Effect of Denzimol, a new anticonvulsant drug, on rat cerebellum. Morphological and histochemical patterns of Purkinje cell layer.
The effects of Denzimol, a new anticonvulsant drug, were analyzed in the Purkinje cell layer of rat cerebellum. No modifications in the general histochemical and ultrastructural patterns were induced by chronic administration of the drug. A slight increase in the storage of lipopigments in the cytoplasm of Purkinje neurons was found. No effects on secondary fluorescence (indicative of changes in biogenic amines) were found while an increase in specific SSADH activity, a degradative enzyme in GABA metabolism was present. Some observed histological and ultrastructural alterations (presence of "balloned" Purkinje neurons showing, in particular, enlarged cisternae of the endoplasmic reticulum) may be a stress effect probably due to the gastric tube insertion by which the drug was administered.
