conclusions these results showed the preventive effect of hydroethanolic extract of n. sativa on tracheal responsiveness of guinea pig model of copd, which was as effective as vitamin c. results the tracheal responsiveness to both methacholine and ovalbumin in guinea pigs with copd were significantly higher than those of controls (p < 0.001 for both cases). the tracheal responsiveness in the co...

STUDY OBJECTIVE This study was undertaken to determine whether tracheal aspirate cultures correlate with protected specimen brush (PSB) cultures in the diagnosis of probable ventilator-associated pneumonia (VAP). DESIGN Retrospective evaluation of 52 episodes of clinical pneumonia in 38 patients who underwent bronchoscopy and PSB as well as tracheal aspirate cultures. SETTING The study took...

Drosophila tracheal terminal branches are plastic and have the capacity to sprout-out projections towards oxygen-starved areas, in a process analogous to mammalian angiogenesis. It was previously shown that this sprouting response involves the upregulation of the FGF homolog Branchless in hypoxic tissues, which binds its receptor Breathless on tracheal cells, thereby attracting the outgrowth of...

OBJECTIVE A fast-track recovery in cardiac surgery yields many benefits, and early tracheal extubation is important as the first step. The purpose of this study is to evaluate the status of early tracheal extubation after on-pump coronary artery bypass grafting (CABG) and to find key factors for successful early tracheal extubation. METHODS From September 1996 to February 2005, isolated on-pu...

Tracheal stenosis is the most common late airway complication of tracheostomy. Severe tracheal stenosis resulted in hemodynamic deterioration and impairment of respiratory system mechanics. We cared for an 86-year-old man with severe tracheal stenosis due to prolonged placement of a tracheostomy tube for 42-months. At the distal tip of the tracheostomy tube, bronchoscopy revealed severe trachea...
