裕固族皮纹学初步研究

本文研究了甘肃裕固族青少年儿童346人的皮纹学特征,报道了斗、箕、弓各型指纹的频率,指纹指数,总指嵴数,a-b嵴数,通关手出现率,掌纹真实花样等8项皮纹学参数和主线止区的分布比例。并作了性别、手别、族别及人种间的比较。结果表明,裕固族既具有蒙古人种的皮纹特征,也有一些白种人的皮纹特点,这可能暗示着裕固族有白种人的血统。

肤纹学视野中的中华民族

肤纹是灵长目特有的性状,在包括人类在内的灵长目动物的手掌、脚跖面上,布满了组成各种图案的皮肤嵴纹。不难理解,肤纹学就是对指纹、掌纹和足纹的科学研究。     

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。

皮纹采集和鉴定方法的改进

作者分析了各种皮纹采集法的利弊,设计了茚三酮——味精颜色反应和圆筒滚印采集皮纹法。此法避免了油墨法污染手足的缺点和其他隐性皮纹显现法的不足,便于大规模调查。作者试用的炭精——透明胶带法,可采集清晰的趾纹印。在分析样本时,用体视显微镜代替传统的放大镜鉴定纹型、计数嵴纹和追踪主线终点,既避免了误差,又保护了视力,具有一定的推广价值。

冀南地区汉族人群皮纹分析

本文研究了冀南地区健康汉族医学生1020例(男性510人, 女性510人)的皮纹, 探讨了冀南地区正常汉族群体皮纹特点。结果发现: 冀南地区群体指纹频率顺序: 尺箕纹>斗形纹>弓形纹>桡箕纹; 十指指纹类型分布有显著差异; 两性斗形纹分布有显著差异; 两手弓形纹分布有差异但不显著; 指纹纹型分布有极高对称性; 同名指指纹组合频率排序为L/L>W/W>L/W>A/L>A/A>A/W; 五指的FRC有显著差别、两性的TFRC有差异, 但不显著; 两性T/I、III、IV的真实花样出现率有差异。因此, 本文认为指纹分布具有同型组合极高亲和性、异型组合不相容性; 皮纹发育形成主要受遗传因素控制, 也受性别影响; 冀南地区人群可能与山东省、辽宁省同属中国汉族北方群同一亚群。

Quantitative characterization of finger and palm dermatoglyphics in Bulgarians

In the present paper data on finger and palm ridge counts of both hands are reported from representative samples of healthy Bulgarian males and females. Dermatoglyphic prints from both hands of 2431 Bulgarians (1161 males and 1270 females) have been taken in 116 settlements all over the country. The investigated males and females were healthy, not related persons of Bulgarian origin. The results of finger and palm ridge counts include basic statistics and correlations between ridge counts on separate fingers and the correlations between ridge counts in separate interdigital areas. The results, presented together with data on other dermatoglyphic features elaborated and published till now by the same authors for representative samples of Bulgarian males and females, can serve for the set up of a detailed data basis of the dermatoglyphic status of the Bulgarian population. At the same time they could serve as a norm for clinical and medico-biological investigations with theoretical and scientific applied purposes.

Sexual dimorphism in dermatoglyphic traits and fluctuating asymmetry in Bulgarians from northeast Bulgaria

In parallel with the development of dermatoglyphics as a method of identification, data have been accumulated on the characteristics of fingerprints related to sex and ethnic origin which make up the statistical basis of this study. The aims of the present study are to determine phenotype variations in the asymmetry of dermatoglyphics in both sexes within the scope of the entire hand skin ridge system; to investigate correlations between the phenotypes; and, to assess the fluctuating asymmetry among the Bulgarian population from the region of northwest Bulgaria. The sample consists of 894 unrelated, clinically healthy individuals (480 females and 414 males) aged 18–50 years, who live in towns and villages in the northwest provinces.Finger and palmar prints were collected using rolled print (inked) method. Twenty dermatoglyphics variables of fingers and hands, separately for right and left hands and jointly for both hands, were statistically assessed. The material was processed by SPSS 12 software. The results of the present study show distinctive sexual differences. Higher values in males are recorded in finger ridge counts, the Furuhata and Cummins indices, the palm ridge counts and the overall ridge counts in all interdigital areas. Males have higher frequency values in patterns Hy, Th/III and Th/IV.     

Epidermal patterns of the hands and feet of the pygmy chimpanzee (Pan paniscus)

The characteristics of the epidermal ridge system were studied in a series of eighteen lesser or pygmy chimpanzees (Pan paniscus). The general ridge alignments are very similar to those of the chimpanzee (Pan troglodytes); Biegert ('61). On the average the pattern intensity (P.I.) of the palm configurations is considerably higher in the pygmy chimpanzee than in the chimpanzee, thus representing the highest total palm pattern intensity of all species of the Hominoidea. The sole configurations show parallel main results to those of the palm; however, the decreased sole pattern frequency of the pygmy chimpanzee is of a smaller predominance only as compared to the values of the other species of this superfamily. The preliminary data on the finger tip patterns, translated into P.I. values, are much higher than in chimpanzees and within the range of the mean values of gorillas (Brehme, '73), while those of the toes of pygmy chimpanzees seem to possess the lowest P.I. values of the African apes.

Ridge counts of plantar dermatoglyphic interdigital areas and the relation of their trends to the anatomical axis

Brahman and Bhangi, two endogamous groups of Hindu society, have been studied for ridge counts of plantar interdigital areas. No significant sexual difference, excepting a–b ridge count for Brahmans, was observed. Similarly, nonsignificant bilateral variation is exhibited. No ethnic variation is observed as regards the mean total a–b, b–c and c–d counts. The distribution of ridge counts can be correlated with the anatomical axis of the palm and sole. The palm (Pateria, '67) shows the minimum value for b–c and the sole for a–b. Therefore the minimal counts coincide with anatomical axes, corresponding to the common localization of syndactyly.

Fixed and random effects in the variation of the finger ridge count: a study of fragile-X families.

A maximum-likelihood scoring technique for analysis of pedigree data allows for the concurrent estimation of random and of fixed effects in a quantitative trait. We included both types of effects in genetic models, to study the sources of variation in finger ridge count in 54 large families affected with the fragile-X disorder. The fixed effects were represented by fragile X and sex, and the random effects by environmental and genetic variance. We found a significant effect of fragile X in the mean of the finger ridge count on the thumb (finger 1) and index finger (finger 2), which had the lowest heritability and a negligible nonadditive component of genetic variance. This was in contrast with ridge counts on fingers 3 and 4, which showed little fragile-X effect, but high heritability and a significant nonadditive component. A contrast in genetic properties for ridge counts on fingers 1 and 2, compared with these counts on the remaining three fingers, may be relevant to increased selection pressures on functions of the thumb and of the index finger in evolution of modern man. We have also demonstrated an important effect of fragile X in increasing the additive variance in covariance, especially between male pairs. These findings suggest that the effect of the fragile-X genotype in finger ridge count is additive and superimposed on the normal hereditary variations in this trait.
