Abstract
The determination of total thiamin, free thiamin, thiamin di phosphate (TDP) plus thiamin triphosphate (TTP), and total α- hydroxyethylthiamin (HET) levels in rat brain in control, deficient, oxythiamin- (OTH) and pyrithiamin- (PTH) treated rats was accomplished. It was found that the TDP + TTP/thiamin ratio observed in the thiamin-deficient, OTH- and PTH-treated rats was constant and did not differ from the ratio observed in the control rat brains. The brain levels of TDP + TTP decreased to 39% and 12% of the control thiamin levels in deficient and PTH-treated rats respectively. The brain HET and TDP + TTP levels of the OTH-treated rats were not significantly different from the controls. The HET levels in the PTH rats decreased significantly ( α = 0.005) by treatment day 4 and decreased to one-seventh of the control values in the terminal stages. A significant drop in the HET levels from the control levels was interpreted to mean that the pyruvate utilization was significantly impaired in the brain.
