查询词典 neuron

To detect effects on apoptosis of cortex neuron in DHCA rats, the rat model of occluding bilateral common carotid artery in the deep hypothermic (21C) rats had been established, and flow cytometry, TUNEL, electron microscope, immunohistochemistry and RT-PCR had been studied.: part I: To establish a new rat model of cerebral ischemia/protect during DHCA: 20 SD rats were used in the experiment, little animal respirator was to assist anesthetized rat's respiration after tracheal cannula, artery press through artery spile in femoral artery, electrocardiograph, temperature, blood saturation of O2 (SaO2) and arterial blood gases were monitored during the whole experiment, blood flow of bilateral common carotid artery of rat were occluded about 60 minute when its temperature was reduced to 21 C by ice, then normal temperature was resumed.
