Bilateral calcaneal intraosseous lipomas: a case report.

A case of bilateral intraosseous calcaneal lipomas in a 40-year-old man is presented. Because of the benignancy and the virtually diagnostic appearance of this lesion radiographically, a bone biopsy was not performed. This may be the first case of bilateral involvement of the calcaneous by intraosseous lipomas.

[The relation between antimycobacterial activity and complex formation of various compounds]. / Zusammenhang zwischen antimykobakterieller Aktivität und Komplexvermögen einiger Stoffe.

Analytic agents were tested from the point of view of their antimycobacterial effect. It was found, that substances forming complexes with Cu-ions, namely dithiocarbamates and their oxidation products, show very high antimycobacterial activity. Small stability of the dithiocarbamates in acidic medium leads to the tests, the aim of which was to replace these substances with chemically stable, but antimycobacterially active compounds. Dibenzoyldisulfide was found as one of these substances.
