Abstract:
Objective:To observe the repairing effect of ozone water injection in the articular cavity for the treatment of knee osteoarthritis (KOA) on articular cartilage and to explore its repair mechanism.Methods:48 rats were randomly divided into fourgroups, the normal, model, normal saline and ozone water group, each group had 12 rats. The rats were injectied into the joint cavity with papain to establish a KOA model other than the normal group. After confirming the success of the model, the ozone water group and normal saline group was treated with ozone water and normal saline injection into the joint cavity once a week for a total of 3 treatments, the normal group and the model group are all raised routinely. Before and after the treatment, the ratknee joint behavioral score MG score was conducted; after the treatment articular cartilage surface gross score, hematoxylin and eosin (HE) staining and modified Mankin score of articular cartilage pathological changes was measured, and Western blot and Rt-PCR to measure the level of protein and mRNA expression of NF-κB p65, IKKβ and IκBα in articular cartilage tissues.Results:Compared with before the treatment, the rat knee joint behavioral score of the ozone water group was significantly lower (all P<0.05); after the treatment, the gross articular cartilage surface score and the modified Mankin score of the ozone water group were significantly reduced compared with the model and normal saline group (all P<0.05); Compared with the model and normal saline group, the protein and mRNA expression levels of NF-κB p65 and IKKβ in the ozone water group are significantly lower (all P<0.05), and the levels of IκBα are significantly higher (all P<0.05). Conclusion:Ozone water injection in the articular cavity can effectively repair damaged articular cartilage. The repair mechanism may be achieved by inhibiting the activation of NF-κB signaling pathway.
