Objectives : This study was designed to evaluate the anti-inflammatory effects of Seungseup-tang (SST) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats.
Methods : Osteoarthritis was induced by injection of MIA (50 ul with 80 mg/ml) into knee joint cavity of rats. Rats were divided into 4 groups (normal group, control group, indomethacin treated group, SST treated group, each n=6). Normal group was not injected with MIA and taken normal diet. Control group was injected with MIA and taken with distilled water. Indomethacin treated group was injected with MIA and taken indomethacin 5 mg/kg by oral administration. SST treated group was injected with MIA and taken SST 200 mg/kg by oral administration. We examined the weight-bearing ability of hind paw, biomarkers related to oxidative stress in serum, inflammatory proteins and inflammatory mediators and cytokines. Moreover, histopathological examination of knee joint structure was also performed by Hematoxylin & Eosin (H&E), Safranin-O staining method.
Results : In the present study, SST treated group showed a similar inhibitory effects alike indomethacin treated group, in most of the studied parameters of inflammation. The increased oxidative stress biomarker such as reactive oxygen species (ROS) and peroxy nitrite (ONOO.) in the serum were reduced with SST. Especially, the level of ONOO. compared with control group significantly suppressed. Also, the expression of inflammatory mediators and cytokines induced by nuclear factor-kappa B (NF-kB) activation was modulated through inhibition of IkBa phosphorlation. In addition, histological analysis revealed that cartilage damage by MIA repaired markedly in SST treated group.
Conclusions : According to the results, Seungseup-tang may be effective for preventing the progression of osteoarthritis. (J
