Rats placed as intruders in a long-established colony showed significant elevations of plasma corticosterone after 10-20 minutes of intruding. This rise was prevented by 5 days pretreatment with chlordiazepoxide (5 mg/kg). The rats resident in the colony had significantly higher basal corticosterone concentrations compared with singly housed rats but the same as rats housed in groups of six in a normal cage. The resident rats showed no elevation of plasma corticosterone in response to 20 minutes of an intruder in the colony.
作为入侵者被放入一个长期存在的鼠群中的大鼠，在侵入10 - 20分钟后，血浆皮质酮显著升高。这种升高可通过氯氮卓（5毫克/千克）预处理5天来预防。与单独饲养的大鼠相比，鼠群中的常驻大鼠基础皮质酮浓度显著更高，但与正常笼子中6只一组饲养的大鼠相同。常驻大鼠在面对鼠群中有入侵者20分钟时，血浆皮质酮没有升高。
