Objectives : The effects of water extract of deer antler herbal-acupunture solution(DHS), prepared from the pilose antler of Cervus korea TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immunosuppressive and immune-activating Korean herbal- acupuncture, on collagen-induced arthritis(CIA:RA model) in mice was studied. Destruction of cartilage and bone are hallmarks of human rheumatoid arthritis, and controlling these erosive processes is the most challenging objective in the treatment of RA. Methods : We investigated the tissue protective effects of deer antler treatment using established murine collagen-induced arthritis(CIA) as a model. Potential synergy of low dosages of anti-inflammatory glucocorticosteroids and deer antler was also evaluated. Results : Treatment of established murine CIA with deer antler herbal-acupunture solution(DHS) $(10-50{\mu}g/day)$ suppressed disease activity and protected against cartilage and bone destruction. Although $10-50{\mu}g/day$ DHS had only a moderate effect on the inflammatory component of the disease activity, it strongly reduced cartilage pathology, as determined by histological examination. Serum cartilage oligomeric matrix protein(COMP) levels were significantly reduced, confirming decreased cartilage involvement. Histological analysis showed that bone destruction was prevented. DHS administration increased serum IL-1Ra levels and reduced anticollagen type II antibody levels. Treatment with low-dose $DHS(1{\mu}g/day)$ was ineffective in suppressing disease score, serum COMP or joint destruction. Synergistic suppression of both arthritis oseverity and COMP levels was noted when low-dose DHS was combined with prednisolone(0.05mg/kg/day), however, which in itself was not effective. Conclusion : DHS was shown to have the inhibiting effects against $IL-1{\alpha}-$ and $IL-1{\beta}-stimulated$ bone resorption. These results indicated that the DAS is not only highly stable and applicable to clinical uses in bone resorption, but also it will be served as a potent anti-inflammatory and anti-arthritic agents for treatment of human RA.

본 연구에서는 오디추출복합물(mulberry extract complex, MEC)의 퇴행성관절염 증상 완화 및 개선 효과 가능성을 탐색하기 위하여 monosodium iodoacetate(MIA)로 유도한 퇴행성관절염 in vivo 실험모델을 이용하였다. 연골의 주요 구성성분인 glycosaminoglycan(GAG) 및 collagen의 농도를 실험동물의 연골에서 측정한 결과 MIA로 인해 감소하였던 GAG 및 collagen의 농도가 MEC를 경구 투여한 실험군에서 농도 의존적으로 증가하였다. 또한 교원질 합성을 억제하고 분해를 촉진하는 matrix metalloproteinase-2, 9, 13의 농도를 측정한 결과는 MEC의 농도에 따라 감소하는 결과를 보여주었다. 연골 손상 지표인 cartilage oligomeric matrix protein과 C-terminal telopeptide 2의 측정결과에서는 대조군보다 유의성 있는 감소를 나타내어 MEC가 퇴행성관절염의 진행 억제에 도움을 줄 수 있을 것으로 생각된다. 관절염 지수 평가에서도 MEC는 모든 농도에서 대조군보다 유의성 있게 개선되는 결과를 나타내었다. 이상의 실험 결과를 통하여 MEC가 퇴행성관절염에서 나타나는 연골 구성성분의 분해를 억제하고, 여러 중요한 퇴행성관절염 진행 인자를 효과적으로 억제하여 결국 연골파괴 감소와 더불어 통증을 줄여줌으로써 퇴행성관절염에 대한 증상 완화 및 개선 효과가 있을 수 있는 건강기능식품의 원료로 활용될 수 있을 것으로 생각된다.

Objectives : 3-Acetyl-11-keto-𝛽-boswellic acid (AKBA) is a major active compound in Boswellia serrata. We investigated the arthritic changes following AKBA administration in monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods : All rats were randomly divided into five groups: Normal, Control, INDO (indomethacin 2 mg/kg treated), AKBA30 (AKBA 30 mg/kg treated), and AKBA60 (AKBA 60 mg/kg treated); drugs were given 2 weeks before MIA injection. For all groups except the normal group, 50 µL of sterile saline with MIA (80 mg/mL) was injected into the right knee joint 2 weeks after drug administration. The drug administration was continued for 4 weeks from 1 week after osteoarthritis induction. The histomorphological changes of knee joint cartilage were observed by H&E staining. Also, the levels of glycosaminoglycan (GAG), cartilage oligomeric matrix protein (COMP), 5-lipoxygenase (5-LOX), 5-LOX-activating protein (FLAP), and leukotriene B₄ (LTB₄) in the knee joint were determined by the ELISA kits. The expressions of mitogen-activated protein kinases (MAPKs), inflammatory cytokines, and matrix metalloproteinases (MMPs) in knee joint were detected by Western blot. Results : Data show that levels of 5-LOX, FLAP, LTB4, and COMP were downregulated significantly in the AKBA treated groups when compared to those in the Control group. On the other hand, GAG levels were significantly elevated. As a result of Western blot, the AKBA-treated groups significantly inhibited phosphorylation of MAPKs. In addition, significant downregulation of the expression of inflammatory cytokines and MMPs was found in the AKBA-treated groups. Conclusion : Our findings suggest that administration of AKBA could exert better chondroprotective and anti-inflammatory effects for MIA-induced osteoarthritis rats.
