Objectives : The objective of this study is to investigate Anti-nociceptive and anti-inflammatory effects of Clematidis Radix (CR) herbal-acupuncture on the test rats with induced acute pain. Methods : The effects of Clematidis Radix (CR)-distillates were investigated in three types of models with three different pain. Highly purified distillate of CR called CR herbal-acupuncture was injected to Zusanli ($ST_{36}$) acupoint. In the tail flick test, the CR herbal-acupuncture treatment did not show a significant effect of relieving acute pain. To investigate the anti-inflammatory effect of CR herbal-acupuncture, the second testing model'pain was induced by injecting formalin to its planter. For the last model, carrageenan was injected into tarsal joint. the medicinal effect of CR herbal-acupuncture was evaluated through the behavioral analyses such as licking time, weight distribution ratio and ankle circumference. Results : In the formalin test, the analgesic effect of CR herbal-acupuncture was more pronounced in the late phase (for 20 min after the early phase) than in the early phase (for the first 10 min post formalin injection). It was proven by weight distribution ratio testing and ankle edema testing that herbal-acupuncture of CR inhibited arthritis caused by the carrageenan. Conclusions : These results revealed that CR herbal-acupuncture was effective to alleviate the inflammatory pain and could be used as an analgesic treatment with an anti-inflammatory effect.

본 연구는 랫드의 우측 후지 발바닥에 Freund's complete adjuvant를 투여하여 관절염을 유발한 후에 N-methyl-2-pyrrolidone (NMP) 기제를 첨가한 경피용 ketoprofen 제제의 관절염 치료 효과를 확인하기 위해서 수행되었다. NMP를 함유한 ketoprofen 경피용 제제의 관절염 치료 효과를 알아보기 위해서 Sprague-Dawley 암칫 랫드를 대조군과 약물 투여군으로 분리하고, 약물 투여군은 ketoprofen 10mg/rat 투여군(K10군)과 NMP가 함유된 ketoprofen 10mg/rat 투여군(NK10군)으로 분류하였다. 실험적 관절염을 유발시킨 후 $^{99m}Tc-MDP$을 이용한 bone scan에서 골병변이 나타난 7일 후부터 14일 동안 약물을 매일 한번씩 랫드의 등에 극소 도포하여 다음과 같은 결론을 얻었다. NMP의 기제를 첨가한 ketoprofen 경피용 제제가 ketoprofen단독 경피용 제제 보다 후지 부종을 현저하게 감소시켰고 단순 방사선 사진과 scintigraphy에서 관절염에 의한 골 파괴를 효과적으로 억제하였다. 이상의 연구 결과를 기초로 하여 관절염 치료에 있어 NMP를 함유한 ketoprofen 경피용 제제가 ketoprofen단독 제제보다 효과가 있다는 결론을 얻을 수 있었다.

Purpose : This research was conducted to investigate the effect of sweet bee venom pharmacopuncture and low level laser acupuncture on paw edema, pain index, anti-inflammatory factor, AST, ALT and complete blood cell count of a rat model with Complete Freund's Adjuvant-induced arthritis. Methods : Five experimental groups were formed with each consisting of six rats: normal group, control group, sweet bee venom pharmacopuncture group, lower level laser acupuncture group, and sweet bee venom pharmacopuncture, lower level laser acupuncture group. The experimental model of arthritis was induced by two injections of Freund's adjuvant into the left knee joint of Sprague Dawley(SD) rats. The second injection of Freund's adjuvant was given ten days after the first one. Ten days later, sweet bee venom pharmacopuncture and low level laser acupuncture were administered separately or together by assigned groups at $GB_{34}$ and $GB_{39}$ of rats twice a week for a total of six times. Thereafter, edema rate, pain index, tumor necrosis factor-${\alpha}$, interleukin-6, aspartate aminortansferase, alanine aminotransferase and complete blood cell count were measured. Results : We noticed synergic effects of sweet bee venom pharmacopuncture and low level laser acupuncture according to the results of the paw edema and Von Frey pain index. The sweet bee venom pharmacopuncture(BVA) and sweet bee venom pharmacopuncture+ low level laser acupuncture(BVA+LLA) groups experienced a more significant effect when compared with the control group. Conclusions : These results suggest that Sweet Bee Venom Pharmacopuncture and low level laser acupuncture at GB34 and GB39 have a significant anti-inflammatory effect on Freund's adjuvant arthritis in rats.

