title: Wound healing process in the portio vaginalis uteri after CO2-laser treatment.
abstract: In order to determine the would healing process in the portio vaginalis uteri, 3[H]-thymidine incorporation and hydroxyproline concentration in the granulation tissue were measured histochemically after CO2-laser treatment. As a result, the squamous epithelium showed the thymidine uptake in extended regions in the first week and in basel cell hyperplastic regions in the second week. The uptake was seen in the reserve cell hyperplastic regions of the epithelium from the 2nd week. Hydroxyproline concentration peaks mostly appeared within one week after the laser treatment. After cryosurgery, the peaks mostly appeared after two weeks or more. These results indicated that, the stromas and then the squamous and columnar epithelial cells in turn were regenerated after CO2-laser treatment, and that the regeneration occurred earlier after laser treatment than after cryosurgery.
