Effect of Intratracheally Administered Wulfenite on Lungs of Mice

Abstract

Summary

The piezoelectrically active dust, wulfenite, of maximum particle size .074 mm was administered intratracheally to 38 mice. In no instance was there evidence of cellular reaction to the wulfenite in the lungs of these animals. The theory that a substance, by virtue of its possession of piezoelectric properties, can produce reaction in the living organism requires further confirmation.
