Iron (Fe) deficiency is a major human health concern in areas of the world in which diets are often Fe deficient. In the current study, we aimed to identify appropriate methods and optimal dosage for Fe fortification of lentil (Lens culinaris Medik.) dal with FeSO₄·7H₂O (ferrous sulphate hepta-hydrate), NaFeEDTA (ethylenediaminetetraacetic acid iron (III) sodium salt) and FeSO₄·H₂O (ferrous sul...

BACKGROUND Though pregnant women in Ghana routinely receive iron and folic acid supplements, the prevalence of anaemia continues to be as high as 70%. OBJECTIVE To determine the impact of zinc deficiency on iron status indicators in pregnant women. DESIGN A double-blind, randomized controlled trial (RCT) of joint iron and zinc supplementation. SETTING The study was conducted in the Upper ...

An attempt was made to purify Clostridium perfringens Beta toxin. Crude toxin prepared by ammonium sulphate precipitation of culture supernatants was purified by chromatography on Sephadex G50, Sephadex G100 and DEAE cellulose. This material, although highly purified was not homogeneous on polyacrylamide gel electrophoresis. It had a toxicity of 800 000 mouse MLDs/mg N, a typical protein absorp...

The aim of this study was to find optimum dose of ferrous sulphate and hydrogen peroxide in Fenton oxidation process for treatment of dyeing wastewater. Fenton process is the advanced oxidation method used mainly for COD and colour removal. Experiments are done on synthetic wastewater prepared from three different dyes; acidic, disperse and reactive; and also effluent obtained from industry. Th...

1. The effect of fortification of food with iron to provide 10 mg elemental Fe/child per d was studied in preschool children maintained on a cereal diet, over a 5-month period. 2. The absorption of 5 mg Fe as ferrous sulphate mixed in one meal was 3.3% of the test dose and when 3.3 mg was given with each of three meals over a 2 d period the corresponding value was 4.8%. 3. The mean absorption o...

OBJECTIVE To determine the degree of liking of the Oportunidades programme dietary supplements (DS)--purees and beverages--added with different iron salts (IS): reduced iron (RI), ferrous sulphate (FS) or ferrous fumarate (FF) during 24 weeks of storage. MATERIALS AND METHODS The DS were evaluated through a hedonic scale for aroma, flavour and colour attributes; at time zero and every eight w...

Szucs (1913) reported that hydrogen peroxide increased the permeability of the living cell. Following up a previous observation [Bokorny, 1886], he found that if threads of Spirogyra were treated first with hydrogen peroxide and then with ferrous sulphate solutions, a dark precipitate appeared within the cells. He concluded that the hydrogen peroxide had so increased the permeability of the cel...
