    The in vitro study was carried out for detection of the cisplatin in free form and in culture medium, depending on various conditions of sonodynamic human ovarian cancer cells A2780 treatment by differential pulse polarography (DPP). For sonodynamic treatment, we used cisplatin alone and combined cisplatin/ultrasound treatments. The ultrasound exposure intensity of 1.0 and 2.0 W.cm(-2) in far field for incubation periods 1, 24 and 48 h was used.. The parameters of DPP measurements were - 1 s drop time, 5 mV.s(-)1 voltage scan rate, 50 mV modulation amplitude and negative scanning direction; platinum wire served as counter electrode and AglAgCII3 M KCl as reference electrode. The results showed the dependence of free platinum quantities in culture medium on incubation time and treatment protocol. We found difference in concentration of free cisplatin between conventional application of cisplatin and sonodynamic treatment.
