Objective : To investigate effects of herbal preparations formulated(Gihyeolgwanjeolbang-A, CWS-A) on complete Freund's adjuvant (CFA)-induced arthritis in rats. Method : Arthritis was induced by injecting CFA subcutaneously into the left knee joint and paw, and the herbal preparations formulated(CWS-A I, 82.3 mg/kg ; CWS-A II, 164.6 mg/kg) was administered orally (i.g.) for 10 consecutive days beginning on day 10 after the injection. External shape, paw edema, inflammatory cytokines tumor necrosis factor alpha (TNF-alpha) and interleukin-1 beta (IL-1beta), and histological observation were assessed. Result : In swelling of the paw, CWS-A I and CWS-A II group in 15 days and 20 days were significantly reduced compared to controls. In serum ALT, CWS-A I and CWS-A II group were significantly reduced compared to controls. In TNF-${\alpha}$, CWS-A I and CWS-A II group were a tendency reduced compared to controls. In HGB, HCT, MCHC of erythrocytes, CWS-A II group was increased compared to controls. In histological observations, CWS-A II group was observed synoviocytes more than control group and was observed proteoglycans in the deep layers. Conclusion : The data suggest that CWS-A significant anti-arthritic effects that may be mediated by suppressing inflammatory parameters.

Objectives : The aim of this study is to evaluate the analgesic effect of electroacupuncture on Jogsamni (ST36) in the collagen-induced arthritis rats and investigate the role played by opioid receptor subtypes $({\mu},\;{\delta},\;{\kappa})$ in the antinociceptive effect of electroacupuncture (EA) In the thermal hyper algesia test. Methods : Immunization of male Sprague-Dawley rats with bovine type H collagen emulsified in incomplete Freund's adjuvant, followed by booster injection 2 weeks later induced collagen-induced arthritis (CIA). The thermal hyperalgesia was evaluated weekly with tail flick latency (TFL). In the fourth week after first immunization, EA stimulation (2 Hz, 0.07 mA, 0.3 ms) was delivered into Jogsamni (5736) for 20 minutes. Analgesic effect was evaluated by using the tail flick latency (TFL) after intraperitoneal injection of normal saline, naloxone, naltrindole and nor-binaltorphimine respectively to CIA rats. Results : The results were as follows; 1. The TFL were gradually decreased in CIA as time elapsed after e immunization of arthrogenic collagen and the maximum value was reached between the third to fifth week. 2. EA stimulation on 5736 inhibited chronic inflammatory pain induced by CIA. 3. The analgesic effect of EA was inhibited by pretreatment of ${\mu}-receptor$ antagonist (naloxone),${\delta}-receptor$ antagonist (naltrindole) and ${\kappa}-receptor$ antagonist (nor-binaltorphimine) respectively. Conclusion : Electroacupuncture has an analgesic effect on the CIA rat and has an antinociception mediated by 8, 5, H receptors.

Introduction: Guillain-Barre syndrome(GBS) is defined as a recognizable clinical entity that is characterized by rapidly evolving symmetric limb weakness, a loss of tendon reflexes, absent or mild sensory signs, and variable autonomic dysfunctions. Recently there is an opinion that Acute Inflammatory Demyelinating Polyradiculoneuropathy'(AIDP) is more effective than 'GBS' for the symptoms. These symptoms are applicable to rheumatic arthritis(痺), flaccid paralysis of limb(?) caused by wind, cold and dampness(風, 寒, 濕) from an oriental medical view point. On this, we reported one case that diagnosed as 'complex of rheumatic arthritis(痺) and flaccid paralysis of limb(?)' at our oriental medical hospital. Result: we considered these symptoms as 'complex of rheumatic arthritis(痺), flaccid paralysis of limb(?)'. In accordance with the result, we treated the patient with Chung-Sang Tong-Jung On-Ha(淸上通中溫下). We concluded that external factors such as wind, cold and dampness(風, 寒, 濕) and internal factors like vital energy's disharmony(生氣不調和) affected the patient.

Objectives : To evaluate the analgesic effect of electroacupuncture on Choksamni (ST36) in the collagen-induced arthritis rats and investigate the role played by serotonergic receptor subtypes $(5-HT_{1A},\;5-HT_{1B},\;5-HT_4)$ in the antinociceptive effect of electroacupuncture in the thermal hyperalgesia test. Methods : Immunization of male Sprague-Dawley rats with bovine type II collagen emulsified in incomplete Freund's adjuvant, followed by booster injection 14 days later induced collagen-induced arthritis (CIA). The thermal hyperalgesia was evaluated weekly with tail flick latency (TFL). In the fourth week after first immunization. EA stimulation (2Hz, 0.07mA, 0.3ms) was delivered into Choksamni for 20 minutes. We measured the analgesic effect of EA with TFL afer intraperitoneal injection of normal saline, WAYl00635, SB216641 and GR125487. Results : TFLs were gradually decreased in CIA as time elapsed after the immunization of arthrogenic collagen and the maximum value was reached from third to fifth week. EA stimulation on ST36 inhibited chronic inflammatory pain induced by CIA. The analgesic effect of EA was inhibited by pretreatment of $5-HT_{1A}$. antagonist (WAYl00635), $5-HT_{1B}$ antagonist (SB216641) and $5-HT_4$ antagonist (GR125487). Conclusion : Electroacupuncture has the analgesic effect on chronic inflammatory pain and its mechanism was mediated by $5-HT_{1A}$, $5-HT_{1B}$ and $5-HT_4$.

