Figure 3.

Interstitial inflammation in the myocardium. Results are shown in non-septic non-ventilated rats (no sepsis; n = 8), non-ventilated sepsis rats (sepsis; n = 8), rats ventilated with low tidal volume (sepsis + LTV; n = 10), and rats ventilated with high tidal volume (sepsis + HTV; n = 10). Upper panel depicts the number of macrophages, middle panel represents the number of polymorphonuclear leukocytes, and the lower panel represents the number of lymphocytes. HTV = high tidal volume; LV = left ventricle; LTV = low tidal volume; MV = mechanical ventilation; RV = right ventricle. * P < 0.05.
