[Radiation-induced changes in protein synthesis in the liver of chicks at different stages of postnatal development].

Dynamics of changes in synthesis of cytoplasmatic and mitochondrial proteins in liver of chickens of various age exposed to low dose (0.05 Gy) ionizing radiation has been studied. It has been shown that low dose intensified the incorporation of labeled amino acids into the proteins in all the stages studied, although the degree and character of protein synthesis activation in cytoplasma and mitochondria are different.

[Effect of small doses of gamma radiation on the activity of marker enzymes in the plasma membranes of chick embryo liver].

A study was made of marker enzyme activity in plasma membranes of chick liver during embryogenesis in normal conditions and after exposure to ionizing radiation. It was shown that irradiation with small doses of eggs prior to incubation and of chick embryos during different periods of the prenatal ontogenesis caused essential changes in activity of membrane-bound enzymes of liver plasmolemma. Stimulation with small radiation doses was most effective with preincubation irradiation of eggs and most manifest at later stages of the prenatal ontogenesis.
