Figure 3: The figure shows I/R value (%), which means the infarct size expressed as percentage of area at risk. Data are expressed as mean ± SEM. *Significantly different (P<0.05) from Group-C, Significantly different (P<0.05) from Group-5- HD-IP, §Significantly different (P<0.05) from Group-5-HD-S. Group-C: a control group (n=9). Group-IP: a ischemia-preconditioned group (n=10). Group-S: a sevoflurane-preconditioned group (n=6). Group-5-HD-IP: a group which was given 5HD 10 min before ischemic preconditioning (n=6). Group-5-HD-S: a group which was given 5HD 10 min before sevoflurane exposure (n=6).
