Infections with enterohepatic Helicobacter species (EHS) can change the results of animal experiments. However, there is little information about the prevalence of EHS in noncommercial animal facilities. The aim of this study was to investigate the prevalence and the spread of EHS in specific-pathogen-free (SPF) mice. Fecal samples of 40 mouse lines were(More)
The middle cerebral artery (MCA) of cats was occluded permanently for 24h to study the influence of arterial hypertension during the early phase of focal ischemia upon the development of endema and changes of the blood-brain barrier (BBB). In normotensive animals MCA occlusion results in a hemispheric weight increase of about 8% and marked water and(More)
High local recurrence rates within the previous tumor bed or at the peritoneum remain an unsolved problem after surgical resection of malignant gastrointestinal tumors such as gastric, colorectal or pancreatic carcinoma. Currently, there are no standardized treatment protocols available for the prevention or treatment of peritoneal carcinomatosis. In a(More)
Twenty-four h after permanent occlusion of the middle cerebral artery (MCA) in the cat, the hemispheric swelling due to edema is markedly reduced under treatment with large doses of dexamethasone than is the case with the untreated group. The increase of regional water and sodium content in the MCA territory is less in the dexamethasone treated group,(More)
