In cerebral atherothromboembolic accidents it is essential to quickly remove both the thrombotic and cholesterol crystal vascular obstructions. In this study we induced cerebral atheroembolic infarction in adult male NZW rabbits. Post induction we treated groups of animals with saline, streptokinase (SK)-only, or streptokinase and taurochenodeoxycholate (TCDC). The tissues were fixed 24 hours later and the infarcts were then measured. No remarkable damage resulted from the agents' use in the cerebral vascular bed, or in the hepatic parenchyma. Both treatments produced a dramatic reduction in the area and perimeter measurements of the infarcts when compared to control-treated animals. Both SK treatments drastically reduced the sizes of induced infarcts. It is suggested that a combined thrombolytic/emulsification treatment may drastically reduce the extent and distribution of cerebral infarcts which result from cerebral atherothromboembolism.
在脑动脉粥样硬化血栓性栓塞事件中,迅速清除血栓性和胆固醇晶体性血管阻塞至关重要。在本研究中,我们在成年雄性新西兰白兔中诱导脑动脉粥样硬化栓塞性梗死。诱导后,我们用生理盐水、仅用链激酶(SK)或链激酶与牛磺鹅去氧胆酸盐(TCDC)对动物组进行治疗。24小时后固定组织,然后测量梗死灶。这些药物用于脑血管床或肝实质均未导致明显损伤。与对照治疗的动物相比,两种治疗均使梗死灶的面积和周长测量值显著降低。两种SK治疗均大幅减小了诱导梗死灶的大小。提示溶栓/乳化联合治疗可能大幅减少脑动脉粥样硬化血栓栓塞所致脑梗死的范围和分布。
