Figure 3From: Bioenergetic failure correlates with autophagy and apoptosis in rat liver following silver nanoparticle intraperitoneal administration Histopathological observation of rat liver. Intrahepatic distribution of Ag-nps (A), and histopathological changes in liver tissues at different time points (B) after i.p. injection of Ag-nps. Experiments were carried out as described under Materials and Methods using silver enhancement stain and hematoxylin and eosin stain. A: section thickness was 5-μm. Ag-nps images were taken by optical microscopy with 200× amplifications. B: high magnification of livers (400×).Back to article page
