ABSTRACT
<p><b>OBJECTIVE</b>To estimate the therapeutic effect of single or combined use of jasminoidin and cholalic acid on focal cerebral ischemia rat with magnetic resonance-diffusion-weighted imaging (MR-DWI) technique, ultra-microscopy, and neuro-behavior scoring.</p><p><b>METHODS</b>The model of cerebral ischemia-reperfusion injury was induced by string method. Three hours after reperfusion, MR-DWI was applied with ultra-microscopy and neuro-behavior test to give evaluation on cerebral ischemic rats, and pathologic, ultramicroscopic observation of tissue were taken as adjuvant measures to comprehensively evaluate the pharmacological effect on ischemia-reperfusion rats and delimit the efficacy of the two different components and their combination.</p><p><b>RESULTS</b>Compared with the model group, ADC and DCavg values of the foci in all the treated groups had the incrensing trend. There was significant difference arund the foci in the group of combined use of jasminoidin and cholalic acid (P < 0.05).</p><p><b>CONCLUSION</b>Combined use of jasminoidin and cholalic acid had protective effects on nerve and brain. MR-DWI technique accompanied with ultramicroscopic observation of tissues and neuro-behavior test is an effective method for evaluating the effect of neuro-protective agent.</p>
