| 内容記述 | Tissues of male, specific pathogen-free Wistar rats flown on the Cosmos 1887 biosatellite are studied. First the mission is described, and then analytical methods are outlined. It is noted that flight rats grew more slowly and had larger adrenal glands than earth gravity controls. Analysis of plasma reveals increased concentrations of hepatic alkaline phosphatase, glucose, urea nitrogen, and creatinine in flight rats. In contrast, electrolytes, total protein, albumin, corticosteron, prolactin, and immunoreactive growth hormone levels are unchanged. However, testosterone concentration is marginally decreased after flight and thyroid hormone levels are suggestive of reduced thyroid function. |
