title: Correlation between drug induced changes of acetylcholine release and acetylcholine fractions in rat brain.
abstract: After administration of eserine, a new acetylcholine (ACh) subfraction called f+ is formed in rat brain tissue. References and methods are given for the calculation of this subfraction, which can be isolated and determined only together with the so-called "free" ACh fraction. Alterations of the f+-ACh subfraction caused by barbital, urethane, pentetrazol, arecoline and scopolamine in telencephalon, cortex and striatum of rat brain are connected with changes of ACh concentrations determined in comparable releasing tests.
