Effect of long-term Al feeding on the fluidity of the myelin membrane.

Parameter	Control	Al-fed
Fluorescense Polarization, P	0.254 ± 0.008	0.260 ± 0.003
Fluorescense anisotropy, r	0.186 ± 0.006	0.190 ± 0.002
Limited hindered anisotropy, rα	0.148 ± 0.008	0.153 ± 0.003
Order parameter, S	0.612 ± 0.006	0.622 ± 0.002

The experimental details are as given in the text and in Table 1. Fluidity parameters were determined at 25°C within 2–3 hr of myelin membrane preparation using DPH as the probe[30,47]. Results are given as mean ± SEM of 18 observations in each group.
