The composition of the intestinal microflora of 12 cosmonauts was studied before and after space missions of varying duration. Changes in the intestinal microbial coenosis were found prelaunch. The pattern of changes did not vary with an increase in space flight duration. The use of special prophylactic measures exerted a positive effect on intestinal(More)
The cosmonauts P. I. Klimuk and V.I. Sevastyanov during their 63-day flight showed functional changes that were identical to those they demonstrated during their shorterterm flights. During the long-term mission they adapted to the weightless state better than previously. Post-flight medical examinations revealed no pathologies. The following functional(More)
The results of studies of the vestibular function and spatial perception function in crewmembers of long-term (96- and 140-day) space missions aboard Salyut-6 are presented. Similar changes and individual variations are revealed. All the cosmonauts have shown the following changes: increased reactivity of the otolith organ, decreased sensitivity of the(More)
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(More)
