[Changes in the mechanical properties of the femur and jaws in dogs with osteoporosis due to a single acute whole-body irradiation].
The authors studied the condition of the mineral component and the mechanical properties of different parts of the femur and jaws in 27 dogs; 12 of these dogs were exposed to a single acute total irradiation by a dose of 4.0 Gy. The development of osteoporosis and diminished firmness of the femoral spongy structures were revealed: no marked changes occurred in the cortical bone tissue due to the relative inertness of its metabolic structures. Signs of osteoporosis were found in the region of the frontal and masticatory teeth of the mandible.
