Abstract
The location of probenecid-sensitive elimination mechanisms of monoamine metabolites from the cerebrospinal fluid of the cat was determined with ventriculo-cisternal or ventriculo-lumbar perfusion techniques. These techniques were described in detail. Levels of endogenous homovanillic acid and 5-hydroxyindoleacetic acid were assayed in the perfusate. Probenecid administration induced the most marked increase of the levels of the monoamine metabolites in the ventriculo-lumbar perfusates. It was concluded that probenecid blocked the transport of both metabolites from the spinal subarachnoid space.
