Abstract：
:We describe a simplified HPLC method for the measurement of cocaine and catecholamines in the same brain tissue sample. Using this method to measure cocaine in the brain of rats which received either 10 or 20 mg/kg cocaine injections, we found substantial cocaine concentration differences between medial prefrontal cortex, striatum and limbic brain areas. Specifically, for each cocaine dose level there was a nearly 2-fold differential between cocaine concentration in the cortex as compared to limbic tissue. A shortcoming of many neurobehavioral studies of cocaine effects is the absence of brain cocaine measurements. The simplicity of the present method makes the measurement of cocaine and catecholamines from the same tissue sample a procedure which can readily be incorporated in the studies designed to evaluate the neurochemical effects of cocaine treatments.
