Under study were effects of gravitation stresses, total hypokinesia and their combinations on blood vessels of the stomach. The work was carried out in 130 rabbits, 16 of them being used to study the normal structure of the gastric vascular bed. The vascular bed was injected with the Gerota's mass followed by clearing, making histological preparations and roentgenography. The investigation has revealed both quantitative and qualitative changes in the structure of the gastric blood vessels. The maximum endurable stress of the ventro-dorsal direction causes morphological shifts less pronounced than stresses of longitudinal directions. With prolonged terms of hypokinesia (1-12 weeks) morphological changes became more pronounced in all the layers of the stomach. A combination of successive gravitation stresses and hypokinesia during 4-12 weeks aggravated morphological changes which occurred after exposure to isolated above factors. The animals subjected to maximum endurable stresses before and after 4-week hypokinesia developed vascular changes more typical for the effects of gravitation. The pretraining of animals did not give a pronounced positive effect on the changes of the angioarchitectonics of all the gastric layers after a repeated stress following 4-week hypokinesia.
研究了重力应激、完全运动减少及其组合对胃血管的影响。该研究在130只兔子身上进行,其中16只用于研究胃血管床的正常结构。向血管床注入热罗塔氏液,随后进行清理、制作组织学标本和X射线摄影。研究揭示了胃血管结构的定量和定性变化。腹背方向的最大耐受应激引起的形态学变化不如纵向应激明显。随着运动减少期延长(1 - 12周),胃各层的形态学变化变得更加明显。连续4 - 12周的重力应激和运动减少相结合,加剧了在单独暴露于上述因素后出现的形态学变化。在4周运动减少前后承受最大耐受应激的动物,其血管变化更典型地表现为重力作用的影响。在4周运动减少后重复应激时,动物的预先训练对胃各层血管构筑的变化没有产生明显的积极影响。
