Objectives This study was designed to evaluate the healing effect of Cordyceps Militaris (CM) on collagen II-induced arthritis rats.
Methods Sprague-Dawley rats were randomly divided into 6 groups (normal, control, positive control, CM with low/medium/high dosage each). Type II collagen mixed with complete Freund's adjuvant (with 1:1 v/v) was injected subcutaneously, and the mixture was injected in a same manner one week after the first injection to boost arthritis.
Arthritis index, paw thickness and von Frey test were conducted to observe physical changes. hematoxylin and eosin (H&E) staining was performed to observe knee cartilage. The levels of messenger RNA (mRNA) expressions of interleukin (IL)-1β, IL-6, tumor necrosis factor-alpha (TNF-α) in spleen were assessed by real-time polymerase chain reaction.
Results Rheumatoid arthritis is an autoimmune disease that occurs on multiple joints and can lead to temporary shape change of bones or organ failure in severe cases.
Here, we aimed to determine the effect of CM extract on rheumatoid arthritis by measuring paw thickness, arthritis index, conducting von Frey test and H&E staining, and evaluating the level of IL-1β, IL-6, TNF-α. As a result, paw thickness, arthritis index significantly decreased in low concentration group, hind leg became less sensitive in all expermental groups. Also, histological analysis showed that the damage of knee cartilage was prevented in all experimental groups. The level of mRNA of IL-1β, IL-6, and TNF-α in spleen was analyzed to decide the effectiveness of CM extract. IL-1β did not show significant change, but IL-6 and TNF-α showed significant decrease in at least one of the experimental groups.
Conclusions CM showed protective effect on knee tissue destruction and improved the physical conditions of the leg involving arthritis. Also, it showed that CM has anti- inflammatory effect on specific cytokines inducing rheumatoid arthritis. In conclusion, this study demonstrated that the therapeutic potential of CM for the treatment rheumatoid arthritis, and set the foundation for the further studies.
