Popis: We investigated whether mild hypothermia combined with sodium hydrosulfide treatment during resuscitation improves neuron survival following cerebral ischemia-reperfusion injury beyond that observed for the individual treatments. Male Sprague-Dawley rats were divided into seven groups (n = 20 for each group). All rats underwent Pulsinelli 4-vessel occlusion. Ischemia was induced for 15 min using ligatures around the common carotid arteries, except for the sham group. Immediately after initiating reperfusion, the mild hypothermia (MH), sodium hydrosulfide (NaHS), hydroxylamine (HA), MH + NaHS, MH + HA, and ischemia-reperfusion (I/R) control groups received an intraperitoneal injection of saline, sodium hydrosulfide, hydroxylamine, sodium hydrosulfide, hydroxylamine, and saline, respectively, and mild hypothermia (32 to 33 °C) was induced in the MH, MH + NaHS, and MH + HA groups for 6 h. The levels of NR2A, NR2B, p-Akt, and p-Gsk-3β in the hippocampus of the MH, NaHS, and MH + NaHS groups were higher than those in the I/R control group, with the highest levels observed in the MH + NaHS group (P
