Alterations of norepinephrine transporter (NET) function by chroninc inhibition of NET in relation to sensitization to seizures induce by cocaine and local anesthetics were studied. [3H]norepinephrine up take into hippocampus region but not cortex, striatum or amygdalae isolated from mice treated daily for 5 days with desipramine, an inhibitor of NET was significantly decreased. Daily treatment of cocaine increased [3H]norepinephrine uptake into hippocampus. The decrease in norepinephrine uptake induced by chronic desipramine treatment was reversed by co-administration of lidocaine, bupivacaine or tricaine with desipramine. Daily administration of desipramine increased the incidence of appearance of lidocaine-induced convulsions and decreased that of cocaine-induced convulsions. The changes in the convulsive sensitivity to lidocaine and cocaine induced by repeated administration of desipramine was reversed by co-administration of lidocaine with desipramine. These results suggest that down-regulation of hippocampal NET induced by chronic administration of desipramine may be relevant to desipramine-induced sensitization of lidocaine convulsions. Inhibition of Na+ channels by local anesthetics may regulate desipramine-induced down-regulation of NET function. While repeated administration of cocaine caused up-regulation of hipoccampal NET function. Cocaine kindling developed by repeated administration of cocaine may be due to the different mechanisms from those for desipramine-induced sensitization of lidocaine seizures.
