試験には、7週齢のWistar系雄性ラットを1群10例で用いた。麻酔下のラットを脳定位固定装置に固定し、頭蓋骨を露出させてBregmaより後方1.4mm、正中線の左右2.8mmの位置2カ所に小骨窓を開けた。露出した硬膜より腹位7.6mmの大脳基底核にカテーテルを挿入し、5μgのイボテン酸を0.5μLのリン酸緩衝液(50mM)に溶かしたイボテン酸溶液を5分間かけて注入して大脳基底核を破壊処置し、アルツハイマー病モデルラットを作製した。なお、偽手術群のラットには、イボテン酸溶液に代えて0.5μLのリン酸緩衝液(50mM)を注入した。大脳皮質に投射しているアセチルコリン神経の起始核であって、学習・記憶機能にきわめて重要な役割を果たす大脳基底核を破壊されたラットは、大脳皮質でのアセチルコリン神経の機能異常によって学習・記憶機能に障害が生じることが知られている(Shinodaら、Behav.
