[Corpora amylacea in the human brain (author's transl)].

130.5 mg of almost pure corpora amylacea was isolated from lyophilized tissue of 35 human brains obtained by autopsy. Staining shaved this material to be homogenous. The greater part of this material is composed of carbohydrates, whereas the protein- and lipid content is small. With regard to composition, one can take for granted that this material is different from amyloid and from the corpora amylacea of the prostatic gland. It may be assumed that corpora amylacea of the brain are caused by the glucose requirement of the brain being reduced, while the supply of glucose for the brain is normal.
