    Description / Table of Contents: Summary The purpose of this case report is to describe chronic encapsulated intracerebral hematoma (CEIH), a rare and not fully understood brain lesion. The differentiation from chronic cerebral hematoma, cerebral abscess, and intra-axial tumor is based on clinical and imaging criteria. The diagnosis is confirmed by histological analysis. In the English medical literature, we found 39 patients reported with this lesion. The key feature is the formation of a capsule between a hematoma and cerebral parenchyma. The reasons for this formation are not known. In our patient, an arteriovenous malformation was located outside but adjacent to the CEIH.
    Notes: Zusammenfassung Ziel der Arbeit ist es, die seltene Erkrankung des chronisch eingekapselten intrazerebralen Hämatoms (CEIH) zu erläutern, sie vom chronisch intrazerebralen Hämatom (CIH) klinisch und vom zerebralen Abszess und Tumor mittels der bildgebenden Diagnostik abzugrenzen und die histologischen Befunde zu definieren, die die Diagnose bestätigen. In der englischsprachigen Literatur sind 39 Patienten mit dieser Erkrankung beschrieben. Im Unterschied zu den akuten und chronischen intrazerebralen Hämatomen bildet sich beim CEIH aus unbekannten Gründen eine Kapsel. Anhand der Kasuistik einer eigenen Patientin und der vorliegenden Fallmitteilungen werden die charakteristischen Merkmale des CEIH erläutert. Die Besonderheit des eigenen Falles ist der histologische Nachweis der die Blutung verursachenden Gefäßmissbildung außerhalb der Hämatomhöhle.

    Description / Table of Contents: Summary Rats were poisoned by intraperitoneal mercuric chloride (0.3 mgm/100 gm body weight). Their kidneys were examined at intervals (from 5 minutes to 48 hrs. after injection) with the silver sulfide technic. The first deposits of mercury were found in the endothelial cells of the interstitial capillaries, then in the glomerular tufts. Finally, the mercury was disclosed within the epithelium of the proximal tubule, whereby the deposits, beginning apically and progressing towards the base of the cell, were in association with the basally situated mitochondria. On the basis of the findings it is postulated, that at least the essential part of the mercury is filtered through the glomerulus and re-absorbed from the filtrate. The studies indicate further, that experimentally the mercuric chloride nephrosis probably develops by direct toxic action of the mercury on the tubular epithelium.
    Notes: Zusammenfassung Die Nieren von Ratten, die mit Sublimat (0,3 mg pro 100 g Körpergewicht) intraperitoneal vergiftet worden waren, wurden in zeitlicher Abstufung (zwischen 5 min und 48 Std nach der Injektion) mit dem Sulfidsilberverfahren untersucht. Die ersten Hg-Ablagerungen finden sich in den Endothelien interstitieller Capillaren, dann im glomerulären Apparat. Schließlich wird das Quecksilber in den Epithelien der Hauptstücke nachgewiesen, wobei die Ablagerung, die apikal beginnt und nach der Zellbasis fortschreitet, im Zusammenhang mit den basal angeordneten Mitochondrien steht. Auf Grund der Befunde wird die Ansicht vertreten, daß zumindest der wesentliche Teil des Quecksilbers über den Glomerulus ausgeschieden und aus dem Filtrat rückresorbiert wird. Die Untersuchungen sind ein weiterer Beweis dafür, daß im Experiment die Sublimatnephrose durch direkte toxische Wirkung des Quecksilbers auf die Tubulusepithelien entsteht.

