[Analysis of the specific 3H-diazepam binding in the brain of inbred mice with differing emotionality].
The influence of sodium chloride and gamma-aminobutyric acid (GABA) on H3-diazepam binding in CNS membrane fraction were investigated in C57Bl/6, BALB/c mice and their F1 hybrids. The addition of GABA (1, 10 and 100 microM) elevated the level of radioligand binding with CNS membranes in all the inbred mice in similar manner. The higher stimulating effect of sodium chloride (50, 100 and 150 mM) on the H3-diazepam reception was found in BALB/c mice and F1 hybrids, as compared to C57Bl/6 mice. It has been suggested that membrane-dependent conformational reconstructions of supramolecular receptor complex are the cause of genetic differences in the regulation of H3-diazepam reception by Cl(-)-ionophore.
