BCL2 and brain infarction: The major findings were that hydrogen saline could reduce cerebral infarction and improve neurological function in the MCAO rat model, which were mediated by the reduction of oxidative stress (8-OHdG, nitrotyrosine and MDA) and inflammatory factors, and subsequent decrease of neuronal apoptosis (TUENL positive cells, expression of Bcl-2 and Bax, and caspase-3 activity).
