A toxin that causes morphological changes in Chinese hamster ovary cells was isolated from a culture filtrate of Shigella dysenteriae 1. It was partially purified by successive column chromatography on diethylaminoethyl-cellulose, Bio-Gel A-5m, and hydroxylapatite. The toxin was separated from neurotoxin by diethylaminoethyl-cellulose column chromatography and was not lethal for mice.

Abstract Silica-/calcium phosphate ceramics are of high interest in various aspects. On the one hand, they play an important role medical applications due to their excellent biocompatibility. Therefore, detailed knowledge formation and stability properties high-temperature products ensures production under controlled conditions. other were identified as sinter deposits industrial kilns, where i...
