title: [Use of the fluorescent probe method to study the interaction of barbiturates with biological membranes].
abstract: The binding of the negatively charged fluorescence dye ANS and neutral dye NPN2 with lipid and erythrocyte membranes in the presence of barbiturates was studied. It was found that barbiturates decreased the amount of binding sites of ANS and NPN2 with membranes did not affect the quantum yield and the dissociation of the membrane-dye complex. It was shown that all barbiturates investigated were bound with the membranes in a neutral form.
