Dendritic Inclusions in the Cerebellar Granular Layer after Long Term Alcohol Consumption in Adult Rats.

Whorled multiplanal inclusions up to 1.5 μm in diameter were observed in dendrites of the cerebellar Goigi cells after 6 months of alcohol treatment, increasing in number with time. Inclusions are formed by apposed cytomembranes stacked parallel or In a twisted arrangement The paired membranes merged into a dense, finely textured material. A close relationship with dendritic smooth endoplasmic reticulum is apparent A correlation between chronic alcohol intake and the development of these inclusions is shown although, in common with many other types of neuronal cytoplasmic inclusions, their genesis and function remains to be determined.
