Abstract
Drăgan's high-speed PBT (polychrome blue tannin) staining method enables cellular elements to be detected in oral smears in one minute at most. The basic dyes in the polychrome blue solution allow the acid-group-containing substrate to be detected in the nucleus, in the cytoplasm of epithelial cells and leukocytes, as well as in the elements of the flora. The chromatin shows a distinct basophilic, orthochromatic reaction. The fine, reddish-violet metachromatic granules in the cytoplasm are of a glycolipid nature and occur with the tonofibrils. The keratohyalin granules show a basophilic orthochromatic or metachromatic, homogeneous or granular reaction in relation to the chemically acid portions of their structure.
