LI Zheng, et al. The reparation of metallothionein to the injuried neuron after cerebral ischemia and reperfusion in rats[J]. Journal of Chongqing Medical University, 2010,35(2):202-205. DOI: 10.13406/j.cnki.cyxb.2010.02.028.
Objective:To observe the protect action of exogenous metallothionein on rats’ cerebral ischemia and reperfusion and explore its possible mechanism.Methods:I/R modle was established.After 20 min ischemia and 1 d reperfusion
determined the ethology index and the HE staining was determined to see the morphologic changes of neurons in hippocampus.The expression of NGF-βin hippocampus was determined by immunohistochemistry. Resluts:Metallothionein cerebral ventricle injection(1.4、4.2 mg/kg)could significantly reduce the ethology symptom by dose dependent
the expression of NGF-βin hippocampus also was increased(0.46、1.4、4.2 mg/kg).Meanwhile
the pathological examination showed that the karyopycnosis of neurons in hippocampus with I/R in rats could be decreased by MT uncommonly
which mitigated the injury of brain. Conclusion:MT can protect the brain from I/R injury
its active mechanism may be related to repair impaired neurones.
