title: [Intra-encephalic injections of actinomycin D in the chick embryo. Autoradiographic study].
abstract: 42 hour-old chick embryos receive intraencephalic injections of a radioactive Actinomycin D solution. The autoradiographic study of the embryonic head after treatment shows that the injected solution remains in the encephalon. In order to avoid some diffusion of the solution in the surrounding territories, it is necessary to take care of the encephalic inner pressure. These experiments allow to a better approach of studying the influence of Actinomycin D upon the embryonic head morphogenesis.
