Figure 4: Values of malondialdehyde, superoxide dismutase glutathione peroxidase, glutathione reductase, and catalase in the homogenates of the ischemic for the sham-operated ((b) first column), 37°C saline-treated FPI rats ((b) second column), and 4°C saline-treated FPI rats ((b) third column) rats. The isotonic sodium chloride solutions were administered via the jugular vein 3 minutes after the onset of FPI. The FPI-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-injured group.
