Normalized regional cerebral blood flow (rCBF, %) at different time points in relation to the onset of transient MCAO with MEA pretreatment in the study on tissue apoptosis in the right cerebral hemisphere of the rats.

Group (number of rats)	Before MCAO	Onset of MCAO	30 min after MCAO	60 min after MCAO	Onset of reperfusion	30 min after reperfusion
Control (5)	100	24.6 ± 1.6	25.5 ± 1.5	27.2 ± 1.7	96.5 ± 6.2	98.0 ± 5.5
MEA (5)	100	23.3 ± 2.1	24.4 ± 1.9	26.2 ± 2.3	104.3 ± 6.8	102.1 ± 10.2

Data are expressed as mean ± SEM. Normalized rCBF dropped to less than 30% during transient MCAO and returned to more than 70% at the onset of reperfusion. There was no statistically significant difference between the control and MEA groups at the same time points (P > 0.05).
