title: CSF beta-endorphin-immunoreactivity in normal, schizophrenic, depressed, manic and anorexic subjects.
abstract: beta-Endorphin immunoreactivity was measured in cerebrospinal fluid of 75 medication-free subjects: normal, depressed, schizophrenic, and anorexic. No significant differences in beta-endorphin immunoreactivity were found. Affinity extraction chromatography revealed beta-lipotropin and beta-endorphin, but no apparent precursors.
