title: [Redox-state of NAD pairs and activity of lactatedehydrogenase and NADase in guinea pig tissues at different stages of development of experimental allergic encephalomyelitis].
abstract: Changes of NAD content, redox-state, enzyme activity in the brain and liver tissues of Guinea pigs at different stages of development of experimental allergic encephalomyelitis (EAE) were investigated using the model of multiple sclerosis. It was shown, that the most legible changes of the investigated parameters occur on the preclinical stage and the stage of initial neurological symptoms. The increase of the brain NAD level and reduction properties of NAD+/NADH pairs reduction properties against a background of inhibition of lactatedehydrogenase activity was observed in the early terms of EAE development (7-15 day). The liver lactatedehydrogenase activity is increased at an initial stage. NAD-ase activity is increased in the medium term (18-21 day) that correlates with changes of this enzyme activity in the blood serum. In the term of strongly expressed neurological signs (26-33 day) the sharp drop of NAD content in the brain and liver is observed. The role of the obtained results at different stages of EAE development is discussed.
