To observe the effects of raw and charred Agi on hemostasis and its mechanism.The rabbit bleeding time was measured by traumatic hemorrhage test, and the clotting time was measured by tube test. The rabbit prothrombin time (PT), activated partial thormboplastia time (APTT), thrombin time (TT), fibrinogen (FIB), plasma recalcification time (PRT), euglobulin lysis time (ELT), max platelet aggregation rate (MPAR) were measured by solidification method, turbidimetry and tube test to analyze the effects of raw and charred Agi on rabbit coagulation-fibrinolysis system and platelet function.The medium doses and high doses of raw Agi groups, all of the groups of charred Agi decreased rabbit BT obviously (P0.01 or P0.05); all of the groups of raw and charred Agi declined rabbits CT (P0.01 or P0.05). All of the doses groups of raw and charred Agi had no apparent influences on PT (P0.05); the high dose of raw Agi group and all of the groups of charred Agi decreased APTT apparently (P0.01 or P0.05) and prolonged ELT (P0.01 or P0.05); the high doses groups of raw and charred Agi decreased TT apparently (P0.01 or P0.05); the medium and high doses groups of charred Agi increased FIB obviously (P0.01 or P0.05); the high doses group of charred Agi showed the decreased PRT significantly (P0.05) and increased MPAR obviously (P0.01).Raw Agi can play its role in hemostasis and coagulation by affecting the intrinsic pathway of coagulation and fibrinolytic system. These effects are inhanced after processing drugs; moreover, the charred Agi could increase FIB and MPAR with promoting more in blood coagulation. |
