متن کاملStudies on Thiamine Analocues
Several analogues of thiamine’ are known to compete with the vitamin when administered to animals. Thus, Woolley and White (1) have observed that pyrithiamine caused the manifestation of typical thiamine deficiency symptoms, which could be competitively overcome by the vitamin. The antivitamin effect of oxythiamine in mice has been reported by Soodak and Cerecedo (2). Cerecedo et al. (3, 4), co...
متن کاملHistochemical study on thiamine.
The authors have applied the thiochrome method for determining thiamine to histochemical investigations and could observe the localization of thiamine in cells and tissues (1-6). Independently of our study, v. Muralt (7) had already reported a investigation on histological pictures of thiamine in peri pheral nerves by the thiochrome method, which was however unavailable to the authors at that t...
متن کاملAction of the thiamine antagonist bacimethrin on thiamine biosynthesis.
Bacimethrin is an analog of the 4-amino-5-hydroxymethyl-2-methylpyrimidine (HMP) moiety of thiamine and inhibits the growth of Salmonella enterica serovar Typhimurium on a defined medium. Two classes of mutants that had increased bacimethrin resistance were isolated and characterized. Results showed that overexpression of the thi operon or specific lesions in thiD resulted in a bacimethrin-resi...
متن کاملEffects of thiamine deficiency and thiamine administration on the thiamine diphosphate-dependent enzymes in rat liver.
The activities of pyruvate and 2-oxoglutarate dehydrogenases were determined by a spectrophotometric method according to Massey, that of transketolase deter mined by Racker's method. The values of enzyme activity as well as the thiamine contents in the preparations were compared with those of the animals whose deficiencies were restored by thiamine administration. The thiamine deprivation resul...
