The aim of the investigation is to study the sexual peculiarities of lymphoid formations in trachea and bronchi of individuals of different age groups. The lymphoid apparatus of trachea and bronchi has been studied. taken from 58 humans of different age and both sexes, died or perished in accidents without pathologies of respiratory and immune systems was studied via microscopical methods. The trachea and bronchi principalis were fixated in 10% solution of formalin and in water Karnua. The longitudinal and transverse pieces were taken from cartilaginous and membranaceus walls of the upper, middle and lower one-third of the trachea and each bronchi principalis. These cuts 5-7 urn in thickness were stained with hematoxylin-eosin, azure-2-eosin, with hematoxylin-picrofucsin by Van-Gizon technique, with methyl green-pironin by Brashe technique (after fixation in water Karnua) and reaction by Grymelius. The results of the research showed that during postnatal ontogenesis the sex related differences are observed in cell composition of the trachea and bronchi princiapalis' lymphoid structures. In adolescent, juvenile and 1-st mature period in females the percentage of small and big lymphocytes, cells with mitosis, plasma cells is more, but the percentage of medium lymphocytes and cells with degeneration is less than in males
