Effects of rhynchophylline on monoamine transmitter contents of striatum and hippocampus in cerebral ischemic rats
摘要
Abstract
AIM To explore the protection mechanism of rhynchophylline(Rhy)on cerebral ischemic injury.METHODS The cerebral ischemic injury of rats was induced by middle cerebral artery occlusion.The extracellular fluid of striatum and hippocampus in cerebral ischemic rats was collected by using microdialytic approach at 30,60,90 and 120 min,respectively.Then norepinephrine(NE),5-hydroxyindoleacetic acid( 5-HIAA),3,4-dihydroxyphenylacetic acid(DOPAC)and homovanillic acid(HVA)were measured with reverse phase high performance liquid chromatograph-electrochemical detector.RESULTS Cerebral ischemic induced decreases in extracellular 5-HIAA,DOPAC and HVA in striatum and hippocampus,but NE was increased.Rhy inverses the changes in 5-HIAA,DOPAC,HVA and NE in cerebral ischemic rats.CONCLUSION Rhy can regulate release and metabolism of the intracerebral monoamine transmitters in striatum and hippocampus of cerebral ischemic rats.关键词
