Abstract

Adult rats underwent a simulated weightlessness for 10 days by being confined within a jacket attached to the chains hanging from the corners of a cage. When the suspended rats had free access to diet they consumed less and showed a decreased jejunal mucosal weight. However, thespecific activities (per mg of protein) of jejunal disaccharidases inthe suspended rats were similar to those of normal rats fed ad libitum. When the suspended rats were force fed the regular amounts of diet,they again showed relatively high jejunal disaccharidase activities, the levels of which were similar to those of pair-fed control animals. In contrast, the liver glycogen contents were remarkably decreased inthe suspended rats, regardless of whether they consumed sufficient amounts of diet. These results suggest that the digestive capability of carbohydrates is unaffected by the stress induced by the simulated weightless condition adopted in the present study, whereas hepatic glycogen metabolism is greatly altered in the simulated weightless condition.
