Characterization of divalent cation-induced [3H]acetylcholine release from EGTA-treated rat hippocampal synaptosomes.

abstract：:Mitochondrially bound brain hexokinase is solubilized by anesthetics and this effect has been suggested to contribute to anesthesia. In the present investigation the influence of the metabolic inhibitor 2-deoxy-D-glucose (2-DOG) was studied. An isolated rat brain preparation was used to avoid the contribution of perip...
