The present study was designed to elucidate the effects of the Co-60 ¥ã irradiation
and/or calcium-deficient diet on the periodontal tissue formation in rat pups. The
pregnant three-week old Sprague-Dawley rats were used for the study. The
experimental group was divided into two groups, irradiation/normal diet group(Group 2)
and irradiation/calcium-deficient diet group (Group 3) The control group was
non-irradiation/normal diet group(Group 1).
The abdomen of the rats at the 19th day of pregnancy were irradiated with single
absorbed dose of 350cGy. The rat pups were sacrificed on the 14th day after delivery.
and the maxillae including molar tooth germ were taken. The specimens including the
1st molar tooth germ were prepared to make tissue sections for light and transmission
electron microscopy. Some of tissue sections for light microscopy were stained
immunohistochemically with anti-fibronectin and anti-osteonectin antibodies.
The results were as follows :
1. In the periodontal ligament forming area, the fibroblasts of Group 2 showed
irregular arrangement and low activity. The immunoreactivity between the fibroblasts
and collagen fibers was decreased, compared with Group 1. The fibroblasts of Group 3
showed atrophic change and clumped nucleus. The collagen fibers showed cystic change
and low immunoreactivity to the fibronectin.
2. In the cementum forming area, the cementoblasts of Group 2 showed decrease of
number and atrophic change. The cementoblasts of Group 3 showed edematous change,
atrophy of cytoplasm, and clumping of nucleus.
3. In the alveolar bone forming area, the bone of Group 2 was thin and various
degree of immunoreactivity to the osteonectin. Group 3 showed edematous osteoblasts,
fibrous degeneration of bone marrow, and weak immunoreactivity to the osteonectin.
