Histochemical studies allowed to investigate the main aspects of the chemical statics and dynamics of the pituitary gland: location and nature of the reaction to the contents of nucleic acids, proteins, and lipids in cattle of different ages.It is installed the increased intensity of histochemical reactions to identify DNA and RNA. This indicates about the nucleic nature of the colloid, which is produced by the body and is a carrier of hormonal substances. The greatest concentration of nucleic acids was observed in the adenohypophysis of animals of 6 months of age. Here they are accumulated more in the adenocytes nuclei. The cells of a connective–tissue capsule of the pituitary gland have increased intensity of histochemical reactions to identify nucleic acids. Common proteins found in all histoststructure of the pituitary gland, but sometimes the preferential localization of the total protein in the pituitary gland of cattle in the age aspect is the anterior pituitary. The lipid in microstructures of the pituitary gland contained in all its parts. The intermediate fraction and the capsule of the pituitary gland are rich by them. Fat cells in the structures of the pituitary gland have not been identified because they usually are contained in the form of biocomplexity connections.The nature of the histochemical features of the pituitary gland of cattle depends on the age of the animals, and we studied the histochemical reactions of the colloid allow to characterize it as a mucopolysaccharide with impurities of proteins and a small amount of lipids.
