Abstract: | AIM: IL-1β, IL-6 and TNF-α play important roles in emergence of osteoarthritis. This study aims at observing the effect of the acupotome therapy and electro-acupuncture on the cytokines in serum of rabbits with osteoarthritis. METHODS: 52 New Zealand rabbits were divided randomly into the normal group, model group, acupotome group and electro-acupuncture group. Knee osteoarthritis of the model rabbits was made with the straightened immobilization method. The acupotome and electro-acupuncture therapies were applied for three weeks. One week after the treatment the serum was collected, and the changes of IL-1β, IL-6 and TNF-α in serum were detected with RIA. RESULTS: In comparison with the control group, the contents of IL-1β, IL-6 and TNF-α elevated significantly in the knee osteoarthritis model group (P<0.05). Compared to the knee osteoarthritis model group, the contents of the cytokines in acupotome treatment group and electro-acupuncture treatment group decreased significantly (P<0.05). No significant difference between the content of cytokines in the acupotome treatment or electro-acupuncture treatment groups (P<0.05) was observed, also no statistical difference between the acupotome treatment or electro-cupuncture treatment groups and the control group was found. However, the contents of the three cytokines in the acupotome treatment and electro-acupuncture treatment groups were still higher than those in control group. CONCLUSION: The acupotome and electro-acupuncture treatment can decrease the release of IL-1β, IL-6 and TNF-α, indicating that the two therapies play an important role in improvement of the articular cartilage cell injury and function through inhibiting the generation of matrix protease and alleviation of degradation of the cartilage matrix. |
