“核左移”是指周围血象内嗜中性白细胞核的变化。嗜中性白细胞的核象改变可分为幼稚型,杆状核型及分叶核型三类.在正常情况下,周围血象中看不见幼稚型,杆状核细胞仅占1～4%,多数为分叶核型.周围血象中杆状核增多,甚至可出现幼稚型细胞,包括晚幼粒、中幼粒、早幼粒等细胞称为“核左移”,常见于各种细菌性感染,尤其是急性化脓性感染.核左移程度与感染严重及机体反应能力有密切关系.所以临床上观察白细胞计数与核左移的程度对估计病情变化有一定意义.核左移伴有白细胞总数增加称为“再生性核左移”,表示机体对各种感染的抵抗力较强.而高度核左移(周围血象中
“Nuclear left shift” refers to changes in peripheral blood neutrophil nuclei. Neutrophil nuclear changes can be divided into naive, rod-like karyotype and leaflet karyotype.In normal circumstances, the peripheral blood can not see the naive, only 1 to 4% of the nucleated cells, The majority of lobular karyotype.The peripheral blood of the rod-shaped nucleus increased, and even may appear naive cells, including late promyelocytic, promyelocytic, promyelocytic and other cells called “left shift”, common in a variety of bacterial Infection, especially acute suppurative infection.Nuclear left shift and severity of infection and the body’s ability to respond to a close relationship so clinical observation of white blood cell count and the extent of left nuclear shift has some significance in the estimation of disease changes.Nuclear left shift accompanied by leukocytes The increase in the total number is called “regenerative nuclear left shift”, indicating that the body is more resistant to various infections, while the height of the nucleus is shifted to the left
