Abstract:

Oxidative stress occurs in the brain due to stroke, Parkinson's disease, Alzheimer's disease, amyotrophic lateral sclerosis, trauma, aging and other conditions. Analysis of the effects of oxidative stress can involve quantitation of brain GSH, GSSG, NADPH and NADP. Reliable and rapid assays have been developed for these compounds and will be presented in detail. The assays have been used to analyze the effects of brain oxidative stress. Thermodynamic calculations can be performed to find the observed electrochemical potentials of the GSSG / GSH and the NADP / NADPH couples during oxidative stress. The biochemical consequences of these thermodynamic changes in the cell will be discussed as well as the defense mechanisms available to the cell to recover from oxidative stress.
