[Electron-radioautographic study of the effect of potassium orotate on RNA and protein synthesis in fibroblasts during experimental wound healing].

Electron microscopic radioautography with the use of the double-labeling technique was applied to study potassium orotate influence on RNA and protein synthesis in fibroblasts of intact mouse skin and in granulation tissue on days 3 and 7 of the healing of a musculocutaneous wound. Experimental animals received potassium orotate per os in a daily dose of 0.2 g/kg immediately after operation. Intact animals received the drug for 3 days. According to the assay data potassium orotate did not potentiate the protein-synthesizing activity of an individual cell but apparently activated the proliferation of wound fibroblasts.
