ELEMENTOS TRAÇO ASSOCIADOS AO RISCO DE ACIDENTE VASCULAR ENCEFÁLICO (AVE)

Abstract

The trace elements analysis (mineral content) of the organism by hair sampling can demonstrate metabolism disorder which can lead to several diseases. This present study had as objective to evaluate the relations between the risk of encephalic vascular accident occurrence and the essential trace elements, nonessential and toxical elements, determined by hair sampling. Forty volunteered subjects took part in the study, 20 of them being immediate encephalic vascular accident patients (study group), diagnosed by image exam and twenty apparently healthy subjects as the control group. The concentrations of 31 elements : Ag, Al, As, B, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sb, Sc, Se, Sn, Sr, Ti, V, Y, Zn e Zr in hair sampling were determined by induced plasma spectrochemical analysis of atomic emission of argony (ICP-OES) and atomic mass spectometry (ICP-MS). For the sampling characterization it was utilized medium and deviation pattern. The group study sampling is combined amongst themselves, generating a figure (dendograme) that facilitates combined patterns scanning. The significance level was defined as p = 0,05. The results of this study indicated high levels of Zn in most subjects suffering EVA, demonstrating the correlation between these two variables. Therefore, this trace element in high levels can represent a risk factor for the occurrence of this neurological condition.
