In the crewmembers of four Salyut-6 long-term flights, enzyme excretory function of the gastro-intestinal tract was investigated. These studies included: gastric proenzyme, pepsinogen, and pancreatic enzymes, amylase and lipase, in blood and urine, trypsin in blood, intestinal enzymes, invertase and glycyl-L-leucine dipeptidase in feces, and lipids in feces. The results obtained demonstrated a correlation between changes in enzyme excretion and space flight duration and profile. After the 140- and 175-day flight the most marked changes in the digestive organs were seen; they manifested as a simultaneous increase in secretory function of the stomach and the pancreas. However, after the 185-day flight, in which advanced countermeasures were used, the above changes were less distinct.
对参与“礼炮6号”四次长期飞行任务的机组人员的胃肠道酶排泄功能进行了研究。这些研究包括：血液和尿液中的胃酶原、胃蛋白酶原、胰腺酶（淀粉酶和脂肪酶），血液中的胰蛋白酶，粪便中的肠道酶（转化酶和甘氨酰-L-亮氨酸二肽酶）以及粪便中的脂质。研究结果表明，酶排泄的变化与太空飞行的持续时间和飞行模式之间存在相关性。在140天和175天的飞行之后，消化器官出现了最明显的变化；表现为胃和胰腺的分泌功能同时增强。然而，在采用了先进对抗措施的185天飞行之后，上述变化不太明显。
