Anatomical studies suggested a presinusoidal or an intrasinusoidal confluence in the first, second or even final third of the sinusoids. The objective of this investigation was to study the problem with functional biochemical techniques. Rat livers were perfused through the hepatic artery and simultaneously either in the orthograde direction from the portal vein to the hepatic vein or in the retrograde direction from the hepatic vein to the portal vein. Arterial how was linearly dependent on arterial pressure between 70 cm H2O and 120 cm H2O at a constant portal or hepatovenous pressure of 18 cm H2O. An arterial pressure of 100 cm H2O was required for the maintenance of a homogeneous orthograde perfusion of the whole parenchyma and of a physiologic ratio of arterial to portal how of about 1:3. Glucagon was infused either through the artery or the portal vein and hepatic vein, respectively, to a submaximally effective ''calculated'' sinusoidal concentration after mixing of 0.1 nmol/L. During orthograde perfusions, arterial and portal glucagon caused the same increases in glucose output. Yet during retrograde perfusions, hepatovenous glucagon elicited metabolic alterations equal to those in orthograde perfusions, whereas arterial glucagon effected changes strongly reduced to between 10\% and 50\%. Arterially infused trypan blue was distributed homogeneously in the parenchyma during orthograde perfusions, whereas it reached clearly smaller areas of parenchyma during retrograde perfusions. Finally, arterially applied acridine orange was taken up by all periportal hepatocytes in the proximal half of the acinus during orthograde perfusions but only by a much smaller portion of periportal cells in the proximal third of the acinus during retrograde perfusions. These findings suggest that in rat liver, the hepatic artery and the portal vein mix before and within the first third of the sinusoids, rather than in the middle or even last third.}, language = {en} } @misc{NeuschaeferRubeDeVriesHaeneckeetal.1994, author = {Neusch{\"a}fer-Rube, Frank and DeVries, Christa and H{\"a}necke, Kristina and Jungermann, Kurt and P{\"u}schel, Gerhard Paul}, title = {Molecular cloning and expression of a prostaglandin E₂ receptor of the EP₃ϐ subtype from rat hepatocytes}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-45830}, year = {1994}, abstract = {Rat hepatocytes have previously been reported to possess prostaglandin E₂ receptors of the EP₃-type (EP₃-receptors) that inhibit glucagonstimulated glycogenolysis by decreasing cAMP. Here, the isolation of a functional EP₃ϐ receptor cDNA clone from a rat hepatocyte cDNA library is reported. This clone can be translated into a 362-amino-acid protein, that displays over 95\% homology to the EP₃ϐ receptor from mouse mastocytoma. The amino- and carboxy-terminal region of the protein are least conserved. Transiently transfected HEK 293 cells expressed a single binding site for PGE₂ with an apparent Kd of 15 nM. PGE₂ > PGF₂α > PGD₂ competed for [³H]PGE₂ binding sites as did the EP₃ receptor agonists M\&B 28767 = sulprostone > misoprostol but not the EP₁ receptor antagonist SC 19220. In stably transfected CHO cells M\&B 28767 > sulprostone = PGE₂ > misoprostol > PGF₂α inhibited the forskolin-elicited cAMP formation. Thus, the characteristics of the EP₃ϐ receptor of rat hepatocytes closely resemble those of the EP₃ϐ receptor of mouse mastocytoma.}, language = {en} } @article{KrollHelle1994, author = {Kroll, J{\"u}rgen and Helle, N.}, title = {Mechanochemischer Abbau von Proteinen : ESR - spektroskopische Untersuchungen}, year = {1994}, language = {de} } @article{KrollRawelKroecketal.1994, author = {Kroll, J{\"u}rgen and Rawel, Harshadrai Manilal and Kr{\"o}ck, Regina and Proll, J{\"u}rgen and Schnaak, W.}, title = {Interactions of Isothiocyanates with egg white proteins}, year = {1994}, language = {en} } @misc{PueschelJungermann1994, author = {P{\"u}schel, Gerhard Paul and Jungermann, Kurt}, title = {Integration of function in the hepatic acinus : intercellular communication in neural and humoral control of liver metabolism}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-51279}, year = {1994}, abstract = {Content: Architecture of the liver acinus Functional zonation of the liver acinus Topological organization of metabollc regulation in the acinus Topological organization of defense and organ structure regulation in the acinus}, language = {de} } @misc{PueschelChrist1994, author = {P{\"u}schel, Gerhard Paul and Christ, Bruno}, title = {Inhibition by PGE₂ of glucagon-induced increase in phosphoenolpyruvate carboxykinase mRNA and acceleration of mRNA degradation in cultured rat hepatocytes}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-45792}, year = {1994}, abstract = {In cultured rat hepatocytes the key gluconeogenic enzyme phosphoenolpyruvate carboxykinase (PCK) is known to be induced by glucagon via an elevation of cAMP. Prostaglandin E₂ has been shown to antagonize the glucagon-activated cAMP formation, glycogen phosphorylase activity and glucose output in hepatocytes. It was the purpose of the current investigation to study the potential of PGE₂ to inhibit the glucagon-induced expression of PCK on the level of mRNA and enzyme activity. PCK mRNA and enzyme activity were increased by 0.1 nM glucagon to a maximum after 2 h and 4 h, respectively. This increase was completely inhibited if 10 μM PGE2 was added concomitantly with glucagon. This inhibition by PGE₂ of glucagon-induced PCK activity was abolished by pertussis toxin treatment. When added at the maximum of PCK mRNA at 2 h, PGE₂ accelerated the decay of mRNA and reduced enzyme activity. This effect was not reversed by pertussis toxin treatment. Since in liver PGE₂ is derived from Kupffer cells, which play a key role in the local inflammatory response, the present data imply that during inflammation PGE₂ may reduce the hepatic gluconeogenic capacity via a Gᵢ-linked signal chain.}, language = {en} } @article{StoofKruseAnger1994, author = {Stoof, Gisela and Kruse, Hans-Peter and Anger, Horst}, title = {Hydrothermische Behandlung von St{\"a}rke in Gegenwart von -Amylase}, year = {1994}, language = {de} } @article{HusbandWildeClarketal.1994, author = {Husband, Fiona and Wilde, Peter J. and Clark, David C. and Rawel, Harshadrai Manilal and Muschiolik, Gerald}, title = {Foaming properties of modified faba bean protein isolates}, year = {1994}, language = {en} } @article{RawelMuschiolik1994, author = {Rawel, Harshadrai Manilal and Muschiolik, Gerald}, title = {Effect of structural changes on foaming properties of soy proteins}, year = {1994}, language = {en} } @article{KrollNoackRaweletal.1994, author = {Kroll, J{\"u}rgen and Noack, Jutta and Rawel, Harshadrai Manilal and Kr{\"o}ck, Regina and Proll, J{\"u}rgen}, title = {Chemical reactions of benzyl isothio cyanate with egg-white protein fractions}, year = {1994}, language = {en} } @article{KruseStoofRubbertetal.1994, author = {Kruse, Hans-Peter and Stoof, Gisela and Rubbert, Helga and Anger, Horst}, title = {Characterisation of fat replacers}, year = {1994}, language = {en} } @article{StarkWalzel1994, author = {Stark, Claudia and Walzel, Erwin}, title = {Alterseinfluß auf Bleiakkumulation und -elimination im Rattenknochen}, year = {1994}, language = {de} } @article{AngerWalzelKahrmann1994, author = {Anger, Horst and Walzel, Erwin and Kahrmann, Bettina}, title = {About the absorption of oligogalacturonates from the caecum of rats}, year = {1994}, language = {en} }
