Abstract
The effects of reserpine and imipramine on the concentration of indolyl compounds bearing an OR group in position 5 (5-OR indolyl compounds) in the cerebrospinal fluid and the caudate nucleus of the dog have been studied. Reserpine was shown to produce an increase in the concentration of these compounds in the cerebrospinal fluid. In the caudate nucleus reserpine produced a fall in the concentration of the basic 5-OR indolyl compounds accompanied by an equivalent increase in the concentration of acidic 5-OR indolyl compounds. No significant change in the concentration of 5-OR indolyl compounds in the cerebrospinal fluid was observed after treatment with imipramine.
