Healing of a standardized bone injury in guinea pigs has been studied following treatment with zinc compounds. Zinc uptake, isotopic zinc uptake, histology of the regenerative area and growth response of the animals were used as parameters of response. Zinc chelates able to form bidentate structures carrying an anionic charge were more effective than zinc sulfate and untreated controls in speeding early healing. Ultracentrifugal studies have established the formation of a ternary complex in plasma between albumin zinc and effective wound healing ligands. Histidine but not other amino acids is capable of the same molecular combination. The data provide a reasonable molecular basis for explanation of the in vivo results.
