[Interrelationship between the thiamine content, thiamine diphosphate-dependent enzyme activity and reduced glutathione level in the rat liver].

Changes in the amount of thiamine, reduced glutathione, thiamine diphosphate-dependent dehydrogenase activity has been traced after thiamine injection to thiamine-deficient rats and oxythiamine to normal rats. The obtained data show that a drop in reduced glutathione level was a primary reason of the alpha-keto-acid dehydrogenase activity reduction under conditions of the thiamine deficiency. The existence of immediate connection between thiamine and glutathione metabolism is supposed.
