“…For example, MAO-B activity in platelets is significantly altered in psychiatric patients as a consequence of treatment with neuroleptics (Baron et al, 1982;Chojnacki et al, 1981) and lithium salts (Bockar et al, 1974;Chojnacki et al, 1981;Huang et al, 1984). Moreover, an association between MAO activity and ethanol consumption has been proposed by several investigators (Aliyu and Upahi, 1988;Anokhina et al, 1990;Nevo and Parvez, 1994;Tabakoff et al, 1985). Presently, nothing is known about the mechanism for these changes in enzyme activity.…”
