Degranulação de neutrófilos ex-vivo por ação do polímero de amido de mandioca

The neutrophils play an essential role in host defenses against infection. When stimulated it responds with an increase of consumption of oxygen known as 'respiratory burst', so generating a great quantity of superoxide anion and hydrogen peroxide, which play an important function antimicrobial, and subsequent degranulation of neutrophils. Polymers are materials largely used in veterinary medicine. Several studies have been carried out to find new polymers and their biocompatibility to medical use. One polymer of cassava's starch (Manihot esculenta crantz) was developed at the Paranaense University's Laboratory of Chemistry - Campus Umuarama City, aiming to analyze the neutrophils degranulation after exposition to this starch. The early results showed a bioinert action of the polymer of cassava's starch on different concentrations when it was in contact with neutrophils. Thus, this material is potentially indicated as biomaterial.
