Objectives: This study was carried out to investigate the protective effects of Jeungmiobi-tang on the articular cartilage injuries induced by monosodium iodoacetate in rats. Methods: Twenty four rats were divided into three groups. Rats of normal group (n=8) were injected with 0.1 ml physiological saline into both knee joint cavities. In the rats of control group (n=8) and Jeungmiobi-tang group (n=8), Arthritis was induced by injecting with 0.1 ml monosodium iodoacetate (5 mg/ml) into both knee joint cavities. After the experiment, Gross and histopathological examinations on the knee joint were performed. The content of proteoglycan in articular cartilage and TNF-α and IL-1β in synovial fluid were also analyzed. Results: Grossly, Injuries to the articular cartilage surface was observed weak in the Jeungmiobi-tang group compared to the control group. Proteoglycan content in the articular cartilage was significantly higher in the Jeungmiobi-tang group than in the control group. The chondrocyte score was significantly lower in the Jeungmiobi-tang group than in the control group. Conclusion: According to these results, that Jeungmiobi-tang has protective effects on the articular cartilage injuries induced by monosodium iodoacetate in rats.
