[Succinate dehydrogenase activity in the mesonephros in the process of development of chick embryos]

The activity of succinate dehydrogenase in the mesonephros tissue of chick embryos is rather high on the 6th day of embryonal development and is not subjected to significant changes up to the 17th day. The absence of wide variations in the activity of this enzyme during the period of degeneration of the mesonephros may be due to a parallel decrease in the organ's mass and in the number of its mitochondria.
