Elastin Content of the Human Lung.

Abstract

Summary1. An alkaline digestion method for quantitative determination of elastin has been adapted for study of lung parenchyma. 2. Concentration of elastin in the adult human lung has been determined over a wide age span, and has been found to increase with age. 3. Concentration of elastin in lung parenchyma subjacent to areas of bulla formation is significantly reduced.
