[Contribution to the atypical macroglia in nonhepatic diseases (author's transl)].

Frequency and appearance of atypical macroglia in the frontal cortex and striatum in 400 human brains of cases with non-hepatogenic diseases were investigated and compared with results in 150 human brains of cases with severe liver diseases. Quantitative and qualitative differences between the non-hepatogenic (I---III) and hepatogenic (IV) groups were statistically significant. Evidence for the so-called Alzheimer-II-cells could only be obtained in metobolic disturbances of hepatogenic origin and in a few cases of cerebral coma.
