Setup for sampling the production of HO· following spinal cord injury. ACSF containing salicylic acid was perfused through a fiber with its dialysis zone in the site of injury to collect dihydroxybenzoic acids to provide a measure of hydroxyl radical formation. A second microdialysis fiber was passed through the cord 2 cm rostral to the site of injury to provide the basal level of HO· formation. A third fiber was passed directly from the syringe pump supplying the ACSF/DHBA and collecting vials to assess background HO· formation (From de Castro et al., 2004).
