✦ Synopsis
Abstract
The interaction of the inhibitory neurotransmitter γ‐aminobutyric acid (GABA) with erythrocyte membranes from patients with Huntington disease and normal controls has been studied by electron spin resonance. GABA affects the physical state of erythrocyte membrane proteins in control and Huntington disease differently. In addition, after exposure of spin‐labeled Huntington disease erythrocyte membranes to 0.1 mM GABA, the relevant electron spin resonance parameters reflecting the physical state of membrane proteins are indistinguishable from those of untreated control membranes. These findings support the concept that this disease is associated with a generalized membrane defect.

## Abstract The present study focused on the involvement of γ‐aminobutyric acid transporter I (GAT1) in pain. We found that GABA uptake was increased in mouse spinal cord at 20 min and 120 min after formalin injection and in mouse brain at 120 min, but not 20 min, after formalin injection. In addit
In a previous work, we have demonstrated that calcium chelators induce the release of y-aminobutyric acid (GABA) from synaptosomes in a Na+-dependent manner and that this release is blocked by cations such as Mg2+, La3+, and ruthenium red. In the present study, we show that treatment of synaptosomes
## Abstract Erythrocytes are a convenient model to understand oxidative damage to the membranes induced by various xenobiotics. The objective of the present study was to investigate the propensity of atrazine to induce oxidative stress and its possible attenuation by vitamin E. Experimental animals
