Abstract
One of the properties of nanoparticles is their ability to correct manifestations of oxidative stress and endotoxemia, which are critical factors in cancer development. Therefore, the work aimed to investigate the effect of the usage of Au/Ag/Fe nanoparticles on oxidative stress indicators and endotoxemia parameters in experimental colon carcinogenesis. The study was performed on 90 white male rats kept in standard vivarium conditions. The division into groups: I – intact animals; II – intact animals with 21 days NPs administration; III – animals injected with N,N-dimethylhydrazine dihydrochloride for 30 weeks; ІV – animals to which Au/Ag/Fe nanoparticles were intragastrically administered daily for 21 days after induced adenocarcinoma. According to our results, the concentration of oxidative stress indicators significantly increases under DMH-induced carcinogenesis conditions. It was established that the 21-day intragastric administration of NP Au/Ag/Fe composition caused a significant (P < 0.001) decrease in the concentration of TBARS in the blood serum by 1.33 times, in the content of diene and triene conjugates by 1.63 and 1.98 times, respectively compared to the third experimental group. The introduction of NPs in the fourth experimental group reduces the concentration of the Schiff bases by 1.34 times (P < 0.001), decreases the content of POMP370 and POMP430 by 1.25 (P < 0.001) and 1.37 times (P < 0.001), respectively, compared to the third experimental group. We also observed the reduction of endotoxemia levels in a fourth experimental animal group based on a significant decrease in MMM indexis and EII percentage.
