The effects of alcohols on RBC membrane fluidity at various concentrations as determined by EPR spectroscopy.

<p>(<b>A</b>) The order parameter (S) of 5-DS-labeled RBC. S for 2 M methanol was 0.729 ± 0.007 (not shown). (<b>B</b>) Rotational correlation time (τ) of 16-DS-labeled RBC. τ for 2 M methanol was 18.20 ± 0.88^** (10^-10 s) (not shown). Data are mean ± SD from 4 experiments on blood samples from different donors. Statistically significant differences compared to control (no alcohol) using one-way ANOVA: * P<0.05, ** P<0.01.
