to inform healthcare professionals of a rare serious reaction leading to leg amputation following intramuscular injection of iron dextran and report comments for preventing such reactions.a case of leg amputation following intramuscular injection of iron dextran reported to iranian pharmacovigilance center was reviewed. patient and reaction data was collected by assessing the reported yellow ca...

Interactions of fibrinogen with dextran sulfate, dextran, and carboxymethyl cellulose were investigated by turbidity measurement, chemical analysis, and electrophoresis. Dextran sulfate and fibrinogen combined even in the physiological pH region where both of them have negative net charges, and formed a precipitate and soluble complex. Since no complex formation was observed in the case of dext...

The effect of dextran sulfate on protein aggregation was investigated to provide the clues of its biochemical mechanism. The interaction between dextran sulfate and BSA varied with the pH values of the solution, which led to the different extent of aggregation prevention by dextran sulfate. Light scattering data with thermal scan showed that dextran sulfate suppressed BSA aggregation at pH 5.1 ...

Intravenous iron preparations are typically classified as non-dextran-based or dextran/dextran-based complexes. The carbohydrate shell for each of these preparations is unique and is key in determining the various physicochemical properties, the metabolic pathway, and the immunogenicity of the iron-carbohydrate complex. As intravenous dextran can cause severe, antibody-mediated dextran-induced ...

A complex between soluble dextran and human hemoglobin has been synthesized by two different methods. In the alkylation method, hemoglobin was allowed to react with bromoacetyl groups incorporated into the dextran; the yield of the complex was about 80% in terms of the hemoglobin used. In the dialdehyde method, hemoglobin was allowed to react with dialdehyde groups on the dextran generated by p...

BACKGROUND We previously compared the safety profile of three formulations of intravenous iron used during 1998-2000 and found higher rates of adverse drug events (ADEs) associated with the use of higher molecular weight iron dextran and sodium ferric gluconate complex compared with lower molecular weight iron dextran. Since that time, iron sucrose has become widely available and clinicians hav...

in the present study, the production of dextran from date extract and sucrose as carbon sources by the bacterium leuconostoc mesenteroides nrrl b512 (f) was investigated. in comparison to blue dextran (mw≈2000 da), dextran molecular weight was reduced (mw2000 kda). flow behavior indices of dextran solutions from date extracts were investigated and rheological parameters were evaluated at concen...
