Abstract:
The changes in biomechanics of rat thoracic aorta at different post mortem interval (PMI) (0-7 d) were observed when it was stretched in one direction. Some significant changes were disclosed by statistical analyses. Maximum stretch, maximum strain and maximum energy showed a significant relationship with PMI, the coefficients of determination being 0.822, 0.716 and 0.669 respectively, P < 0.001. The stretch experiment of thoracic aorta may be a novel method to determine PMI.
