Incorporation of Sulfur Amino Acids by Leucocytes during Wound Healing

[摘要] The effect of wounding on the uptake of S35-labeled amino acids by leucocytes of the blood was studied. Although a significant increase in the rate of uptake of cystine was observed after wounding, there appeared to be no effect on the incorporation of methionine. The effect was most pronounced on the third day after wounding; by the seventh day, the uptake of cystine had returned almost to the normal control rate. Experiments with substances which inhibit metabolism indicated that different mechanisms are involved in the uptake of methionine and of cystine by leucocytes.
