[Gallium sulfate and skin allografts in the mouse]

Survival of skin allografts in mice are prolonged when these animals are injected subcutaneously with gallium sulfate before and after the grafting. The average survival is then 17, 2 days whereas it is 12,5 days for controls. For mice treated with an immunodepressive drug such as cortisone acetate average survival is 13,4 days; it is 17 days when cortisone has been added to the metallic salt.
