Outline of Final Research Achievements

Rats and mice were mechanically ventilated in lower tidal volume (6mL/Kg) or higher tidal volume (20mL/Kg and 40mL/Kg). Lung was removed and wet/dry ratio and albumin leakage was measured. We found increase in wet/dry ratio and albumin leakage in higher tidal volume group. Lung histology showed immune cell invasion after the mechanical ventilation with higher tidal volume.
Using this model, we investigated the expression of inflammatory cytokine and ERM proteins in the lung. We found that mechanical ventilation with higher tidal volume increased the amount of inflammatory cytokines and decreased the expression of ERM protein in the lung.
These result suggested that the relationship between the expression of ERM protein and the inflammatory reaction after the invasive mechanical ventilation.
