Our results show the presence of a substance which inhibits the 3H-fiunitrazepam binding specifically in the samples taken from the patients? groups, and which is not present in normal controls, in the range of concentrations used. This compound has a molecular weight below 1,000 daltons, is heat-stable, and resistant to proteolytic degradation. The demonstration of this inhibitor opens new perspectives in the study of the biochemistry of anxiety.} }
