The functional activity of serotonin- and histaminergic systems was investigated during 120-day head-down tilt. Serotonin excretion was increased until test day 70 and histamine excretion throughout the entire study. At the final stage of exposure (test days 100-120) the serotonin content decreased. Return to the normal motor activity stimulated the function of serotonin- and histaminergic systems.
在为期120天的头低位倾斜期间，对血清素能和组胺能系统的功能活动进行了研究。血清素排泄量在试验第70天前增加，而组胺排泄量在整个研究过程中均增加。在暴露的最后阶段（试验第100 - 120天），血清素含量下降。恢复正常运动活动刺激了血清素能和组胺能系统的功能。
