(A)
Space travel is certainly bad for astronauts’bones，reducing their bone density(密度)after only a month of weightlessness，according to French research published on Friday.
Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity (微重力)，after their study of 1 5 astronauts from the Russian MIR station showed bone loss continued throughout space flights.“Bone loss was especially striking in four astronauts，”the scientists reported in the Lancet Medical Journal.
They measured the bone mineral density(BMD)of bones in the forearm(前臂)and lower
leg of the astronauts who had spent one to six months in space.The BMD loss was serious in the tibia(胫骨)of the lower leg，a weight—bearing bone，but hardly changed in the radius(桡骨)of the forearm.“Our results show the need to test not only different bones，but also different areas of the same bone since not all sites of the skeleton(骨架)are similarly affected by space conditions，”they added.
