[Lower leg ulcers and 2,3-diphosphoglycerate blood level].

In a study on 30 patients suffering from arterio-venous leg ulcers, we found an increased blood level of 2,3biphosphoglycerate (10.33 mumol/ml; control group: 5.16 mumol/ml). This difference, which is statistically significant (p less than 0.001), shows that the blood oxygen pressure is lower both in the tissue of the leg ulcer (literary communication) and in the whole body.
