The effect of superoxide dismutase (SOD) was studied in an experimental arthrosis model (fixation arthrosis in rabbits). Out of a total of 40 animals, 20 of which were to be treated with SOD and 20 with placebos, 5 animals each were given padded stiffened bandages to immobilize their right knee joints for 1 week, 2 weeks, 3 weeks and 4 weeks respectively. After removing the bandage and a two-week recovery period the SOD or placebo treatment respectively was begun. During this period the animals were allowed to move freely. In 20 animals 0.5 mg SOD in 0.2 ml of a 0.5% xylocaine solution were applied intraarticularly in both popliteal spaces once a week for a total of 4 weeks. 20 control animals likewise received 0.2 ml of a 0.5% xylocaine solution (placebo) in both popliteal spaces in the same time intervals. After treatment the animals were killed and examined. A further 5 animals were not given a stiffened bandage, but for 4 weeks they received intraarticular injections once a week of 0.2 ml of a 0.9% saline to act as controls. The evaluation of the changes in the joints was by histological examination and examination by scanning electron microscope. In comparison to the placebo treatment the SOD treatment in this animal experiment did not lead to a significant change in the arthrotic process.
The effect of the enzyme superoxide dismutase (SOD) on experimentally induced osteoarthritis was investigated. Immobilization of the right knee of rabbits over variable periods (1-4 weeks) was used as the model for the study. SOD was applied intraarticularly. Distinct histological changes were detected in the immobilized joints in contrast to the freely mobile joints. In the group of rabbits treated with SOD, erosions, necroses, and inflammatory symptoms were more frequent than in the placebo group. The changes found in animals after SOD application indicate the enzyme has an intensifying effect on osteoarthritis.
