Preflight the rhesus-monkey Bion was implanted with sensors and transducers to measure blood pressure and linear flow velocity in the common carotid artery and to compare these parameters with central circulation. At the early flight stage blood pressure increased, blood flow decreased and resistance in the area grew. The last change can be regarded as a compensatory reaction that can provide rapid adaptation of regional circulation to changes in systemic circulation. At later flight stages blood pressure showed distinct circadian oscillations and blood flow, a significant increase when compared to the ground-based 36-hour control study. Regulatory mechanisms of the cardiovascular system changed to the greatest extent on flight day 2. This manifested as a decrease of the amplitude of circadian oscillations of the above circulation parameters. Signs of cardiovascular adaptation to the effects of microgravity were discerned on flight days 3 to 5.
对恒河猴“比昂”进行飞行前准备时，在其体内植入了传感器和换能器，以测量颈总动脉的血压和线性流速，并将这些参数与中心循环进行比较。在飞行早期阶段，血压升高，血流量减少，该区域的阻力增大。最后一个变化可被视为一种代偿反应，它能够使局部循环迅速适应体循环的变化。在飞行后期阶段，血压出现明显的昼夜节律振荡，血流量与地面36小时对照研究相比显著增加。心血管系统的调节机制在飞行第2天变化最大。这表现为上述循环参数的昼夜节律振荡幅度减小。在飞行第3至5天可看出心血管系统对微重力影响的适应迹象。
