[Study on ultrastructure of platelets in migraine patients with blood stasis type].

To study the relationship between ultrastructure of platelets and migraine patients with blood stasis type (MBS). The morphologic appearance and aggregation of platelets in MBS patients were examined before and after treatment with Tongbike oral liquor (20 cases in treated group and.10 in control). The results showed that the MBS patients' platelets appeared irregular, easy to aggregate and adhere to red cells, which was more severe when ADP was added, but improved after treated with Chinese medicinal herbs. According to the results it was assumed that platelets from MBS patients were in an abnormal activated state, the abnormal morphology and functional disturbance might be the pathologic basis of MBS. Tongbike oral liquor could markedly improve the morphologic and functional state of platelets, which was relevant to the inhibition of platelet aggregation and the inducing of platelet depolymerization.
