Dynamics of nucleic acid synthesis was studied in granulation tissue, harvested within 2-11 days after an injury of rats with full-layer skin wounds, simultaneously with evaluation of the morphometric patterns of the tissue. Synthesis of nuclear DNA exhibited a wave-shaped dynamics. The intervals between the maximal values of the DNA synthesis constituted 3 days. Within the early steps of wound healing the intensive incorporation of 3H-thymidine into mitochondrial DNA was found, which appears to occur due to active mitochondriogenesis. In dynamics of total and nuclear RNA contents two peaks were observed, which did not coincide in time, thus suggesting the wave-shaped increase in biosynthetic processes in cells.
