[Assay of erythrocyte ATP by chemoluminescence. Protective action induced by pentoxifylline on the depletion of energy from stored erythrocytes].

A new method to measure erythrocyte ATP levels is used. The authors have incubated 6 whole blood samples and 7 samples containing washed red blood cells for 6 h. They measured ATP levels and confirmed an important decrease of the values during the time. If the same samples were incubated with pentoxifylline (1.4 X 10(-4) M), the ATP decrease was less relevant.
