In a 5-week study, 120 crossbred weaning pigs (age 4 weeks) were used to examine the effects of an additional Fe-injection and immunization moment on the growth and humoral immune response. Pigs were allotted to one of eight treatments based on body weight and litter origin. Factors included: (1) single intramuscular injection (day 3 after birth) vs. double intramuscular injection (days 3 and 2...

Second-parity sows (n = 7) were fed diets containing organic or inorganic trace minerals, and their progeny (n = 68) were used to determine the Fe status of pigs at birth and nursing and postweaning phases. The experiment comprised 2 parts, in which the first experiment was a 2 x 2 factorial arrangement. Sow trace mineral (organic vs. inorganic) was the first factor evaluated, and the injection...

A previous study has shown that a single injection of ferric nitrilotriacetate (Fe-NTA) produces hepatic parenchymal iron loading in rats. The present paper reports on iron uptake by rat liver and iron toxicity in the liver after a single injection of Fe-NTA (7.5 mg Fe/kg B.W.). Iron uptake was examined with 59Fe-NTA and Fe-[14C]-NTA. Thirty percent of the injected 59Fe was incorporated in the ...

The determination of total iron in pharmaceutical products and natural waters as Fe(II) using a sequential injection system was investigated. A cadmium reductor consisting of cadmium granules was used to reduce Fe (III) to Fe (II). The Fe (II) was then determined (by its reaction with 1,10 Phenanthroline ) as a [Fe(phen)3 ] complex at 515 nm with a UV/Vis spectrophotometer. The linear range of ...

introduction: acute renal failure is a common consequence of sepisis due to concurrent renal ischaemia. the role of nitric oxide (no) in endotoxaemia and in ischaemic injury in the kidney is not well defined. material and methods: in this study we have used an animal model of sepsis induced by injection of bacterial lipopolysaccharide (lps) in the rat and measured renal nitric oxide by x-band e...

We consider the spin injection from Fe into ZnSe and GaAs in the ballistic limit. By means of the ab initio screened Korringa-Kohn-Rostoker method we calculate the ground-state properties of epitaxial FeuZnSe(001) and FeuGaAs(001) heterostructures. Three injection processes are considered: injection of hot electrons and injection of ‘‘thermal’’ electrons with and without an interface barrier. T...

Large doses of ascorbic acid may mobilise Fe from Fe-binding proteins in vivo which in turn could catalyse lipid peroxidation, a process associated with degenerative diseases. This hypothesis was tested in vitro in the serum of Fe-loaded animals. Eighteen male guinea pigs weighing about 500 g on arrival were allocated to two groups of nine. Fe loading was induced in one group by two intraperito...

Two analytical methods, which prove the utility of a potentiometric flow injection technique for determining various redox species, based on the use of some redox potential buffers, are reviewed. The first is a potentiometric flow injection method in which a redox couple such as Fe(III)-Fe(II), Fe(CN)(6) (3-)-Fe(CN)(CN)(6) (4-), and bromide-bromine and a redox electrode or a combined platinum-b...
