Central norepinephrine metabolism in affective illness: MHPG in the cerebrospinal fluid.

Concentrations of the norepinephrine metabolite 3-methoxy-4-hydroxyphenyl glycol in cerebrospinal fluid were measured by a gas chromatographic method in 34 patients with affective illness and in 44 controls. Concentrations of this metabolite in spinal fluid were significantly lower in depressed patients than in controls or manic patients. These low values may occur secondary to depressive phenomena such as reduced psychomotor activity, or they may reflect a primary change in norepinephrine metabolism in depressive illness.

Amine metabolites in human cerebrospinal fluid: effects of cord transection and spinal fluid block.

Patients with spinal cord transection had normal concentrations of 5-hydroxyindoleacetic acid and low concentrations of 3-methoxy-4-hydroxyphenyl glycol in lumbar cerebrospinal fluid. The presence or absence of spinal fluid block in these patients did not affect concentrations of either amine metabolite. However, the concentration of homovanillic acid was lower in patients with spinal fluid block than in those without block. The results suggest that the spinal cord contributes to concentrations of 3-methoxy-4-hydroxyphenyl glycol and possibly 5-hydroxyindoleacetic acid, but contributes little to that of homovanillic acid in the lumbar spinal fluid of man.
