The characteristics of aristolochic acid nephropathy (AAN) are interstitial fibrosis and atrophy of the proximal tubules, but with no change in glomeruli. To investigate the effects of AA on renal functions and the pharmacokinetics (PKs) of p-aminohippuric acid (PAH) and inulin, New Zealand white rabbits were used in this study. The plasma concentrations of PAH and inulin were determined by val...

In this experiment, three concentrations (0.3, 0.6, and 0.9% of diet, as-fed basis) of two fructans, oligofructose (OF) and inulin, were tested against a 0% supplemental fructan control. Seven ileal-cannulated adult female dogs were fed a meat-based, kibbled diet and assigned to treatments in a 7 x 7 Latin square design. Dietary supplementation of fructans had no effect on nutrient intakes or i...

Dendritic cells are professional antigen-presenting cells that are responsible for initiating of the immune response. However, there are no reports on how the polysaccharides in an oral biofilm affect the viability of dendritic cells. Inulin, a fructooligossacharide, is one component of oral biofilm fructan that is used as an energy source by oral bacteria. In this study, we found that murine b...

A method for estimating glomerular filtration rate (GFR) has been developed that is based on an analysis of the total area under the plasma radioactivity-time curve after a single intravenous injection of [125I]iothalamate. Glomerular filtration rates obtained by this method (method A) and those obtained with two widely used single-injection techniques, the slope-intercept method (method B), a...

The effects of inulin-supplemented diet on Cu, Mn, and Zn bioavailability in recently weaned piglets raised at an experimental and a commercial farm were studied. Piglets were weaned at 28 days of age, when all of them were fed a barley-wheat based starter diet supplemented with a usual vitamin-mineral premix for piglets. The reference diet group received additional 50 mg of zinc per kg diet, w...

Insulin-resistant subjects have a slow onset of insulin action, and the underlying mechanism has not been determined. To evaluate whether a delayed transcapillary transport is part of the peripheral insulin resistance, we followed the kinetics of infused insulin and inulin in plasma and muscle interstitial fluid in obese insulin-resistant patients and control subjects. A total of 10 lean and 10...

PURPOSE This trial was conducted to evaluate the effects of oligofructose-enriched inulin on some of cardiovascular disease risk factors in women with type 2 diabetes. METHODS 52 females (25<BMI<35 kg/m2) with type 2 diabetes were randomly assigned to two groups. Participants received 10g/d oligofructose-enriched inulin (n=27) or 10g/d placebo (n=25) for 8 weeks. Fasting blood samples were ta...

The paper by Jackson et al. (1999) in the present issue of the British Journal of Nutrition is devoted to the analysis of the effect of inulin on blood lipids in moderately hyperlipidaemic men and women. The hypolipidaemic effect of dietary inulin-type fructans has been suggested by many animal studies, in which either a hypotriacylglycerolaemic, or a hypocholesterolaemic effect was observed wh...

For some time now prebiotics have been proposed to improve health by stimulation of beneficial bacteria in the intestine of humans and animals. The current study is aiming to show effects of feeding of either 2% inulin or 2% lactulose in milk replacer on performance and intestinal morphology of male Holstein-Friesian calves. After 20 weeks of feeding inulin led to significantly higher daily wei...

As a soil fungus, Aspergillus niger can metabolize a wide variety of carbon sources, employing sets of enzymes able to degrade plant-derived polysaccharides. In this study the genome sequence of A. niger strain CBS 513.88 was surveyed, to analyse the gene/enzyme network involved in utilization of the plant storage polymer inulin, and of sucrose, the substrate for inulin synthesis in plants. In ...
