Morphometric investigations (using the convergence analysis method) of geometric parameters of nuclei and nucleoli of transformed muscle cells were carried in mice 15 days, 30 days and 6 month after infection with T. spiralis larvae. The analysis showed the largest increase of investigated the parameters of 15th day after the infection. The results of morphometric analysis are in agreement with the morphologic, ultrastructural and histochemical observations (published in I and II part) as for as functional changes of muscle cells in various stages of trichinellosis are concerned.
