[Several indices of the methylation process in schizophrenic patients].
The paper deals with a study of 83 patients with different forms of schizophrenia and 15 normals where the methylating activity in converting nicotinamid into methylnicotinamid was determined and the activity of catechol-methyltransferase. In schizophrenic patients there is an increase of the methylating activity which significantly correlated with hallucinatory symptoms in the clinical picture. In patients with cataono-paranoid, paranoid syndromes and simple forms of schizophrenia the methylating activity is seen significantly less frequently. The disappearance of alleviation of hallucinations, due to neuroleptical drugs is accompanied by normalization of the methylating activity. Any significant differences in the excretion of isdarin as an index of cathechol-o-methyltransferase activity in normals and schizophrenic patients was not established.
