ABSTRACT

BACKGROUND:Temporomandibular joint osteoarthritis can cause severe pain,which significantly affects the patient's quality of life and psychological health.Studies have found that medical ozone can effectively alleviate pain due to temporomandibular joint osteoarthritis,but its analgesic effect and mechanism are still unclear. OBJECTIVE:To explore the effects of medical ozone on pain relief in temporomandibular joint osteoarthritis and the potential mechanisms. METHODS:Twenty-four Sprague-Dawley rats were randomly divided into four groups(n=6 per group):control group,model group,air group,and medical ozone group.A sodium iodate-induced rat model of temporomandibular joint osteoarthritis was established in all groups except for the control group.After 1 week of modeling,rats in the air group and medical ozone group were injected with clean air and medical ozone,respectively,in the temporomandibular joint.The injection frequency for the air group and medical ozone group was once a week for three times in total.The von Frey mechanized pain measurement technique was used to assess the mechanical pain threshold of the temporomandibular joint in rats before and 28 days after modeling.ELISA was utilized to detect interleukin-1β in both serum and temporomandibular joint fluid at 28 days after modeling.Histopathologic changes of the temporomandibular joint were evaluated through hematoxylin-eosin staining.Additionally,the expression levels of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joint were analyzed using immunohistochemistry. RESULTS AND CONCLUSION:Compared with the control group,the mechanical pain thresholds of the temporomandibular joint in the model group were decreased at 1,3,7,14,21,and 28 days after modeling(P<0.01);and compared with the model and air groups,the mechanical pain thresholds of the temporomandibular joint in the medical ozone group were increased at 28 days after modeling(P<0.01).Compared with the control group,the level of interleukin 1β in the serum and joint fluid of rats in the model group was elevated(P<0.01);compared with the model and air groups,the level of interleukin 1β in the serum and joint fluid of rats in the medical ozone group was decreased(P<0.01).Hematoxylin-eosin staining results showed derangement and degeneration of the cartilage structure in the model group and the air group,while the derangement of the cartilage structure in the medical ozone group was less than that in the model group and the air group.Immunohistochemical staining showed that the expression of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joints of rats in the model group was elevated compared with that in the control group(P<0.01);the expression of hypoxia-inducible factor 1α and cyclooxygenase 2 in the temporomandibular joints of rats in the medical ozone group was decreased compared with that in the model group and the air group(P<0.01,P<0.05).These findings suggest that medical ozone can alleviate the pain caused by osteoarthritis of the temporomandibular joints in Sprague-Dawley rats by reducing the expression of hypoxia-inducible factor 1α,interleukin 1β,and cyclooxygenase 2.

ABSTRACT

Objective To compare the variations of serum cytokines before and after ozone injection with different dosages and between intra-articular injection of knee joint and autohemotransfusion injection in experimental rabbits,to make a further understanding of the biologic mechanism of ozone therapy on osteoarthritis(OA).Methods Thirty-six New Zealand white rabbits were equally and randomly divided into six groups:(1) normal group,(2) OA model group,receiving no treatment,(3) group L10,receiving 10 ?g/ml ozone per intra-articular injection,(4) group L30,receiving 30 ?g/ml ozone per intra-articular injection,(5) group S10,receiving autohemotransfusion with 10 ?g / ml of ozonized blood per injection and(6) group S30,receiving autohemotransfusion with 30 ?g/ml of ozonized blood per injection.OA models were prepared by injecting 0.5 ml of collagenase II solution into the knee joint space two times with an interval of three days.Blood samples of all groups were collected 4 weeks after the last ozone treatment for further analysis.Serum levels of NO,T-SOD,TNF-? and IL-1? were estimated.Results The serum levels of NO,T-SOD,TNF-? and IL-1? in the model group and all treated groups were significantly higher than that in normal group(P0.05).Conclusion(1) An increase in the serum levels of NO,T-SOD,TNF-? and IL-1? exists in rabbit OA models.(2) Ozone has no inhibitary effect on the serum levels of NO,T-SOD,TNF-? and IL-1?,regardless of what route of administration of ozone is adopted.(3) The effect of "oxidative preconditioning" is not local,but rather systemic.
