We have undertaken esophagoscopy 1/2 to 17 1/2 years after surgery in 20 patients with a total gastrectomy and an esophago-jejunal anastomosis. In 5 cases we found a complete columnar lining of the distal esophagus (Barrett-esophagus). 2 other cases showed a multilocular columnar epithelium. One case with a Barrett-esophagus had endoscopy before surgery,(More)
Stem cell therapy seems promising in reducing deficits after focal cerebral ischemia. As stroke may result from intracerebral hemorrhage (ICH) in up to 20% we investigated whether human processed lipoaspirate mesenchymal stem cells (PLA-MSC) influence the functional outcome, migration behavior and the activation of endogenous progenitor cells. Experimental(More)
A case report is given on a male patient who was 52 years old when he died. 9 years ago a nephrectomy was performed because of a densely-packed mesenchymal tumor of the adipose tissue of the pelvis renalis. 7 years after the surgical intervention he suffered from several hypoglycemic crises. An operation was performed, and 2 large tumor nodes were removed(More)
Coronary thrombosis was induced in 14 miniature pigs by means of direct current. The induction electrode was introduced via the common carotid artery into the coronary artery. The intensity of current (1 mA) and the duration of current flow (60 min) were kept constant in all the experimental animals. 6 miniature pigs survived the period of observation (48(More)
By means of electric induction without opening the chest in 23 dogs coronary thromboses were produced with the aid of a standardized method based on a test model of Salazar (1961). The morphological results are reported. 13 of the dogs showed coronary thromboses. At the same time in 12 animals a myocardial infarction could be registered. Altogether, we(More)

Results obtained from autopsy are parameters of importance to efficacy of diagnosis and therapy. To enable better overseeability of higher numbers of cases, the necessary congruence between clinical and postmortem diagnoses should be consistently settled on the basis of identical criteria used by clinicians and pathologists. Aspects relating to the problem(More)
Since 1972 6 patients (4 males and 2 females) at the age from 18 to 44 years with myocardial infarctions could be observed whose coronary system in the subsequent coronarographic examinations proved to be unconspicuous. The diagnosis of the infarction was anamnestically, laboratory-chemically, electrocardiographically and partly scintigraphically(More)
