Xanthine Oxidase Activity in Regenerating Liver
The xanthine oxidase activity of mouse regenerating liver has been shown to be elevated during the period of rapid liver growth and proliferation. This increase is evident when the enzyme activity is expressed per unit wet tissue weight, per unit nitrogen, or per cell. The adrenal cortex probably plays only a minor role in implementing this phenomenon. Further augmentation of the xanthine oxida...
متن کاملDietary factors related to liver xanthine oxidase.
In a previous study (1) it was shown that dogs maintained on a purified diet developed a defect in acetaldehyde metabolism. Of the five known enzyme systems that could theoretically be involved in acetaldehyde metabolism in viva (aldolase, mutase, carboxylase, aldehyde ox&se, and xanthine oxidase), the xanthine and aldehyde oxidases seemed most likely to be dependent upon a dietary factor not a...
متن کاملInhibitory Effect of Ruta graveolens L. Extract on Guinea Pig Liver and Bovine Milk Xanthine Oxidase
Flavonoids could serve as potent inhibitors of xanthine oxidase (XO). In the present study, the effects of Ruta graveolens L. extract and its major isolated flavonoids, quercetin and rutin, on guinea pig liver XO have been investigated. The inhibitory effects of R. graveolens, quercetin and its glycoside form, rutin, were assayed spectrophotometrically. R. graveolens...
متن کاملSynthesis of xanthine oxidase by rat liver slices in vitro.
The influence of dietary protein on the activity of rat liver xanthine oxidase has been studied by several workers (l-5) and would point to a relationship between the availability of amino acids and the activity of liver xanthine oxidase (2). It has been demonstrated that the loss of liver xanthine oxidase activity in the rat greatly exceeds the loss of liver protein during acute inanition (l),...
متن کاملFactors affecting the induction of xanthine oxidase of mouse liver.
In 1948 Keith et al. (1) demonstrated that in chicks fed a folic aciddeficient diet liver xanthine oxidase activity was far higher than that observed in birds receiving adequate levels of folic acid. It was postulated (2, 3) that 6-formylpteridine, a potent inhibitor of xanthine oxidase in vitro, was biologically active in controlling the oxidation of xanthine and hypoxanthine in vivo, since 6-...
