title: Effect of antidepressants on ATP content, 3H-valine incorporation and cell morphometry of astrocytes cultured from rat brain.
abstract: ATP is a potential marker of cell vialibility and growth. The content of ATP and 3H-valine incorporation into proteins were measured and the morphometry was performed after antidepressant treatment of astrocytes cultured in vitro with or without dibutyryl 3'5'-cyclic adenosine monophosphate (dB-cAMP). Antidepressants were added into the culture medium (for 24 h) at a final concentration of 10(-4)M (imipramine, amitriptyline, clomipramine, doxepine, mianserin) or 10(-5)M (maprotiline). It was shown that all antidepressants except maprotiline and imipramine increased ATP level and decreased 3H-valine incorporation into astrocytes. All drugs except clomipramine and maprotiline, diminished cell area and perimeter of astrocytes. The addition of dB-cAMP to cultures caused an increase of astrocyte form factor. It can be concluded that antidepressants have a significant effect on energy metabolism and differentiation of astrocytes cultured in vitro.
