Levels of liver glycogen during normal and radiation-induced metamorphosis in Rana cyanophlyctis.

This study shows that significant changes in the pattern of glycogen deposition are brought about by irradiation with 2,000 R gamma-rays. The sharp fall during the 1st week can be attributed to its emergent mobilization. However, glycogen stored in the liver during the 2nd and 3rd week prior to the resorptive process substantiates the fact that tadpoles complete metamorphic transformations in spite of sublethal irradiation.
