染色体的研究为血液疾病的诊断,治疗及判断予后提供了重要依据。本文就观察到染色体异常的血液疾病简介如下: 一、白血病 1、慢性粒细胞性白血病(CML) 1960年Nowell和Hungerford二氏在美国弗城首先发现CML患者血细胞中期分裂相中,虽染色体数目仍为46个,但G组中有一个部分长臂缺失的特殊标记染色体(所谓标记染色体,一般是指某一患病个体的细胞中,可以恒定地出现的形态异常的染色体)。这种标记染色体属于22号,即22号染
Chromosome research for the diagnosis of blood diseases, treatment and provide an important basis for judging. This article on the observed chromosomal abnormalities in blood diseases are as follows: A leukemia 1, chronic myeloid leukemia (CML) 1960 Nowell and Hungerford II in the United States first discovered in Cork’s blood cells mitochondrial CML patients, although the number of chromosomes is still 46, but there is a group of G in a special part of the missing long-arm marker chromosomes (so-called marker chromosomes, usually refers to a diseased individual cells, constitutively morphologically abnormal chromosomes). This marker chromosome belongs to No. 22, which is No. 22 dye
