The effect of ozone treatment in experimental rat gout arthritis was investigated. Twenty adult albino male rats were divided into 4 groups: Group 1 (Control) was followed without any medication, Group 2 (Gout control) was injected with a single dose of 0.2 mL (10 mg) monosodium urate (MSU) intraarticulary to 1st metatarsophalangeal joint to create experimental Gouty arthritis. Group 3 (Gout + Ozone) was injected intraarticulary to 1st metatarsophalangeal joint with a single dose of 0.2 mL (10 mg) MSU to generate experimental gout, followed by ozone therapy to the rats a single dose of 1 mL (10 mu g/mL) intraperitoneally daily for 3 weeks. The Group 4 (Ozone control) ozone therapy was given a single dose of 1 mL (10 mu g/mL) intraperitoneally daily for 3 weeks without gout formation. The results were recorded and compared statistically between the groups. In conclusion, the low level of inflammation in the third group (Gout + Ozone) was considered statistically significant as compared to the second group. With Ozone treatment the gout joint has been shown to have reduced acute inflammation, it has not been affected by the chronic proliferation process.
