[Effect of extracts from loach eggs and embryos exposed to insulin on glucose-6-phosphate dehydrogenase activity].

It is established that the incubation of glucose-6-phosphate dehydrogenase solution (33 micrograms of enzymic protein per 1 ml) with extracts of unfertilized loach eggs and embryos results in a marked stabilization of the enzyme with respect to its inactivation. Extracts from the embryos preliminary affected by insulin possessed a lower stabilizing ability, the hormonal effect being removed to a considerable extent by actinomycin D and cycloheximide.
