Effects of lithium on morphological characteristics of dissociated brain cells in culture

Abstract

Lithium chloride was added in 5 and 10 mM concentrations for different periods of exposition time to dissociated cultures obtained from chicken embryonic brain. When supplementing lithium at day 1 in vitro for five days, a dose-dependent decrease in total protein was observed in the cultures as compared to the sodium-treated controls. Profound reduction was revealed in the length of neuronal processes and in the number of neuronal cell bodies by phase contrast microscopy and by morphometric means. After exposition of lithium in 10 mM concentration for 48 h, beside a slight decrease in number of perikaryons, a marked reduction in process length of neural elements was observed in the 6-day-old tissue cultures. Ultrastructurally, swollen and degenerating nerve processes have been found after lithium treatment suggesting a particular sensitivity of these structures to lithium ion.
