Si. Karas et al., TIME-COURSE OF SEROTONIN IN PLATELETS FROM PATIENTS WITH AFFECTIVE-DISORDERS, Bulletin of experimental biology and medicine, 117(3), 1994, pp. 240-242
Temporal variations in platelet levels of serotonin were found to be s
ignificantly decreased in patients with endogenous affective disorders
, particularly those with the bipolar type of manic-depressive psychos
is. The time course of serotonin content in these cells was not affect
ed by either the sex or the age of the patients. In vitro incubation w
ith Lithium oxybutyrate raised mean platelet serotonin levels and stab
ilized their fluctuation in platelets from healthy subjects but not in
those from the mental patients.
