“…Bufotenine was also found in the urine of schizophrenics given a MAOI alone (Heller, 1966) or in conjunction with betaine , or cysteine (Spaide et al, 1968). However, other workers could not find bufotenine in the urine of schizophrenics (Rodnight, 1956;Sprince et al, 1963;Siegel, 1965;Nishimura and Gjessing, 1965;Kakimoto et al, 1967), or could find it only in medicated and not in unmedicated schizophrenics (Runge et al, 1966). On the other hand, other workers found bufotenine in schizophrenics but also in normals (Perry et al, 1966;Gross and Fransen, 1964;Faurbye and Pind, 1968), mental defectives (Tanimukai et al, 1967), and autistic children and their relatives .…”
