title: Effect of calcitonin on phosphorylase a and glucose-6-phosphatase activities in the hepatic particulate glycogen of rats.
abstract: A single dose of calcitonin (CT) (70 mU MRC/100 g body weight) was administered in 50 and 90 days old male Wistar rats. In both ages CT determined a rise of Phosphorylase a and glucose-6-phosphatase activity as well as an increased calcium accumulation at the level of liver particulate glycogen. In the rats receiving CT glycemia increased and the liver glycogen content decreased. With the exception of liver glycogen the other metabolic parameters studied were modified at the two ages in the same manner under the influence of the same dose of CT.
