前下小脳動脈結紮による外リンパ遊離アミノ酸の変動について

抄録

The amino acid content of perilymph in the scala tympani of guinea pig was measured by using High Performance Liquid Chromatography. After ligation of one-side anterior inferior cerebellar artery by using ventral surgical approach, the perilymph was collected in both-side via the round window. Animals were divided into three experimental groups; immidiately, one hour later and three hours later after ligation. Both CSF And arterial plasma were collected severally. All the samples were derivertized to the PITC-amino acid and analized the concentrations. Aspartic acid one hour later, and glutamic acid three hours later increased in the ligated side.
