| Outline of Final Research Achievements |
Study I: Rats were divided into young and aged group. Then, each group was subdivided into control, general anesthesia without surgery, and general anesthesia with surgery group. All rats except those in the control group were anesthetized for 1 h with 2% sevofurane and 33% oxygen. In the control group, both the young and aged controls acquired spatial memory in Morris Water Maze. Both anesthesia with and without surgery impaired spatial learning in aged rats but not in young rats.
Study II: We divided rats into just after sevoflurane, 7 days after sevoflurane and the control group. Rats were anesthetized with 2% sevoflurane, 33% oxygen for 2 h in the group sevoflurane. The brain was observed in a transmission electron microscope. Some degeneration cells were found in the sevoflurane groups. We found angiogenesis 7 days after sevoflurane anesthesia. Angiogenesis is likely to be induced in the restoration process of the degenerated brain cells caused by sevoflurane anesthesia.
