Treatment of Anemia Progression via Magnetite and Folate Nanoparticles In Vivo. (4th March 2014) - Elsayed, Hanaa Hussein
Abstract : Iron deficiency anemia is a major global public health problem. Food fortification with iron (Fe) can be an effective strategy to control iron deficiency. An iron oxide nanoparticle (NP) is a new physical and chemical property form. These properties (small particle size, unique physical properties) make nanoiron a great scientific interest especially in the treatment of anemia. The study aimed to reduce anemia by nanoparticles (NPs). Forty-eight adult female Sprague-Dewily rats were divided into four groups (12 rats each). Group A represented a negative control. Other groups were fed standard diet iron free and three time of require zinc to reach anemic. Group B fed standard diet with ferrous sulfate until the improvement of the situation of anemia or for 8 weeks. Groups C and D were divided into three subgroups; each subgroup was fed a dose from magnetite or folate coated magnetite NPs. Results showed that symptoms of loss of appetite and severe lethargy demonstrate that magnetite and folate-coated magnetite nanoparticles have serious toxicological effects in vivo . Some doses from NPs improve blood picture during 2 weeks but change in histopathology examinations were occur in some groups within 2 weeks. Nanoparticles were considered the toxicological hazards especially the size of less than 54 nm.
