Methods Fifty adult-male SD rats were equally divided into sham control group 1 IS plus intra-peritoneal physiological saline at 24 48 h after IS group 2 IS plus CsA mg kg at 24h intra-peritoneal group 3 IS plus EPO 5 000IU kg at 24 48h subcutaneous group 4 combined CsA and EPO same route and dosage as groups 3 and 4 treatment group 5 after occlusion of distal left internal carotid artery. Results BIA on day 21 after acute IS was higher in group 2 than in other groups and lowest in group 5 all p . The sensorimotor functional test showed higher frequency of left turning in group 2 than in other groups and lowest in group 5 all p . mRNA and protein expressions of apoptotic markers and number of apoptotic nuclei on TUNEL were higher in group 2 than in other groups and lowest in group 1 and 5 whereas the anti-apoptotic markers exhibited an opposite trend all p . The expressions of inflammatory and oxidized protein were higher in group 2 than in other groups and lowest in group 1 and 5 whereas anti-inflammatory markers showed reversed changes in group 1 and other groups all p . The number of aquaporin-4 and glial fibrillary acid protein .
