The purpose of the research: the analysis of histology and histochemistry of the Brandes organ of Strigea strigis and Alaria alata. The trematode marites of Strigea striges and Alaria alata were the material. Fixation of the material was carried out in 10% neutral formalin. The treatment of the specimens was carried out using the conventional histological and histochemical methods: with hematoxylin-eosin according to the method of Van Gizon, Mallory, with Sudan black B, sulema-Bromphenol blue according to Bonhage, with periodic acid Schiff reaction by Mac-Manus, alcian blue according to Stedman and Mowry and with toluidine blue. Histochemical reactions were performed with appropriate controls. The studies have shown that the structure of the Brandes organ of Strigea strigis and Alaria alata differs by their constituents and morphology of glandular cells. The histochemical reactions are similar. The cells of the glandular complex show bromophenolophilia, toluudinophilia and fuchsinophilia in periodic acid Schiff reaction speaks about the glycoprotein nature of the secreted substances. Bromphenophilia and sudanophilia of glandular cells cytoplasm indicate the presence of lipoprotein substances in them. The Brandes of S. strigis and A. alata is a morphofunctional unit, to which the principle of multi-functionality is inherent. It performs the main function – digestion of food components by means of developed glandular structures and specialized secretory activity. Its ability to fix the helminth tightly in the endostatin can be considered a secondary function of the organ.
