太行山猕猴掌面肤纹嵴线的走向

Dermatoglyphics ridge line direction of the palms of Macaca mulatta

目的探讨太行山猕猴掌面肤纹嵴线走向特征。方法对52例(♀37例、♂15例)太行山猕猴(Macaca mulatta)掌面肤纹的嵴线走向进行调查,建立太行山猕猴掌面肤纹嵴线走向模型,并与日本猕猴进行比较。结果在种群水平上,太行山猕猴掌面指间Ⅱ区嵴线走向末端主要至2、5、6区,6区频率最高;掌面指间Ⅲ区嵴线走向末端主要结束于6区,掌面小鱼际角1区域嵴线多呈现12/4/2走向;掌面肤纹嵴线走向侧别之间差异没有显著性(P> 0. 05),为对称结构;雌雄性之间,掌面角1的嵴线走向差异具有显著性(P <0. 05),角7、角8嵴线走向性差不明显(P> 0. 05);太行山猕猴和两组日本猕猴(Macaca fuscata)掌面肤纹嵴线走向相互之间种属差异明显(P <0. 01)。结论猕猴肤纹的嵴线走向特征可以作为研究种属差异的一个指标。

Objective To determine the characteristics of dermatoglyphics ridge line direction of the palms of Taihang Macaca mulatta. Methods A total of 52（ 37 females and 15 males） Taihang Macaca mulatta were examined in this study. The model of dermatoglyphics ridge direction of the palms was established,and compared with Macaca fuscata.Results At the population level,in interdigitalⅡ,the end of dermatoglyphics ridge lines were mainly in area 2,5 and 6,and most frequently ended in area 6. In interdigital Ⅲ,dermatoglyphics ridge lines ended in area 6. In hypothenar 1,dermatoglyphics ridge lines were in 12/4/2 direction. There was no statistical difference when left and right palms（ P〉0. 05） were compared. The two sides were symmetrical. Significant difference was detected between female and male Macaca mulatta in ridge line direction of palm angle 1（ P〈0. 05）,but not in that of palm angle 7（ P〉0. 05） or Palm angle 8（ P〉0. 05）. The dermatoglyphics ridge line direction of palms showed significant difference between Taihang Macaca mulatta and Macaca fuscata（ P〈0. 01）. Conclusion Dermatoglyphics ridge line direction of the palms is one of the criteria characteristics to detect interspecific differences.
