Abstract:
AIM To investigate the possibility of microvolume rodent ventilator in improving the quality of global ischemia-reperfusion injury model in mice. METHDOS Global cerebral ischemia-reperfusion injury was preduced in mice by obstructing and decompressing bilateral common carolid arteries and pressuring and decompressing cervical soft tissue, artificial respiration was performed using rodent ventilator before those procedures. EKG, ECG was detected and pathological examination. RESULTS Rodent ventilator was used to keep essential physiologic ventilative volume befer pressure, EKG change was not been found in observed duration in all animals. The suppressed cephalograph was displayed continuously in various time in ischemic and reperfusion injury. Pathological examination indicated that the damage was worse progressly in cerebral cortex and hippocampus, as times of ischemic and reperfusion prolonged. CONCLUSION Using microvolume rodent ventilator success rate and stability is increased obviously in model of global cerebral ischemia-reperfusion injury in mice and mortality was decreased greatly.
