在正常叶酸和低叶酸两种培养条件下,作者对两个家族性多发性结肠息肉家系中的30名成员的外周血淋巴细胞进行了较全面的染色体分析,发现低叶酸培养条件下,绝大多数家族性多发性结肠息肉患者外周血染色体结构畸变率明显升高,平均达10%。患者中出现频率较高的脆性部位有3p14、1p22、1p32等。
Under normal folic acid and low folic acid conditions, the authors performed a more complete chromosomal analysis of the peripheral blood lymphocytes of 30 members of two familial multiple colonic polyp families and found that under conditions of low folate culture, The majority of familial multiple colorectal polyps in patients with peripheral blood chromosome aberrations significantly increased, an average of 10%. Patients with higher frequency of brittle parts have 3p14, 1p22, 1p32 and so on.
