智力残疾儿童的指(趾)端皮纹研究

Research on finger-end (toe-end) skin veins of children with mental deficiency

收集先天智力残疾儿童的指端弓形纹、桡侧箕形纹明显高于大学生组，而斗形纹低于大学生组，这三种纹理在两组中存在非常显著的差异（Ｐ＜０．０１）；而趾端纹理中，智残儿童组的弓形纹高于大学生组，胫侧箕和斗形纹低于大学生组，且差异均非常显著（Ｐ＜０．０１）。

Data about skin veins of children with mental deficiency and university student were collected for more than 10 years. Of them 90 subjects were randomly sampled for comparison and analysis of their veins of finger-end and toe-end.Results showed that the tinger end arch and radial loop of children with mental deficiency were obviously higher and whorl was lower than those of students;toe-end arch of chilren with mental deficiency was higher and libial loop and whorl were lower than those of students. There was a significant difference between the two groups about the three skin veins(P<0.01).
