T1  - Regionale Unterschiede der numerischen Purkinje-Zell-Dichte in Kleinhirnen von Albinoratten zweier Stämme
N2  - The total number and the number of Purkinje cells per square millimeter of the surface of the cerebellar granular layer were measured in albino rats from two strains: Chbb-THOM-Wist and Han: SPRD. The total number of the Purkinje cells in the cerebellar vermian lobules L land L X with the exception of cells in the lobules VIb + c did not. differ significantly. Statistically significant differences were found between the individuals of the two rat strains and within single lobules of the cerebella concerning the cell density of Purkinje cells per square millimeter surface of the granular layer. The results suggest heterogeneity of the cerebellar cortex between cerebellar lobules and between albino rats derived from different strains.

T1  - Regional differences in the distribution of lipofuscin in Purkinje cell perikarya : a quantitative Pigmentarchitectonic study of the Cerebellar Cortexof Senile Albino Rats
N2  - The distribution of lipofuscin in the perikarya of Purkin je cells of vermal and hemispheric lobules has been determined quantitatively in 7 rats, 30-38 months old, by the point-counting method. On the basis of morphologically and statistically significant differences a pigmentarchitectonics of the cerebellar cortex is established. The Purkinje cells of lobule VIa (Larsell 1952) are extremely lipofuscin-rich. The Purkinje cells of the hemispheres, lobules V, Vlb + c and VII contain considerable amounts of a finely granular lipofuscin, the Purkinje cells of lobules I-III and VIII- IXa a globular type of lipofuscin. The Purkinje cells of sublobule XI d c and X are lipofuscin-poor cells. Three types of lipofuscin ha ve been identified in the light microscope.
