Plasma 1,3-diaminopropane, putrescine and their conjugates in normal and schizophrenic subjects

ABSTRACT

The levels of free and conjugated 1, 3-diaminopropane and putrescine in human plasma of normal and schizophrenics, are determined by initial purification using cation exchange resin followed by paper chromatography and/or enzymatic analysis. 1, 3-Diaminopropane, putrescine and their conjugates are found in the plasma of schizophrenic patients in concentration higher than in the plasma of normal subjects. The difference between the diamine [free and conjugated] concentrations of normal and schizophrenic subjects were found to be statistically significant
