    Abstract:
    The kinetic and pharmacological characteristics of 3H-spiroperidol binding sites were studied in slide mounted sections of rat forebrain, and optical binding conditions were defined. Using the receptor macroautoradiographic techniques with tritium-sensitive LKB sheet film, the distribution of dopamine (D2) receptor was determined in slices including striatum of rat brain. The autoradiograms were analyzed using Video Digitizer System combined with video camera and minicomputer, and the subtraction images were obtained. These studies suggest that this quantitative receptor macroautoradiography might be useful in the explanation of etiology in the field of neuro-psychiatric diseases and the fundamental studies of positron emission computed tomography, since this method has several advantages over in vivo autoradiography and in vitro receptor assay.
