STUDY OBJECTIVE Our objective was to compare the differential effects of age and drug type on bronchodilator response. DESIGN The design was an unblinded, randomized crossover study. SETTING An ambulatory pulmonary drug study unit was the setting. PATIENTS Nineteen young (18 to 25 yr) and 17 elderly (greater than 65 yr) stable asthmatic subjects were studied. INTERVENTIONS AND MEASUREME...

Bronchial asthma is a chronic inflammatory disease of the lung by combined action various cytokines. As result strong response increased infiltration cytokines result, damages respiratory epithelium, Hyperplasia trachealis muscle, and mucous production. Athimathura choornam promising drug used in all conditions. Objective: To explore efficacy Siddha formulation choornam, an anti asthmatic using...

The effects of deep inspiration upon expiratory flow rates and response to inhaled metaproterenol were studied in normal and asthmatic subjects using partial (PEFV) and maximal (MEFV) expiratory flow volume curves. Routine pulmonary function tests and specific conductance were also measured. Prior to administration of metaproterenol, 18 of 24 normal subjects and 11 of 24 asthmatic subjects (p 0...

BACKGROUND It has been suggested that the presence of Toxocara canis larvae in lungs is an underlying factor in the onset of asthma. Although the association of asthma and seropositivity to Toxocara has been observed, there are no studies that indicate whether these antibodies are specific against T. canis antigens. METHODS Seroprevalence to T. canis excretion-secretion antigens (TcES Ag) wer...

backgroundasthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. we aimed to investigate right ventricular (rv) functions in asthmatic children by conventional and tissue doppler echocardiography (tde).materials and methods pulmonary function tests, con...
