[Pyruvate dehydrogenase activation in the skeletal muscles of the chick embryo during electrostimulation]

The pyruvate dehydrogenase activity in the skeletal muscle during chicken embryo-genesis and early postnatal life amounts to 550 +/- 50 mU per g tissue, on the average; electrostimulation (1 Hz) induced a two-fold increase in its activity starting from the 15th day of incubation.
