The experiment was carried out in 15 rabbits. Three of them were control. The stress of the pelvis--head direction was obtained in a centrifuge of 1 m radius. Six animals were rotated for 1 min., the other six--til death, which came within 3--4,5 min. of the experiment. By methods of injection, clearing and measuring it was found that in the vessels of the sympathetic trunk congestion phenomena were first and foremost under effects of stresses of the caudo-cranial direction. Their intensity is in direct dependence on the duration of stress. In the 1st series (1 min.) a considerable congestion of venous blood in the cranial sympathetic ganglion was observed in 1 case, while in the 2nd series (3--4,5 min.) very drastic congestion phenomena, with an enlarged diameter, vein deformity and so on, were constantly noted. A support is given to literature data that such "negative" stresses are less endurable for animals, death comes soon, since the phase of relative compensation under given conditions is promptly changed for the phase of decompensation.
实验在15只兔子身上进行。其中3只为对照组。骨盆 - 头部方向的应力是在半径为1米的离心机中获得的。6只动物旋转1分钟，另外6只 - 直至死亡，死亡发生在实验开始后的3 - 4.5分钟内。通过注射、清理和测量的方法发现，在交感干血管中，充血现象首先主要是在尾 - 颅方向的应力作用下出现的。其强度与应力持续时间直接相关。在第一组（1分钟）中，1例观察到颅部交感神经节有相当程度的静脉血充血，而在第二组（3 - 4.5分钟）中，经常会注意到非常严重的充血现象，伴有静脉直径增大、静脉变形等。这支持了文献数据，即这种“负面”应力对动物来说更难以忍受，死亡很快就会到来，因为在给定条件下相对补偿阶段会迅速转变为失代偿阶段。
