[Modification of the level of adenosine triphosphate in digital pulp capillary blood in patients with microcirculatory disorders following i.v. injection of coenzyme A (CoA 1000)]. / Modification du taux d'adénosine tri-phosphate (ATP) dans le sang capillaire prélevé au niveau de la pulpe digitale, dans les troubles de la microcirculation, après injection i.v. de coenzyme A (CoA 1000).

Capillary blood ATP assay was performed in 2 groups of patients (diabetic and non-diabetic) with disorders of microcirculation, before and several minutes after 2 mg I.V. of Coenzyme A (CoA 1000). Values obtained showed a significant increase in both groups. The hypothesis advanced, based on previous experimental data indicating an action of CoA on intracellular calcium movement, is that CoA 1000 acts by elevation of the membrane ATP/Ca+ ratio of red corpuscles, and possible activation of their deformability and flow rate in the microcirculation.
