Abstract: Objective To evaluate the effect of sevoflurane on cognitive function of mice with Alzheimer's disease.Methods Twenty male mice carrying mnutations in amyloid precusor protein (APP) and presenilin 1 genes,weighing 30-40 g,aged 7 months,were divided into either sevoflurane group (group Sev) or control group (group C),with 20 mice in each group.Mice inhaled 3％ sevoflurane for 4 h in group Sev,and mice inhaled 30％ oxygen for 4 h in group C.At 1 month after inhaling sevoflurane or oxygen,the mice underwent continuous multiple-trail inhibitory avoidance training.The mice were then sacrificed and hippocampi were isolated for determination of the number of Aβ plaques (by immunohistochemistry) and expression of APP and Tau (S396) phosphorylation (by Western blot).Results Compared with group C,the memory lateucy was significantly shortened,the number of Aβ plaques was increased,the phosphorylation of Tau (S396) was increased,and the expression of APP was up-regulated in group Sev (P＜0.05).Conclusion Sevoflurane can decrease the cognitive function of mice with Alzheimer's disease.
