Subcutaneous injection of 0.5 mg/kg of FK506, 1 h before and 5 h after intra-nasal...

We examined the effect of the immunosuppressive agent, tacrolimus (FK506), on antigen-induced bronchial hyperreactivity to acetylcholine and leukocyte infiltration into the airways of ovalbumin-challenged guinea-pigs. Subcutaneous injection of 0.5 mg/kg of FK506, 1 h before and 5 h after intra-nasal antigen challenge prevented bronchial hyperreactivity to aerosolized acetylcholine, eosinophilia...

Systemic involvement is well known in patients with inflammatory bowel diseases (IBD), but there are only few data looking to Crohn's disease (CD) and ulcerative colitis (UC) separately instead of lumping together both entities to IBD. The frequency of bronchial involvement in UC is not yet exactly analysed but reported to be rare. We asked 100 patients with UC for bronchial complaints, and fou...

A case study of 35-year-old woman with persistent breathlessness and wheezing that had been unsuccessfully treated with inhaled beta 2-agonists and steroids for about two years. Patient developed dry cough and haemoptysis, so investigated further. Spirometry demonstrated a restrictive pattern. Chest CT demonstrated well defined hyperdense lesion in right middle lobe. Biopsy taken from the mass ...

Asthma is characterized by inflammation of the airways that includes eosinophils, basal membrane thickening, epithelial sloughing, vascular changes, smooth muscle hypertrophy and hyperplasia, and mucous gland hyperplasia. Recently, there have been studies on the role of hypersensitivity and inflammation in asthma, but the role of bronchial smooth muscle remains unclear. Bronchial thermoplasty i...

OBJECTIVE In patients with cystic fibrosis, bronchial hyperreactivity is a common finding that has not been conclusively associated with atopy. The objective of the present study was to determine the relationship between chronic colonization or infection with Pseudomonas aeruginosa and bronchial hyperreactivity in a group of patients with cystic fibrosis. PATIENTS AND METHODS A nonspecific hi...
