The relationship of phosphate and lipids to xanthine dehydrogenase
Experientia, 1968La xanthine deshydrogenase, enzyme du foie de rat, a ete obtenue par 2 procedes differents: (a) avec et (b) sans traitement par le Butanol. La teneur totale en phosphore des 2 preparations a ete etonnament elevee. Soixante %, a peu pres, du phosphore total s'est montre soluble dans des solvents de lipides.

Liver xanthine dehydrogenase and iron mobilization
Biochemical and Biophysical Research Communications, 1982Abstract Administration of a tungsten-supplemented diet to young rats for 10 weeks resulted in an 80% – 90% reduction in the liver xanthine dehydrogenase activity and a 100% increase in the liver non-heme iron content as compared to control animals. A time course study of the effect of dietary tungsten in adult rats demonstrated that an increase in ...

Regulation of the Kidney Xanthine Dehydrogenase by Glutaminase
Archives Internationales de Physiologie et de Biochimie, 1979The steady-state concentrations of glutamine, glutamate and ammonia in the kidney cells might regulate the rate of renal xanthine dehydrogenase activity. Both glutamate and glutamine were found to be effective inhibitors of the renal xanthine dehydrogenase activity in vivo. The inhibition by glutamate depends essentially on the glutaminase inhibition.

Xanthine dehydrogenase in bovine blood serum
Experientia, 1956Le serum sanguin des bovides contient des quantites elevees de xanthine dehydrogenase. On l'a demontre par le dosage de l'acide urique et la reduction du triphenyltetrazolium apres incubation avec de la xanthine. Des experiences complementaires faites avec differents inhibiteurs de la xanthine oxidase et la preparation d'une fraction active donnant le ...

Control of xanthine dehydrogenase in the chick pancreas
Developmental Biology, 1967Abstract Fisher et al. (1967) have shown that pancreatic xanthine dehydrogenase in newly hatched chicks is induced by feeding whereas this enzyme in the liver, kidney, and duodenum is unaffected by the ingestion of food. This induction is due to some substance(s) in the feed and not to the nutritional balance of the diet.

Comparison of the kinetic behaviour of xanthine oxidase and xanthine dehydrogenase
Journal of Molecular Catalysis, 1981Abstract In the oxidation of hypoxanthine and xanthine by chicken liver xanthine dehydrogenase and bovine liver and milk xanthine oxidase, activation appears at high substrate concentrations. Hypoxanthine concentrations greater than 0.04 mM inhibit the bovine enzyme; concentrations greater than 0.09 mM inhibit the milk enzyme. On the other hand, uric

Excitotoxic increase of xanthine dehydrogenase and xanthine oxidase in the rat olfactory cortex
Developmental Brain Research, 1995Excitotoxic lesions induced by systemic injection of kainic acid, resulted in 2-3-fold increase of xanthine dehydrogenase and xanthine oxidase activities in the rat olfactory cortex 48-72 h after drug administration. A significant increase of the xanthine oxidase/dehydrogenase ratio was also observed at 4 and 48 h post-injection.

Xanthine (2,6-dioxypurine), which occurs in certain legumes and other plants, was fed in artificial diet to larvae of two noctuid moth species, a legume specialist,Anticarsia gemmatalis, and a generalist,Spodoptera frugiperda. In addition, diets either lacked or contained allopurinol (4-hydroxypyrazolo(3,4-d)-pyrimidine), an inhibitor of xanthine ...
