[Lactic acid in the human umbilical cord. Influence of glycolysis in the blood in cord and in cordonal tissue (author's transl)].
The blood staid in human umbilical cord increases his lactate concentration (about + 4 mg/l/mn, in average). It is the fact of an high metabolic activity of foetal erythrocytes for glycolysis, but also of action of cordonal tissue itself. This tissue, after elimination of blood, allows an high concentration of lactate, which increases when cord is kept at room temperature, reaching and rising above 1 or 2 g/kg, after many hours. This glycolytic process indicates than cord tissue has a metabolic activity which seems to be in relation with the high lactate concentration of the amniotic fluid.
