    Notes: Summary Chemically induced (autochthonous) tumors in the rodent are thought to be the best models at hand to obtain results transferable to the clinical situation. Four different autochthonous tumor models: 1,2-dimethylhydrazine, N-methylnitrosourea (MNU), N-methyl-N-nitro-nitrosoguanidine (MNNG), and N-nitroso-acetoxymethyl-methylamine (AMMN) which are used worldwide for etiological and therapy studies of colon cancer are compared for tumor biology and clinical relevance. The four tumor models of colon carcinoma described in the rat are different in growth, invasion, and metastases. The choice of the selected tumor model for experimental investigations of colon cancer should depend on the clinical question.

    Notes: Abstract The temperature dependence of the magnetic susceptibility of Uranocene ((C8H8)2U(IV)) between 1.25 and 298 K has been measured for the first time and the results correlated with a systematic study of the crystal field splitting. Independent estimates of the three crystal field parameters B 2 0 , B 4 0 and B 6 0 were obtained by adopting the purely electrostatic approach, the angularoverlap-model and the MHW-MO-method. Subsequently the crystal field splitting pattern was calculated by a simultaneous diagonalisation of the complete f 2-matrix. Assuming rigorous D 8h-crystal field symmetry, a crystal field splitting pattern involving a singlet ground state and a low lying first excited doublet state (ΔE=17cm−1, ¦ΔJ2¦ = 1) gives the best agreement with both the MO-results and the experimental findings. The experimental l/χ-vs-T-curve is reproduced to a good approximation by a calculation employing the optimal parameter set: B 2 0 = −5610, B 4 0 = −1426,B 6 0 = −730cm−1. A crystal field of slightly lowered symmetry having a significantly split doublet ground state and hence positive B 2 0 -values cannot be completely ruled out.

    Description / Table of Contents: Zusammenfassung Die Symptome einer Hämobilie sind in der Trias von Sandblom zusammengefaßt: Blutung aus dem G.I.-Trakt, Ikterus, abdominelle Schmerzen. Die Blutung nach Trauma wird durch ein Arteriogramm, evtl. durch ein CT nachgewiesen. Die Hämobilie nach Leberpunktion ist schwach und zeigt sich durch einen cholestatischen Ikterus. Die Diagnostik erfolgt über eine Cholangiografie (retrograd transpapillär oder percutan transhepatisch). Die Behandlung der Blutung erfolgt durch arterielle Embolisation oder arterielle Ligatur (interparenchymatös, Lobärarterie, A. hepatica propria). Bei Verschluß-Ikterus wird endoskopisch canaliculär desobliteriert. Die Hämobilie nach Drainage schwindet meist nach Entfernung des T-Drains.
    Notes: Summary Hemobilia presents with the triad of biliary colic, obstructive jaundice and occult or gross intestinal bleeding. Bleeding after trauma is diagnosed by arteriography. Hemobilia following liver biopsy is manifested by obstructive jaundice and is diagnosed by transhepatic or retrograde endoscopic cholangiography. The bleeding should be treated by transarterial embolization, direct ligation of the bleeding point in the liver, or proximal ligation of an upstream branch of the hepatic artery. Obstructive jaundice is treated by retrograde removal of the canalicular obstruction. Hemobilia following T tube implantation vanishes in most cases after removal of the tube. Liver resection is required only in rare cases. Of our nine patients seven were saved by this regimen. Two died postoperatively, due to the extent of the liver trauma and associated injury to other organs.

    Description / Table of Contents: The Electronic Structure of Highly Symmetrical Compounds of the Lanthanides and Actinides. X. The Crystal Field Splitting Pattern of Cs2NaPrIIICl6 in the Low Energetic RegionBy means of the techniques of the electronic Raman effect, absorption and emission spectroscopy the low energetic crystal field splitting pattern of Cs2NaPrCl6 could be determined. Using the parameter set: F2 = 317.3, F4 = 54.4, F6 = 6.35, ζ4f = 762.8, B°4 = 271.9 and B°6 = 16.8 cm-1 a good agreement between observed and calculated signals has been achieved.
