Reversibility of biochemical and cytological alterations in broncho-alveolar lavagate upon cessation of dust exposure.

ABSTRACT

The objectives of the present study were 1. To investigate the nature and time course of the biochemical and cytological changes following acute and subchronic exposure intervals. 2. To investigate the dependence of the response upon the pulmonary burden of the test material. Alveolar clearance measurements were performed in parallel and are presented in a separate poster (1).
