Histological features of the experimental pigs. Inflammatory and necrotic foci of liver (a–c), degenerative changes in hepatocytes (d–f) and pulmonary inflammatory foci (g–i) were stained with hematoxylin and eosin. a Liver, pig E in the DS-L group. Focal necrosis of hepatocytes with infiltrated inflammatory cells is evident. b Liver, pig D in the DS-M group. Similar necrotic and inflammatory foci as those shown in Fig. 4a can be seen. Note that these foci are smaller than those of Fig. 4a. c Liver, pig A in the DS-H group. Focally aggregated inflammatory cells without hepatocellular necrosis are shown. Hepatocellular degeneration is also evident. d Liver, pig F in the DS-L group. Mild vacuolar degeneration in a few hepatocytes (arrows) at the periphery of the hepatic lobe are shown. e Liver, pig D in the DS-M group. The stronger degenerative changes (arrows) were more frequently observed than those in Fig. 4d. f Liver, pig A in the DS-H group. Severe hepatocellular hydropic degeneration can be seen throughout the hepatic lobe. CT denotes interlobular connective tissue, and CV denotes the central vein. g Lung, pig E in the DS-L group. Extensive, moderately thickened alveolar wall due to infiltrated inflammatory cells was observed. h Lung, pig C in the DS-M group. The area of thickened wall is smaller than that in Fig. 4g. i Lung, pig A in the DS-H group. Diffuse, apparently normal alveoli and limited wall thickening were observed. Bars in a)–c) and f) represent 50 μm, bars in d) and e) represent 20 μm, and bars in g) and h) represent 200 μm
