[Effect of stimulating doses of ionizing radiation on the stability of the liver mitochondria of chick embryos and chicks].
Treatments at the rate of 3 rad of chick embryos and young birds have led to the stabilizing of the mitochondrial structures and to lowering the access of enzymes to their substrates. The free activity of malate dehydrogenase drops. Electron microscopic studies reveal that the number of mitochondria rises following irradiation with stimulating doses (3 rad). Mitochondrial cristae remain intact and the matrix presents higher electronic density.
