[The role of the muscle cell nucleus in the mechanism of its transformation after infection by Trichinella spiralis larvae. II. Histochemical features of the functional transformation of the muscle cell nucleus in the course of infection].

The activation of muscle cell nucleus in the course of T. spiralis infection, established using morphological methods (part I), has been confirmed in histochemical (histones, RNP) and histoenzymatic (RN-aze) investigations. The activity of the cell nucleus increased from the 5th day after infection up to the complete encapsulation of the larva (30th day) however it remained at a weak stable level in later stages of infection.
