Figure 4.

Accumulation of inflammatory cells in liver sinusoids. Representative centrolobular parts of liver tissue sections stained with haematoxylin and eosin are shown as low-power fields (a,b) and high-power fields (c,d) of the same area (optical magnification of microscope × 10 and × 40). (a,c) Animal from the PCV group. Few inflammatory cells are shown. (b,d) Animal from the PCV+R group. Infiltration of polymorphonuclear neutrophils and lymphocytes in the sinusoidal area of the liver is shown. PCV, pressure-controlled ventilation; PCV+R, pressure-controlled ventilation with recruitment manoeuvre.
