Summary
The possibility of a tumor-protective effect of selenium on the growth of benzpyrene-induced sarcoma was studied in an assay with Balb/c mice. The animals received 4 parts/106 selenium in their drinking water for 12 months prior to subcutaneous injection of benzpyrene to induce sarcomas. In contrast to unpretreated controls, the selenium-exposed animals developed significantly less and smaller tumors in a given time. These results are compared to those of other authors. Several mechanisms fo selenium influence on benzpyrene metabolism are discussed.
Zusammenfassung
Es werden Untersuchungen zur Frage einer tumorprotektiven Wirkung von Selen auf das Wachstum eines Benzpyren-induzierten Sarkoms vorgelegt. Dazu erhielten Balb/c-Mäuse 12 Monate 4 ppm Selen im Trinkwasser. Danach wurden mit subcutaner Injektion von Benzpyren Sarkome erzeugt. Es zeigte sich, daß die Selen-exponierten Tiere im Gegensatz zu den Kontrollen signifikant weniger und kleinere Tumoren entwickelten als die Kontrolltiere. Die eigenen Beobachtungen werden mit denen anderer Autoren verglichen, Möglichkeiten des Einflusses von Selen auf den Benzpyren-Stoffwechsel werden diskutiert.
