Objectives : To investigate the role of Meridian flow on acupuncture effect, we observed the therapeutic effects of electroacupuncture (EA) after Meridian blocking with pressure in arthritic rats. Methods : To make reliable and local monoarthritis, $40{\;}{\mu}l$ complete Freund's adjuvant was injected into the tibio-tarsal joint. EA was applied on acupoint GB30 while 5 Pascal pressure was added to the middle of the Gall bladder Meridian around GB31 between acupoint GB30 and arthritic foci (ipsilateral meridian blocking: IB) or opposite part of IB (contralateral part blocking: CB). To observe the change of arthritis, extension and flexion pain scores and circumferential differences were evaluated once a week. Results : EA stimulation without blocking reduced arthritic pain significantly. IB abolished the acupuncture effects and there was no statistical difference with the arthritic control group, whereas the CB group still showed the therapeutic effects of acupuncture. Conclusions : This finding strongly supports that the Meridian blocking with local pressure reduced the therapeutic effect of EA.

Among the arthritis symptoms, chronic pain is the most serious, and it can profoundly affect the quality of human life. Unfortunately, the mechanism of development in arthritis and arthritic pain has not yet been precisely elucidated. Accumulating evidence indicates that nitric oxide (NO) plays a pivotal role in nociceptive processing in the spinal cord. However, the modulation mechanism of NO in the peripheral site of arthritis and arthritic pain has not been clarified. Therefore, I determined in the present study which nitric oxide synthase (NOS) was involved in the induction of arthritis and arthritic pain. Monoarthritis was induced by intra-articular injection of carrageenan (2%, $50{\mu}l$) into rats, and resulted in the reduction of weight load on the injected leg, increase of knee joint diameter and inflammatory response. Pre-treatment of rats with L-N6-(1-iminoethyl)-lysine (L-NIL, $500{\mu}g$, in $50{\mu}l$), an inhibitor of inducible NOS (iNOS), partially prevented the induction of pain-related behavior and partially reduced inflammatory response in the synovial membrane in the knee joint. These results suggest that iNOS in the knee joint may play an important role in the induction of pain-related behavior and inflammation, and that NO produced by iNOS may be associated with nociceptive signaling in the peripheral site.

Gout occurs mainly in monoarthritis and is found in more than 50% of cases in hallux of the foot. In addition, symptoms sometimes begin in the hand, wrist, and elbow, but they are rarely observed in the spine. The patient was referred for tuberculous polyarthritis due to antituberculosis drug failure. Inflammatory findings were observed in the lumbar, elbow, wrist, hand and foot areas. Surgery was performed on the foot area and a pathology diagnosis revealed gouty arthritis. We report this case with a review of the relevant literature.

Radix Paeoniae rubra (PR) has been widely used for recovering acute inflammation with swelling and pain in Far East Asian countries. In order to investigate the anti-arthritic effect of PR herbacupuncture, several behavioral parameters such as body weight, knee circumference, squeaking threshold, and weight distribution ratio were investigated in an adjuvant-induced mono-arthritis rat model. We performed PR herb-acupuncture on Zusanli (ST36) of the right hind-leg once every second day for a total of 6 times from the second day of initiating arthritis with adjuvant injection, while the control group was treated with saline in the same way. In the experimental group, body weight significantly increased, knee circumference and squeaking threshold significantly decreased indicating the reduction of edema, and both the pain and inflammatory swelling of the hind paws measured by incapacitance meter decreased. Conclusively, PR herb-acupuncture has more promising effect in alleviating arthritic pain and inflammation than saline-acupuncture in rat model, hence further clinical study is required.

