Studies of the gastrointestinal tract in the Mars-500 project
The international crew of researchers held 520-day isolation from June 3, 2010 to November 4, 2011. It was the project Mars-500 — simulating manned flight to Mars.

The crew (photo by IBMP; left to right): Alexandr Egorovich Smoleevskiy (Russia) — physiologist, Romain Charles — (France) — flight engineer, Alexey Sergeyevich Sitev (Russia) — engineer and commander of the mission, Sukhrob Rustamovich Kamolov (Russia) — a doctor of the crew, Diego Urbina (Italy) — engineer, Wang Yue (China) — instructor at the China Astronaut Research and Training Center.

The crew of the Expedition Mars-500

Crew of the experimental facility simulating an interplanetary spacecraft, conducted a 24-hour study of electrical activity of different parts of the gastrointestinal tract (electrogastroenterography). For these studies, the Institute of Biomedical Problems of RAS, with the participation of the RPE Istok-Sistema based on the commercial acidogastroenterograph Gastroscan-GEM created an experimental model of the airborne gastroenterograph Splanhograph (for experiment Splanh). The board gastroenterograph Splanhograph in contrast to the acidogastroenteromonitor Gastroscan-GEM hadn't a pH channel.

The gastroenterography also is in satellite experiments of Mars-500. Photos about this are here.

The Coordinating Scientific and Technical Council of the Russian Federal Space Agency has included into the Program of scientific and applied research and experiments planned for the Russian segment of International Space Station in the section for Biomedical Research experiment the Splanh — a study of the structural-functional state of various parts of the gastrointestinal tract to detect specific changes in the digestive system in a space flight.

Not only astronauts are studied by gastrography, but ordinary patients may be to do this test for the diagnosis of functional disorders of his gastrointestinal tract in many leading gastroenterological centers in Russia. Photos of the study represented in the our photo archive.
