Cosmos 1887 - Science overviewTwenty two groups of U.S. investigators participated in joint studies of ten male rats flown on the Cosmos 1887 biosatellite. A summary of these studies embracing skeletal muscle, bone, endocrine, neural, intestinal, metabolic, immunology, cardiac, and gonadal investigations is presented. Three general objectives of the rat experiments are outlined - verification of previous observations of the biological responses to microgravity; clarification of the effects of microgravity on both the tissues investigated and the measurements performed; and relation of biological responses to flight duration. It is concluded that the first objective is met fully and the second with a varying degree of success. The confounding effects of overshooting the designated landing site and delayed recovery of the animals largely precluded meeting the last objective. It is also noted that investigations were performed for the first time on brain and spinal cord enzymes, a neurotransmitter, transmitter receptors, hypothalamic regulatory factors, pineal metabolites, atrial granules, liver histology, and jejunal mitotic rate in spaceflight animals.
