[Measurement of sIgA in patients with chronic stable bronchitis]

As we know secretory IgA of respiratory system has a very important role in defense mechanism. We studied 100 human beings, 50 healthy persons and 50 chronic bronchitis patients. Lavage nasal samples were tacked from healthy persons and sputum samples from chronic bronchitis patients. The laboratory test was nefelometry laser. Samples were analyzed was 1 student. Our results showed light increased of IgA in chronic bronchitis patients not significative. We concluded that this light increased is secondary to continuous stimulus of bronchial mucous as a part of defense mechanism.
