The effects of inhaled beclomethasone dipropionate (BDP) on asthma symptoms and infiltration of the bronchial mucosa by inflammatory cells were investigated in an open study of 10 patients with mild-to-moderate nonatopic bronchial asthma. Asthma scores were recorded in an asthma diary. Peak expiratory flow (PEF), PEF diurnal variation (PEF%), forced expiratory volume in one second (FEV1%), methacholine airway hypersensitivity (minimum dose of methacholine) (Dmin) were measured. Biopsy of the bronchial mucosa was performed before and after 8 weeks of treatment with BDP (400 micrograms.day-1). The following inflammatory cells were immunostained: eosinophils with anti-EG2; mast cells with AA1; neutrophils with NP57; T-lymphocytes with anti-CD3, CD4, and CD8; and activated T-lymphocytes with anti-CD25. There was a significant improvement in the asthma symptom score, PEF%, FEV1%, and Dmin after BDP therapy and the number of EG2-, AA1-, CD3-, CD4-, and CD25-positive cells decreased significantly. We conclude that inhaled beclomethasone dipropionate inhibited inflammatory cell infiltration of airway tissue and that associated with this there was an improvement of symptoms in this open study of inhaled beclomethasone dipropionate in a group of nonatopic asthmatic subjects.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008407	Mast Cells	Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.	Basophils, Tissue,Basophil, Tissue,Cell, Mast,Cells, Mast,Mast Cell,Tissue Basophil,Tissue Basophils
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009092	Mucous Membrane	An EPITHELIUM with MUCUS-secreting cells, such as GOBLET CELLS. It forms the lining of many body cavities, such as the DIGESTIVE TRACT, the RESPIRATORY TRACT, and the reproductive tract. Mucosa, rich in blood and lymph vessels, comprises an inner epithelium, a middle layer (lamina propria) of loose CONNECTIVE TISSUE, and an outer layer (muscularis mucosae) of SMOOTH MUSCLE CELLS that separates the mucosa from submucosa.

D001980	Bronchi	The larger air passages of the lungs arising from the terminal bifurcation of the TRACHEA.

D001985	Bronchial Provocation Tests	Tests involving inhalation of allergens (nebulized or in dust form), nebulized pharmacologically active solutions (e.g., histamine, methacholine), or control solutions, followed by assessment of respiratory function. These tests are used in the diagnosis of asthma.
