血液学研究历程中大概渡过了三个时期:即1856～1926年的形态学时期,其后的病理生理学时期;1945年以后的化学时期,目前已进入机能与动态时期。近年来由于细胞培养技术的提高,放射性同位素的应用,以及实验免疫学的进展为造血细胞演化过程的研究提供了实验方法及理论根据,为指导临床实践提供了新 Hematology research process probably spent three periods: the morphological period 1856 ~ 1926, the subsequent pathophysiology period; 1945 after the chemical period, has now entered the function and dynamic period. In recent years, due to the improvement of cell culture technology, the application of radioisotopes, and the progress of experimental immunology provide experimental methods and theoretical basis for the study of hematopoietic cell evolution, which provides a new guide for clinical practice
