一、应用扫描电镜对氨肽素治疗前后的慢性血小板减少性紫癜患者的血小板形态变化的观察: 北京中医研究院,取4例氨肽素治疗前后的慢性血小板减少性紫癜患者的血小板,经扫描电镜制样处理后,在电镜下观察到血小板有两种形态,一种是表面光滑很少有伪足,另一种伪足变得基本一样粗,但伪足先端略微膨大呈椭圆锤状,还有的血小板伪足较多,伪足先端分枝尤如树枝状。电镜放大到3000倍时,可看到血小板的一般形态。放大到5000倍时,血小板除显示不同的伪足外,还可观察到其表还
First, the application of scanning electron microscopy of amifostine before and after treatment of patients with chronic thrombocytopenic purpura platelet morphology changes observed: Beijing Institute of Traditional Chinese Medicine, take 4 cases of aminopeptin before and after treatment of patients with thrombocytopenic purpura platelet, after scanning Electron microscopy sample processing, observed under electron microscopy, there are two forms of platelets, one is smooth and few pseudo-foot surface, the other pseudo-foot becomes roughly the same rough, but a little enlarged anterior pseudo-foot was oval-shaped hammer, There are more platelet pseudopods, pseudo-anterior branch especially as a dendritic. Electron microscope enlarged to 3000 times, you can see the general form of platelets. Zoom to 5000 times, platelets in addition to show different pseudo-foot, but also observe the watch also
