The conditioned avoidance response and the cerebral levels of dopamine and noradrenaline have been studied in control rats and in rats submitted to a hypobaric hypoxia. A protection against the effects of hypoxia was induced by both dihydroergocornine (20 microgram/kg) and dihydroergocryptine (100 microgram/kg), and the noradrenaline level did not decrease. This stabilization of cerebral noradrenaline level seems to be the main protection factor observed.
在对照大鼠和接受低压低氧处理的大鼠中，研究了条件性回避反应以及大脑中多巴胺和去甲肾上腺素的水平。双氢麦角碱（20微克/千克）和双氢麦角隐亭（100微克/千克）均可诱导对低氧影响的保护作用，且去甲肾上腺素水平并未降低。大脑去甲肾上腺素水平的这种稳定似乎是观察到的主要保护因素。
