Histological observation of lung injury in the control, L, L + P, H and H + P groups. Lung tissue sections were stained with hematoxylin-eosin. Photomicrographs were taken at 400× magnification. One representative image for each of the lung microscopic photograph in the (a) the control group, (b) the low tidal volume group, (c) the low tidal volume + PKC inhibitors group, (d) the high tidal volume group, (e) the high tidal volume + PKC inhibitors group in three independent experiments is shown. The low tidal volume was 7 ml/kg; the high tidal volume was 42 ml/kg.
