Аннотация Aim: to evaluate the severity of morphological changes in the liver of laboratory animals with prolonged intake of pegilated gold nanoparticles of different sizes from 2 to 50 nm. Material and methods. The experiment was performed on 240 albino rats divided into 4 groups. The animals of experimental groups were orally administered the gold nanoparticles in a specific pattern. Results. Morphological changes in liver depend on the particle size and the duration of administration. Developing pathological changes in the liver are reversible, as evidenced by the gradual recovery of the liver structure 14 days after administration. Conclusion. The most significant changes in the liver were found in the experimental groups with a 30-day administration of 2 and 50 nm gold nanoparticles that show the size-dependent nature of their impact.
