title: [Features of the histotopography of proteins in human chorionic and placental tissues at different stages of normal and pathologic development].
abstract: Contents of total, basic and acidic proteins have been studied in the human chorionic tunic at successive stages of a normal embryogenesis and at certain types of pathological pregnancy by means of histochemical methods. According to the staining degree, there is certain heterogeneity of the villi at various differentiation levels. An essential decrease in intensity of histochemical reactions is revealed in the chorionic villi at stillbirth and tetania gravidatum. The peculiarities in histotopography of the proteins and aminoacids studied reflect principle histochemical and structural reconstructions of the chorionic villi at various stages of normal and pathological pregnancy.
