Experimental study on the effect of radiation in the secondary palate formation

Journal Article:

Abstract

The author observed the effect of X-ray irradiation on the secondary palate formation of the rat fetuses. The mothers were exposed to X-radiation on the 10 1/2th, 11 1/2th, and 12 1/2th day of gestation with respectively 150, 200, 250, 300, and 350 rads. The fetuses were removed from mothers on 15 1/2th, 16 1/2th, and 18 1/2th day of gestation. Morphological changes in palate formation were examined and histochemical preparations were made. 1. In control fetuses, the secondary palates were fully developed on the 15 1/2th, to 18 1/2th day of gestation. But in experimental fetuses, many cleft palates were observed in accordance with increase of X-radiation dose. 2. Frequency of incidence of horizontal position of both palatal shelves in cleft palate was highest. 3. According to the dislocation of palatal processes, the stain ability of palatal crest was varied. 4. The thickened area of palatal epithelium of palatal crest showed intense methyl green-pyronin and PAS reaction 5. Mesenchymal cell condensation was appeared under the thickened epithelium of palatal process and this mesenchymal tissue showed strong colloidal iron reaction. 6. The stain ability of alizarin red S and alkaline phosphatase reaction of tectal ridge were decreased in accordance with  More>>
