Abstract
Studies have shown that long-term exposure to sevoflurane (SEV) may cause postoperative cognitive dysfunction. This study aimed to investigate the effects of resveratrol (RES) treatment on the changes in the cognitive function of rats after prolonged anesthesia with SEV. Seventy-six adult male rats were used in this study. The SEV model was established under continuous anesthesia for 6 h. Rats were randomly classified into four groups as follows: control, SEV+vehicle, SEV+pre-RES (RES was administered 24 h before establishing the SEV model), and SEV+post-RES (RES was administered 1 h after establishing the SEV model) groups. Neurobehavioral outcomes and the potential mechanism underlying RES-mediated neuroprotection through the SIRT1/RhoA signaling pathway were evaluated. The water maze test showed that long-term exposure to SEV may lead to loss of learning and memory ability in rats (ppp0.05). Western blotting showed that SIRT1, RhoA, and cleaved Caspase-3 (CC3) expression significantly increased in the SEV+vehicle group (pp<0.05). In conclusion, RES treatment improved cognitive dysfunction by reducing neuronal apoptosis in adult rats exposed to SEV. RES partly exerted a neuroprotective effect through the activation of the SIRT1/RhoA signaling pathway.Keywords
