[Destruction and division of cells of the mesenchyma of the intestinal tube during the period of histogenesis].

The mesenchyma of the intestinal tube of chicken's and crocodile's embryos was studied light-optically. In order to study the mitotic activity and signs of the cell degeneration the cells were counted per mille by the same method in both objects. According to our ovservations the character of relationships between processes of proliferation and death of cells permits the effects of necrosis processes on the mitotic activity of mesenchyma cells to be supposed.
