Abstract: AIM: To investigate any protective effect of early propranolol administration in the development of portal hypertensive gastropathy in cirrhotic rats.METHODS: For the development of liver cirrhosis and portal hypertensive gastropathy, 60 rats underwent ligation of the left adrenal vein and complete devascularization of the left renal vein, followed by phenobarbital and carbon tetrachloride (CCl4) administration. After two weeks of CCl4 administration, the rats were randomly separated into two groups. In group A, propranolol was continuously administered intragastrically throughout the study, whereas in group B normal saline (placebo) was administered instead. Hemodynamic studies and vascular morphometric analysis of gastric sections were performed after complete induction of cirrhosis.RESULTS: Vascular morphometric studies showed higher numbers of vessels in all mucosal layers in the control group. Statistical analysis revealed a significantly higher total vascular surface in the control group compared to the propranolol group, but with no statistically significant difference between the mean vascular surfaces between the groups. Our study clearly shows that the increased mucosal blood flow is manifested by a marked increase of vessel count.CONCLUSION: Early propranolol’s administration in portal hypertensive cirrhotic rats seems to prevent intense gastric vascular congestion that characterizes portal hypertensive gastropathy.

Giving Voice To Employees And Spreading Information Within The Firm: The Manner Matters
Enzo Valentini
Journal of Knowledge Management, Economics and Information Technology , 2012,
Abstract: The aim of this paper is to verify empirically whether giving voice to employees and spreading information within the firm increase job satisfaction, while thoroughly analyzing if different means imply different consequences. The analysis was carried out using a British data set: ``Changing Employment Relationship, Employment Contracts and the Future of Work Survey (Working in Britain 2000)’’. An ordered probit model was used for estimation. The results con rm the effects of individual features on job satisfaction, as highlighted inprevious studies. The analysis shows that job satisfaction can be enhanced by spreading information within the organization and by giving voice to employees, but the management must choose communication strategies perceived as reliable by the employees.

Ern hrungsteams - eine interprofessionelle Herausforderung
Valentini L
Journal für Ern?hrungsmedizin , 2000,
Abstract: Ern hrungsteams sind Einrichtungen in Spit lern oder Pflegeheimen, deren Schwerpunkt der fachgerechte Einsatz von enteralen und parenteralen Ern hrungstherapien ist. W hrend Ern hrungsteams in Gro britannien und den Vereinigten Staaten gut etabliert sind, stecken sie in sterreich noch in den Kinderschuhen. Dennoch, einige wenige wurden in den 90ern in sterreich gegründet, bew hrten sich und spielen nun eine Vorbildrolle für andere Krankenh user. Unterschiede im Gesundheitssystem und bei den Personalressourcen bedingen, da das amerikanische bzw. britische Konzept des Ern hrungsteams nur begrenzt in sterreich anwendbar ist. Im vorliegenden Artikel werden mit Rücksicht auf sterreichische Verh ltnisse die Aufgaben und Ziele eines Ern hrungsteams sowie die Rollenverteilung der einzelnen Berufsgruppen vorgestellt.
