Title in Portuguese
Avaliação química e termoanalítica de cálculos biliares e bile vesicular humana de pacientes do sexo masculino
Keywords in Portuguese
Cálculos vesicais (Análise Química)
Colelitíase (Estudo Clínico)
Método termoanalítico (Aplicações)
Abstract in Portuguese
Este trabalho teve como meta principal ampliar o estudo anteriormente relatado por Mercuri em 2000, agora com a caracterização química e termoanalítica de cálculos biliares e as biles vesiculares humanas, especificamente, de pacientes do sexo masculino. Para ambos os tipos de caracterização foram utilizadas várias técnicas, como: (a) Análise Elementar (AE), para determinação de teores de C, H e N. (b) Espectroscopia no infravermelho com transformada de Fourier (FTIR), com o objetivo de verificar as bandas de absorção no IV e assim identificar algumas substâncias que fazem parte desses materiais. (c) Difratometria de Raios X (DRX), para identificar formações cristalinas de espécies presentes nas amostras de cálculos biliares. (d) Espectrometria de Absorção Atômica (AAS), para a determinação do teor de alguns metais como por exemplo: Cd, Pb e Cu. (e) Ressonância Magnética Nuclear (RMN), para ratificar a presença de colesterol e afastar a hipótese de ter-se ergosterol na amostra e (f) TG/DTG e DSC aplicadas para o estudo do comportamento térmico das amostras de cálculos biliares e biles. Este trabalho permitiu concluir que: alguns tipos de cálculos biliares do universo de pacientes do sexo masculino que foram estudados puderam ser inseridos na classificação proposta anteriormente, no entanto, cinco dessas amostras não se encaixaram em nenhum desses grupos, sugerindo, com isso, a adição de novos grupos. Verificou-se, também, que a porcentagem de cálculos biliares formados por colesterol é menor para essa classe de pacientes. Em duas amostras de cálculos biliares encontrou-se CaCO3 cristalizado como aragonita, outra indicou a presença de fosfato de cálcio e em duas dessas amostras foram encontrados um alto teor de chumbo. No caso das biles, seis amostras indicaram a presença de NaCl (halita) e uma delas indicou, também, a presença de colesterol.

Abstract in English
This work had as goal main to enlarge the study previously related for Mercuri in 2000, now with the chemical and thermoanalytical characterization of gallstones and the human vesicular bile, specifically, of patient of the masculine sex. For both the kinds of characterization were used several techniques, as: (a) Elementary analysis (AE), for contents determination of C, H and N. (b) Fourier Transform Infrared Spectroscopy (FTIR), with objective of verifying the absorption bands in the IV and thus identify some substances that do part of these materials. (c) X-rays diffraction (DRX), to identify present crystalline species formations in the gallstones sample. (d) Atomic Absorption Spectrometry (AAS), for some metals content determination such as: Cd, Pb and Cu. (e) Nuclear Magnetic resonance (RMN), to ratify the cholesterol presence and to remove the hypothesis of have ergosterol in the sample and (f) TG/DTG and DSC applied to the gallstones and bile samples thermal behavior study. This work allowed to conclude that: some universe gallstones kinds of patient of the masculine sex that were studied could be inserted in the proposed classification previously, however, five of these samples did not case in none of these groups, suggesting, with that, the addition of new groups. It verified, also, that the gallstones percentage formatted for cholesterol is smaller for this class of patient. In two gallstones samples were found CaCO3 crystallized as aragonite, other indicated the calcium phosphate presence and in two of these samples were found a Pb high content. In the biles case, six samples indicated presence of NaCl (halita) and their one indicated, also, the cholesterol presence.
