  abstract  = {A rapid method for macroscopic and microscopic investigation of human CNS is proposed. After fonnalin fixation, gelatin or agarose embedding, and cryoprotective treatment, frozen human spinal cords, brainstems, or hemispheres can be serially cut into 0.7 mm thick slices. Stained with gallocyanin-chromalum, these slices facilitate cytoarchitectonic, neuropathologic, and quantitative examination. Regions of interest from parallel fonnalin-stored unstained slices can be embedded into paraffin and stained by any irnrnunocytologic and histologic stain compatible with fonnalin fixation and paraffin embedding.},

  abstract  = {Ultrastructural changes including reduced electron density, reduction in polysemes and cisternae of rough endoplasmic reticulum occur in the cytoplasrn of endothelial cells and pericytes in the cerebellar cortex of senile virgin female Han: WIST-rats in cornparison to 3-month old virgin rats. Processes of pericytes cover less of the capillary surface in the cerebellar cortex of senile rats; moreover, arithmetic and harmonic mean thickness of the endothelium and relative volume of mitochondria in endothelial cells and pericytes are reduced, w hereas the luminal diameter of the capillaries, harmonic and arithmetic mean thickness of pericytes and their processes and of the basal laminae between endothelial cells and astrocytes (abbreviated BAL 1), pericytes and astrocytes (BAL 2) and endothelial cells and pericytes (BAL 3) increase. The increase in harmonic mean thickness of the basal laminae is statistically significant (α<=0.05) and compensates for a decrease in thickness of capillary endothelium. Consequently, the total barrier mass and thickness of cerebellar cortical capillaries in senile animals is higher than in young individuals.},
