Laboratory mice who spent only two weeks in orbit show early signs of liver problems upon returning to Earth, raising concerns about the possible consequences for man a long stay in space, researchers said in a study released Wednesday.
NASA and studies the long-term effects of space travel on the human body and recently sent one of its veteran astronauts, Scott Kelly, on a mission of 340 days in the International Space Station (ISS) , along with a Russian cosmonaut.
“Before this study we did not have much information about the impact of space travel on the liver, “said Karen Jonscher, lead author of the study, associate professor of anesthesiology and health of Anschutz medical Campus of the University of Colorado.
” we knew astronauts frequently return with symptoms of diabetes, but are usually resolved quickly, “he added
the mice spent 13 and a half days aboard the shuttle Atlantis in 2011. after which the researchers found the development of some cells that can damage the liver long term, increased fat in the body and indicators of early fibrosis.
“If a mouse shows increasing signs of fibrosis without a change in diet 13.5 days, what it can happen to man? “asked Jonscher.
” If this is a problem or not is an open question, “he added. Research is reproduced in the journal PLOS ONE
