[An evaluation of endogenous lectins in the intrapulmonary metastases of osteogenic sarcoma]

Assessment is made of the presence or absence of specific sugar receptors (lectins) in patients operated for intrapulmonary metastases of osteogenic sarcoma. Investigations were carried out on histochemically stained paraffin sections for the separate types of sugars. Highest was the presence of specific receptors for sialic acid and for N-acetylglucosamine, followed by those for ramnose and heparin and least for mannose and maltose. Lectin determination is a new branch in morphological science, assisting clinical practice, special surgical activity by the attempt for quantitative grading of cell populations in norm and in their neoplastic development.
