Excretion of Sulfur During Healing of Experimental Wounds.

The effect of wounding on metabolism of the sulfur amino acids was studied by following the excretion of sulfur in normal and wounded rats. After wounding, there is a relative retention of sulfur, even though a greater amount of nitrogen than normal is excreted. Studies with S35 labeled cystine and methionine indicated that the metabolism of these amino acids is greater in wounded than in normal animals.
