Application of radionuclide imaging to hepatic impact injury in rabbits.

Objective: To investigate the role and clinical value of radionuclide imaging in hepatic impact injuries in rabbits.

Methods: Rabbits were experimentally impacted on the liver with BIM-IV bio-impact machine. Liver imaging was performed with 99mTc labeled sodium phytate.

[Effect of vascular endothelial growth factor in fracture healing].

Objective: To observe the effect of vascular endothelial growth factor (VEGF) in fracture healing and to investigate the influence of VEGF and VEGF antibody in fracture healing.

Methods: One hundred and five rabbits were used to make fracture model in the left radius and randomly divided into control group, VEGF group and VEGF antibody group. VEGF and VEGF antibody were used in the VEGF group and VEGF antibody group respectively, then the blood flow of the fracture ends was measured by single photon emission computed tomography (SPECT) 8, 24, 72 hours, 1, 3, 5 and 8 weeks after fracture, the X-ray films of the fracture sites were taken after 1, 3, 5 and 8 weeks to observe the fracture healing.
