Die Sauerstoffarmut stellt für einen Teil der Tumorzellen, die aus dem Wachstum solider Tumoren entstehen, im besonderen Maße für die Strahlentherapie und auch für die Chemotherapie ein Hindernis dar. Um dieses Hindernis, das zum Teil für die lokale Rezidivierung und die maligne Progression von Tumoren verantwortlich ist, zu einem neuen Ansatzpunkt für die Therapie zu machen, hat man Substanzen wie das Tirapazamine (TPZ) entwickelt, die unter Sauerstoffarmut ihre tumortoxische Wirkung entfalten....

The existence of a melatonin rhythm in the domestic pig with respect to the light intensity has been discussed controversally. These controversial results are caused in part by inappropriate RIA methods. Until now, there are no published results describing non-immunological identification of melatonin in the domestic pig. Therefore, the main-objective of this study was to establish a HPLC method for the determination of melatonin in plasma and saliva samples of domestic pigs and to examine the c...

In einem Langzeitversuch an adulten Fischer-Ratten wurden die Auswirkungen einer unzureichenden und einer marginalen Zinkversorgung auf den Knochenstoffwechsel untersucht. Den Zinkmangeltieren wurde mit Hilfe einer phytathaltigen, semisynthetischen Diät körpereigenes Zink entzogen. Dabei wurden die Ergebnisse mit paargefütterten Kontrolltieren verglichen. Das Ergebnis der Studie ist, dass Zinkmangel keine nennenswerten Auswirkungen auf den Knochenstoffwechsel hat.

The aim of the present study was to make a statement about selected blood ingredients for twelve pig breeds regarding the influence of the genotype. A possible race-dependence was proved for haematological parameters especially for erythrocytes, thrombocytes and leucocytes. Differences between the breeds were also found for electrolytes and the trace elements although a statement concerning breed-specifity was more difficult because some other environmental factors can have strong influence on t...
