Objective To explore the relationship of sevoflurane neurotoxicity with the expres-sion of Bid,Bim,Puma.Methods The cortical neuron from newborn SD rat (within 24 h)were see-ded in 6 or 12 well plate,and then randomly divided into 4 groups.Rat culture cortical neurons in vitro exposed in 1%,2%,4% and 0% sevoflurane for 6h were divided into A,B,C and D group. The effect of neuron viability,death and apoptosis were assessed using CCK-8,LDH and caspase-3 cleavage 1 7kDa expression assay.The expressions of Bid,Bim and Puma were assessed by western blot.Results Compared with group D, there were significant increases of neuron death and apoptosis,but a decrease of neuron viability,and upregulated expressions of Bid,Bim and Puma in group B (P <0.05);Compared with group B,Group C had increased death and apoptosis and de-creased viability of neurons,as well as upregulated expressions of Bid,Bim and Puma (P <0.05 ). Conclusion Along with the increase of the concentration,sevoflurane neurotoxicity was increased by upregulation of Bid,Bim,Puma expression.
