[DNA synthesis in connective tissue elements of regenerating skin under the influence of thyrocalcitonin and hypoxia].

The influence of TCT on the proliferation activity of the connective tissue elements of the regenerating skin in normal and lowered partial oxygen tension was studied by means of H3-thymidin autoradiography. Continuous saturation of the organism with exogenous TCT is characterized by an increase in the count of cells during the S-period of mitotic cycle, the DNA synthesis intensification, and a considerable decrease in the number of silver grains over the nuclei in the course of the 24-hour observation period; this can testify to the acceleration of the cell passage of mitotic cycle stages in normal and low partial oxygen tension in hypoxia.
