    Notes: Summary: Confocal scanning laser microscopy (CSLM) has the potential to provide new insights into matrix deposition in renal pathology. For example laser stimulated light emission from Kimmelstiel Wilson (KW) nodules emphasizes a difference between peripheral and central nodule contents, an observation matching immunoperoxidase studies, which fails to demonstrate high density of renal matrix proteins in the core.

    Notes: Zusammenfassung An einem weichgemachten Polyvinylchlorid wurden bei Dehnbeanspruchung stabförmiger Proben die Spannungsrelaxation bei verschiedenen Dehnungen und die Deformationsretardation bei verschiedenen Spannungen untersucht. Die Temperatur wurde so variiert, daß das Materialverhalten im gesamten Bereich vom glasig-amorphen bis zum quasi-gummielastischen Zustand erfaßt wurde. Aus den Ergebnissen der beiden Versuchsarten wird geschlossen, daß außerhalb des linearen Beanspruchungsbereiches bei allen Temperaturen die Zeit- und die Deformationsabhängigkeit der Spannung getrennt werden können, während eine Trennung der Zeit- und der Spannungsabhängigkeit der Dehnung nicht möglich ist.

    Notes: Die Astrozytome hohen Malignitätsgrades (Grad III, IV) sind mit etwa 30% die häufigsten und zugleich aggressivsten Hirntumoren gliösen Ursprungs und führen unbehandelt innerhalb weniger Wochen zum Tode. Neben der primär einzusetzenden Operation ist der Stellenwert der postoperativen perkutanen Strahlentherapie in der Behandlung der malignen Gliome unbestritten. Derzeit gibt es keinen gesicherten Hinweis, daß eine Chemotherapie Operation und Strahlentherapie ersetzen kann, so daß die malignen Gliome wegen ihres aggressiven Wachstums und der damit verbundenen schlechten Prognose unverändert eine Herausforderung an den Radioonkologen stellen.

    Notes: Leukämien sind klonale, neoplastische Proliferationen von Zellen der hämatopoetischen Differenzierungskaskade. Fast alle leukämischen Zellen sind ausgesprochen strahlenempfindlich. Bei diesen systemischen Neoplasien kann daher die Strahlentherapie in dreierlei Hinsicht zum integralen Bestandteil multimodaler Therapiekonzepte werden: im Rahmen der Primärtherapie, als myoablative Therapie zur Konditionierung z.B. vor Knochenmarktransplantationen oder zur Palliation bei Leukämie-assoziierten Problemen.

    Description / Table of Contents: Summary The reaction of satellite cells after the experimental infection with a neurotropic virus shows an enlargement of the nuclei of the satellite cells, an approach of the satellite cells to their ganglion cells, and a multiplication of the oligodendroglia. This reaction takes the same course in both chicks and chickens. Despite the possibility of re-isolating the virus from the brain, and the existence of a preencephalitic activation of the vessel wall, the reaction fails to show up when weak virulent strains of viruses are used. A highly virulent virus provoked a clear satellitosis in surviving animals only. However, no reaction could be observed in dead animals. The cytodynamic behavior of the satellite cells is quite similar after the experimental withdrawal of the nutrition, and after artificial coccidiosis. A stress induced by shaking until exhaustion (of the test animals) is just followed by lessening the distance, whereas no functionalswelling of nuclei and the multiplication of glial cells take place. The maturing of the satellite cell, dependent upon the age, was distinguished from these reactive alterations. It occurs mainly between the fourth and seventh week of life, and is characterized by the decrease in volume, by lessening the distance between satellite and ganglion cells, and by an augmentation of the glial index.
    Notes: Zusammenfassung Die Reaktion der Satellitenzellen besteht bei experimenteller Infektion mit einem neurotropen Virus in einer Vergrößerung der Satellitenzellkerne, einer Annäherung der Satellitenzellen an ihre Ganglienzellen und in einer Vermehrung der Oligodendroglia. Diese Reaktion verläuft be Külen und Hennen gleichartig. Sie bleibt bei Verwendung schwach virulenter Virusstämme aus, obwohl das Virus aus dem Gehirn rückisolier werden konnte und eine präencephalitische Gefäßwandaktivierung vorlag. Ein hochvirulentes Virus provozierte eine deutliche Satellitose nur bei den überlebenden Tieren. Bei den gestorbenen ließ sich dagegen keine Reaktion objektivieren. Das cytodynamische Verhalten der Satellitenzellen ist ähnlich nach experimentellem Nahrungsentzug und künstlicher Coccidiose. Bei einem bis zur Erschöpfung einwirkenden Schüttelstress erfolgt nur die Distanzverringerung, während die funktionelle Kernschwellung und die Vermehrung der Ganglienzellen unterbleiben. Von diesen reaktiven Veränderungen wurde die altersabhängige Ausreifung der Satellitenzelle abgegrentzt. Sie vollzieht sich hauptsächlich zwischen der 4. und 7. Lebenswoche und besteht in Volumenverkleinerung, Verringerung der Distanz zwischen Satelliten- und Ganglienzellen sowie in einer Vergrößerung des Gliaindex.

    Notes: Summary The aim of this study was to evaluate whether intra-operative ultrasound (=IOUS) is a suitable tool to detect residual tumour tissue after gross total resection in supratentorial gliomas. During a period of 18 months 45 patients with supratentorial gliomas (38 high-grade and 9 low-grade, according to the WHO-grading system [42]) were operated on. A series of 78 biopsies was taken from the resection cavity under continuous sonographic control at the end of surgery. Gross total tumour resection was intended in 34 patients (=76%). The biopsy specimens were matched with the sonographic features at each biopsy site. The sonographic appearance of the resection margins were classified into 2 groups: (1) Irregular hyperechoic areas extending from the cavity into the iso-echogenic brain tissue and (2) a dense small (≤3 mm in diameter) rather regular hyperechoic rim surrounding the resection cavity. 47 out of 53 biopsies taken from hyperechoic areas (group 1) (36 high-grade/11 low-grade) revealed solid tumour tissue (=89%). 34 (=72%) of these 47 areas were microscopically assessed as inconspicuous by the surgeon. 6 samples (4 high-grade/2 low-grade) contained tumour infiltration zone. 25 biopsies (23 high-grade/2 low-grade) taken from the hyperechoic rim [group 2] were diagnosed as follows: Normal brain tissue in 11, tumour infiltration zone in 8 and solid tumour tissue in 6 cases. Of 34 cases with “gross total removal” according to the surgeon's assessement 25 showed sonographic signs of residual tumour tissue, which was confirmed histologically as solid tumour tissue in 22 of these cases. It is concluded, that IOUS following resection of supratentorial gliomas can detect residual tumour tissue with high specificity and thus improve gross total resection. However, a thin hyperechoic rim surrounding the resection cavity (less than 3 mm in diameter) is a non-specific finding, which can mask thin residual tumour layers and therefore needs further evaluation of its nature.
