The table shows the physiological parameters of the rats 1 hour after surgery. There were no changes among groups (P > 0.05) in the measured physiological parameters during the experiment, including MABP, core temperatures, blood gas analysis, and blood glucose. And the table also shows that no rats died in normal, sham-operated control and SBI alone groups. Twelve and 23 of the rats died in DBI and DBI with SBI group respectively. Compared with that in DBI alone group, the mortality of rats in DBI with SBI group was higher (P < 0.05).
