[Hormonal stimulation of the reparative process in the skin or fats with vitamin A deficiency].

The effect of thyroid hormone on the regeneration of skin of A-deficient rats was studied. It was established that the reparative process in such animals was considerably retarded due to disturbances of the intensity and the character of the reaction. Under these conditions the succession of main stages of the regenerative process was maintained but there occurred a number of important qualitative and quantitative morphological disorders which substantially changed the course of healing of skin wounds. An additional injection of the thyroid hormone against this background had a favourable effect upon the skin regeneration but failed to produce a typical stimulating effect, characteristic of the hormonal agent in normality.
