Radiographic Image and Calcium Metabolism after Experimental Fracture of the Metatarsus in Chicken

병아리 부전골에서 실험적 골절후의 방사선 사진상과 칼슘대사

This study was undertaken to analyze the changes of radiographical image in avian (chicken) by using scanner and ${\gamma}-camera$ with $Tc^{99m}-MDP$. Experiment was aimed also to observe the changes of calcium, phosphorus and alkaline phosphatase activity in serum after experimental fracture. The results obtained are summerized as follows. 1. 10 chickens grown 6 weeks were scanned within 48 hours after experimental fracture, showed localized increase in uptake. The earlist increased local uptake was observed after 7 hours from experimental fracture at the fracture site. 2. Serum alkaline phosphatase level was increasing continuously during the fracture healing process in comparison with control group and serum alkaline phosphatase activity showed a peak after 2 weeks following the fracture. 3. The change of Ca. amount in serum trended to decrease from 1st day after fracture and it was in the lowest level at the 7 day's group following the fracture. 4. Serum phosphorus level trended to increase after fracture and it was in the highest level at the 7 day's group and showed similar level in comparison with control group.
