在进行周围血片白细胞分类的同时,应注意对白细胞、红细胞、血小板的形态进行观察,这对许多疾病,特别是血液病的诊断有着重要意义。一、白细胞形态的观察及其临床意义(一)中性粒细胞要着重观察胞体和胞核的大小、核形、染色质、核膜及包含物的变化1.大小;正常时直径10～15微米。在病程较长的化脓性炎症病人血片中,可见其大小悬殊。在巨幼红细胞性贫血或理化损伤者,血片中可见其胞体和胞核明显增大,呈巨变,尤以杆状核巨变为著。
In the peripheral blood leukocyte classification at the same time, should pay attention to the morphology of leukocytes, red blood cells, platelets observed, which for many diseases, especially the diagnosis of blood diseases is of great significance. First, the observation of white blood cell morphology and its clinical significance (a) of neutrophils to focus on observation of the size of soma and nuclei, nuclear, chromatin, nuclear membrane and inclusions change 1 size; normal diameter of 10 to 15 Micron. In the longer course of purulent inflammation in patients with blood films, we can see the size disparity. In megaloblastic anemia or physical and chemical damage, blood cells showed that their somatic cells and nuclei were significantly increased, showing a great change, especially in the rod-shaped nucleus changes.
