[Animal experiment studies on the effect of vitamin A on cortisol-induced wound healing disorders]

In animal experiments on rats we could show that wound healing, inhibited by cortison can be normalized by vitamin A administration. The reason for this behaviour is assumed to be an antagonistic effect of cortison and vit. A via the inflammatory phase on the amount of newly formed collagen. The increase of the alpha 1 and alpha 2 globulin fraction and the decrease of the albumin fraction in the serum caused by vitamin A seems to indicate this fact as well as the pronounced leucocyte depression under cortisol treatment.
