[Distribution and activity of certain dehydrogenases in the erythropoietic process in pigeons].
Cytochemical methods were applied for detecting of distribution and dynamics of dehydrogenase activity (H- and M-subunits of lactate dehydrogenase, malate and succinate dehydrogenase) during maturation of pigeon erythrocytes. In the erythroblasts the above enzymes were seen in the whole cell; in reticulocytes - only around the nucleus; in erythrocytes - on the border line between the nucleus and the cytoplasm. The cytophotometric data show a decrease in enzymatic activity during maturation being more significant in the period from the erythroblast to reticulocyte development than from the reticulocyte to erythrocyte development.
