Abstract
Administration of LiCl (2-4 mmol/kg/day, po) to adult male albino rats for 7 consecutive days increased the catabolism of dopamine (DA) in striatum (ST) and noradrenaline (NA) in hypothalamus (H). Extension of the period of treatment with LiCl (2-4 mmol/kg/day, po) to 14 consecutive days increased catabolism of DA in CX (cerebral cortex) and PM (pons-medulla) and NA in H, and decreased metabolism of DA in ST and NA in PM. Further prolongation of treatment with LiCl (2 or 4 mmol/kg/day, po) for 21 consecutive days greatly affected DA and NA metabolism in the respective brain regions. These results, thus suggest that LiCl produces region specific differential action depending on its dosage and duration of treatment in catecholaminergic activity in rat brain.
