Utilization of Sulfur Amino Acids During Healing of Experimental Wounds.

Abstract
Wounded rats injected with L-methionine-S35, accumulate the radio-sulfur in the wound tissue, even when the S35 content of the other tissues is decreasing. The largest part of the S35 in the wound tissue appears as cystine-S35. The rate of deposition of cystine in the regenerating wound tissue is greater than that of methionine. The rate of healing (as measured by the healing index) is a function of the cystine content of the wound tissue.
