Abstract
30 female C57 bl. mice were treated with Adenocarcinoma im. in the right hind leg. Three days later cis-dichlorodiamine platinum was applied orally /15 mg/kg/ to all animals and additional 0.05 mg Prednisolone i.p. to 20 animals. Tissue samples from bloods, livers, kidneys, spleens, hearts, lungs, tumors and gastrointestinal tract were analyzed for their Pt concentration after therapy with cis-dichlorodiammine platinum complexes and Prednisolone by instrumental neutron activation analysis. Even 5 animals were sacrified. The amount of Pt in most of the organs examined remained under 0.05% of the quantity applied. Maximum values were detected at the end of the experiment, except for the gastrointestinal tract, the liver and the kidneys. Treatment of the animals with Prednisolone did not produce a significant different distribution of Pt. Only in tumor tissues a significantly higher amount of Pt was observed after Prednisolone treatment at 48 h but not at 72 h. Blood levels increased with time after Prednisolone treatment, without Prednisolone blood levels decreased.
