广西京族女中学生掌纹特征分析

目的:分析广西京族女中学生掌纹特征,以提供该民族女中学生人类学体质参数及肤纹学参数。方法:取京族女中学生掌印资料114份。分析a-b纹嵴计数(a-bridge count,a-bRC)、轴三叉位置(the axial triradius)、手掌主线(palmar main lines)走向、手掌纹型(palmar patterns)及手掌主要屈褶(palmar major flexion creases)等5个项目,并与国内其他5个民族的掌纹文献资料数据进行对比分析。结果:京族女性左、右手a-bRC差异有统计学意义(P<0.05),并与所比民族差异均有统计学意义;京族女性的轴三叉(t)位置仅与广西仫佬族有显著性差异,靠近手掌腕部,与所比民族差异无统计学意义(P>0.05);追踪手掌主线提示,京族女性右手掌纹嵴比左手掌纹嵴更趋横行走向;手掌纹型出现频率最高者为Th/I1(Thenar/interdigitalⅠ)区,出现频率最低者为第2指间区I2(interdigitalⅡ,I2)区,且与所比民族差异均有统计学意义(P<0.05);5种掌褶类型出现频率,京族与所比部分民族差异存在统计学意义(P<0.05)。结论:广西京族女性的掌纹具有本民族一定特点。

Features of the palmar dermatoglyphics of Gin nationality female students in Guangxi

Objective：To analyze the features of the palmar dermatoglyphics and provide the ethnologic and anthropological parameter data of Gin nationality female students in Guangxi.Methods：The palmar print data from 114 female students of Gin were collected.the a-b ridge count（a-bRC）,the positions of the axial triradius,the trend of palmar main lines,the palmar patterns and the palmar major flexion creases of the palmar prints were analyzed and compared with the literature data of 5 nationalities in China.Results：The a-bRC between the left and right hands of Gin showed significantly different and had distinct differences from those of other compared nationalities（P〈0.05）,the positions of the axial triradius of Gin were more close to the wrist of their palm without significant difference from other compared nationalities（P〉0.05）.The direction of the palmar ridge of the right hand was more horizontal than the left one.The highest frequency of palmar patterns of Gin all appeared in Th/I_1 area,and lowest in I_2 area which were significantly different from those of other compared nationalities（P〈0.05）.There were differences in frequencies of 5 types of palmar major flexion creases among Gin and others.Conclusions：The features of the palmar dermatoglyphics of Gin nationality in Guangxi region are specific.