To gain insight on the role of pro-inflammatory cytokines in the pathogenesis and treatment of rheumatoid arthritis (RA), the phorbol 12-myristate 13-acetate (PMA)-induced IL-6 gene expression and the effect of caffeic acid phenethyl ester (CAPE) on the PMA-induced IL-6 gene expression were investigated in human fibroblast-like synoviocytes (FLSs). Synovial tissue samples were obtained from rheumatoid arthritis patients, and FLSs were isolated. The cells were stimulated with PMA (100 nM) for 6 hrs to induce IL-6 gene. The cells were pretreated with CAPE (20, 50, $100{\mu}M$) prior to PMA treatment. PMA increased IL-6 RNA expression, binding activities of transcription factors ($NF-{\kappa}B$, AP-1) to IL-6 promoter, and IL-6 promoter activity. However, CAPE inhibited PMA-induced IL-6 mRNA expression in dose-dependent manner, and also inhibited the increased binding activities of transcription factors to IL-6 promoter and IL-6 promoter activity. These results suggest that CAPE might regulate PKC-mediated IL-6 expression and inflammatory reactions in RA.

This study was carried out to know the immunity responses of the Spatholubus suberectus Dunn(hereinafter referred to STSD) to the synovial cells isolated from patients with rheumatoid arthritis. Various experiments were performed in vitro to analyse the immunity effects of STSD. Gene expression and production of pro-inflammatory cytokines such as IL-1β, IL-6, TNF-α, iNOS and COX-2 were determined by RT-PCR and ELISA kit. And also the binding activity of NF-kB and AP-1 were measured by Electromobility shift assay (EMSA) and the production of ROS was measured by flow cytometry. The results were obtained as follows 1. The gene expression and production of pro-inflammatory cytokines IL-1β, IL-6, TNF-α were reduced significantly. 2. The gene expression of iNOS and COX-2 were reduced. 3. The binding activity of NF-kB and AP-1 were inhibited. 4. The production of ROS in human synovial cells was reduced significantly. Comparison of the results for this study showed that STSD had immunomodulatory effects of suppressing or enhancing. So we expect that STSD should be used as a effective drugs for not only rheumatoid arthritis but also another auto-immune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

Purpose: The aim of the present study was to examine the effects of a 4-week aromatherapy on pain and inflammation in patients suffering from rheumatoid arthritis. Methods: A quasi-experimental study using a nonequivalent control group, pretest-posttest non-synchronized design was used. To analyze the data, descriptive statistics, Chi-square test, independent samples t-test, and Fisher's exact test were used. Results: After a 4-week aromatherapy, tender joint count (M=5.67 to 4.17), swollen joint count (M=4.13 to 2.54), and patient's assessment of pain (M=43.33 to 31.08) decreased significantly for the aromatherapy participants compared to the control group. But there was no significant difference between the groups in erythrocyte sedimentation rate. Conclusion: These findings suggest that aromatherapy could decrease joint pain, tenderness, and swelling in patients with rheumatoid arthritis, but some modifications in aromatherapy intervention and research method will be required to examine the effects of aromatherapy on inflammatory level in this population.

Purpose: To describe the recent clinical results and complications of total elbow arthroplasty based on the literature review. Materials and Methods: The indications of total elbow arthroplasty include rheumatoid or inflammatory arthritis, posttraumatic arthritis, anklylosed elbow, tumor resection which cannot recover elbow function by other reconstructive procedures, and comminuted distal humerus fracture in elderly patients. Complications are aspetic loosening, infection, prosthesis fracture, periprosthetic fracture, ulnar neuropathy, ectopic ossification, triceps insufficiency, dislocation, and bushing wear. Results and Conclusion: Mean 10 year survival rate following total elbow arthroplasty has been reported 85% on the basis of revision. The prognosis in patients with an inflammatory arthritis is reported to be best, and loosening rate in patients with a posttraumatic arthritis tends to be high. Complication rate is known to be higher than that of other joint arthroplasty. In particular, deep infection occurs in 3~5% of the patients. Total elbow arthroplasty provide satisfactory results when it is performed properly in selected patients who have an elbow joint with irreversible dysfunction and low level activities.

Rheumatoid arthritis is a chronic inflammatory disease that leads to bone and cartilage erosion. The inhibition of osteoblast differentiation by the inflammatory factor TNF-${\alpha}$ is critical for the pathogenesis of rheumatoid arthritis. To modulate TNF-${\alpha}$ mediated inhibition of osteoblast differentiation is required to improve therapeutic efficacy of rheumatoid arthritis. Here, we explored the potential role of rocaglamide-A, a component of Aglaia plant, in osteoblast differentiation. Rocaglamide-A prevented TNF-${\alpha}$ mediated inhibition of osteoblast differentiation, and promoted osteoblast differentiation directly, in both C2C12 and primary mesenchymal stromal cells. Mechanistically, Rocaglamide-A inhibited the phosphorylation of NF-${\kappa}B$ component p65 protein and the accumulation of p65 in nucleus, which resulted in the diminished NF-${\kappa}B$ responsible transcriptional activity. Oppositely, overexpression of p65 reversed rocaglamide-A's protective effects on osteoblast differentiation. Collectively, rocaglamide-A protected and stimulated osteoblast differentiation via blocking NF-${\kappa}B$ pathway. It suggests that rocaglamide-A may be a good candidate to develop as therapeutic drug for rheumatoid arthritis associated bone loss diseases.

Knee osteoarthritis is a common, but difficult problem to manage in primary care. Intra-articular hyaluronic acid injection has recently been frequently used for treating knee osteoarthritis. The adverse local reactions, except septic arthritis, following intra-articular hyaluronic acid injections are generally transient and not severe. Pseudoseptic arthritis is an extreme form of inflammatory arthritis that is not due to bacterial infection and it is important to distinguish this from true septic arthritis. In this article, we report 2 cases of acute pseudoseptic local reactions after intra-articular hyaluronic acid injections in patients with knee osteoarthritis.
