Ultrastructural and functional assessment on platelets loaded with small molecule carbohydrates / 中国实验血液学杂志

ABSTRACT

The aim of this study was to investigate the effect of loading some small molecule carbohydrates into human platelets on ultrastucture and function. The ultrastructure of platelets were observed by transmission electron microscope (TEM); the platelet counts and mean platelet volume (MPV) were measured by hemocytometer, the maximal platelet aggregation rate was measured optically in an aggregometer; the surface marker of platelet membranes CD62p and phosphatidyl serine were analyzed by flow cytometry. The results showed that no significant changes of the ultrastructure of platelets loaded with small molecule carbohydrates were seen. The aggregation responsiveness of platelets loaded with small molecule carbohydrates reached to 60% of the fresh control platelets. The values of platelet counts and MPV showed no significant differences. The expression level of CD62p and the binding rate with Annexin V before and after loading small molecule carbohydrates into platelets were no different. It is concluded that the platelets after loading with small molecule carbohydrates remained fine ultrastructure and function.
