title: Biochemical RBC abnormalities in drug-free and lithium-treated manic patients.
abstract: RBCs from two lithium-free manic patients displayed lower choline transport and higher choline concentrations and methionine S-adenosyltransferase activity than those of controls. Lithium therapy decreased RBC methionine S-adenosyltransferase activity to normal, decreased choline transport further, and increased choline concentrations further.
