Artigo IPEN-doc 26908 Determination of inorganic elements in blood of mice immunized with Bothrops Snake venom using XRF and NAA2015 - SILVA, L.F.F.L. da; ZAMBONI, C.B.; BAHOVSCHI, V.; METAIRON, S.; SUZUKI, M.F.; SANTANNA, O.A.; RIZZUTTO, M.A.In this work, mice genetically modified [HIII line] were immunized against different Bothrops snake venoms to produce anti-Bothrops serum (antivenom). The Neutron Activation Analysis (NAA) and Energy Dispersive X-Ray Fluorescence (EDXRF) techniques were used to evaluate Ca and Fe concentrations in blood of these immunized mice in order to establish a potential correlation between both phenotypes: antibody response and blood constituents after Bothrops venom administration. The results were compared with the control group (mice not immunized) and with human being estimative. These data are important for clinical screening of patients submitted to immunological therapy as well as the understanding of the envenoming mechanisms.Resumo IPEN-doc 24549 Differences in iron concentrations in whole blood of animals model using NAA2017 - SILVA, L.F.F.L.; ZAMBONI, C.B.; BAHOVSCHI, V.; METAIRON, S.; MEDEIROS, I.M.M.A.In this study Neutron Activation Analysis technique (NAA) was applied to determine Fe concentrations in whole blood samples of several animals model: mice (Mus musculus), Golden Hamsters (Mesocricetus auratus), Wistar rats, Albinic Rabbits of New Zealand, Golden Retriever dogs and Crioula breed horses. In the health area these animals model are used for several investigations, mainly those that involve testing of new medicines, vaccines, antibiotics, anesthetics, antidepressants, organs transplantation as well as medical diagnostic studies. While small-sized animals model (mice, hamsters, rats and rabbits ) are very convenient to perform medical investigation due to the low cost, easy handling and medico-legal implications, medium and large sized animals, (mainly Golden Retrievers dogs) are selected for medical diagnostic studies because of their physiological similarities with the humans. Particularly, in this study, horses (Crioula breed) were also investigated because they are frequently used for antivenom production in Brazil. An important aspect to be considered during these medical investigations is the needs to check for similarities between the animal’s blood and the human’s blood. Besides, considering that Fe plays important functions in blood (acts as indicator of a great number of anomalies) consulting these data is possible to select the convenient animal model for experiments which the similarities with the humans are an important condition. The NAA measurements were performed in the nuclear reactor IEA-R1 (3.5-4.5MW, pool type) at IPEN/CNEN-SP (Brazil). Fe concentrations results in the blood of these animals were compared with human blood estimative and some significant differences were identified.Resumo IPEN-doc 22962 Uso do Espectrômetro compacto de FRX como alternativa para prática clínica2016 - SILVA, LAIS de F.F.L. da; ZAMBONI, CIBELE B.Artigo IPEN-doc 22408 Inorganic elements in blood of mice immunized with snake venom using NAA and XRF techniques2016 - METAIRON, S.; ZAMBONI, C.B.; SUZUKI, M.F.; SILVA, L.F.F.L. da; RIZZUTTO, M.A.Resumo IPEN-doc 21471 Uso de espectrômetro compacto de fluorescência de raios X como alternativa para prática clinica2015 - SILVA, LAIS de F.F.L. da; ZAMBONI, CIBELE B.
