Plasma corticosterone levels during repeated presentation of two intensities of restraint stress: chronic stress and habituation

Abstract

This study measured plasma corticosterone levels in male rats during repeated daily presentations of two intensities of restraint stress. The corticosterone response to a stress session was defined as the change from pre-stress levels to levels after 60 minutes of restraint. With the relatively intense stress imposed by four limb prone restraint, the corticosterone response partially habituated over seven days due to increasing basal corticosterone levels. However, even on day 7, there was still a large corticosterone response. With the milder stress of immobilization in a tube, the corticosterone response did not habituate at all over 21 days of repeated stress despite rising basal levels. Stress levels of corticosterone did not show significant change over days in either of the two restraint groups. Further, rising basal corticosterone levels suggest that repeated restraint produced a chronic stress state in these rats which may vary in some qualitative way with stressor intensity. Control rats placed in the same room as the stressed rats during the two stresses initially had increased corticosterone levels that matched the levels achieved in the stressed rats. The responses in control rats for the intense stress did not habituate completely in 7 days, whereas those in the control rats for the mild stress habituated completely within 3 days. These data suggest intraspecific communication of the intensity of stress.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
