    Description / Table of Contents: Résumé L'étude neuropathologique de la corne d'Ammon, en particulier dans le secteur de Sommer, au cours des encéphalopathies cirrhotiques alcooliques met en évidence deux sortes de faits bien distincts. Dans les neurones pyramidaux de la couche CA1, profondément dégénérés, il existe d'indiscutables filaments groupés par paire et de forme hélicoïdale, qui correspondent aux désormais classiques ≪ paired helical filaments ≫. D'autre part, alors que la population astrocytaire dans son ensemble présente les manifestations caractéristiques de ce qu'il est convenu d'appeler les cellules de type II d'Alzheimer, il subsiste un certain nombre de foyers de haute réactivité, objectivables par une méthode immunohistochimique spécifique de la GFAP.
    Notes: Summary Two distinct categories of facts are deduced from a neuropathological study of the Ammon's horn, in particular the Sommer Sector, afflicted with alcoholic cirrhotic encephalopathy. In the pyramidal neurons of the CA1 layer, there are unquestionably paired filaments in a helical form, which correspond to the now classic “ paired helical filaments ”. On the other hand, whereas the astrocyte population on the whole displays the characteristics of what can be called Alzheimer type II cells, a certain number of highly reactive areas persist, which can be detected by a GFAP-specific immunohistochemical method.

    Notes: Summary Newborn rats received an intracisternal injection of 6-hydroxydopamine (100 μg) within 16 h after birth. Treatment effects upon noradrenaline uptake (with or without desmethylimipramine pre-incubation), endogenous noradrenaline, dopamine, and serotonin were biochemically assayed. Noradrenaline uptake and endogenous noradrenaline content were permanently reduced to less than 5% of control values. Reduction of endogenous dopamine content was less marked: at day 60, values were about 40% of controls. Serotonin content remained unaffected. Cell density countings in postnatal day 15 temporal cortex revealed an about 16% reduction in layers II and III of treated animals. These modifications of cortical geometry were discussed with reference to measurements of cortical thickness and ultrastructural observations on postnatal days 2, 5 and 15. Both supranormal involution and growth processes might result from the neurotoxin treatment. Whereas some of the degeneration processes might be due to general cytotoxic effects, this is less likely for the supranormal growth processes.

    Notes: Summary The neuropathologic study of an alcoholic cirrhotic encephalopathy was made after the fixation of the brain by immersion in a solution specially prepared for the electronic microscopy. The histological technics were used then, the Golgi-Cox method among others, confirmed the classic notions of neuronal rarefaction and of the proliferation of the glia cells, particularly in the cerebral cortex. The Bodian method for its part showed in the remaining cortical neuronic population, the existence of voluminous intracytoplasmic aggregates and the hypertrophy of the dendritic apparatus.
