Bone marrow stromal cells combined with oxiracetam influences the expression of B-cell lymphoma 2 in rats with ischemic stroke.
2014
This study aimed to investigate the combination effects of bone marrow stromal cells (BMSCs) and oxiracetam for ischemic stroke. Forty Sprague Dawley female rats (220 ± 20 g) were subjected to a 2-hour ischemic middle cerebral artery occlusion (MCAO)–24 hours reperfusion model. The rats were randomly divided into 4 groups. Rats from BMSCs group, oxiracetam group, and BMSCs + oxiracetam group accepted injection of BMSCs (3 × 10 6 cells), oxiracetam (800 mg/kg), and BMSCs + oxiracetam, respectively. Rats from control group did not receive any interventions after ischemia reperfusion. The neurologic function was examined by modified neurological severity scores (mNSS). B-cell lymphoma 2 (Bcl-2) expression and apoptosis were detected by immunohistochemistry and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining. The mNSS was decreased in all treatment groups and that in BMSCs + oxiracetam group was lower than BMSCs group and oxiracetam group ( P P P P
