目的 探讨冠心病患者血小板膜上蛋白酪氨酸磷酸酶(CD148)的变化。方法 采用流式细胞仪三色免疫荧光分析检测健康老年人和冠心病患者血小板膜上蛋白酪氨酸磷酸酶(CD148)的阳性百分率、蛋白酪氨酸磷酸酶(CD148)的几何荧光强度、P-选择素(CD62P)的阳性百分率、P-选择素(CD62P)的几何荧光强度及膜糖蛋白Ⅱb/Ⅲa复合物(PAC-1)的阳性百分率、膜糖蛋白Ⅱb/Ⅲa复合物(PAC-1)的几何荧光强度的表达水平。结果 冠心病患者和健康老年人的血小板膜CD62P、CD62P几何荧光强度表达量相比较(6.24 vs 0.89,P
Abstract
Objective To investigate the changes in tyrosine phosphatase(CD148),P-selection (CD62P) and glyco1protein Ⅱb/Ⅲa(PAC-1) in platelets of elderly patients with coronary heart disease(CHD).Methods CD148,CD62P and PAC-1 in platelets were analyzed by flow cytometric 3-color immunofluorescence.Results The percentage and MFI of CD62 expression in the platelet membrane in elderly patients with coronary heart disease(CHD) were increased compared with healthy individuals(6.24 vs 0.89,P
