Abstract:
Twelve non-atopic asthmatic children who were reported to be suffering from exercise-induced asthma (E-IA), and eight non-asthmatic children, were studied in an attempt to discern possible associations between N-alpha-tosyl-L-arginine methyl ester [TAME]-esterase activity and E-IA, and the late asthmatic responses. Lung function tests and clinical examinations were performed at rest, and immediately and four hours after cycling for 6 min. Concomitant blood investigations revealed a consistent elevation in the asthmatics of [TAME]-esterase activity and peripheral blood eosinophil levels, immediately following exercise. Our findings suggest that E-IA is associated with a certain threshold of [TAME]-esterase activity as measured by a simple and a rapid colorimetric method.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
