摘    要:
目的 研究300名正常白族人指嵴纹数和t三叉,为医学、遗传学、人类学提供正常参数.方法 在知情同意手续下,捺印调查对象的手纹.结果 总指嵴纹数(TFRC)为126.88±32.28,男性大于女性(P<0.05),无手别差异(P>0.05).各指指嵴纹数(FRC)高低为:拇指>环指>食指>中指>小指,均为男性大于女性(P<0.05),无手别差异(P>0.05).对应指FRC差值变化趋势为,随着差值增加频数逐渐减少,绝大部分差值在3以内(占88.2%).TFRC的频数分布近似正态分布.atd角为(40.27±4.34)度,tPD为(12.46±4.66)%,均为女性大于男性(P<0.05),无手别差异(P>0.05).72.5%的个体tPD低于15%,无大于30%的.结论 对应指FRC和t三叉的分布具有对称性,白族和其他民族有共性也有其特异性.

关 键 词:肤纹学  指嵴纹数  t三叉  白族

Abstract:
Objective To study the finger ridge counts and t triangle on 300 normal people of Bai nationality,and to provide normal parameters for medicine,genetics and anthropology. Methods The ink print of fingerprints and palmar patterns were obtained with informed consent. Results The average value of TFRC was 126.88±32.28,which had a significant difference between males and females(P<0.05),but had no significant difference between left and right hands(P>0.05).Comparing the mean value of FRC on each finger,the order was that:the value of thumb>of ring finger>of index finger>of middle finger>of little finger.And the mean value of each finger had a significant difference between males and females(P<0.05),but had no significant difference between left and right hands(P>0.05).Along with the increasing deviation value of FRC between corresponding fingers,the variety trend of the frequency was gradually reducing,and an overwhelming majority(88.2%) of the value was less than or equal to 3.The frequency distribution of TFRC was close to a normal distribution.The mean value of atd angle was 40.27±4.34 and that of tPD (12.46±4.66)%.Both of atd angle and tPD had a significant difference between males and females(P<0.05),but had no significant difference between left and right hands(P>0.05).The frequency of tPD under 15% was 72.5%,and none was over 30%.Conclusion The distribution of FRC and triangle in corresponding fingers of Bai nationality is symmetric and it shares some common features with that of other ethnic groups with its own characteristics.
Keywords:Dermatoglyphics  Finger ridge count  t Triangle  Bai nationality
