[Histotopochemical investigations on elastic membranes of blood vessels with special regard of diabetes mellitus. iv. Heavy metals (author's transl)].

Both of the methods for the histochemical detection of heavy metals have given corresponding results. In normal animals and also in non-diabetic men was a visible strong fluorescence after application of 2-methyl-8-hydroxychinoline and a strong sulfide-silver-reaction. This results are also in animals with diabetes mellitus clear. In asymptomatical and clinical manifest diabetes mellitus is established in contrast a weak exhibition of the elastic membranes of vessels with both of the methods.
