bone phosphate
1.Methods: Thirty eight patients with epilepsy and thirty controls were involved. Serum calcium(Ca),serum phosphorum(P),alkaline phosphate(ALP),bone alkaline phosphate(BAP),bone gla protein (BGP),parathormone(PTH),25 hydroxy vitamim D 3 (25(OH) D 3 )and calcitonin(CT) were measured in healthy controls and in treatment group before,3 and 6 month after antiepileptic drugs treatment.
9.The changes of element ratio and components of materials and interface implanted into femur were compared. Thorough studies were made on the transformation of TCP from lifeless materials into living bones after implantation, by using SEM EDXA, Raman spectra and infrared spectra. These results provided rich evidence for understanding biodegration and bone bonding mechanism of calcium phosphate bioceramics.
