Determination of inorganic elements in blood of mice immunized with Bothrops Snake venom using XRF and NAA

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.
