Nowadays the research of the mechanisms of cerebral ischemia/reperfusion injmy(CIRI) is mainly focused on the following aspects:excessive generation of free radicals,the exotic effect of excitmy amino acids,inflammatory response and calcium overload.Among them calcium overload and a series of harmful metabolic reactions triggered serve as the key that results in neuron injury and death after GIRI.Here is to summarize the calcium channels existing on the neuron and their changes after CIRI,revealing the neuron calcium overload mechanisms during CIRI,in order to find new t...
