Effect of ethimizole on changes in brain metabolism caused by overstimulation

During overstimulation (electrical stimulation for 3 h) of rats considerable changes are observed in their brain metabolism. These changes are manifested as exhaustion of the noradrenalin reserves and disturbance of energy metabolism, leading to a fall in the creatine phosphate level. Preliminary (before electrical stimulation) administration of ethimizole prevented the noradrenalin and creatine phosphate deficiencies in the brain tissue of the overstimulated animals.
