Pulmonary toxicity of dissolved Zn2+ at 24 h after instillation into lungs of rats. Dissolved Zn2+ in saline was instilled at 92.5 μg/rat. (A - C), cytological analysis of BAL cells. (A), number of total cells; (B), number of PMN; (C), number of eosinophils. Levels of LDH (D) and total protein (E) in the BAL at 24 h after instillation of ZnONP. Values are mean ± S.D. n = 4 for each treatment group. Significance versus vehicle control (VEH): * p < 0.05, ** p < 0.01, # p < 0.001. Zn2+ (92.5 μg/rat) was compared with ZnONP at 50 cm2/rat: $ p < 0.05.
