that AC possess significant anti-arthritic activity. Furthermore, this condition was linked to a reduction in abnormal humoral immune responses.

Objectives The object of this study was to observe the favorable anti-arthritic effects of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) on Freund's complete adjuvant (FCA)-induced arthritic Wistar rats. Methods Rheumatoid arthritis was induced by intradermal injection of FCA, and 300, 150 or 750 mg/kg of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 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. All rats were sacrificed at 14 days after continuous oral treatment of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) or intraperitoneal administration of dexamethasone, and 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 compositions - chondroitin sulphate, heparan sulphate and hyaluronic acid in the present study. Results As results of FCA treatment, classic rheumatoid arthritis featuring dramatical decreases on the body weights, cartilage collagen contents and bone glucosaminoglycans-chondroitin sulphate, heparan sulphate and hyaluronic acid contents, with increases on the knee circumferences, gross arthritis scores and inflammatory tissue $PGE_2$ levels. However, these changes from FCA-induced rheumatoid arthritis were clearly reduced by treatment of dexamethasone and both two different dosages of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 and 150 mg/kg in the present study. Although FCA-induced arthritis were more favorably inhibited by treatment of dexamethasone 15 mg/kg as compared with Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg, marked decreases of body weights were detected in dexamethasone 15 mg/kg treated rats, and Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg showed similar preserve effects on the cartilage glucosaminoglycan compositions in this study. Conclusions The results obtained in this study suggest that over 300 and 150 mg/kg of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) showed favorable anti-arthritic effects on the FCA-induced arthritis mediated by suppression of $PGE_2$, a inflammatory mediator. However, detail mechanism studies should be conduced in future with the screening of the biological active compounds in this herb. Although overall anti-inflammatory effects Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg were lowered than those of dexamethasone 15 mg/kg treated rats, Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg treated rats showed similar preserve effects on the cartilage glucosaminoglycan compositions in this experiment.

Objectives : The object of this study was to observe the favorable anti arthritic effects of Euiiin-tang($y{\grave{i}}y{\breve{i}}r{\acute{e}}n-t{\bar{a}}ng$) aqueous extract(EIITe), has been traditionally used in Korean medicine for treating rheumatoid arthritis on collagen induced arthritic(CIA) DBA/1 mice. Methods : In the present study, effects of EIITe on the releases of human tumor necrosis factor(TNF)-${\alpha}$, interleukin(IL)-$1{\beta}$, matrix metalloproteinase(MMP)-13 and production of Nitric oxide(NO) were observed by in vitro. In addition, to observe the effects on the CIA mice, three different dosages of EIITe, 300, 150 and 150 mg/kg were orally administered once a day for 18 days from 24hrs after antigen challenges(type II collagen) on 21 days after immunization using Type II collagen Freund's complete adjuvant. Six groups, each of 8 DBA/1 mice per group were used in the present study as follows. Changes on the body weights, macroscopic arthritis scores, splenic weights, splenic TNF-${\alpha}$ and IL-6 contents, articular cartilage(femur and tibia) collagen and glycosaminoglycans-chondroitin sulphate, sulphate and hyaluronic acid contents, histopathological observations(microscopic arthritis scores, thicknesses of femur and tibia cartilage thicknesses were monitored, compared to that of dexamethasone, a potent anti inflammatory agents, 1 mg/kg treated mice. Results : As results of collagen challenges, marked decreases of body weights and gains, articular cartilage collagen and glycosaminoglycan - chondroitin sulphate, sulphate and hyaluronic acid contents were observed with increases of macroscopic arthritis scores, splenic weights, splenic TNF-${\alpha}$ and IL-6 contents, articular cartilage(in the both femur and tibia) loss and damages. However, these CIA signs were significantly and dosages dependently inhibited by treatment of EIITe 300 and 150 mg/kg as compared with CIA control, respectively. In addition, the releases of TNF-${\alpha}$, IL-$1{\beta}$, NO and MMP-13 were markedly and dose dependently inhibited by treatment of EIITe, invitro. Although CIA were more favorably inhibited by treatment of dexamethasone 1 mg/kg as compared with EIITe 300 mg/kg, marked decreases of body weights were detected in dexamethasone 1 mg/kg treated mice. Conclusions : The results obtained in this study suggest that over 150 mg/kg of EIITe showed favorable anti arthritic effects on the CIA mediated by immunomodulatory and/or anti oxidative effects. However, detail mechanism studies should be conduced in future with the screening of the biological active compounds in this herb. lthough CIA were more favorably inhibited by treatment of dexamethasone 1 mg/kg as compared with EIITe 300 mg/kg, marked decreases of body weights were detected in dexamethasone 1 mg/kg treated mice, in the present study.

