Human T cells responding against transplanted allogeneic lung tissue have been implicated in late graft failure secondary to obliterative bronchiolitis. This obliterative airways disease (OAD) also develops in heterotopic murine tracheal allografts in association with graft infiltration by both CD8(+) and CD4(+) T cells. To date, there has been little evidence to suggest that directly alloreact...

Chronic airway rejection is characterized by prolonged inflammation, epithelial damage, and eventual luminal obliterative bronchiolitis (OB). In cardiac allografts, the inducible nitric oxide synthase (iNOS) promotes acute rejection but paradoxically reduces neointimal formation, the hallmark of chronic rejection. The specific roles of NOS isoforms in modulating lymphocyte traffic and airway re...

BACKGROUND Tracheal intubation via laryngoscopy is a fundamental skill, particularly for anaesthesiologists. However, teaching this skill is difficult since direct laryngoscopy allows only one individual to view the larynx during the procedure. The purpose of this study was to determine if video-assisted laryngoscopy improves the effectiveness of tracheal intubation training. METHODS In this ...

background: hemodynamic instability is common during tracheal intubation. the primary purpose of the present study is to evaluate the effect of different doses of remifentanil added to propofol on the hemodynamic profiles during tracheal intubation. methods: ninety patients, 40 to 70 years old, undergoing coronary artery bypass graft surgery under general anesthesia were randomly allocated into...

Mucous secretions were collected from tracheas of patients undergoing minor surgery under general anaesthesia with tracheal intubation, and mucus glycoproteins were isolated by using isopycnic density-gradient centrifugation in CsCl/guanidinium chloride. 'Whole' mucins were excluded from a Sepharose CL-2B gel, whereas subunits obtained after reduction were included. Trypsin digestion of subunit...

BACKGROUND An unanticipated difficult airway may arise during rapid sequence induction and intubation (RSII). The aim of the trial was to assess how rapidly spontaneous ventilation could be re-established after RSII. We hypothesized that the time period from tracheal intubation to spontaneous ventilation would be shorter with rocuronium-sugammadex than with succinylcholine. METHODS This rando...

The use of silicone T tubes for intubation of malignant tracheobronchial strictures may provide some degree of palliation of this distressing condition. It was used in seven patients with malignant lesions and two with benign strictures (resulting from tracheal trauma and lung transplantation). Four patients (two with cancer) are still alive and well with the tube in position. All patients note...

carum carvi (cc) is a grassy plant which is believed to have several therapeutic effects, including anti-asthmatic properties. we have therefore studied the bronchodilatory and anticholinergic effects of this plant. the bronchodilatory effects of the aqueous extract (ae), macerated extract (me), essential oil (eo), and 4µm theophylline (t) in comparison with saline (s) were examined by their re...
