title: [Disorders of energy metabolism in the rat brain under extreme exposures: a new method for assessing the energy state of the brain].
abstract: We propose a new method to evaluate energy state of the brain based on vital assay for phosphate metabolites and intracellular pH in the brain. A proposed Z-index describes a set of correlations between phosphates involved in brain energy metabolism assayed in vivo by magnetic resonance spectroscopy on 31P nuclei. We tried to use Z-index as a quantitative test for disturbed energy metabolism. Potentialities of Z-index for evaluating rat brain energy state after extreme influences (gamma [correction of X-] irradiation and postoperative shock of the brain cortex) have been demonstrated.
