This study was designed to look at the effect of N-acetylcysteine (NAC) on epithelial secretory cells and the respiratory tract fluid volume and albumin content from the lower airways of "bronchitic" rats. Rats were exposed either to tobacco smoke (TS), TS and NAC, or NAC alone. TS caused a significant increase in epithelial secretory cell number which was not reduced by concomitant NAC administration; NAC alone had no effect on cell numbers. TS increased respiratory tract fluid volume and albumin content by a small but non-significant amount, whereas TS and NAC increased the volume and albumin content by a greater and significant amount; NAC alone was also shown to significantly increase both fluid volume and albumin content.
