Figure 2: Histological findings ([a and c]: H and E on paraffin embedded sections, ×200, [b and d]: Sudan III staining on frozen sections, ×200). (a) Transparent vacuoles presented changes of string-of-beads in small vessels of lungs and also capillaries of alveolar walls. (b) Fat staining reveals numerous brown fat droplets in the capillaries of alveolar walls. (c) Infiltration of a large number of monocytes and the shedding of Type II epithelial cells were found in alveolus. (d) Fat droplets were found in cytoplasm of monocytes in alveolus with Sudan III staining
