Experimental studies on the anti-thrombosis effect of 3,4-oxo-isopropylidene-shikimic acid / 药学学报

ABSTRACT

<p><b>AIM</b>To study the effect of 3,4-oxo-isopropylidene-shikimic acid (ISA) against arteriovenous shunt and middle cerebral artery thrombosis (MCAT) in rats.</p><p><b>METHODS</b>Arteriovenous shunt model was adopted to measure thrombus weight; The neurologic deficit (ND) and the infarct size (IS) of the middle cerebral thrombosis (MCAT) model induced by FeCl3 were observed; The effect of ISA on platelet aggregation rate of rat and rabbit by giving ISA in vivo and in vitro was studied.</p><p><b>RESULTS</b>ISA 25, 50, 100 and 200 mg.kg-1 ig was shown to reduced the weight of thrombus in arteriovenous shunt model; ISA 50, 100 and 200 mg.kg-1 ig for 2 times in 24 hours, attenuated the ND of rats subjected to MCAT; ISA 100 and 200 mg.kg-1 reduced IS of rats after MCAT by 27.8% and 31.6%, respectively; ISA 50, 100 and 200 mg.kg-1 ig inhibited platelet aggregation of normal rats; ISA 10(-3)-10(-5) mol.L-1, inhibited rabbit platelet aggregation in vitro.</p><p><b>CONCLUSION</b>ISA inhibited thrombosis by anti-platelet-aggregation.</p>
