[Metabolism of vitamin B1 and its di- and triphosphate esters in experimental allergic encephalomyelitis].
Biological significance of thiamin in development of experimental allergic encephalomyelitis has been elucidated. It has been shown that at the late preclinical stage of the disease thiamine metabolism is predominantly directed towards the maintaining of cellular metabolic homeostasis, whereas at the stage of clinical symptoms the anabolic process gives way to catabolic decomposition. Among tested thiamine phosphates the triphosphate ester is the most informative parameter in demyelinizing processes. Thiamine injections to immunized animals accelerate the vitamin phosphorylation depleting the reducing and energy potentials of the cell. Such thiamine antagonist as oxythiamine inhibits phosphatase reactions.
