Helicobacter pylori infection in various groups of patients studied, estimated by 14C-urea breath test.

The aim of this study was the detection of helicobacter pylori (HP) infection and estimation of the clinical validity and the accuracy of the 14C-urea breath test in the groups of patients studied. A total of 248 patients with gastric diseases were examined. There were 38 patients with gastric ulcer, 41 with duodenal ulcer, 43 with gastroduodenitis erosiva, 26 with hiatus hernia, 36 with gastric carcinoma and 64 patients with gastritis.

Possible role of the scintigraphic estimation of the relative liver perfusion in the diagnosis and therapy of liver carcinomas.

Background: The aim of the study is evaluation of the possible role of the scintigraphic estimation of the relative liver perfusion in diagnosis and the choice of treatment of liver carcinomas.

Material And Methods: Hepatic perfusion index was obtained by dynamic scintigraphy in 126 patients.

Results: In the control group values did not differ from the value in the patients with benign tumors (p > 0.
