摘要
皮纹是人体稳定的体表特征.它的各种性状具有遗传特征,种族差异和民族差异,并且在刑侦及其某些遗传性疾病的诊断中起重要作用.为积累我国各民族正常群体的皮纹学参数值,为人类学、遗传学及临床医学等相关研究提供正常对照数据,我们对416例湘西苗族学生的手纹进行了研究,为了对照分析,引用了有关文献.
Students of Miao nationality in Xiangxi have been observed and analyzed in 416 (male 270, female 146) individuals forfingerprints and palmar-prints. The ages of the individuals range from 12 to 20 years.
The results of the study are summarized as follows. (l)The frequeneies of finger patterns arch, ulnar loop, radial loop,whorl: of males 4.15%, 46.11%, 4.78%, 44.96%; and the females 4.25%, 49.45%, 3.29%, 43.01%. (2) The mean total finger ridge count (TFRC)is 138.07±?9.76 in males and 131.78±39.16 in females. (3) The mean a-b total ridge count is 36.42±4.74 in males and 35.70±4.24 in females. The mean a-bRC is 36.17±4.58 in both sexes. (4)The mean atd angle is 40.86°±4.21 in males and 42.36°±4.05 in females. The mean atd angle is 41.39±3.39 in both sexes. The mean tpD is 15.55±5.84% i n males and 15.91 ±5.32% in females. The mean tPD is lo.67±5.66% in both sexes. (5) Frequency of persons with Simple crease is 4.21%. (6) Frequencies of thenar true patterns are respectively 7.41% and 3.77% in males and females. Frequencies of hypothenar true patterns are respectively 15.74% and 20.21% in males and females. Frequencies of true patterns in palmar interdigital areas I2., I3 and I4 are respectively 3.15%, 17.22% and 62.78% in males and 0.68%, 13.36% and 62.67% in females.
Above data are compared with of the Han nationalit' and 10 Chinese nationanl minorities, the differences in part items statistically were significant or highly significant.
