Abstract

The morphometric analysis of the interphase chromatine structure of the hepatic cells nuclei was carried out on the automated TV installation for the quantitative analysis of images "IBAS-2" (by the OPTON firm, the FRG) according to 50 optical and geometric parameters during various periods (1.2 and 4 weeks) after the vagotomy operation. It is determined that upper-molecular organisation of chromatine undergoes the biggest changes one week after operation, and changes of granular component are more informative than changes of the nongranular component (with the difference 15-20%). It was also revealed that chromatine components differ in tinctorial properties, which are evidently dependent on physicochemical characteristics of the chromatine under various functional conditions of the cell. As a result of the correlation analysis the group of morphometric indices of chromatine structure was revealed, which are highly correlated with level of transcription activity of chromatine during various terms after denervation. The correlation quotient of these parameters is 0.85-0.97. The summing up: vagus denervation of the liver causes changes in the morphofunctional organisation of the chromatine.

摘要

在自动电视装置“IBAS - 2”(德国OPTON公司)上,根据50个光学和几何参数,对迷走神经切断术后不同时期(1周、2周和4周)的肝细胞细胞核间期染色质结构进行形态计量分析。结果表明,术后1周染色质的高分子组织发生的变化最大,颗粒成分的变化比非颗粒成分的变化更具信息价值(相差15% - 20%)。还发现染色质成分在染色特性上存在差异,这显然取决于细胞不同功能状态下染色质的物理化学特性。通过相关分析,揭示了一组染色质结构形态计量指标,它们与去神经后不同时期染色质的转录活性水平高度相关。这些参数的相关系数为0.85 - 0.97。总结:肝脏迷走神经切断术会导致染色质形态功能组织发生变化。
