RESUMO
In order to determine wheter psycopathology is associated with charactheristic neurochemical changes of psychiatric patients, Noradrenergic; Dopaminergic and Serotoninergic urine compounds were quantified in 50 patients (32 females and 18 males) between 20 and 60 years old. They were classified in four groups, according to DSM-IV criteria; in MAJOR DEPRESSION (MD) 30 cases, OBSESSIVE COMPULSIVE DISEASE (OCD) 9 cases, BIPOLAR DEPRESSION (BD)4 cases and SCHIZOPHRENIA (SZ) 7 cases. The following Amine metabolites were determined in 24 hours urine samples Phenylethilamine (PEA); 3-Metho-4-Hidroxy Phenilglycol (MHPG); 5-Hidroxy-indol acetic acid (5HIAA) Homovanilic acid (HVM); Bufotenine (BU); Ometil Bufotenine (OMBU) and 3-5 Metoxy-NN-Dymethyltryptamine (MNNDMT). The results showed a dicrease of Pea levels in 43 per cent of DM; 33 per cent of OCD; 25 per cent of BP and 42 per cent SZ. MOPEG levels were disminished in 53 per cent of DM; 66 per cent of OCD; 25 per cent of BP and 85 per cent of SZ. There was an increase of HVM levels in 10 per cent of DM; 11 per cent of OCD and 25 per cent of BP. There was a dicrease of 5-HIAA levels in 10 per cent of DM while it was increased in 33 per cent and 14 per cent of SZ, BU, OMBU and NNDMT were positive in 71 per cent of SZ; 46 per cent of DM; 55 per cent of OCD and 50 per cent of BP. Our findings are consistent with the hypothesis that PEA; MHPG; 5-HIAA and HVM compounds could be "State markers"of DM and HVM of BP and SZ patients. There is further evidence to support a close interrelationship between the three systems and the urinary excretion of methylates compounds specially in SZ and in DM, OCD and BP patients.
