应用扫描电镜检测血栓形成

Using Scanning Electron Microscope to Examine Thrombus Formation

目的探讨血栓形成的诊断指标。方法选择冠心病、心绞痛、大脑供血不足患者和无遗传病的卫校学生,分别从静脉采血0.5 ml,用扫描电镜观察、对比。结果冠心病、心绞痛、大脑供血不足患者的血液中均有不同程度的红细胞叠加、粘连和微血栓(红、白、混合栓<0.5 mm);卫校学生的血细胞正常,无红细胞叠加、粘连和微血栓。结论血液中出现红细胞叠加、粘连是血栓形成前期的超微病理改变;微血栓是血栓形成早期的超微病理改变。

Objective To investigate the diagnostic standard of thrombus formation. Methods Select patients with coronary heart disease （CHD）, angina pectoris or cerebrum blood supply insfficiency as well as the healthy students from Higiene School to pith the blood separately form their veins （0.5 ml）. Observe and contract the blood sample under the scanning electron microscop. Results The blood of each patient has erythrocyte superimposition,adhesion and microthrombus formation （red pale and mixed thrembus 〈 0.5）,which is only different in degree.While the blood of the healthy students is normal,which has no erythrocyte superimposition,adhesion or microthrombus formation. Conclusion The erythrocyte superimposition and adhesion in patient＇s blood is the micro pathology change of the earlier period of the thrombus formation ; and the micro thrombus is the micro pathlolgy change of the earlier period of the thrombus formation.
