足电击产生了超过2倍的增加释放去甲肾上腺素(NA)从额叶皮层的自由移动的大鼠。通过给予地西泮(5 mg/kg i. p.)几乎完全防止了急性应激的影响。单独地西泮抑制皮质NA释放,在注射后90分钟观察到最大抑制(~ 57%)。因此,皮质NA的释放似乎是一个可靠的指标,中央去甲肾上腺素能活动的压力条件。
Foot-shock produced a more than 2-fold increase in noradrenaline (NA) release from the frontal cortex of freely moving rats. The effect of acute stress was almost completely prevented by the administration of diazepam (5 mg/kg i.p.). Diazepam alone inhibited cortical NA release, the maximal inhibition (-57%) being observed 90 min after the injection. Cortical NA release therefore appears to be a reliable index of central noradrenergic activity in response to stressful conditions.
