与胃癌相关的几个量化掌褶纹特征的初步研究   总被引:1,自引:0,他引:1  
本文对几个与胃癌的发生具有相关性的掌褶纹特征量进行了提取, 并与对照组进行了对比, 用统计学t检验的方法分析后发现,胃癌患者双手手掌掌褶纹的ATD角、左右手三线与掌宽夹角及左右手a-b嵴线数(a-bRc)与正常对照组之间均存在统计学意义上的差异, 这些结论为后期构建与胃癌的发生具有相关性的皮纹特征量化指标体系提供了依据,也为临床对早期胃癌患者的筛查提供了皮纹学方面的支持。  相似文献

车轮虫齿体特征的量化及其种内种间系统发育的研究   总被引:2,自引:0,他引:2  
齿体特征是车轮虫物种鉴定的一个重要依据。本文首次提出一种齿体结构面积比例量化法,即通过对齿钩、齿锥、齿棘、齿体环各部分反口面观面积的测量,分别计算出前三者与所在齿体的面积比以及所有齿体总面积与齿体环的面积比,从而将齿体特征转换为量化指标依据所测量化值,采用相似性聚类法,我们首先探讨了显著车轮虫(Trichodina nobbillis chen,1963)的三个种群的亲缘关系,然后以劳牧小车轮虫(Trichodinella lomi Xu,Song & Warren,1999)为外类群,选择显著车轮虫(Trichodina nobillis chen,1963)、异齿车轮虫(Trichodina heterodentata Duncan,1977)、杜氏车轮虫(Trichodina dormergui Wallengren,1897)和Trchodina fahaka(Khaled A.S.Al-Rasheid,2000)为研究对象,对车轮虫种间亲缘关系进行了分析。结果表明,Pdr值可以有效地表现种群间的差异;同时还发现齿棘面积比例较高的杜氏车轮虫和异齿车轮虫进化较晚,而齿棘面积比例较低的显著车轮虫进化较早,并得出了齿棘越发达,车轮虫越进化这一结论,支持了徐奎栋等所提出的游走亚目六种基本齿型的进化顺序。这种量化研究方法不但可对车轮虫齿体的各部分结构以及它们之间的相互关系进行定量描述,而且还可以这些数据为基础对车轮虫种群间及物种间亲缘关系进行研究。  相似文献

Group size and composition of blue sheep (Pseudois nayaur) were studied in the Helan Mountains, Ningxia Autonomous Region from November to December 2003. We scanned mountain slopes with binoculars and observed with 20 - 60 x spotting-scope. A total of 310 herds of blue sheep and 1 336 individuals were observed during the study period. Blue sheep were frequently seen in small herds of 2 to 8 individuals, which represent 94.8% of total herds observed. Herds consisting of 9 individuals or more represented 5.2%. The largest herd we observed numbered 51 individuals. Mean group size was 4.2 individuals. Blue sheep herds can be divided into three types: male herds (composed solely of males), female herds (consisting of females with or without juveniles of both sexes), and mixed herds (including adult males, females, and subadults). Among the 310 herds, female herds were counted 150 times (48.4%}, mixed herds 154 times (49.7%), and male berds 6 times (1.9%) . Of 1 336 blue sheep classified by sex and age, adults, subadults and juveniles composed 64.1%, 20.8%, and 15.1% respectively. The female: male ratio of adults was 1:0.73. The ratio of adult females to juveniles was 1:0.56, which is higher than the ratio recorded in spring ( 1:0.43) or summer ( 1:0.44). The results showed that the Helan Mountains State Nature Reserve has succeed in protecting blue sheep.  相似文献

小鼠早期胚胎内细胞凋亡的一个量化模型   总被引:3,自引:0,他引:3  
凋亡是早期胚胎(八细胞阶段后,特别是桑椹胚至囊胚期)进入非线性发育期的最重要诱因和调节因素.本文利用双光子激光扫描显微术,获得小鼠植入前胚胎的三维荧光图像;然后建立量化模型,经过一定图像处理,统计了凋亡小体在胚胎内的三维空间分布,并为探索凋亡的动力学机制做出一些尝试.研究发现,胚胎内细胞凋亡现象绝大部分(70%)发生在滋养外胚层,且胚胎质心与几何中心的偏离在32细胞期前后出现台阶式跃迁,这和囊胚腔的出现导致胚胎细胞分布对称性破缺的理论预测一致.  相似文献

This article describes a detailed analysis of 125 tumor patientsπfingerprints and palm-prints using standard classification methods including control group, χ2 test , and one2sample K2S analysis. It was noted that there were differences in the occurrence of specific fingerprints and palm2prints between the patients and the control group, and that some of these features were strongly correlated. These observations provide a powerful theoretical basis for establishing a quantifiable dermatoglyphics feature index system using the patients and control group’s classification with interpretation through discriminant analysis.  相似文献

