Cerebral infarct volume evaluated by the 2,3,5-triphenyltetrazolium chloride (TTC) assay (A) TTC assay showing that none of the seven rats in the control group exhibited cerebral infarction. (B) In the common carotid artery ligation (CAL) group, seven of the nine rats did not exhibit any cerebral infarct area. However, two rats in the CAL group exhibited small-sized infarct areas in the cerebral cortices, and were excluded from the study.