    Notes: Summary Sixty-seven tumor specimens of epithelial choroid plexus neoplasms obtained by 60 biopsies and 7 autopsies from 52 patients were investigated. Diagnoses of the first operations were choroid plexus papilloma (PP; 32 cases), choroid plexus papilloma with histological atypies (atypical PP; 6 cases), and choroid plexus carcinoma (PC; 14 cases). Carcinoembryonic antigen was expressed by 2 of the 3 biopsies autoptically recognized as metastatic carcinomas and by 2 autopsy cases of PC, while it was absent in all biopsies of true choroid plexus tumors. Tumor cells positive for transthyretin (TTR, prealbumin), S-100 protein (S100), and glial fibrillary acidic protein (GFAP) were detected in 39, 46 and 13, respectively, of the 49 cases of true choroid plexus tumors. Fourth ventricle tumors expressed more S100 (number of positive tumor cells) than lateral ventricle tumors, PP more S100 and TTR than atypical PP/PC. Tumors from patients 20 years of age and older expressed more GFAP and TTR than tumors from younger patients. Of the 30 patients with complete follow-up 19 were alive 2 to 11 years after surgery, including 7 recurrencies. Eleven died from the tumor 4 months to 7 years after surgery. The following histopathologic features (in order of decreasing significance) were correlated with poor prognosis (recurrency or fatal outcome): less than 50% of the tumor cells heavily positive for S100, presence of mitoses, absence of TTR-positive cells, brain invasion by cell nests, absence of marked stromal edema, and presence of necrotic areas. Our results indicate that some histologic features correlate significantly with poor prognosis and that immunohistochemical results correlate with tumor localization, age, and malignancy.

    Description / Table of Contents: Zusammenfassung Auf Grund fermenthistochemischer Untersuchungen an intrakraniellen und intraspinalen Meningiomen wird über die Verteilung folgender Enzyme in diesen Geschwülsten berichtet: saure und alkalische Phosphatase, Arylesterase, Leucinaminopeptidase, Tetrazoliumsalzreduktase (NAD), Succinatdehydrogenase und Cytochromoxydase. Hinsichtlich der Lokalisation der alkalischen Phosphatase lassen sich die untersuchten Tumoren in folgende 3 Gruppen einteilen: 1. Enzymaktivität ausschließlich in den Gefäßwänden, 2. nur das Cytoplasma der Tumorzellen positiv, 3. sowohl Cytoplasma als auch Gefäßwände zeigen Fermentreaktion. Die alkalische Phosphatase, die in den Gefäßwänden lokalisiert ist, besitzt vermutlich eine andere Substratspezifität als die im Cytoplasma. Tetrazoliumsalzreduktase (NAD) ist außer im Cytoplasma auch in den meisten Fällen in Kerneinschlüssen zu erkennen, die vermutlich mit den elektronenmikroskopisch beobachteten Kernwandinvaginationen identisch sind. Abschließend wird gezeigt, daß die Lactatdehydrogenase auch in den Meningiomen in löslicher Form vorliegt und somit ein topochemischer Nachweis dieses Enzyms mit den bisher üblichen Methoden nicht möglich ist.
    Notes: Summary Based on enzyme histochemical findings in intracranial and intraspinal meningiomas, the topic pattern of the following enzymes in these tumours is reported: acid and alkaline phosphatase, arylesterase, leucine aminopeptidase, tetrazolium salt-reductase (NAD), succinic dehydrogenase and cytochrome oxydase. As to the localization of alkaline phosphatase, the examined tumours can be divided into three groups: 1. enzyme activity in the vessel walls exclusively, 2. positive reaction only in the cytoplasm of the tumour cells, 3. enzyme activity both in vessel walls and cytoplasm. Alkaline phosphatase localized in the vessel walls is considered to be of another substrate specifity than that in cytoplasm. Tetrazolium salt-reductase (NAD) is not only to be found in cytoplasm but often also in nuclear inclusions which are probably identical with nuclear membran invaginations as seen with the electron microscope. Lactate dehydrogenase in meningiomas is also present in soluble form; therefore the topochemical identification of this enzyme is not possible by means of the usual methods.

    Notes: Zusammenfassung Durch wiederholte i.v. Injektionen von gelöstem Methylnitrosoharnstoff werden bei 4 Hunden intrazerebrale Geschwülste induziert. Damit ist der Beweis erbracht, dass dieser Stoff nicht nur bei Nagetieren, sondern auch bei grösseren Säugetieren Geschwülste des Zentralnervensystems verursachen kann.

    Notes: Summary Simultaneous peroral application of ethylurea and sodium nitrite to pregnant Sprague-Dawley rats, on the 9th and 10th days of gestation, causes embryotoxic and/or teratogenic effects. Each substance alone does not afflict the fetuses, whereas the combined addition to the food permits the formation of ethyl nitroso-urea in the digestive tract. The latter readily passes the placenta and develops the teratogenic effect. It is to be considered that teratogenic substances can occur from food constituents in the human organism also.
