抑郁症患者的皮纹特征

采用体质测量法以天津汉族正常者310例(女性231例, 男性79例)为对照, 分析天津汉族抑郁症患者202例(女性140例, 男性62例)的皮纹特征。经统计学分析, 结果显示: 抑郁症患者组双手a-b嵴线数、小鱼际及各指间区真实花纹出现率较正常组无显著性差异; 指端斗形纹出现率增加(P<0.01); 掌部a-b嵴线数波动不对称性(FA值)增加(P<0.01)、atd角偏大(P<0.01)、桥贯型及皱褶掌出现率增加(P<0.01)等可能是抑郁症患者的主要皮纹特征。     

Palmar dermatoglyphics of dyslexia

Palmar dermatoglyphic prints were taken of 261 dyslexics (173 males and 88 females) and compared against those of 707 controls (372 males and 335 females). Dyslexics of both sexes were found to exhibit greater complexity in terms of ridge count and pattern location than controls, particularly on the left hand. Specifically, both male and female dyslexics exhibited higher left a-b counts, wider atd angles on both palms, and higher frequencies of pattern in left interdigital area IV. Additionally, male dyslexics also had higher right a-b counts and greater frequency of pattern in the left hypothenar area. Dyslexics of both sexes were also found to have more distally located axial triradii, and investigation of bilateral asymmetry found dyslexics to exhibit more directional asymmetry than controls in the variable of a-b count, with the left value for both groups being greater than the right. It was concluded that the study evidenced strong support for the hypothesis that some causative factor relating to the development of dyslexia is operating during the time period in which dermatoglyphic features are formed. The relevance of these findings in terms of the Geschwind hypothesis and the possible importance of prenatal testosterone are discussed.     

Topological description of Easter Islander palmar dermatoglyphics

A sample of 594 Easter Islander palms was analyzed according to the topological method. Some suggestions for clarification of the topological approach were made, including clearer definition of the palmar triradii and substitution of the term "profile" for "formula." The frequency of Easter Islander profiles was compared against British and Australian Aborigine samples (Loesch, 1974; 1983a,b) and found to be significantly different for two of the ten most common combinations. The individual pattern elements, pattern intensities, a-b count, A-line exit, and atd angle were described, with population comparisons made when they were available.

A dermatoglyphic study of the Kavalan aboriginal population of Taiwan

By the 1970s, a number of dermatoglyphic studies of Taiwan aborigines (Gaoshan nationality) had been published, however in each only a few dermatoglyphic variables were addressed. Since that time, little new research has been conducted. In this study, we collected and analyzed the dermatoglyphs of 100 individuals of Kavalan, a Taiwan aboriginal population, and we reported a wide range of dermatoglyphic variables including total finger ridge count (TFRC), a-b total ridge count (a-b RC), atd angle and axial triradius percent distance (tPD), and frequencies of fingerprint pattern, palmar thenar pattern, palmar interdigital pattern, palmar hypothenar pattern, and simian line. This study is the first comprehensive dermatoglyphic research of any Taiwan aboriginal population.

Congenital cleft lip and fluctuating dermatoglyphic asymmetry.

Fluctuating asymmetry for the palmar atd angle was studied in propositi born with CL(P) and their normal parents and sibs. The propositi with a family history of this congenital malformation were significantly different from the controls for this type of asymmetry. The propositi without a family history and the normal parents and sibs of both types of propositi were similar to the controls. The difference between the two types of propositi suggests that in some individuals a genetic mechanism may account for CL(P) and increased fluctuating asymmetry for this dermatoglyphic trait.     

A family study of dermatoglyphic traits in India: segregation analysis of accessory palmar triradii and the atd angle

Accessory triradii and the atd angle were examined via complex segregation analysis in order to evaluate possible genetic effects on these dermatoglyphic traits, measured in an endogamous Brahmin caste of peninsular India. The phenotypes considered included: presence of accessory palmar triradii a' and d', associated with the interdigital areas II and IV, respectively; presence of an accessory axial triradius tt' associated with the proximal margin of the palm; and an arctanh-transformation of the atd angle measurement. For all accessory triradii considered in the present investigation familial resemblance was evident. The most parsimonious model which could account for the observed resemblance was a multifactorial model that includes polygenic effects as well as transmissible environmental effects that are inherited in the same pattern as polygenes. Evidence of familial resemblance was also found for the arctanh-transformed atd angle, which could be attributed, initially, to both a major effect and a multifactorial component. Tests of transmission of a putative major gene were performed which yielded results consistent with Mendelian transmission, although an alternative test of no transmission of the major effect also fit the data. In light of these contrasting results we are precluded from accepting with confidence the notion of a major gene influence on the atd angle. We have concluded that the accessory triradii a', d', and tt', and the atd angle are influenced by multifactorial effects, including additive polygenes and possible environmental factors, such as intrauterine effects.     

A dermatoglyphic study of the Amis aboriginal population of Taiwan

Amis is the largest aboriginal population in Taiwan. The previous dermatoglyphic studies of the Amis only reported limited data. In this study, we collected and analyzed the dermatoglyphs of 200 Amis individuals, and we reported a wide range of dermatoglyphic variables including total finger ridge count, a-b ridge count, atd angle, axial triradius percent distance, and frequencies of fingerprint pattern, palmar thenar pattern, palmar interdigital pattern, and simian line. This study is the first comprehensive dermatoglyphic research of Amis since 1960s, and its dermatoglyphic data will be useful for future research in anthropology, genetics and medicine.

Variation in maximal angle <atd among 20 Dhangar castes of Maharashtra,India

In a sample of 3000 males belonging 20 endogamous castes from Maharashtra were analysed to determine specifically the distribution of <atd along with bilateral differences and population variation. The right, left and right plus left sides, each separately exhibit unimodal, meptokurtic and positively skewed distribution in all populations. The mean and standard deviations are significantly heterogenous in nature. Non-significant bilateral differences of atd angle toward symmetry express well in all 20 castes. Population variations are found to be lesser, i.e. 44 (23.16%) significant out of 190 caste pairs compared to other palmar quantitative variables like interdigital ridge counts — ab, bc and cd; and main line index. These results suggests, angle atd is more stable phenotype compared to some other palmar quantitative characters.

Dermatoglyphic characters and physique: A correlation study

The association of anthropometrics, particularly hand measurements, with dermatoglyphic characters is quantified. Children with square hands exhibit higher main line indices, a-b ridge counts, and more open atd angles. Adults with broader hands have more arches. Taller individuals with larger hands present higher a-b ridge counts and leaner subjects with long narrow hands, closer atd angles. The correlation of physique and dermatoglyphics is small but if verified, suggests that at early fetal stages, factors responsible for the establishment of dermatoglyphic patterns interact with genetic determinants of adult shape that are already active.
