Abstract
Twenty four albine mice of forty days old were selected. Twelve forty days old albine mice were irradiated with a Helium-Neon laser source, dose of 10.50566 Jul/cm2. They were divided in two groups acording to time of animal sacrifice (inmediately after irradiation and ten days after). As control were used twelve mice using the same time as the experimental groups, but without radiation. TEM. ultrathin sections showeund alteration only in the conjuctive and in the bone tissues, but not in the epithelial tissue. The bone showed two osteocyte population according to their response to irradiation. The first population showed characteristic comparable with the controls, and the second showed alterations suggestive of a degenerative process. The connective tissue also showed two fibroblasts populations, the first showed signs of a big synthesizin activity, and the second, degenerative signs. The first fibroblast population appeared in the animals sacrified inmediately after irradiation.
