The article presents results of apoptosis evaluation in albino rat neurons using comet assay for DNA and immune histochemical analysis to determine the activity of pro-and anti-apoptotic proteins caspase 3 and bcl-2 at exposure to nano biocomposites representing nano silver embedded in a matrix of a natural arabinogalactan. In preparations of nervous tissue of rats exposed to nano silver arabinogalactan polymer, a statistically significant increase of DNA content in comet tails was found out. DNA comets with DNA tail content of more than 70%, which could be regarded as apoptotic have not been observed in investigated formulations. The results of the immune histochemical determination of expression of anti-and pro- apoptotic proteins bcl-2 and caspase-3 in neurons show on the contrary the development of apoptosis in nerve cells. Comparing results of the studies performed, a conclusion can be drawn that to detect the apoptosis process, immune histochemical methods for determination of anti-and pro-apoptotic proteins are more efficient than DNA comet assay.
