Morphometry was performed on the left ventricular posterior papillary muscles of seven Wistar rats. The volume densities of myocardial cells, interstitial space, myocardial nuclei, sarcoplasm, mitochondria, myofibrils, ground substance and T tubules, and the surface densities of myocardial cells, mitochondrial membranes and T tubules, were calculated.(More)

Male Wistar rats were treated with high cortisol doses for 1 week. The dose administered daily was 15 mg per animal in group 1 (7 animals) and 30 mg in group 2 (7 animals). 7 rats served as control group. After cortisol treatment the body weights decreased due to skeletal muscle catabolism and the heart weights increased. Morphometric analysis of the left(More)
The non-Langerhans cell histiocytosis (LCH) juvenile xanthogranulomatosis (JXG) is usually a benign disease limited to the skin. Only a few cases of systemic disease with at least two affected organs and lethal outcomes have been reported to date. Treatment is controversial and no standard protocol is available. We report the rare case of a 22-month-old boy(More)
Der Wilms-Tumor, der häufigste maligne Nierentumor im Kindesalter, gilt als das Paradebeispiel einer heilbaren bösartigen Erkrankung. Die Behandlung dieses Tumors erfolgt heute weltweit in zwei großen Studiengruppen. In Nordamerika handelt es sich um die National Wilms Tumor Study Group (NWTSG) und in Europa um die Wilms Tumour Study Group der SIOP (Society(More)
Im Zeitraum vom 1.1. 1987 bis zum 1.7. 1988 untersuchten wir insgesamt 197 Patientinnen mit der Einweisungsdiagnose Plazentainsuffizienz. Das Ger/it, das uns zur Verfiigung steht, ist der ACUSON 128, ein Duplex-System mit einem 3,5 MHz Sector-Scan und integriertem Doppler. Untersucht wurde der Flow in der fetalen Aorta abdominalis, wobei die cut-off-line(More)
A method for radiological presentation of the left ventricular conduction system was tested for in-vivo tolerability. In-vivo tolerability could be demonstrated clinically; however, we should emphasize that hypertonic X-ray contrast dyes may cause morphological changes of unknown significance in the micro- and ultrastructures of the specialized musculature.(More)
The in-vivo tolerability of an in vitro in cow, calf and sheep hearts developed method for radiologic visualization of the left ventricular conduction system is tested in four animal experiments. The clinical in-vivo tolerability could be demonstrated on principle; however, it is to accent that hypertonic X-ray contrast dyes may be the cause of(More)
