abstract = {Aims: of this investigation were to quantify copper (Cu),
iron (Fe) and zinc (Zn) along with sulphur (S) andphosphorus
(P) in hepatocytes and connective tissue in liver section
from patients with Wilson´s disease (WD) bymicro
Synchrotron X-ray fluorescence (μ-SRXRF). Secondly to
establish two-dimensional μ-SRXRF elementmappings for
comparison with histologically prepared slices, and thirdly
to assess whether elemental distribu-tions are
associated.Methods: Archival liver tissues from twelve
patients with end-stage cirrhosis or fulminant WD were
investigated.Mutations in ATP7B have been classified
before. For control seven archived normal liver tissues were
in-vestigated. μ-SRXRF measurements were performed at the
DORIS III storage ring at HASYLAB/DESY (Hamburg,Germany).
Two-dimensional element distribution were compared with
histologically prepared slices about20–30 μm apart from
those investigated by μ-SRXRF.Results: Elementary copper
(Cu) could be demonstrated in all investigated liver
sections simultaneously with Fe,Zn, P and S. In WD mean Cu
was 20 fold increased in hepatocytes and threefold in
fibrotic areas in comparisonwith controls. In regeneration
nodules Cu was strikingly inhomogeneous distributed. Cu
concentrations mea-sured by μ-SRXRF correlated with those
measured by atom absorption spectroscopy. Strong
associations in theirregional distribution existed between
Zn and Cu or Fe and S. Moreover, differences in Cu/S were
found betweenhepatocytes and fibrotic areas. An increase of
Fe could only be documented in hepatocytes compared to
fibroticareas. With a beam size of 15 x 15 μm
two-dimensional distributions of these elements are
morphologicallycomparable with histological section with a
magnification of about 25x optic microscope.Conclusions:
μ-SRXRF investigations are a valuable tool for quantifying
element concentrations in biologicaltissues and further
provide 2-dimensional information of element distribution
and elemental association in abiological tissues, thus
speeding up basic knowledge in a synopsis with biological
and clinical data.},
