Abstract
The rats were inhaling amosite and wollastonite fibres at two concentrations (30 and 60 mg/m3) one hour every second day and cigarette smoke of 3 cigarettes per day (with the exception of Saturdays and Sundays). They were sacrificed after 6 month of exposure. Bronchoalveolar lavage (BAL) was performed and selected inflammatory and cytotoxic parameters were examined. Amosite: inflammatory parameters were the most changed after 60 mg/m3 in both groups with or without smoking; the cytotoxic parameters were strongly influenced by smoking. Wollastonite (asbestos substitute) inhalation confirmed lower inflammatory and cytotoxic effects on all examined animal groups in comparison with amosite.
