Aus dem Inhalt: Ende der siebziger Jahre kam aus Krakau eine sensationelle Nachricht: Der lange verlorengeglaubte Nachlaß von August Varnhagen von Ense, in dem sich auch die Briefe seiner Frau Rahel, geborene Levin, befinden, wurde in der Jagiellonen-Bibliothek wiedergefunden. Dadurch ergab sich für alle Interessierten - Germanisten, Judaisten, Historiker - erneut die Möglichkeit, in authentische Zeugnisse der deutsch-jüdischen Kultur des 19. Jahrhunderts Einblick zu nehmen. Sowohl die Varnhagen-Forschung als auch das damit zusammenhängende Interesse an den jüdischen Frauen der deutschen Romantik hat dadurch neue Impulse erhalten. Dies ist ein erfreuliches Beispiel fruchtbarer kultureller Wechselbeziehungen im Dreieck zwischen Deutschen, Polen und Juden. Aber es gibt auch anderes: Wenn man heute durch Polen fährt, kann man auf den Mauern die in deutscher Sprache (!) gepinselten Parolen »Juden raus!« lesen. Damit wären wir in medias res, denn die Geschichte der drei so eng miteinander verbundenen Völker ist gekennzeichnet durch wechselvolle, meist konfliktreiche Koexistenz, die aber trotzdem für alle Beteiligten kulturell sehr bereichernd sein kann.
The use of preformed polymers for the preparation of Langmuir-Blodgett (LB) multilayers is reviewed. Principles for polymer self-organization are outlined and the appropriate molecular designs are discussed. Recent developments in the different classes of polymers for LB multilayers are presented, and their outstanding properties highlighted.
1) During orthograde perfusion of rat liver human anaphylatoxin C3a caused an increase in glucose and lactate output and reduction of flow. These effects could be enhanced nearly twofold by co-infusion of the carboxypeptidase inhibitor MERGETPA, which reduced inactivation of C3a to C3adesArg. 2) During retrograde perfusion C3a caused a two- to threefold larger increase in glucose and lactate output and reduction of flow than in orthograde perfusions. These actions tended to be slightly enhanced by MERGETPA. 3) The elimination of C3a plus C3adesArg immunoreactivity during a single liver passage was around 67%, irrespective of the perfusion direction and the presence of the carboxypeptidase inhibitor MERGETPA; however, less C3adesArg and more intact C3a appeared in the perfusate in the presence of MERGETPA in orthograde and retrogade perfusions It is concluded that rat liver inactivated human anaphylatoxin C3a by conversion to C3adesArg and moreover eliminated it by an additional process. The inactivation to C3adesArg seemed to be located predominantly in the proximal periportal region of the liver sinusoid, since C3a was less effective in orthograde perfusions, when C3a first passed the proximal periportal region before reaching the predominant mass of parenchyma as its site of action, than in retrograde perfusions, when it first passed the perivenous area. These data may be evidence for a periportal scavenger mechanism, by which the liver protects itself from systemically released mediators of inflammation that interfere with the local regulation of liver metabolism and hemodynamics.
Rat serum, in which the complement sytem had been activated by incubation with zymosan, increased the glucose and lactate output, and reduced and redistributed the flow in isolated perfused rat liver clearly more than the control serum. Heat inactivation of the rat serum prior to zymosan incubation abolished this difference. Metabolic and hemodynamic alterations caused by the activated serum were dose dependent. They were almost completely inhibited by the cyclooxygenase inhibitor indomethacin and by the thromboxane antagonist 4-[2-(4-chlorobenzenesulfonamide)-ethyl]-benzene-acetica cid (BM 13505), but clearly less efficiently by the 5’-lipoxygenase inhibitor nordihydroguaiaretic acid and the leukotriene antagonist N-{3-[3-(4-acetyl-3-hydroxy-2-propyl-phenoxy)-propoxy]-4-chlorine-6-methyl-phenyl}-1H-tetrazole-5-carboxamide sodium salt (CGP 35949 B). Control serum and to a much larger extent complement-activated serum, caused an overflow of thromboxane B₂ and prostaglandin F₂α into the hepatic vein. It is concluded that the activated complement system of rat serum can influence liver metabolism and hemodynamics via release from nonparenchymal liver cells of thromboxane and prostaglandins, the latter of which can in turn act on the parenchymal cells.
