正常状态下血小板的结构与机能已逐为人们所认识,并对血小板有多功能细胞之称。近20余年来对其超微结构了解较为清楚,在此基础上对某些异常状态下血小板的结构和机能的研究,也就逐渐为基础医学和临床医学的学者所重视,国外有关报道较多,研究较为详细。本文就某些异常状态下血小板超微结构作一概述。根据异常状态下血小板结构的缺陷和变化及其机能紊乱,大致分为以下四类: Under normal conditions, the structure and function of platelets have been known by people as well as multifunctional cells on platelets. More than 20 years to understand its ultrastructure more clearly, on the basis of some abnormal state of the structure and function of platelets, it gradually for the basic medical and clinical scholars attention, more foreign reports , The study is more detailed. This article gives an overview of some abnormal conditions of platelet ultrastructure. According to the abnormal state of platelet structure defects and changes and their disorders, can be divided into the following four categories:
