细胞遗传学在临床应用已日益广泛,近年来我科开展外周血淋巴细胞培养及染色体G显带,发现染色体异常15例。报道如下。 1 资料来源 妇产科门诊9例、小儿科4例、泌尿科2例。 2 染色体核型检查 取外周血淋巴细胞培养及G显带。各计数30～60个分裂相,镜下分析至少3个细胞核型。15例染色体异常核型(见附表)。4例典型染色体异常核型(见封四图1～4)。 Cytogenetics has become increasingly widespread in clinical practice. In recent years, our department has conducted peripheral blood lymphocyte culture and chromosome G banding, and found 15 cases of chromosomal abnormalities. Reported as follows. 1 Source Obstetrics and Gynecology clinic in 9 cases, 4 cases of pediatrics, urology in 2 cases. 2 karyotype examination of peripheral blood lymphocytes and G banding. Each count 30 ~ 60 split phase, microscopic analysis of at least 3 cell karyotype. 15 cases of chromosomal abnormal karyotype (see Schedule). 4 cases of typical chromosomal abnormal karyotypes (see Feng four Figure 1 ~ 4).