Biflavonoid is one of unique classes of naturally-occurring bioflavonoids. Certain biflavonoids including amentoflavone were previously reported to have inhibitory effect on the group 11 phospholipase $A_2$ activity. Amentoflavone was also found to inhibit cyclooxygenase from guinea-pig epidermis without affecting lipoxygenase. In this study, anti-inflammatory and analgesic activities of amentoflavone were evaluated. When amentoflavone was administered intraperitoneally, it showed a potent anti-inflammatory activity as determined by amelioration of croton-oil induced mouse ear edema. It also showed a potent anti-inflammatory activity in the rat carrageenan paw edema model ($ED_{50}$=42 mg/kg) compared to the activity of prednisolone (35 mg/kg) and indomethacin (10 mg/kg). However, amentoflavone did not show a significant inhibitory activity against rat adjuvant-induced arthritis, a chronic inflammatory model. In addition, amentoflavone was found to possess a potent analgesic activity in the acetic acid writhing test ($ED_{50}$=9.6 mg/kg) compared to the activity of indomethacin (3.8 mg/kg). These results suggest that amentoflavone may be a potential lead for a new type of anti-inflammatory agents having dual inhibitory activity of group 11 phospholipase $A_2$ and cyclooxygenase.

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.

Inflammatory mediators has been recognized as an important role in the pathogenesis of rheumatoid arthritis (RA). IL-17 is increasingly recognized as an important regulator of immune and inflammatory responses, including induction of proinflammatory cytokines and osteoclastic bone resorption. Evidence of the expression and proinflammatory activity of IL-17 has been demonstrated in RA synovium and in animal models of RA. However, the signaling pathways that regulate IL-17 production remain unknown. In the present study, we investigated the role of the phosphatidylinositol 3 kinase (PI3K)-Akt pathway in the regulation of IL-17 production in RA. PBMC were separated from RA (n=24) patients, and stimulated with various agents (anti CD3, anti CD28, PHA, ConA, IL-15). IL-17 levels were determined by sandwich ELISA and RT-PCR. The production of IL-17 was significantly increased in cells treated with anti-CD3 antibody, PHA, IL-15 or MCP-1 (P<0.05). ConA also strongly induced IL-17 production (P<0.001), whereas TNF-alpha, IL-1beta, IL-18 or TGF-beta did not. IL-17 was detected in the PBMC of patients with osteoarthritis (OA) but their expression levels were much lower than those of RA PBMC. Anti-CD3 antibody activated the PI3K-Akt pathway and activation of the PI3K-Akt pathway resulted in a pronounced augmentation of nuclear factor kappaB ($NF-{\kappa}B$). IL-17 production by activated PBMC in RA is completely or partially blocked in the presence of $NF-{\kappa}B$ inhibitor PDTC and PI3K-Akt inhibitor, wortmannin and LY294002, respectively. Whereas the inhibition of AP-1 and extracellular signal-regulated kinase (ERK)1/2 did not affect IL-17 production. These results provide new insight into that PI3K/Akt and $NF-{\kappa}B$ dependent signal transduction pathway could be involved in the overproduction of key inflammatory cytokine, IL-17 in rheumatoid arthritis.

K/BxN serum can transfer arthritis to normal mice owing to the abundant autoantibodies it contains, which trigger innate inflammatory cascades in joints. Little is known about whether gut-residing microbes affect host susceptibility to autoantibody-mediated arthritis. To address this, we fed C57BL/6 mice with water containing a mixture of antibiotics (ampicillin, vancomycin, neomycin, and metronidazol) for 2 weeks and then injected them with K/BxN serum. Antibiotic treatment significantly reduced the amount of bacterial genomic DNA isolated from fecal samples, in particular a gene encoding 16S ribosomal RNA derived from segmented filamentous bacteria. Arthritic signs, as indicated by the arthritic index and ankle thickness, were significantly attenuated in antibiotic-treated mice compared with untreated controls. Peyer's patches and mesenteric lymph nodes from antibiotic-treated mice contained fewer IL-17-expressing cells than those from untreated mice. Antibiotic treatment reduced serum C3 deposition in vitro via the alternative complement pathway. IL-$17^{-/-}$ congenic C57BL/6 mice were less susceptible to K/BxN serum-transferred arthritis than their wild-type littermates, but were still responsive to treatment with antibiotics. These results suggest that gut-residing microbes, including segmented filamentous bacteria, induce IL-17 production in GALT and complement activation via the alternative complement pathway, which cause the host to be more susceptible to autoantibody-mediated arthritis.
