Fig. 3From: Intravenous administration of silver nanoparticles causes organ toxicity through intracellular ROS-related loss of inter-endothelial junctionPathological observations for mice received single-dose administration of AgNPs in different diameter or AgNO3. Mice were injected with 25 μg AgNPs or AgNO3 solution containing 2.5 μg Ag. Tissue samples of liver, kidney and lung were collected on 4 h, and 1, 3 or 7 days after the injection. Yellow arrow heads point to inflammatory cells around the hepatic vessels. Blue arrows point to slight fibrous hyperplasia around the blood vessels in the lungBack to article page
