title: [Changes in rats' pain sensitivity reaction after 21-day suspension].
abstract: In an experiment with 21-d suspension rats were found to increase reliably the threshold of pain sensitivity to thermal stress. It was hypothesized that the major mechanism of these changes is stress-induced analgesia as a result of increased hormonal secretion by the end member of the hypothalamo-pituitary-adrenal axis.
