Two experiments were carried out by using atomic absorption spectroscopy on the stability and dose-dependence of cisplatin [cis-diamminedichloroplatinum (II)] binding to blood proteins and tissue DNA of male Han/Wistar rats. The dose-dependence was studied by injecting 17 rats i.p. either with cisplatin (4.4, 8.0 or 11.0 mg/kg) or 0.9% NaCl (controls). The(More)
A method based on cation exchange chromatography was developed to determine the adducts formed in the reaction of cis-diamminedichloroplatinum(II) (cis-Pt) with DNA. DNA was incubated with various concentrations of cis-Pt for various periods of time, ethanol precipitated, and enzymatically digested to nucleosides and Pt-containing oligonucleotides. The(More)
