The ir expressions of CD62P and CD41/CD45 in peripheral blood were determined before and after treatment by whole blood flow cytometry with special marked antibody, and compared with those in 10 healthy persons of the same age as a normal cont rol group. Results: Amount of expressions of CD62P and CD41/CD45 (FC%) in UA patients before treatment were 24.22±7.92 and 25.89±8.10 respectively, all hig her than those in the control group ( P <0.01 and P <0.05). After treatment , CD62P lowered to 20.42±8.01, significantly different from that of before tr eatment( P <0.05), and CD41/CD45 also showed a trend of lowering ( P >0.05). Platelet adhesion rate reduced significantly ( P <0.05) at the same time, as compared with that of before treatment.Conclusion: Highly platelet activated state exists in UA patient s. XZP could inhibit platelet membrane glycoprotein CD62P and CD41/CD45 express ions, which might be the molecular mechanism of it in antagonizing PA.展开更多
