广东汉族的皮纹密度分析

为获得广东汉族皮纹密度的基本参数, 在知情同意原则基础上采集18—21岁在校学生掌纹307例(男157人,女150人), 体视显微镜下测量掌纹嵴线, 计算皮纹密度。结果表明a-bRC、b-cRC、c-dRC、a-dRC和t-dRC分别是36.19±5.58、25.86±5.21、32.83±5.57、75.43±13.11和90.66±13.50,除c-dRC外,都是男>女。a-bDD、b-cDD、c-dDD、a-dDD、t-dDD和ΔatdDD分别是16.76±1.98、17.68±2.39、16.89±1.85、14.49±2.24、14.42±1.67和5.54±0.75,均为女>男。广东汉族皮纹密度与江西汉族和西藏藏族有一定差异。广东汉族皮纹密度有自己的特点, 这与民族渊源和生活环境的差异有关。

An Analysis of Dermatoglyphics Density of the Han Nationality from Guangdong

The purpose of this research was to obtain the basic parameters in the density of dermatoglyphics of the Han nationality in Guangdong. With informed consent, ink prints of the palmar patterns of 307 health students aged 18-21 years (157 males and 150 females) were collected. Palmar ridge counts were measured by stereomicroscope and the density of dermatoglyphics was calculated with the following results: a-bRC (36.19 ± 5.58), b-cRC (25. 86 ± 5. 21), c-dRC (32. 83 ± 5. 57), a-dRC (75. 43 ± 13. 11) and t-dRC (90. 66 ± 13. 50). Males are higher than females except for the following characteristics: c-dRC, a-bDD, b-cDD, c-dDD, a-dDD, t-dDD and △atdDD are 16. 76 ± 1. 98, 17. 68 ± 2. 39, 16. 89 ± 1. 85, 14. 49 ± 2. 24, 14. 42 ± 1. 67 and 5. 54 ± 0. 75 respectively. Females were all higher than males. The results of this work showed dermatoglyphic differences between the Han nationalities of Guangdong and Jianxi, with the Tibetan people in Tibet. The density of dermatoglyphics in the Han nationality in Guangdong have their own features, but with the general characteristics of Mongoloids. These feature to colonial origin and difference of habitat.
