Objectives : Mahaengeuigam-Tang (MHEGT) has been used as a traditional medicine for the treatment of rheumatic aerthritis, rheumatisim, eczema and asthma. The aim of this study was to investigate the molecular mechanisms of MHEGT for cartilage protection in monosodium iodoacetate(MIA)-induced osteoarthritis, particularly focusing on apoptosis. Method : Thirty young male Sprague-Dawley rats were used for the study. Rats were intra-articularly injected with 2 mg MIA in a total volume of 50 ㎕ saline. In MHEGT group, MHEGT extract was orally administered once daily to MIA-induced osteoarthritis rats, and rats of control group were given with saline only. At 4 weeks after MIA injection, all animals were sacrificed, and the histological changes and articular thickness were assessed by hematoxylin and eosin staining. Moreover, the immunohistochemical analyses of BAX and Bcl-2 were carried out. Results : The histomorphological examinations revealed that MHEGT reduced MIA-induced cartilage damage. And, MHEGT ameliorated the severity of cartilage surface damages after MIA injection. Furthermore, MHEGT suppressed the MIA-induced increases of pro-apoptotic BAX protein and increased the protein expression of anti-apoptotic Bcl-2 protein. Conclusion : These findings indicate that MHEGT protects against MIA-induced cartilage damage by inhibition of the apoptotic pathway, demonstrating significant protection of cartilage against osteoarthritis. These results suggest that MHEGT may potentially have clinical applications in the treatment of osteoarthritis.
