Abstract:
:Penicillin (PC) neurotoxicity (convulsions and encephalopathy) is considered to be due to GABAergic inhibition. The effects of penicillin G(PCG) on [3H]flunitrazepam (FNZ) binding in rat neuron-enriched primary cultures was examined to assess the role of the benzodiazepine (BDZ) receptor in the neurotoxicity. PCG application for 24 h induced a significant decrease in [3H]FNZ binding activity at 10(-3) M, and a decrease in available receptor number (Bmax) at 10(-2) M, without obvious cell damage. Pre-application of the BDZ receptor antagonist, Ro-15-1788, prevented the PC-induced decrease in [3H]FNZ binding activity. Therefore, PC seems to reduce the number of BDZ receptors through a direct effect on this receptor, which is a part of the major inhibitory system in mammalian brain; the GABAergic macromolecular receptor complex. This decrease in BDZ receptors may play a role in PC-induced neurotoxicity, especially encephalopathy.
