摘要
以SD大鼠和小鼠为实验动物,检测和比较了增效抗凝血灭鼠剂对凝血时间(CT)和凝血酶原时间(PT)的影响,并观察增效抗凝血灭鼠剂中毒鼠的肝脏组织病理变化。结果表明,增效杀鼠醚能引起SD大鼠和小鼠的CT和PT显著延长,相对于杀鼠醚,相同浓度的增效杀鼠醚具有更强的抗凝血功能;中毒鼠肝脏病理学观察结果发现,增效灭鼠剂引起更严重的肝组织损伤、坏死,进一步阻碍其凝血功能,其中增效杀鼠醚对SD大鼠的影响程度大于小鼠,说明增效杀鼠醚对SD大鼠作用效果更明显。
The present studies investigated synergistic rodentieide effect on SD rats and mice, and compared different effcts on coagulation time（CT） and prothrombin time（PT） in SD rats and mice and pathologicaltissues in liver. The results showed that synegistic rodenticide induced a prolonged CT and PT in SD rats and mice respectively, and there were significantly prolonged CT and PT compared with warfarin alone, which suggested synegistic rodenticide had more powerful anticoagulant effect than traditional warfarin. Pathological observation indicated that synegistic rodenticide induced more necrotic liver in toxic rats and mice. All results showed that synegistic rodenticide had a more significant effect on SD rats.
