[3H-diazepam binding to brain synaptic membranes during the development of generalized epileptic activity].
The development of bemegride-induced generalized epileptic activity in rats was shown to reduce the constant (CB). of specific 3H-diazepam binding with synaptic membranes from 0.23 nM-1 to 0.15 nM-1 and to increase the maximum number of membrane binding sites (Bmax) from 410 fmol/mg protein to 550 fmol/mg protein. It is assumed that the changes of benzodiazepine receptor properties are due to alteration in physico-chemical characteristics of synaptic membrane lipids resulting from the activation of lipid peroxidation.