Objectives : The present study was undertaken to determine whether an ethanol extract of Citri Pericarpium (CP-E), which is the pericarp of Citrus unshiu Markovich is efficacious against collagen-induced arthritis (CIA) in mice. Methods : CIA was induced in male DBA/1J mice by intradermal injection of bovine collagen-II in Freund's incomplete adjuvant (IFA). The mice in the onset of arthritis were treated daily with oral administration of CP-E ethanol extract at different doses (50 and 100 mg/kg/bw) for 28 days. Arthritis index, histopathologic changes and the levels of TNF-${\alpha}$ as well as anti-CII IgG in blood were evaluated to confirm the anti-arthritic effect of CP-E on CIA in rats. Results : The results showed that comparing with untreated CIA mice, treated with CP-E extract significantly decreased the arthritic scores and the pathological changes of knee joint tissues, and also reduced the serum levels of TNF-${\alpha}$ and anti-CII IgG in CIA-mice. These results indicate that CP-E extract may effectively alleviate inflammatory response on CIA, and its anti-inflammation can be attributed, at least partially, to the inhibition of proinflamamtory cytokine, TNF-${\alpha}$ in CIA. Conclusions : This study suggest that CP-E has a therapeutic potential in inflammatory joint diseases such as rheumatoid arthritis.

Candida albicans, a polymorphic fungus, causes systemic and local infections. Recent reports show that the fungus is a main etiological agent for the arthritis. For trea tment, antifungal drugs and/or rheumatoid drugs are used, but resistance and side effects limit application of the drugs. In search of new sources for treatment of the fungal arthritis, we choose Egb 761 (extract of Ginkgo leaves 761), one of the most popular over-the-counter herbal medicines. The Egb 761 contains two major ingredients such as terpene and flavonoid. In the present study, we examined if the terpene portion of Egb 761 had anti-inflammatory activity against C.albicans-caused arthritis. The terpene was extracted with combination of methanol and water from the Egb 761, followed by gel-permeation chromatography. Presence of terpene was determined by the Salkowski colorimetric method and HPLC analysis. For an animal model of inflammation induction, mice were given an emulsion form of C.albicans cell wall mixed with Complete Freund's Adjuvant (CFA) by footpad-injection. Results showed that intraperitoneal administration of the water-soluble portion that contained terpene and flavonoid reduced the inflammation. Whereas the terpene had anti-inflammatory activity, flavonoid portion had no such activity, For determination of possible mechanism of the activity, the terpene seemed to be suppression of nitric oxide (NO) production from LPS-treated macrophages. Taken together the Ginkgo terpene may have anti-inflammatory effect against C.albicans-caused arthritis, possibly by blocking NO production.

Objectives : This study was to investigate the effect of high frequency electroacupuncture at $ST_{36}$ acupuncture point on the Complete Freund's Adjuvant (CFA) induced rat arthritis pain model. Methods : Arthritis was induced by intradermal injection of CFA into base of tail. Experimental groups were divided into 4 groups; Normal, Control and Jok-Samri ($ST_{36}$) and Non-Acupuncture point (NA). Normal group, non-arthritic group, was injected with normal saline，and the others groups were injected CFA. $ST_{36}$ group was treated by 120 Hz electroacupuncture at $ST_{36}$ acupuncture point, and NA group was treated by 120 Hz electroacupuncture at non-acupuncture point. Each groups were evaluated by the change of c-fos positive neurons in periaqueductal gray (PAG) and hippocampus by using an image analyzer and a microscope. Results: - In the PAG region, the number of fos-positive cells in the $ST_{36}$ group ($42.37{\pm}5.08$) were significantly (p<0.05) decreased compared with the control group ($64.56{\pm}6.35$). - In the PAG region, the number of fos-positive cells in the NA group were meaninglessly decreased compared with the control group - In the Cornu Ammonis(CA)l region of hippocampus, the number of fos-positive cells in the $ST_{36}$ group ($7.00{\pm}1.08$) and NA group ($5.56{\pm}2.01$) were significantly (p<0.05) decreased compared with the control group ($13.81{\pm}1.24$). - In the dentate gyrus region of hippocampus, the number of fos- positive cells in the $ST_{36}$ group ($10.75{\pm}0.98$) and NA group ($6.56{\pm}0.78$) were significantly (p$26.45{\pm}1.82$). Conclusions : It is expected that high frequency electroacupuncture can be used a treatment of arthritic pain.

