Abstract
Male Copenhagen rats with transplanted prostatic adeno-carcinoma were treated with different polyamine synthesis inhibitors, such as methylglyoxal-bis-guanylhydrazone (MGBG), erythro-9-(2-hydroxy-3-nonyl) adenine (EHNA) combined with 9-β-D-arabin-ofuranosyl-adenine (ARA-A), α-difluoromethyl-ornithine (DFMO), and some of their combinations. Levels of the essential trace elements-copper, zinc, magnesium, iron, selenium, and manganese -have been determined in blood, tumor, kidney, and liver of these animals and are discussed in terms of efficiency of the treatment. MGBG had the strongest effect on trace element levels in tissues of treated animals. MGBG combined with DFMO exhibited the highest antitumor activity of all treatment protocols. Selenium given as selenite with drinking water was used as an adjuvant with the most toxic combination, (ARA-A/EHNA, MGBG). Selenite reduced the toxicity of these therapeutic agents.
