We used the Ussing chamber model to study heme iron absorption by rat duodenal mucosa. Heme iron was obtained by enzymic digestion of bovine haemoglobin and concentration of heme (HPH). Its uptake and mucosal transfer was compared to iron gluconate (Gluc), at 100 microM and 1 mM. At 100 microM iron uptake (Qtot), mucosal retention (Qm) and transfer across the mucosa (Qs) was similar for the two...

PURPOSE To determine the value of serum ferritin, mean cell volume, transferrin saturation, and free erythrocyte protoporphyrin in the diagnosis of iron-deficiency anemia in the elderly. PATIENTS AND METHODS We prospectively studied consecutive eligible and consenting anemic patients over the age of 65 years, who underwent blood tests and bone marrow aspiration. The study consisted of 259 inp...

Dark green leafy vegetables (DGLVs) are considered as important sources of iron and vitamin A. However, iron concentration may not indicate bioaccessibility. The objectives of this study were to compare the nutrient content and iron bioaccessibility of five sweet potato cultivars, including three orange-fleshed types, with other commonly consumed DGLVs in Ghana: cocoyam, corchorus, baobab, kena...

mucosa or of the nails. Four women had taken iron tablets for long periods, but not for the six months previous to this investigation. During this time they had not observed any change in the ozaena. The Table contains the results of the haematological investigations. All patients had haemoglobin, haematocrit, and red cell count within normal limits. Serum iron was normal in eight patients, and...

BACKGROUND Milled rice is the staple food among Filipinos and is mostly consumed three times a day. Rice as a source of iron could therefore have an important role in the existing 37% prevalence of iron-deficiency anemia in the country. Previous iron absorption studies in Filipinos from rice and rice-based meals were carried out on milled rice but no research was done on brown rice of the same ...

To elucidate effect of chemical reagents addition on growth of aquatic plants in restoration of aquatic ecosystem, Spirodela polyrrhiza (L.) Schleid was used to evaluate its physiological responses to excess iron (Fe(3+)) and copper (Cu(2+)) in the study. Results showed that accumulation of iron and copper both reached maximum at 100 mg L(-1) iron or copper after 24 h short-term stress, but exc...

Nano-fertilizers can increase value of products in agriculture. Iron plays many important and essential roles in plant growth and development as compared to other micronutrients. In the present study, effects of different levels of enriched nano chelated Iron fertilizer (25, 50, 100, and 200 mg l-1)  were investigated in comparison with the common Iron (FeSO4.7H2O) on in vitro proliferation of ...

Background: For iron therapy in hemodialysis patients, intravenous rather than oral administration is recommended. Methods: For hemodialysis patients with serum ferritin levels less than 200 ng/ml (less than 100 ng/ml: 67 patients, between 100 and 199 ng/ml: 20 patients) with no iron therapy for more than 3 months, iron was administered intravenously (40 mg of ferric oxide saccharate for ten ti...
