| 1. | Objective : to explore the correlatitiy between mental retardation , chromosome aberrtion rate and fragile site expression rate
目的：探讨精神发育迟滞者与染色体畸变率和脆性部位表达率的相关性。 |
| 2. | Conclusion : the mental retardation is correlative with the chromosome aberration and the fragile site expression rate
结论：提示精神发育迟滞与染色体的畸变率和脆性部位的表达率有一定的相关性。 |
| 3. | A significant difference of the expression rate of telomerase activity was found between carcinoma and tumor - adjacent tissue ( p < 0 . 05 )
端粒酶活性表达与食管癌病人的性别，民族，肿瘤部位，分化程度，有无淋巴结转移等似乎无关。 |
| 4. | Methods : using the peripheral blood lymphocyte chromosome preparation technique and fragile site technique , to analyze chromosome aberrtion rate and fragile site expression rate of 30 cases of mental retardation sufferer and 30 cases of normal person respectively
方法：采用外周血淋巴细胞染色[摘要]目的：探讨精神发育迟滞者与染色体畸变率和脆性部位表达率的相关性。 |
| 5. | About the control group , the chromosome aberration rate of is 1 . 55 % ; the fragile site expression rate is 0 . 89 % . both the chromosome aberration rate and the fragile site expression rate of two groups are distinct from each other ( p 0 . 01 )
结果：精神发育迟滞者染色体的畸变率为4 . 32 ，脆性部位的表达率为2 . 18 % ，而正常对照组染色体畸变率为1 . 55 ，脆性部位的表达率为0 . 89 ，两者的染色体畸变率和脆性部位表达率有明显的差异( p 0 . 01 ) 。 |
