Abstract | BACKGROUND/PURPOSE: METHODS: Rats were randomly divided into four groups: sham; MCAO without HBO2 treatment; MCAO treated with 1-day trial of HBO2; and MCAO treated with 2-4-day trials of HBO2. One treatment of HBO2 (100% O2 at 253 kPa) lasted for 1 hour in a hyperbaric chamber. RESULTS:
Therapy with the 2-4-day trials of HBO2 significantly and dose-dependently attenuated the MCAO-induced cerebral infarction and neurological deficits more than the 1-day trial of HBO2 therapy. The beneficial effects of repetitive HBO2 therapy were associated with: (1) reduced inflammatory status in ischemic brain tissues (evidenced by decreased levels of tumor necrosis factor-α, interleukin-1β, and myeloperoxidase activity); (2) decreased oxidative damage in ischemic brain tissues (evidenced by decreased levels of reactive oxygen and nitrogen species, lipid peroxidation, and enzymatic pro-oxidants, but increased levels of enzymatic antioxidant defenses); and (3) increased production of an anti-inflammatory cytokine, interleukin-10. CONCLUSION:
