Abstract
Asymptomatic cotton workers as well as those with byssinosis showed a significant decrease in forced expiratory volume during exposure to cotton dust. The patterns of the forced expiratory volume response over a week suggest that there are distinct individual patterns of response not dependent upon previous cotton dust exposure. Forced expiratory volume was found to discriminate better between exposure to cotton dust and control than other measures of the spirogram. Oxygen tension in arterial blood decreased during exposure; occasionally these decreases were large. Peripheral blood polymorphonuclear leukocyte counts and the polymorphonuclear leukocyte to epithelial cell ratio from nasal smears increased during cotton dust exposure. These changes appear to be important in the response to cotton dust and warrant further study.
