abstract：:Tolerance to nicotine occurs in mice after its chronic administration. This tolerance is accompanied by an up-regulation of nicotinic receptors as assessed by the binding of (3H)-nicotine and alpha-(125I)-bungarotoxin (BTX). Past studies (Marks et al. 1983, 1986) have shown that the increase in BTX binding sites is mo...
