Tryptophan metabolism and vitamin B6 nutritional status in patients with schistosomiasis mansoni and in infected mice
(Cambridge University Press, 1992-06)
Patients infected with Schistosoma mansoni showed an abnormal response to a test dose of tryptophan, with little increase in the urinary excretion of kynurenine, hydroxykynurenine, xanthurenic and kynurenic acids, N1-methyl ...
Schistosoma mansoni: Effects on tryptophan metabolism in mice
In mice, infection with 20–30 cercariae of Schistosoma mansoni resulted in a considerable reduction in the formation of 14CO2 from [14C]tryptophan. Infected animals excreted significantly lower amounts of kynurenine, ...
Tryptophan metabolism in vitamin B6-deficient mice
(Cambridge University Press, 1990-01)
Vitamin B6 deficiency was induced in mice by maintenance for 4 weeks on a vitamin B6-free diet. Tryptophan metabolism was assessed by determining the urinary excretion of tryptophan metabolites, the metabolism of [14C]tryptophan ...
