Figure 6: Values of the amounts of 3-nitro-L-tyrosine of glutathione peroxidase positive cells in the ischemic cortex for the sham-operated rats (first column), 37°C saline-treated FPI-treated rats (second column), and 4°C saline-treated-FPI-treated (third column) rats. The isotonic sodium chloride solutions were administered via the jugular vein 3 minutes after the onset of FPI. The PFI-injured rats were killed on day 3 after surgery. Values are mean ± SEM; per group. * versus sham-operated controls; † versus 37°C saline-treated FPI-treated group.
