Resumo
Small-sized animals are currently used on investigations for new medicines, vaccines or antibiotics
before being tested in human. In this study the semi-parametric Neutron Activation Analysis [NAA]
technique was used to determine simultaneously the whole blood concentrations of elements that
are important for clinical analysis in the Dmd mdx [Duchenne muscular dystrophy] mouse strain. The
relevancy of this study is that blood represents the most important biological referential of
circulatory system condition and alterations in its ion concentration represents an important tool for
medical investigation. It permits also to check the similarities between this mouse strain and the
human whole blood estimation values. Blood samples were collected by the retro—orbital venous
plexus from eleven adult mice and the individual biological samples [100µ1 whole blood spread in a
filter paper] were sealed into individual polyethylene bag, together with the Au detectors used for
the measurement of the flux distribution, and irradiated in the nuclear reactor (IEA-R1, 2-4MW,
poop type). The activated materials are gamma-counted using an HPGe spectrometer and the
concentration obtained by using in-house software. According to these results, Br and K levels of
this isogenic mouse are altered in relation to human reference values. This procedure is an efficient
alternative to perform synchronized and quantitative analysis of several blood elements.
