摘要

到目前为止,痣的起源和发展的多因素性质一直是争论的主题。理解这一过程并得到这个问题答案的一种方法是使用宪法研究方法。本研究的目的是建立和分析男性良性痣发生可能性的判别模型,这取决于身体的结构和大小特征。22 - 35岁乌克兰男性良性痣(34例为黑色素细胞良性单纯性痣;黑素细胞良性发育不良痣27例;黑色素细胞良性先天性痣14例;根据Bunak V. V.(1941)的方案确定人体测量指标,根据Heath-Carter方案(1990)确定体型成分,根据Matejko公式(1921)确定体重成分组成指标。对照组选取文尼茨亚国立皮罗戈夫纪念医科大学研究中心数据库中82名同年龄组实际健康男性的人体测量学和体型指标。判别分析在授权统计软件包“Statistica 5.5”中进行。通过判别分析,建立了基于人体测量学和躯体型指标特征的良性痣发生可能性的可靠模型。结果发现,男性健康患者与良性痣患者能够可靠地解释所获得的健康与患病、单纯黑素细胞或发育不良痣患者与其他组良性痣之间的分类指标(判别功能占75.7%;Wilks’Lambda统计量=0.125;р< 0.001)。在良性痣组之间,所获得的分类指标只有在单纯性黑素细胞或发育不良痣患者与先天性黑素细胞或非黑素细胞痣患者之间才有可能得到可靠的解释(判别功能占48.4%;Wilks λ统计量=0.662;然而,所有人类学变量的总体几乎没有差别。健康男性和患病男性的模型包括:皮褶厚度(42.8%)、腰围(28.6%)、肩宽和体型的自构成分(14.3%);在有良性痣的男性中,只有身体的周长大小。在健康男性和患病男性模型中,造成歧视的最大因素是上部前臂的周长、肩部的宽度和侧面的皮褶厚度;而良性痣患者胸围上吸气。结果表明,环境因素对良性痣的发生有显著影响。

Discriminant models of the possibility of benign nevi occurrence and features in men depending on the characteristics of anthropo-somatotypological indicators
The multifactorial nature of the origin and development of nevi is the subject of debate so far. One way to understand this process and get an answer to this question is to use a constitutional method of research. The purpose of the study is to build and analyze discriminant models of benign nevi occurrence possibility in men depending on the characteristics of the structure and size of the body. For Ukrainian men aged 22 to 35 years with benign nevi (34 with melanocyte benign simple nevi; 27 with melanocyte benign dysplastic nevi; 14 with melanocyte benign congenital nevi; 17 with nonmelanocyte benign nevus) determined anthropometric indicators according to the scheme of Bunak V. V. (1941), components of the somatotype according to the Heath-Carter scheme (1990), as well as indicators of the component composition of body weight according to Matejko formulas (1921). The control group consisted of anthropometric and somatotypological indicators of 82 practically healthy men of the same age group selected from the data bank of the Research Center of National Pirogov Memorial Medical University, Vinnytsya. Discriminant analysis was performed in the licensed statistical package “Statistica 5.5”. With the help of discriminant analysis, reliable models of the possibility of benign nevi depending on the characteristics of anthropometric and somatotypological indicators are built. It was found that healthy and patients with benign nevi of men can reliably interpret the obtained classification indicators between healthy and sick, and between patients with melanocyte simple or dysplastic nevi and other groups of benign nevi (discriminant function covers 75.7 % of cases; Wilks' Lambda statistics=0.125; р<0.001). Between groups of benign nevi, reliable interpretation of the obtained classification indicators is possible only between patients with melanocyte simple or dysplastic nevi and melanocyte congenital or non-melanocyte nevi (discriminant function covers 48.4 % of cases; Wilks' Lambda statistics=0.662; р<0.001), however, the totality of all anthropological variables has little discrimination. The models of healthy and sick men include the skinfold thickness (42.8 %), girth sizes (28.6 %), shoulder width and endomorphic component of the somatotype (14.3 % each); and among men with benign nevi, only girth sizes of the body. The greatest contribution to discrimination in models of healthy and sick men is made by the circumference of the forearm at the top, the width of the shoulders and the skinfold thickness on the side; and among patients with benign nevi – chest girth on inspiration. The obtained results indicate a significant influence of environmental factors on the occurrence of benign nevi.
