[Histotopochemical investigations on elastic membranes of blood vessels with special regard to diabetes mellitus. III. Lipids (author's transl)].

Lipids have been investigated in the light microscope with Scarlet-Blue and for the fluorescentmicroscopy with rhodamine B and sulforhodamine B. Both of these reactions gave weak results. After using nilblue-sulfate for the detecting of acid and neutral lipids the presence of acid lipids could be shown in the walls of the vessels of normoglycemic men and animals. In the asymptomatical diabetes the tinction of elastic membranes was more intensive. Both acid and neutral lipids are present in a higher concentration in this stadium of diabetes mellitus as well as in the manifest diabetes of man.
