观察了70例急地白血病骨髓白血病细胞的核小体,发现其核小体大小为0.94～5.3μm.M_4的核小体大小与M_1、M_2、M_3比较,M_5与M_2、M_3比较均有显普差异.核小体形态可分为芽生孢子状(77.3%)、气球状(9.5%)、棒状(7.5%)、逗点状(5.7%)四种,气球状核小体在急淋中少见,在M_4中可多达26.7%.急性白血病含核小体细胞数与正常对照组比较,P<0.001;急淋与急非淋比较.P<0.001;在急非淋中,M_3与M_1、M_2比较,P<0.001,与M_4比较,P<0.05.
The nucleosome size of 70 acute leukemia myeloid leukemia cells was observed and found to be 0.94-5.3 μm in nucleosome size compared with M_1, M_2, M_3.M_5 and M_2, M_3 were significantly There are four types of nucleosomes: sporulation (77.3%), balloon (9.5%), rod (7.5%) and comma (5.7% Rare in M_4 can be as high as 26.7% .The number of acute leukemia cells containing nucleosomes compared with the normal control group, P <0.001; acute lymphocytic and acute non-leaching, P <0.001; acute non-lymph node, M_3 and M_1 , M_2, P <0.001, compared with M_4, P <0.05.
