In acute experiments on cats, responses of the resistance and capacity vessels of small intestine, spleen, kidneys, and m. gastrocnemius were studied during pressor sinocarotid reflex and electrical stimulation of the sciatic and brachial afferents. It was shown that, against the background of constrictory responses of the resistance vessels in these organs, both the constrictory and the dilatory responses of the capicitance vessels could occur or not. Correlation analysis revealed no dependence between the markedness and character of the capacitance vessel responses and the changes of the venous blood oxygenation during pressor reflexes. The regulatory mechanisms determining, different characters of the capacitance vessels during neurogenic effects and the methodical conditions revealing the true nature of changes occurring in the postcapillary bed, are discussed.
在对猫进行的急性实验中，研究了在颈动脉窦加压反射以及坐骨神经和臂丛传入神经电刺激期间，小肠、脾脏、肾脏和腓肠肌的阻力血管和容量血管的反应。结果表明，在这些器官阻力血管出现收缩反应的背景下，容量血管的收缩和舒张反应都可能出现或不出现。相关性分析显示，在加压反射期间，容量血管反应的显著程度和特征与静脉血氧合变化之间没有相关性。本文讨论了决定神经源性效应期间容量血管不同特征的调节机制，以及揭示毛细血管后床发生变化真实性质的方法学条件。
