[Clinical investigations and cytological examinations of the nose in subject exposed to cement dust].

Mucous membranes of the nose of 90 persons exposed to cement dust were investigated clinically and cytologically. We found atrophic changes in 37.8% persons and hypertrophic changes in 13.3%. In a halt of the investigated persons abnormality in epithelium forms in cytological examination was demonstrated. The connection of inflammatory changes and pathological forms of the epithelium has been documented. The correlation between presentation of cement deposits and inflammatory infiltrations and atrophic and hypertrophic changes was confirmed.
