Abstract

The prolactin (PRL) and corticosterone (CORT) responses to footshock stress were measured in rats after the first, fifth, and 57th exposure to the stress procedure. No reduction in the PRL or CORT responses was seen after repeated application of the footshock stress and the animals showed similar behavioral responses throughout. These results indicate that the hormonal and behavioral responses to footshock stress are not attenuated after an animal has been repeatedly exposed to the stress.

摘要

在大鼠首次、第五次和第57次接受足部电击应激程序后，测量其对足部电击应激的催乳素（PRL）和皮质酮（CORT）反应。在反复施加足部电击应激后，未观察到PRL或CORT反应降低，并且动物在整个过程中表现出相似的行为反应。这些结果表明，在动物反复暴露于应激后，其对足部电击应激的激素和行为反应并未减弱。
