Abstract

The paper contains results of the investigation of the laser-induced fluorescence detection method for the assessment of brain metabolism in situ through the dura mater. Models of anoxia and acute brain ischemia were used for the evaluation of reliability of the method utilizing registration of reduced tissue pyridine nucleotides fluorescence, as well as for the assessment of the viability index, based on the conversion of oxy- and deoxyhemoglobin. Some pathobiochemical mechanisms of alterations in the pool of pyridine nucleotides in anoxia and ischemia were analyzed.
