Effect of glycol mannate sulfate on experimental thrombosis / 中国药理学通报

ABSTRACT

AIM　To investigate the antithrobosis effects of glycol mannate sulfate(GMS). METHODS　Vein thrombus was formed in rat by ligating postcava. Thrombus formation in vitro was observed by Chandlers method. Clotting indexes were measure by ACL200 congulation system. RESULTS　GMS dosage of 20、40 mg*kg-1 could inhibit the vein thrombus formation in rats (P<0.01). GMS could inhibit the thrombosis in rabbit, in vivo, and the inhibitory action was enhanced along with the increase of dosage. The CT,TT,CT,APTT,RT and PT were prolonged, and the fibrinogen and the activity of Ⅱ and Ⅱa were decreased. The activity of ATⅢ was enhenced. CONCLUSION　GMS has antithrombotic effect and the mechanism may be related to the anticongulat effect.
