Abstract

Circulating histamine level and forced expiratory volume in one second (FEY1) were measured by conventional methods in 39 selected workers (24 exposed and 15 controls) employed in a local cotton mill. There were 12 workers with byssinosis, who complained of breathlessness and tightness in the chest, showed elevated histamine concentrations in blood and a diminished percentage of predicted FEY1 values. Non-byssinotic subjects who were exposed to cotton dust had lower blood histamine concentrations and a higher percentage of predicted FEY1 values. Both exposed groups exhibited enhanced histamine levels and a lower percentage of predicted FEV1 values than unexposed subjects. The circulating histamine concentrations were negatively correlated with FEV1 among exposed workers.
