    Notes: Summary We present our clinical experience and the results of surgical management with 25 cavernomas of the CNS, treated in our hospital in the last 10 years. The location of the lesion assessed by clinical and CT scan examinations, proved to be the most significative factor determining the prognosis of cavernomas of the CNS, after surgical removal. The symptoms started in most of the cases in the third decade of life. 19 cases were located in the cerebral hemispheres and produced three well defined clinical syndromes: 1) Irritative syndrome (seizures) present in 70% of the cases. 2) Space-occupying lesion syndrome (20%) and 3) haemorrhagic syndrome (10%). The remaining six cases were located within the basal ganglia, brainstem, pineal region, cerebellum and spinal cord, showing a progressive course. CT scan studies were performed on 24 cases. The characteristic image of a cavernoma is represented by a moderately hyperdense nodule with discreet contrast uptake. Calcification was observed in and around the lesions in 33% of the cases. Perilesional hypodensities suggestive of brain tissue atrophy were noted in 22% of the CT scans. On the other hand, 12% of cerebral hemisphere cavernomas showed atypical CT scan images that suggested an erroneous diagnosis of cystic gliomas. Radical surgical removal was performed in all cases. The postoperative results varied according to the location of the lesions. Complete recovery was obtained with cerebral hemisphere cavernomas presenting with a progressive history suggesting tumour or a haemorrhagic syndrome. 85% of the cases presenting with seizures, were symptom-free and taking no anticonvulsants 1 year after surgery. In deeply placed cavernomas (basal ganglia and brainstem) the surgical results were poor. In the latter cases surgery has to be carefully evaluated when a mode of treatment is to be considered in patients whose CT scan data strongly suggest a diagnosis of cavernoma.

    Description / Table of Contents: Zusammenfassung Die Gallensalze setzen den enterohepatischen Kreislauf fort. Die Cholsäure (Carboxylic14C), nach ihrer intravenösen Injektion verteilt sich im Niveau des Portalkreislaufes, Dünndarmwand, Inhalt des Dünndarms, Leber und Stuhl, welches als gutes Zeichen der Absorbierungskapazität der Epithelzellen des Darms betrachtet werden kann. In Ratten, bei denen eine totale Dünndarmresektion (60–80 cm) durchgeführt wurde, beobachtete man nach 7 Tagen eine bedeutende Verminderung der Absorbierung der Cholsäure. Trotzdem ist 30 Tage nach der Operation das Gewicht der Tiere sowie die radioaktiven Befunde gleich den Tieren der Kontrollgruppe, und zwar im Blut der Portalvene und der V. Cava, sowie im Darminhalt, Leber und Stuhl. In dieser Studie wurde eine Erhöhung der Absorbierungskapazität der Epithelzellen des Dünndarms beobachtet.
    Notes: Summary Bile salts undergo an enterohepatic circulation. The relative distribution of labelled cholic acid in portal blood, enterocytes, intestinal contents and feces, following intravenous injection of (carboxylic-14C) cholic acid, can be considered as an indication of the absorptive capacity of the epithelium cells. Seven days after a massive small intestinal resection (60–80 cm), the animal weight and the bile salt absorption were significantly decreased. Nevertheless, thirty days after the operation, weight and radioactivities reached the values found in the controls: in portal and cava blood, liver, intestinal contents and feces. An increase of the absorptive capacity of the intestinal epithelial cells was also observed.

    Notes: Abstract An analysis of the variation in the number and location of rDNA genes has been carried out in two populations of brown trout (Salmo trutta) from Poland by using Ag and CMA3-staining, and rDNA in situ hybridisation. We observed an interindividual variation in arm number with NF = 100, 101, and 102. This variation was connected with the size polymorphism of the short (NOR-bearing) arm of the chromosome pair 11. The population studied showed a multichromosomal distribution of active NORs. Atypical Ag-NORs consisted of rDNA genes, as evidenced by rDNA-ISH. In addition to individuals with standard NORs, specimens with extra NORs as well as others with only one active NOR and single interphase nucleolus were observed.
