The aim of the experiment was to study the effect of three specialized food rations on activity of superoxide dismutase (SOD) in tissues of rats with transplanted Walker's carcinosarcoma 256 exposed to carminomycin. It was shown that the three specialized rations were able to significantly modify the SOD activity in the tissues of the rats with Walker's carcinosarcoma 256 at the background of treatment with carminomycin. Thus, the ration enriched with copper and zinc salts and folic acid activated SOD in the animals of all the groups. Still, the effect was higher in the tumor-bearing animals and the rats treated with carminomycin i.e. under conditions of oxidative stress. The use of the ration enriched with sulfur-containing amino acids, sodium selenide and vitamin E led to decreasing of the efficiency of the fermentative dismutation of O2 in the healthy rats and marked activating of SOD in the tumor-bearing animals. The ration containing lyophilized vegetables and vitamin E provided a significant increase in the SOD activity in the healthy rats. However, its potential was not sufficient for overcoming the SOD inhibiting effect of the tumor growth. |
