摘要
Maudsley reactive (MR) and Maudsley nonreactive (MNRA) rats were submitted to a single session of acute 5-min immobilization stress and immediately sacrificed by decapitation. Subsequent neurochemical analysis revealed an elevation of 3,4-dihydroxyphenylacetic acid levels in the locus coeruleus and in the ventrolateral medulla, but not in the dorsomedial medulla, of rats of the two strains compared with nonstressed controls; This response was greater in the MR than in the MNRA group, suggesting a strain difference in the reactivity of the central noradrenergic cells to acute stress.
