所有患者MTC核异染色质少于正常淋巴细胞，核仁范围在2-8μm之间；

The heterochromatin of MTC was less than that of normal T cell and nucleolus diameter was from 2 to 8 μ m in all cases .

结论疑有染色体异常个体的9号染色体异染色质区的变异率高于正常人4.2倍（P0.01），这说明9号染色体异染色质区的变异可能参与一些染色体病的发生。

Conclusion : The aberration rate of chromosome 9 heterochromatin is 4.2 times for persons suspected to have chromosome abnormalities higher than for normal individuals ( P0.01 ) . This study suggests that the aberration of chromosome 9 heterochromatin may contribute to chromosomal disease .
