[Echography of the upper abdominal vessels (author's transl)].

The newer generation of real-time ultrasonic equipment with its high resolution capacity permits not only visualization of the large abdominal vessels like the aorta and inferior vena cava, but in addition the tracing smaller visceral branches. The celiac trunk with its branches, the common hepatic artery and the splenic artery, the superior mesenteric and the two renal arteries can be visualized in 60-80% of all echographically examined patients. Consequently the new possibilities of abdominal echography with regard to assessment of the variations of vessels from the norm and intravascular processes such as thromboses are opened up. Changes in the courses of vessels permit conclusions on the seat and direction of growth of tumors.

[The value of determining occult blood in clinical practice].

The haemoccult-test is recommended above all for the early recognition of the colon carcinoma. The stool of 183 relatively unselected patients was examined for occult blood by means of this test in order to control its importance for clinical practice. In 37 patients (20%) the test was positive at least once. Apart from origins of haemorrhage in the lower gastrointestinal tract in the upper one haemorrhages were found in epistaxis, hiatal hernia, gastric and duodenal ulcers [7] and carcinomas of the stomach, the latter in an already advanced stages. In one female patient with carcinoma of the stomach the test was falsely positive. The negative test does not exclude a tumor, in a positive result should also be sought for a tumour in the upper gastrointestinal tract. Calculations of the valency of the test showed a good efficiency, sensitivity and specificity.

[Antithrombin III: reference values found with a chromogenic substrate (chromozym TH) (author's transl)].

A new kinetic assay for antithrombin III (heparin-cofactor) in plasma was used to determine reference values. Ranges of 10--15 IU/ml at 25 degrees C and 20--29 IU/ml at 37 degrees C were found for a reference population of 219 men and 204 women 15--93 years of age. There was no evidence that these values vary with age or sex, nor was there any difference between pre- and postprandial antithrombin activities, or between smokers' and non-smokers' values. None of the illnesses present in the reference population nor any related drug therapy affected the antithrombin III level, and there was no statistically significant difference between the values for women taking oral contraceptives and those who did not. However, this latter observation does not preclude the possibility of individual variation.
