Aim: To evaluate the changes of some biochemical blood plasma parameters and morphological structure of the internal organs of rats with transplanted doxorubicin (DOX)-sensitive (Walker 256) and doxorubicin-resistant (Walker 256/DOX) strains of Walker 256 carcinosarcoma. Materials and Methods: The study was performed on female Wistar rats with transplanted Walker 256 or Walker 256/DOX and intact animals (control). On the 9th day after transplantation of tumor cells, a comparative analysis of some blood plasma biochemical parameters and morphological examination of the liver, kidneys, myocardium and spleen of rats was carried out. Results: Walker 256 growth, in comparison with Walker 256/DOX, is accompanied by more pronounced systemic effect on tumor-bearing rats. Uric acid concentration in the blood plasma of Walker 256 bearing rats was significantly (by 15.5%) higher than in Walker 256/DOX bearing rats. Aspartate aminotransferase activity in the Walker 256 group was significantly (by 107.2%) higher than in Walker 256/DOX group, but alanine aminotransferase activity was 58.5% lower. 56.7% decrease of alkaline phosphatase in rats with Walker 256, and 21% increase of this index in rats with Walker 256/DOX were observed. The growth of Walker 256 carcinosarcoma led to greater structural damage of the liver, kidneys and spleen in experimental animals compared with Walker 256/DOX strain. Conclusion: Tumor growth in rats with Walker 256/DOX leads to less pronounced changes in the biochemical parameters of rat blood plasma and morphological structure of internal organs compared with wild-type carcinosarcoma.
