The effect of lung antibody on normal lung structure and function.

The effects of repeated passive immunization of normal mice with homologously derived mouse lung antibody during a 9-week period were studied. Although the antisera were not acutely pneumotoxic, pathologic changes resulted. The antibody was found to localize in focal areas on the alveolar septa as evidenced by immunofluorescence and to cause a monocytic infiltrate and necrosis of the lung as evidenced by increases in lactic dehydrogenase isoenzymes 2 and 3. After 4 weeks of treatment, the animals showed distension of the airways distal to the terminal bronchioles, increased interstitial alveolar connective tissue, and an increased localization in the lung of bacteria that were cleared from the circulation.
