Sympathico-adrenal activity of cosmonauts was studied before, during and after 211- and 237-day flights on the Salyut-7 station. During flight blood and urine samples were drawn, collected and stored using a Plasma-01 unit. Blood was withdrawn from two crewmembers on flight days 217-219 by the physician-cosmonaut and brought to the Earth in a frozen state. After the 211-day flight the sympathico-adrenal system showed stimulation of the hormonal component and inhibition of the transmitter component on the recovery day as well as activation of the transmitter component and metabolic changes during the subsequent recovery period. On days 217-219 of the 237-day flight blood catecholamines slightly increased while their renal excretion remained unchanged and their metabolite excretion decreased. All the parameters under study increased significantly during the recovery period. These observations give evidence that the sympathico-adrenal system was not activated on flight days 217-219 and was significantly stimulated during the recovery period after 211- and 237-day flights.
对在礼炮7号空间站进行211天和237天飞行的宇航员的交感肾上腺活动在飞行前、飞行期间和飞行后进行了研究。在飞行期间，使用Plasma-01装置采集、收集和储存血液及尿液样本。在飞行第217 - 219天，医师宇航员从两名机组人员身上采集血液，并以冷冻状态带回地球。在进行211天飞行后，交感肾上腺系统在恢复日显示出激素成分的刺激和递质成分的抑制，以及在随后的恢复期间递质成分的激活和代谢变化。在237天飞行的第217 - 219天，血液中的儿茶酚胺略有增加，而其肾脏排泄量保持不变，代谢物排泄量减少。在恢复期间，所有研究参数均显著增加。这些观察结果表明，交感肾上腺系统在飞行第217 - 219天未被激活，而在211天和237天飞行后的恢复期间受到显著刺激。
