Is cD4 T-lymphocyte activation associated with peak expiratory flow variability in childhood asthma?
CD4 T-lymphocyte activation and increased counts of eosinophils in peripheral blood correlate with CV of PEF in patients with asthma, suggesting that CV of PEF is a good marker for assessing not only the variability of airway obstruction but also the degree of airway inflammation.
Tetrastarch sustains pulmonary gas exchange during experimental systemic inflammation more effectively than saline and pentastarch by protecting the diffusion distance and the size of the microvascular gas exchange surface. Improved capillary perfusion resulting from tetrastarch therapy, which is typically applied to increase blood pressure, may according to the Ohm's law locally decrease hydrostatic perfusion pressures in the pulmonary microvasculature during systemic inflammation.
