Research Abstract

Free zinc acts as an intracellular messenger in immune cells and thus zinc might be involved in the pathogenesis of respiratory diseases caused by abnormality of immune cells. We tested the effect of zinc chelate agent on asthma and interstitial pneumonia model mouse. Zinc chelate agent could attenuate eosinophilic airway inflammation in ovalbumin induced asthma model mouse, but it was not effective in mite antigen induced asthma model, which might be more similar to human asthma. Additionally, zinc chelate agent was not effective for the treatment of interstitial pneumonia model mouse.
