Representative histological lung tissue sections (magnification 400×, hematoxylin and eosin-stained). (A) The samples in the sham group (N = 7) was free of edema and cellular infiltrate. (B) Control group (N = 7). Interstitial edema, type II pneumocyte proliferation and inflammatory cell infiltration in the alveoli and interstitium was detected. (C) Sevoflurane group (N = 7). The lungs of the sevoflurane-treated animals showed almost normal lung architecture and only minor signs of cell influx.