This article extracted and analyzed several palm-print characteristics that correlate with the occurrence of gastric cancer and compared these characteristics with those of the control group by T-test. The results showed that there were differences between the patients and the control group in the ATD-angle, angle between the third flexor line and handbreadth, a-bRc of hand palms. These observations provide a powerful theoretical basis for establishing a quantifiable dermatoglyphics feature index system having relation with gastric cancer, and give a strong support for using clinical screening of early patients.  相似文献

西藏1000例藏族肤纹参数的研究   总被引:7,自引:2,他引:7  
汪宪平  张海国 《遗传学报》1991,18(5):385-393
本文报道了西藏1000例藏族14项肤纹参数。藏族与汉族的肤纹参数接近,与美国明尼苏达州白人的差异较大;在与12个民族的对比中与哈尼族、汉族的差异较小,与维吾尔族差异较大;在不同的地区,与四川平武地区的藏族差异较小,与甘肃甘南地区的藏族差异较大。本文提示肤纹参数在不同人种、不同民族、甚至同一民族不同地区人群间均不可混用。  相似文献

Biological affinities between the three endogamous groups of marine fishermen of Puri are examined with the help of nine anthropometric measurements and 22 dermatoglyphic traits of fingers and palms. The results are interpreted in the light of their ethnic, geographical, and migrational backgrounds. Multiple discriminant analysis and Mahalanobis's generalized distances suggest higher discrimination of populations with reference to anthropometric traits as compared to that in dermatoglyphic variables. While the nature of interpopulation distances conforms to the geographic pattern in anthropometrics, no clear picture emerges in the dermatoglyphic distances supporting either ethnic or geographic evidence.  相似文献

A brief update of recent developments and trends in dermatoglyphic research is presented, based on a 1980–87 literature review. The discussed topics include anthropological, genetic, medical and developmental studies of the epidermal ridge patterns and flexion creases, including dermatoglyphic variability, new methodological and classification approaches, studies of nonhuman primates and of other experimental animals. Rather than an exhaustive survey of the existing literature, the purpose of this communication is to point out specific accomplishments, novel approaches, and emerging trends in various fields of dermatoglyphic research.  相似文献

The dermatoglyphies of i70 leukemie patients have been studied and eompared with 180 eontrols. It was found that Sydney lines of right hands were presented in 8. 81 3. 44% aeute lymphatie leukemia patients and only in 1. 87+0. 92% controls. The patients with C'M[. showed that the rate of simian line of the palmar was inereased. The indes of areh and whorl of the fingers is more higher in the patients of aeute leakemia than the normal. The rate of the palmar white line in leukemie patients is higher (64. 18±4. 14%) than the controls (38+3. 96%. P&lt;0. 01) . The widest point of the major three palmar ereases is positive (&gt;2. 5 mm) , whieh is more frequent than the eontrols (P&lt; 0. 01) . The tiny changs of dermatoglyphies of the leukemie patients showed that the genetie faetors may have an important role in the leukemie pathogenesis.  相似文献

Analysis of the dermatoglyphics of a sample of Kung Bushmen living in the Kalahari of north-east Namibia is presented, and the results are compared with those of other Bushmen studies. A high frequency of arches, a low ridge count, and high frequencies of pattern reduction forms, appear characteristic.  相似文献

I analyzed the finger prints of 59 male and 48 female unrelated Bengalis in a rehabilitation camp of Dacca, Bangladesh. The most common pattern type in the Bengalis was the ulnar loop (53%), then whorls (40%); arches (5%) and radial loops (2%) were the least common. Radial loops occurred most frequently on the index fingers. I have shown the arch/whorl, whorl/loop, and pattern intensity indices, and I have presented ridge counts by individual digits and by total digital ridge count. Digital dermatoglyphics in the male Bangladeshis were similar to previous findings in male Brahmins of Bengal. However, there were more whorls and arches, fewer loops, and a higher mean total digital ridge count in the female Bangladeshis than in female Brahmins.  相似文献

Fingerprints of 104 New Zealand Maori males and 98 females have been analyzed. Whorls are more abundant in females (55.0%) than in males (47.3%). The index of pattern intensity reveals a higher value in females (15.39) than in males (14.52). The bimanual differences both in males and females are not statistically significant for the occurrence of pattern on the digits of the right and left hands. The difference between the sexes in occurrence of patterns is not statistically significant. Incidences of actual symmetry on the homologous digits represented a mean of 78.8% in all subjects. The mean total ridge counts showed 161.7 in females and 159.6 in males, respectively. Thus, the Maori show greater affinities with the Mongoloids in quantitative dermatoglyphics  相似文献
