Key mediators in the immunopathogenesis of allergic asthma

Immunopathogenesis of Allergic Asthma: More Than the Th2 Hypothesis

Asthma is a chronic obstructive airway disease that involves inflammation of the respiratory tract. Biological contaminants in indoor air can induce innate and adaptive immune responses and inflammation, resulting in asthma pathology. Epidemiologic surveys indicate that the prevalence of asthma is higher in developed countries than in developing countries. The prevalence of asthma in Korea has ...

Mediators of Allergic Asthma and Rhinosinusitis

Induction of experimental allergic asthma in cat

19 cats were nper-sensitized to allergic asthma by receiving a concomitant spray ang injection of ovalbumin (10% fresh egg-white in normal saline) every other days for four weeks.then animals were anesthetized and left femoral artery cannulation performed to record atrerial pressure and take blood samples.left femoral vein was cannulated to infuse nutritional fluids and grugs as needed.trachea ...

Trace Elements Status in Sera of Patients with Allergic Asthma

Background: Asthma is a multifactorial disease and its severity varies with the inflammatory grade. There are conflicting reports about the roles of trace elements in asthma. This study examined the effects of zinc (Zn), copper (Cu), and selenium (Se) concentrations in sera of patients with allergic asthma attending Ghaem Hospital, Mashhad, Iran. Methods: Forty-nine patients, aged 10 to 50 y...

General overview of fungal allergic asthma

Asthma is a complicated disorder, whose prevalence has increased over the past few decades.Asthma is characterized by infiltration of inflammatory leukocytes along with enhancedproinflammatory cytokines and chemokines. Fungi are now far more widely being considered as thedominant extrinsic trigger for asthma. Fungi are linked to the severity of asthma in many ways. Somedifferences between studi...
