Rat were exposed to 80% nitrous oxide in oxygen for 1 and 18 h. Met-enkephalin levels in the dorsal raphé, medial thalamus, periaqueductal grey, raphé magnus and locus coeruleus were measured by radioimmunoassay in control and treated animals. There was no change in Met-enkephalin levels at either time point in any of the brain areas examined.
将大鼠暴露于含80%氧化亚氮的氧气中1小时和18小时。通过放射免疫分析法测量对照动物和处理动物中中缝背核、丘脑内侧、导水管周围灰质、中缝大核和蓝斑中的甲硫氨酸脑啡肽水平。在所检查的任何脑区中,两个时间点的甲硫氨酸脑啡肽水平均无变化。
