    Description / Table of Contents: Sommario Gli autori riportano lo studio clinico e biochimico di un caso di malattia di Krabbe tardiva. L'esordio acuto dei sintomi neurologici, dopo una affezione febbrile respiratoria, il profilo immunochimico del liquor con produzione locale di IgG e la risposta iniziale al trattamento con ACTH hanno fatto supporre una genesi infiammatoria. È stata tuttavia diagnosticata in seguito una malattia di Krabbe. Gli Autori discutono brevemente il significato di una possibile produzione di IgG nel Sistema Nervoso Centrale in questo caso.
    Notes: Abstract During a febrile upper respiratory tract illness this 4 year old boy developed left hemiparesis, which progressed to loss of walking and even of sitting finally to tetraplegia. The cerebrospinal fluid protein pattern showed blood-brain barrier damage with additional intrathecal IgG synthesis. The symptoms responded to steroid therapy but resumed and worsened on withdrawal. Only late, when visual evoked potentials and nerve conduction velocity proved to be impaired, was Krabbe disease diagnosed on the assay of cultured fibroblasts for galactocerebroside-beta-galactosidase. We discuss the significance of possible endogenous production of IgG in the CNS.

    Description / Table of Contents: Sommario Campioni di liquido cefalo-rachidiano di pazienti analizzati per casi di sospette malattie neurologiche sono stati separati nella componente macromolecolare (Peso Molecolare 〉3000 Daltons) ed in quella delle piccole molecole (PM〈3000 Daltons). La c omponente macromolecolare è stata testata per la sua possibile interferenza con l'accumulo di36Cl−, stimolato dal GABA, in “microsacs” della corteccia cerebrale di ratto. Per molte patologie non è stata rilevata alcuna interferenza. Fanno eccezione i pochi (2) casi di morbo di Parkinson; in entrambi i casi vi è una chiara stimolazione dell'attività GABAergica. Quest' ultima indicazione sembra degna di ulteriori indagini.
    Notes: Abstract Cerebrospinal fluid (CSF) samples from patients undergoing lumbar puncture for suspected neurological diseases were fractioned into macromolecular (MW〉3000 Daltons) and small molecule components (MW〈3000 Daltons). The macromolecular component was tested for its interference with GABA stimulation of36Cl− accumulation in rat cerebral cortex microsacs. For many pathologies, no interference was apparent; an exception was two patients with Parkinson's disease in whom there were clear signs of stimulated GABA activity. This last result seems worthy of further investigation.
