    Proliferation of blood vessels and stroma in brain tumours (1976)
    Springer
    Virchows Archiv 372 (1976), S. 175-182

    Thema: Medizin
    Notizen: Summary Proliferation of the vascular endothelium occurring in brain tumours is accompanied by a proliferation of histiocytes in the peripheral part of the vessel wall. These histiocytes infiltrate the tumour tissue in a very regular pattern. Enzyme-histochemically, there are marked differences between the activities of alkaline phosphatase, 5-nucleotidase, and ATPase in the normal and proliferating blood vessels. The whole process encompasses reactive changes evoked by the destroyed perivascular sheath of astroglial foot processes and the subsequent oedema in the tumour and the surrounding parenchyma. There are often tumour areas where diminished vascular permeability is established by proliferation of perivascular connective tissue. Here the oedema has completely disappeared. A clearcut influx of monocytes from the blood into the vessel wall is seen only in the vicinity of necrotic foci; the number of histiocytes is increased and their turnover is observed in swollen macrophages. In the rest of the tumour influx of monocytes and activity of macrophages are inconspicious.

    Acetylcholinesterase-activity in rectal mucosa of children with obstipation (1977)

    Thema: Medizin
    Notizen: Summary The results are presented of a clinical-enzyme histochemical evaluation of the activity of acetylcholinesterase in the rectal mucosa of 46 children with obstipation. In four cases abundant and coarse acetylcholinesterase positive nerve fibres were present in the lamina propria of the mucosa. Only in these 4 cases was the diagnosis of Hirschsprung's disease supported by the clinical course. Local accumulations of fine acetylcholinesterase positive nerve fibres or accumulations of acetylcholinesterase positive foamy or structureless material were not correlated with Hirschsprung's disease.

    The influence of preoperative administration of methotrexate on the outgrowth of meningiomas and astrocytomas in tissue culture (1980)
    Springer
    Acta neurochirurgica 54 (1980), S. 201-204

    Thema: Medizin
    Notizen: Summary Explants from 30 human meningiomas and 29 human malignant astrocytomas (i.e., glioblastomas multiforme) were grown in tissue culture for four weeks. After preoperative administration of 50 mg methotrexate (MTX) to the patients outgrowth of the meningiomas in tissue culture was markedly inhibited, but a similar effect was not seen for the astrocytomas.

    An intrasellar cyst with both Rathke's cleft and epidermoid characteristics (1980)
    Springer
    Acta neurochirurgica 51 (1980), S. 203-207 
    Details
    ISSN: 0942-0940
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary A case of an intrasellar cyst in a 48-year-old woman is reported. The cyst was lined by stratified squamous epithelium, most of which was covered by ciliated columnar epithelium. Most of the stratified squamous epithelium showed necrosis accompanied by signs of an acute inflammatory reaction. After surgical resection aseptic meningitis developed. The lumbar CSF findings were still abnormal four months after the operation.

    Notizen: Summary Ultrastructural analysis of the ncl. accumbens, frontal cortex, and caudate nucleus of ten patients with Huntington's chorea revealed nuclear membrane indentation of remaining neuronal elements in 〉25%, 〈5%, and 〈2%, respectively. This phenomenon was not observed in ten non-choreic control brains obtained from patients with Alzheimer's disease, Parkinson's disease, and non-demented elderly people. The pathogenetic mechanisms leading to this phenomenon are discussed.

    Differences in the distribution of β-glucuronidase activity demonstrated with the Fishman-Baker method in the adrenal cortex of albino rats treated with corticosteroids and after hypophysectomy (1965)
    Springer
    Histochemistry and cell biology 5 (1965), S. 244-249

    ISSN: 1432-119X
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Medizin
    Notizen: Summary Histohemical estimation of β-glucuronidase was performed in the adrenals of normal rats, rats treated with corticosteroids and hypophysectomized rats. In these experiments the method described by Fishman and Baker was used. A difference was found between normal rats and rats treated with hydrocortisone and corticosterone on the one hand and hypophysectomized animals on the other. In the first group a positive reaction was found in the zona intermedia, the zona fasciculata, and the zona reticularis. In the second group a positive reaction was found in the male animals exclusively in the zona intermedia and in the female animals in both the zona intermedia and the zona glomerulosa. Although the distribution of the blue precipitate in the adrenal cortex of untreated rats is similar to the distribution of β-glucuronidase as determined histo-biochemically by Nayyar and Glick we doubt, in spite of the observed difference, that the Fishman-Baker method is specific for β-glucuronidase. Replacement of the specific substance 8-hydroxyquinoline glucuronide by 8-hydroxyquinoline did not affect the results.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Drei Fälle von Thrombose der Vena magna Galeni werden veröffentlicht. Keine Thrombose anderer Venen oder Sinus durales war vorhanden. Alle drei Fälle waren Frauen. Bei einer Patientin berichtete die Anamnese den Gebrauch eines oralen Kontraceptivum (Lyndiol®). Bei einer anderen traten die Symptome nach Gebrauch von Amitriptylinepamoat (Tryptizol®) auf. Die dritte Patientin litt an Polycytämie, bei der die Thrombose nach Schädelfraktur auftrat. In der Literatur des letzten Jahrhunderts sind keine anderen Fälle verzeichnet, vermutlich weil die klinische Diagnose sehr schweirig ist.
    Notizen: Summary Three cases of thrombosis of the Galenic system veins in adults are presented. Thrombosis of other veins or the venous sinuses was not found. All three patients were women, only one of whom used oral contraception (Lyndiol®). In another of these cases treatment with amitriptylinepamoate (Tryptizol®) seemed to have initiated the symptoms. In the third case, a patient with polycythaemia, the thrombosis developed after a cranial fracture. No other cases of this kind are reported in the literature of this century.
