ALA attenuated MCAO/R-induced neuronal apoptosis. (a) DNA fragmentation in apoptotic neuronal cells was detected by TUNEL; arrows represent TUNEL-positive cells; bar = 50 μm. (c) Quantitative analysis of TUNEL-positive cells rate. For the ALA + MCAO/R group, ALA (40 mg/kg, i.p.) was daily administered to rats for 3 days. For the sham and MCAO/R groups, the rats were given the same amount of ethanol. Data were expressed as means ± SEM. ## compared with the sham group. compared with the MCAO/R group.
