ABSTRACT
<p><b>OBJECTIVE</b>To explore the effects of total saponins of Rubus parviflolius (TSRP) on brain edema and blood brain barrier in rats.</p><p><b>METHOD</b>The model of local cerebral ischemia was established in rats by reversible inserting a nylon thread into the anterior cerebral artery through the internal carotid artery brain hydrated amount and content change of Evan' s blue (EB) in cortex subjected to 2h middle cererbral artery occlusion (MACO) followed by 6 h, 24 h, 48 h, 72 h reperfusion and effect of TSRP. penetrability of blood brain-barrier (BBB) the index includes brain hydrated amount and penetrability of blood brain-barrier BBB.</p><p><b>RESULT</b>Com- pared with I/R group. Both brain hydrated amount and the EB content decreased significantly in TSRP groups on the 6 h, 24 h, 48 h, 72 h of reperfusion after 2 hour of cerebral ischemia induced by MACO model.</p><p><b>CONCLUSION</b>TSRP could decrease brain hydrated amount and markedly lower permeability of blood-brain barrier subjected to 2 h MACO followed by 24 h reperfusion, and this may be a mechanism of TSRP alleviating brain edema during I/R.</p>
