[A simple method for 14CO2 measurement in metabolic experiments].

The determination of the fate of a compound following administration can be performed using the disposition method with 14C-labeled substances, which also allow the measurement of metabolism with CO2 as an expired end product. To substitute the laborious CO2-collection in washing bottles as carbonate a simple instrumentation was built for continuous 14CO2-measurement. The air from the metabolic cage is led in thin layer through a chamber fitted to a foot-monitor, the output of which is online for computation.

[Prevention of postoperative thrombo-embolism by heparin/dihydroergotamine (author's transl].

Using the radiofibrinogen test and perfusion lung scanning (2-phase pharmacoscintigraphy), the incidence of postoperative thrombosis and pulmonary embolism was determined in a group of 362 operated patients. Low-dose heparin administration (twice 5000 IU daily) was given to 162, combined heparin and dihydroergotamine administration (5000 IU heparin and 0.5 mg dihydroergotamine daily) to 150, while 50 patients received no prophylactic treatment.
