[Ultrathin sections in postmortem morphological diagnosis of kidney diseases].

Authors for the light-microscopic examination of various--mainly glomerular--diseases of kidneys in addition to paraffin section have used also ultrathin sections (0,5 mu). Material was fixed in buffered-formalin solution and embedded in metacrylate or Durcupan ACM. Sections obtained by this method can be studied by electron micro-scope as well. Sections were stained with methylene-blue and basicfuchsine, further with periodic-acid silver methenamine. The use of ultrathin sections for the light-microscopic studies can not replace the study of paraffin-sections. Ultrathin sections are suitable for the detection of fine details. They can be studied by light- and electron microscopy as well.
