[Studies on the distribution of glycogen phosphorylase and succinate dehydrogenase in the humeral epiphysis of various-age rats].
In the chondrocytes of the humerus epiphysis of newborn and 8-, 30- and 60-day-old albino rats, glycogen phosphorylase and succinate dehydrogenase activity was found. The enzymatic pattern of glycogen phosphorylase and succinate dehydrogenase diverges significantly within the age groups. In the chondrocytes of cartilage epiphysis of newborn and 8-day-old animals glycogen phosphorylase is distinctly present. The enzyme is reduced in 30- and 60-day-old rats. The initial moderate reactions of succinate dehydrogenase in the column cartilage and in the proximal hypertrophic cells demonstrate an additional activity from 30-day-old animals. The osteoblasts of the metaphysis demonstrated a strong reaction.
