HE staining images of cortex (a), hippocampus (b), heart (c), lung (d), liver (e), and kidney (f) in HH-induced mice (× 200 magnification), compared with the control group. a Neurocyte shrinkage and chromatin dissolution. b The number of nerve cells decreased and their arrangement was sparse. c Focal myocardial hyperemia, interstitial capillary hyperemia, massive erythrocyte infiltration, and widening of myocardial space. d Local interstitial hyperplasia, hemorrhage, and extensive red blood cells appeared in alveolar cavity, accompanied by redundant inflammatory cells infiltration. e Central veins of hepatic lobules and hepatic sinus around the central vein, slight swelling of the cells in the marginal zone of hepatic lobule. f Capillary dilatation and congestion, swelling of renal tubular epithelial cells, exfoliation, and separation of basal cells
