Relation of Sex and Aging to Monoamine Oxidase Activity of Human Brain, Plasma, and Platelets

Robinson, Donald S.·1971·Archives of General Psychiatry

Abstract

Monoamine oxidase (MAO) activity was determined in blood from 113 normal subjects ranging from 21 to 84 years of age and in hindbrain obtained at autopsy from 26 patients. MAO activity correlated highly with increasing age for all three sources of enzyme studied (hindbrain, plasma, and platelets). Women were found to have significantly higher mean platelet and plasma MAO activity than men. The tendency for greater MAO activity in women and with aging is intriguing because it is consistent with clinical observations about the incidence of depressive illness. Increased enzyme activity related to aging and sex may be a biologic factor that, in association with Psychological and social stresses, predisposes certain individuals to the development of depression.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
