Inhibition of in vitro production of aldosterone by manic-depressive sera
RP Hullin, MJ Levell, MJ O'Brien and KJ Toumba
Serum samples from psychiatric patients were added to incubations of rat
adrenal cortical cells synthesizing aldosterone. A high proportion of sera
from patients with bipolar manic-depressive psychosis inhibited aldosterone
production, but chronic in-patients without affective disorders gave few
inhibitory sera. Inhibition was greatest in depression, lowest during
normal affect. In one patient studied through 11 affective cycles the
inhibitor score increased during transitions from mania to depression,
showing a significant regression on time. The possible relationship of this
in vitro phenomenon to the defect of aldosterone regulation in
manic-depressive psychosis is discussed.
