my modification in the fiber size distribution. rhis was verified by comparing the fiber size łistribution of a smali amount of the bulk :rocidolite sample artificially introduced in the ung of a mouse with the native crocidolite (data lot shown). The L/D remained constant in the ntoxicated group whereas in the control group io fibers were found in the mice lobes.
At the end of the experiment we observed an ncrease in the total number of the viable cells ecovered in the bronchoaNeolar liquids: 18000 ± 24000 cells/ml for the treated mice vs. 3000 ± 28000 for the control mice (Table 2). A
