Notes: Abstract Uptake of tungstate by growing cells was unaffected by the presence of molybdate in Clostridium cylindrosporum, whereas in C. acidiurici the accumulation was decreased by molybdate at 10-6 mol/l tungstate and higher concentrations. The labelling pattern of soluble proteins by 185W-tungsten indicated after gel chromatography the presence of three different tungstoproteins in both bacteria. Formate dehydrogenase activity always eluted at a maximum of tungsten labelling. The incorporation of tungsten into formate dehydrogenase containing fractions and a possible tungsten-binding-storage protein was independent of the presence of excess molydate pointing to a genuine role for tungstate in these bacteria.

Description / Table of Contents: Zusammenfassung Primäre Sarkome der Arteria pulmonalis sind seltene Tumoren. In der Welt-literatur wird über insgesamt 81 Fälle berichtet. Davon sind 17% Leiomyosarkome. Die meisten dieser Tumoren werden nicht während des Lebens, sondern häufig zufällig bei der Autopsie entdeckt. Das primäre Leiomyosarkom der A. pulmonalis ist also ein ganz besonders seltener Tumor. Wir berichten über zwei klinische Fälle und geben einen Überblick über die Literatur.

Notes: Summary Sarcoma of the pulmonary artery is a rare tumor. Only 81 cases are reported in the international literature. Leiomyosarcoma of the pulmonary artery is seen in 17% of these tumors. Most of them are not recognized during life but accidentally found at autopsy. So primary leiomyosarcoma of the pulmonary artery is a very rare tumor. We report about two new clinical cases and give a review of the literature.
