  • Abstract
  • Look Inside

In the perfusion experiments of the cat brain in situ by the modification of Geiger's method, the brain functions were maintained on high levels by the addition of cytidine monophosphate (CMP) and uridine mono-phosphate (UMP) to the "simpified" blood which consisted of Ringer's solution, bovine red cells, hydro-dextran and glucose. The electroencephalography showed the longer-lasting desychronized patterns during the perfusion experiments performed under unanaesthetized and inmobilized conditions with Flaxedil. CMP and UMP had the effects of increasing the glucose uptake by the brain and decreasing the lactate output from the brain.

The administration of CMP and UMP was useful to the patients suffering from the residual symptoms of the carbon monoxide poisoning as well as the head injuries. Forty mg of CMP and the same amount of UMP with 20 per cent glucose solution were injected intravenously for two to three weeks. CMP and UMP relieved remarkably the impairments of volition and memory. These symptoms are to be thought of the expressions of metabolic disturbances of the brain. CMP and UMP were effective to the patients not susceptible to the other drugs, these were supposed to be the metabolic activators of the brain. Also, the higher effectiveness were expected by the combined use of CMP and UMP with the other metabolic activators.