Objectives : This study was to investigate the effect of low frequency electroacupuncture according to acupoints combination on NOS positive neurons in the PAG and Hippocampus of Rat with adjuvant induced Rheumatoid arthritis. Methods : Arthritis was induced by intradermal injection of FCA into base of tail. Experimental group were divided into 6 group ; Normal, Control, $ST_{36}$, $SP_9$, $ST_{36}+SP_9$, and NA. Normal group was injected with normal saline and not treated electroacupuncture. Control group was injected with FCA and not treated electroacupuncture. ST36 group was injected with FCA and treated by 2 Hz electroacupuncture at $ST_{36}$. $SP_9$ group was injected with FCA and treated by 2 Hz electroacupuncture at $SP_9$. $ST_{36}+SP_9$ group was injected with FCA and treated by 2 Hz electroacupuncture at $ST_{36}+SP_9$. NA group was injected with FCA and treated by 2 Hz electroacupuncture at non acupoint. Each groups were evaluated by the number of NOS-positive neurons in PAG and hippocampus by using an image analyzer and a microscope. Results : 1. The number of NOS-positive neurons of the NA group were significantly decreased in the CA2-3. 2. The number of NOS-positive neurons of the ST36 group were significantly decreased in the PAG and CA2-3. 3. The number of NOS-positive neurons of the SP9 group were significantly decreased in the PAG and DG 4. The number of NOS-positive neurons of the ST36+SP9 group were significantly decreased in the PAG, CA1 and DG. Conclusions : It is expected that low frequency electroacupuncture can be used a treatment of rheumatoid arthritic pain and that treatment of electroacupuncture at combined acupoints is more efficient than treatment of low frequency electroacupuncture at one acupoint.

Objectives This study was designed to evaluate the healing effect of Cordyceps Militaris (CM) on collagen II-induced arthritis rats. Methods Sprague-Dawley rats were randomly divided into 6 groups (normal, control, positive control, CM with low/medium/high dosage each). Type II collagen mixed with complete Freund's adjuvant (with 1:1 v/v) was injected subcutaneously, and the mixture was injected in a same manner one week after the first injection to boost arthritis. Arthritis index, paw thickness and von Frey test were conducted to observe physical changes. hematoxylin and eosin (H&E) staining was performed to observe knee cartilage. The levels of messenger RNA (mRNA) expressions of interleukin (IL)-1𝛽, IL-6, tumor necrosis factor-alpha (TNF-𝛼) in spleen were assessed by real-time polymerase chain reaction. Results Rheumatoid arthritis is an autoimmune disease that occurs on multiple joints and can lead to temporary shape change of bones or organ failure in severe cases. Here, we aimed to determine the effect of CM extract on rheumatoid arthritis by measuring paw thickness, arthritis index, conducting von Frey test and H&E staining, and evaluating the level of IL-1𝛽, IL-6, TNF-𝛼. As a result, paw thickness, arthritis index significantly decreased in low concentration group, hind leg became less sensitive in all expermental groups. Also, histological analysis showed that the damage of knee cartilage was prevented in all experimental groups. The level of mRNA of IL-1𝛽, IL-6, and TNF-𝛼 in spleen was analyzed to decide the effectiveness of CM extract. IL-1𝛽 did not show significant change, but IL-6 and TNF-𝛼 showed significant decrease in at least one of the experimental groups. Conclusions CM showed protective effect on knee tissue destruction and improved the physical conditions of the leg involving arthritis. Also, it showed that CM has anti-inflammatory effect on specific cytokines inducing rheumatoid arthritis. In conclusion, this study demonstrated that the therapeutic potential of CM for the treatment rheumatoid arthritis, and set the foundation for the further studies.
