摘要: Abstract After isolation and separation on columns of Sephadex G10, 5-hydroxyindole-acetic acid, homovanillic acid 3-methoxy-4-hydroxyphenylglycol from human lumbar cerebrospinal fluid was measured fluorimetrically. Details about fluorimetry the glycol are given. The effect intravenously administered probenecid levels three compounds in CSF investigated as a function time. acids, 5-hydroxyindoleacetic accumulated not earlier than 6 hr after administration drug. noradrenaline metabolite, 3-methoxy-4-hydroxy-phenylglycol, did accumulate under influence probenecid. lag phase 4 before accumulation acids occurs, might reflect transport time along spinal cord cisteraal- to region.
