对３０例健康老年人骨髓细胞分类及形态学进行了观察，结果发现健康老年人骨髓原始和各种幼稚位细胞降低，杆状和分叶核粒细胞正常；原始红细胞降低，各种幼稚红细胞增高；原始、颗粒和裸核巨核细胞正常，幼稚巨核细胞降低，产板巨核细胞增高；淋巴细胞降低；浆细胞增高；原始单核细胞正常，幼稚和单核细胞降低；巨噬细胞增高；红细胞系细胞形态学可见点彩晚幼红细胞、花瓣样晚幼红细胞、幼红细胞核分裂相和嗜碱性点彩红细胞，其它系列细胞形态正常。本文还对健康老年人骨髓细胞分类及形态学变化的原因进行了分析。
The classification and morphology of bone marrow cells in 30 healthy elderly were observed. The results showed that the bone marrow and various naive cells in healthy aged people were reduced, and the rod-shaped and segmented nucleated granulocytes were normal; the original erythrocytes were decreased and all kinds of immature erythrocytes were increased ; Primary, granulocytes and naked nuclear megakaryocytes normal, naive megakaryocytes decreased, plate megakaryocytes increased; lymphocytes decreased; plasma cells increased; naive monocytes were normal and monocytes decreased; macrophages increased; erythrocytes The morphological changes were observed in late-blooming erythroblasts, petal-like late erythrocytes, immature erythrocytic mitochondria and basophilic erythrocytes, and the other cell lines were normal. This article also analyzes the reasons for the classification and morphological changes of bone marrow cells in healthy elders.
