The glial cell contents of S lOO protein, 2′3′‐cyclic AMP, 3′‐ phosphohydrolase (CNP), isoenzyme II of carbonic anhydrase (CAII) and butyrylcholinesterase (BuChE) were biochemically determined in the cerebellum and cerebrum of the reeler mutant mouse. Astrocytes and oligodendrocytes, shown by this study, contain abnormal amounts of these components. The CAII concentration was significantly increased in the particulate fraction of the reeler cerebellum and cerebrum (by 50% and 89%, respectively). The BuChE specific activity was greatly increased in the reeler, by 120% for cerebellum and by 40% in cerebrum. In contrast, the SlOO protein concentration was reduced in the reeler cerebellum by 40% and by 25% in cerebrum, while the CNP specific activity increased by 30% in the reeler cerebellum. In addition, the glial cell distribution was studied by immunohistological techniques with antibodies directed against S 100 protein, glial fibrillary acidic protein (GFA) and CAII. Apparently the density of glial cells is not significantly affected. However, the Golgi epithelial cells were usually abnormally placed and their Bergmann fibres were less well developed.
