Local absorption of zinc from wounds treated with various zinc-compounds.

It is shown that in the rat, zinc is absorbed from excisional wounds into serum, from various locally applied zinc oxide preparations as well as from zinc peroxide and zinc sulphate. The most pronounced absorption of zinc to serum was recorded from wounds treated with zinc peroxide. Microscopically the cellular inflammatory response observed in wounds treated with a gauze sponge impregnated with a zinc sulphate solution was weaker than that found with the other treatment methods used.
