Abstract

To investigate the effect of simulated in vivo physiological environment severed limb fostering system applying remote ischemic conditioning (RIC) perfusion on preserving severed limb. Eighteen adult Bama mini pigs (24-30 kg in weight) were randomly divided into 3 groups (n = 6). No ischemic treatment was given in group A as normal control group; the right lower limbs were completely amputated and preserved at room temperature for 3 hours to make ischemic models in groups B and C, and then the severed limbs were put into the simulated in vivo physiological environment severed limb fostering system. Continuous blood perfusion was performed in group B, and continuous blood perfusion was performed after RIC perfusion in group C. After 8 hours of perfusion, the skeletal muscle samples were harvested for the morphology observation by transmission electron microscopy. The protein levels of B-cell lymphoma-2 (Bcl-2) and Caspase-3 were detected by Western blot. The content of cytochrome C i...
