The diaminobenzidine (DAB) method was adapted for the microphotometric determination of cytochrome c oxidase (cyt ox) in the rat hippocampus. The qualitative and quantitative investigations at the light microscopic level showed that acetone and cytochrome c pretreatment of cryostat sections resulted in a significant increase of demonstrable cyt ox(More)
Clinical experience gives evidence of the increasing importance of chronic-abscess-forming peritonitis with a general physical impairment in spite of a well-controlled abdominal situation. The number of unsolved problems led us to develop a standardized and reproducible experimental animal model, using Wistar rats. We induced peritonitis by intraperitoneal(More)
We applied cytochemical procedures to demonstrate the presence of acid and alkaline phosphatase in the visceral yolk-sac endoderm of rats using frozen, aldehyde-fixed tissue with cerium as the capture agent. This procedure allowed more detailed topochemical localization than was possible using unfrozen tissue or with lead as the capture agent. Acid(More)

Acute peritonitis is still associated with a high mortality rate. Bacterial toxins are rapidly cleared from the peritoneal cavity and may induce general sepsis. The hepatic sinusoidal cells are part of the primary defence against these toxins. The object of this study was to examine ultrastructural alterations of human sinusoidal liver cells from patients(More)
Between the years 1985 and 1989 11 patients with iatrogenic esophageal perforation were treated at the Department of Surgery at the University of Würzburg. 5 perforations were diagnosed within 24 hours, the others after 1 to 5 days. All patients received a non resective surgical treatment, consisting of excision of the perforated area, primary closure in(More)
