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.
