Fig. 6From: Pulmonary effects of inhalation of spark-generated silver nanoparticles in Brown-Norway and Sprague–Dawley ratsDifferential cell counts in bronchoalveolar lavage fluid after inhalation of silver nanoparticles at 1 and 7 days post-inhalation in Sprague Dawley rats (Panels a-d) and in Brown Norway rats (Panels e-h) as a function of lung dose. Data shown as mean ± SD (n = 8–12 rats per group). *P < 0.05, **P < 0.01, ***P < 0.001 versus the Air only control (0) within each time-pointBack to article page
