Abstract
The article presents results on experimental modelling an influence of silver nanoparticles incorporated into natural polymer arabinogalactane matrix on brain tissue of white outbred rats. The rats underwent parenteral injection of silver nanoparticles incorporated into polymer arabinogalactane matrix (dosage of 100 and 500 micrograms of silver per kg of the animal weight). The studies covered expression of 2 proteins participating in apoptosis process, in mitochondrial activation type - caspase-3 and protein bcl-2. During experiment, the groups examined demonstrated significant dose-dependent effect of bcl- 2 protein expression and increased number of caspase-3 expressed and non-expressed hyperchromic cells under exposure to argentumarabinogalactane - that indicates disorders of cellular structure and apoptosis development.