Anti-nociceptive and anti-inflammatory effects of Clematidis Radix (CR)-distillates were investigated in three different pain animal models. Highly purified distillate of CR was injected to Zusanli (ST36) acupoint, called CR herb-acupuncture in the Korean traditional medicine. In tail flick latency test, the CR herb-acupuncture treatment did not show a significant effect of relieving acute phasic pain. To investigate the anti-inflammatory effect of CR herb-acupuncture, inflammatory pain was induced by subcutaneous injection of formalin to the plantar tissue or intra-articular injection of carrageenan to the tibio-tarsal joint in the rats. And the medicinal effect of CR herb-acupuncture was evaluated by analyzing pain behavior such as licking or biting behavior, or by measuring weight distribution ratio between two foot and ankle circumference. In the rat formalin test, the analgesic effect of CR herb-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 also significantly alleviated the carrageenan-induced monoarthritis, in terms of weight distribution ratio and ankle edema. These results revealed that CR herb-acupuncture was effective to treat the inflammatory pain and could be used as an analgesic treatment with an antiinflammatory effect.

In order to examine the anti-arthritic properties of ShinEumHur(SEH)-herbal acupuncture, an adjuvant-induced arthritic rat was generated by the intra-articular injection of dried cells of Mycobacterium tuberculosis emulsified in squalene into the right knee joint. Fifty microliter of SEH extract was injected into Zusanli(ST36) acupoint on the ipsilateral hind paw every other day for 2 weeks. The body weight, knee circumference, squeak threshold, and weight distribution ratio were analyzed as the assessment methods addressing arthritic symptoms such as arthritic pain, edema, and tenderness. The weight distribution ratio was measured by a digital-type analgesia instrument using the dual channel scale that separately measures the weight the arthritic rat distributes to each hind paw, and thus quantifies both of swelling and pain severities at once. The therapeutic effects of SEH-herbal acupuncture, assessed by squeaking threshold and weight distribution ratio, were observed on 8th day after the arthritis induction as compared to saline group and control group. On 10th day, SEH-herbal acupuncture therapy significantly started to alleviate the growing pattern of knee circumference of an arthritic rat in the range of 0.2㎝. However, the loss of body weight was not significantly recovered. Taken together, the SEH-herbal acupuncture exhibited the significant therapeutic efficiency to treat adjuvant-induced monoarthritis in rat.

목적 : 본 연구는 (a) 저빈도 전침의 만성 단발성 관절염에 대한 치료 효과와 (b) 척수에서 동통과 관련되는 지표인 P 물질과 trk A mRNA의 발현조절에 미치는 영향을 연구하기 위해 실행되었다. 방법 : Complete Freund's adjuvant를 실험동물의 우측 경족근관절에 주입하여 관절염을 유발시키고 9주 동안 관찰하였다. 만성 관절염의 최적의 치료조건을 찾기 위하여 각각 세 종류의 경혈(환도, 용천, 족삼리)과 전침자극강도(0.5, 1, 2 mA)를 사용하여, 행동학적 지표로서 동통을 측정하였다. 측정 결과 가장 큰 효과를 나타낸 군을 선택하여 RT-PCR 방법을 사용하여 P 물질 및 trk A mRNA의 변화를 척수 후각과 후근신경절에서 측정하였다. 결과 : 관절의 굴신을 통한 통증 검사와 족과관절 둘레 길이 측정을 통하여 관찰한 결과 원위부에 위치한 환도에 저강도의 자극을 시행한 경우(환도, 0.5 mA)가 가장 우수한 치료 효과를 나타내었다. RT-PCR을 시행한 결과, 환측 후근신경절의 P물질이 관절염 유발 대조군의 경우 정상군에 비해 증가하였고 환도-0.5mA 군에서 다시 감소하는 것을 관찰하였으며, trk A는 관절염 유발군의 경우 척수 후각에서 양측성 증가를 나타내었고 이는 전침치료에 의해 다시 감소되는 것을 관찰하였다. 결론 : 환도 0.5mA의 저빈도 전침은 관절염을 효과적으로 감소시킬 뿐 아니라 관절염으로 증가된 후근신경절의 P 물질과 척수후각의 trk A mRNA 발현을 효과적으로 감소시켰으며, 이는 원위취혈로 선혈된 환도혈의 만성관절염에 대한 치료효과를 분명히 보여준다고 할 수 있다.
