    Notes: Summary Data concerning width and surface of the basement membrane of cortical capillaries in three patients with Alzheimer's disease five age-matched controls, have been submitted to statistical analysis to ascertain the role of the aging process upon thickening of the basement membrane itself. The analysis showed that there was a significant difference between patients with Alzheimer's disease and controls (P〈0.01) as to both width and surface of the basement membrane, so suggesting that in these patients aging was not the only factor which thickening of the basement membrane of cortical capillaries was related to.

    Notes: Summary The distribution of phenotypic and allelic frequencies of red blood cells aminolevulinate dehydrase in several Italian populations is reported. The frequency of the most common allele ALADH 1 ranges from 0.78 to 0.93 with a mean value of 0.90±0.01.

    Description / Table of Contents: Zusammenfassung In 90 Fällen von amyotrophischer Lateralsklerose und bei 50 auch im Alter entsprechenden Kontrollen wurde der Liquor untersucht. Der Eiweißgehalt war bei den Patienten mit ALS signifikant höher als bei den Kontrollen. Die Albuminfraktion und das IgG, die mit Immunodiffusionsmethoden quantitativ bestimmt wurden, waren bei der ALS im Liquor signifikant erhöht, während sie sich im Serum gleich wie bei den Kontrollfällen verhielten. Bei der isoelektrischen Fokusierung ließ sich ein eindeutiges „Finger-print-pattern“ in elf von zwölf Fällen beobachten. Diese Befunde sprechen dafür, daß bei der ALS eine Störung der Blut-Hirnschranke vorliegt. Es wird kurz auf die Beobachtung einer vermehrten Zahl mononukleärer Zellen bei jungen Patienten mit ALS eingegangen und im besonderen die Frage diskutiert, in wieweit ein exogenes Agents in der Pathogenese eine Rolle spielen könnte. Mindestens eines der obern erwähnten Parameter war bei 45% aller ALS Fälle im Liquor verändert.
    Notes: Summary The cerebrospinal fluid (CSF) was examined in 90 amyotrophic lateral sclerosis (ALS) patients and in 50 age-matched normal controls. Total protein concentration was significantly higher in ALS patients than in normal controls. CSF IgG and albumin, quantitatively determined by single radial immunodiffusion, were significantly increased in ALS. No difference in serum concentrations was observed between ALS patients and normal controls. On isoelectric focusing a clear-cut “fingerprint” pattern was observed in 11 of 12 cases. These findings support the hypothesis that blood-brain barrier damage occurs in ALS. The finding of a higher mononuclear cell count in young ALS patients is briefly discussed in the light of the hypothesis that an exogenous agent might be of some relevance in pathogenesis. An alteration of at least one of the CSF parameters considered was found in 45.5% of ALS cases.

    Description / Table of Contents: Zusammenfassung Bei der Autopsie eines 8 Monate alten Kindes, welches infolge einer schweren Gastroenteritis verstarb, fanden sich in der Kleinhirnrinde degenerative Veränderungen mit Befall von Zellen des äußeren Stratum granulare, aber auch der Purkinje- und Golgi II-Zellen. Noch erhaltene Purkinje-Zellen zeigten vakuoläre Veränderungen des Zellkörpers und Anomalien der Dendriten. Zugeordnete Veränderungen fanden sich in den unteren Oliven und in den Moos-Fasern.
    Notes: Summary An 8 month old infant, who died of severe gastroenteritis, presented a degeneration of the cerebellar cortex involving cells arising from the outer granular layer as well as Purkinje and Golgi II cells. Residual Purkinje cells showed vacuolar change of the cell body and dendritic abnormalities. Related lesions were atrophy of the inferior olives and degeneration of the mossy fibers.

    Description / Table of Contents: Sommario Una grande quantità di neuroni in degenerazione neurofibrillare e di placche senili, fu trovata nella corteccia cerebrale di una donna di 52 anni affetta da una demenza ad evoluzione subacuta, mioclonie e alterazioni elettroencefalografiche periodiche. È questo un caso sporadico di demenza presenile di Alzheimer clinicamente sovrapponibile alla malattia di Creutzfeldt-Jakob, che si presta a ipotizzare un rapporto fra quella malattia e le demenze trasmissibili.
    Notes: Abstract Large numbers of neurofibrillary tangles and neuritic plaques were found in a cerebral biopsy from a 52-year-old woman suffering from subacute dementia with early myoclonus and quasiperiodic EEG changes. This case, which appeared to be an example of non-familial Alzheimer's disease, is commented in the context of possible relation of Alzheimer's disease to transmissible dementia.
