Antianemic medicament ferrous gluconate, ferrous fumarate, and a Dynabi tablet with a basic iron bearing ingredient were studied with the use of Mössbauer spectroscopy. Room temperature spectra of ferrous gluconate gave clear evidence that the two phases of iron were present: ferrous (Fe2+) as a major one with a contribution at and above 91 a.u.% and ferric (Fe3+) whose contribution was found t...

background: ferrous sulfate is the most used supplement for treating anemia, but it can result in unfavorable side effects. nowadays, nanotechnology is used as a way to increase bioavailability and decrease the side effects of drugs and nutrients. this study investigates the effects of nanoparticles containing iron on blood and inflammatory markers in comparison to ferrous sulfate in anemic rat...

The Oxford Whole Body Counter was used to measure absorption from various therapeutic preparations of iron in five groups of subjects. Succinic acid enhanced absorption of iron when added to a solution of ferrous fumarate, but not when given with tablets of ferrous fumarate or ferrous sulphate. Ferrous fumarate plus ascorbic acid was absorbed better than ferrous fumarate alone but no better tha...

The oxidation of ferrous iron and elemental sulfur by Thiobacillus ferrooxidans that was absorbed and unabsorbed onto the surface of sulfur prills was studied. Unadsorbed sulfur-grown cells oxidized ferrous iron at a rate that was 3 to 7 times slower than that of ferrous iron-grown cells, but sulfur-grown cells were able to reach the oxidation rate of the ferrous iron-adapted cells after only 1...

BACKGROUND There is a need to determine whether iron absorption from iron amino acid chelates is protected from inhibition by dietary phytate and regulated normally by iron status. OBJECTIVE The objective of this study was to compare iron absorption from ferrous sulfate, ferrous bisglycinate, and ferric trisglycinate in whole-maize meal; to determine whether iron from ferrous bisglycinate and...

Anoxic iron-rich sediment samples that had been stored in the light showed development of brown, rusty patches. Subcultures in defined mineral media with ferrous iron (10 mmol/liter, mostly precipitated as FeCO3) yielded enrichments of anoxygenic phototrophic bacteria which used ferrous iron as the sole electron donor for photosynthesis. Two different types of purple bacteria, represented by st...

Pretreatment with low-dose thrombin attenuates brain edema induced by iron or intracerebral hemorrhage (ICH). Ceruloplasmin is involved in iron metabolism by oxidizing ferrous iron to ferric iron. The present study examines whether thrombin modulates brain ceruloplasmin levels and whether exogenous ceruloplasmin reduces brain edema induced by ferrous iron in vivo. In the first set of experiment...

UNLABELLED Iron has been suggested to reduce the erosive potential of cola drinks in vitro. OBJECTIVE The aim of this study was to evaluate in situ the effect of ferrous sulfate supplementation on the inhibition of the erosion caused by a cola drink. MATERIAL AND METHODS Ten adult volunteers participated in a crossover protocol conducted in two phases of 5 days, separated by a washout perio...

conclusions it can be concluded that gi complications in pregnant women using ferrous sulfate are mostly caused by physiologic changes of pregnancy rather than ferrous sulfate; therefore, it is not reasonable to stop using ferrous sulfate due to gi complications. results none of the gi complications were significantly different between the ferrous sulfate and placebo groups at 24th - 28th and 3...

R ECENTLY a new reagent was proposed for the determination of cholesterol (1, 2). This reagent was purported to be saturated ferrous sulfate in glacial acetic acid. Since it has been reported that ferrous sulfate is qualitatively insoluble in anhydrous acetic acid (3, 4) and that ferrous iron is “subject to pronounced air oxidation in glacial acetic acid” (5), it was felt that several factors s...
