The aim of the investigation was to appreciate quantitatively the degree of endothelial heteromorphy and its spatial organization according to some indices allowing morphofunctional interpretation of their importance. Endothelium of the rabbit protal and jugular veins was studied in the flat film preparations along the length of 16--20 mm continuously. To elucidate changeability in tissue state, autocorrelative function was calculated with the following determination of spectral density. The latter makes it possible to reveal the presence of a monotonous trend and rhythmicity in vessel structure. Spectral analysis demonstrated that in different parts of endothelium the indices involved varied in their character. The parameters reflecting cell histophysiology are characterized by a marked monotonous trend. The parameters influenced by hemodynamic conditions change rhythmically. Nearly all the indices in the portal vein, evidently because of its peculiar physiological conditions, distinguish themselves by their more complex spectral composition than those of the jugular vein. The quantitative data obtained support heteromorphic character of endothelium and demonstrate that physiology and hemodynamics of the vessel are responsible for its degree of significance as there is a constant interrelation between the vessel and blood.
本研究的目的是根据一些能够对其重要性进行形态功能解释的指标，定量评估内皮细胞异形性的程度及其空间组织。在连续16 - 20毫米长的平片标本中，对兔门静脉和颈静脉的内皮进行了研究。为了阐明组织状态的可变性，计算了自相关函数，并随后测定了谱密度。后者能够揭示血管结构中单调趋势和节律性的存在。频谱分析表明，在内皮的不同部位，所涉及的指标在特征上有所不同。反映细胞组织生理学的参数具有明显的单调趋势。受血流动力学条件影响的参数呈节律性变化。显然由于其特殊的生理条件，门静脉中的几乎所有指标都具有比颈静脉更为复杂的频谱组成。所获得的定量数据支持内皮细胞的异形特征，并表明血管的生理学和血流动力学决定了其重要程度，因为血管与血液之间存在着持续的相互关系。
