The diurnal rhythm of plasma corticosterone (B) in adult male rats was investigated 6, 12, 18, 24, 30 and 36 weeks after frontal isolation of the medial basal hypothalamus (MBH) and was compared to that of sham-operated controls. Taking blood samples by heart puncture, it was possible to follow the same groups of animals during the entire experimental period. In accordance with earlier reports, frontal deafferentation of the MBH abolished the diurnal rhythm of plasma B 6 weeks after surgery. No change was observed in this respect until the 30th postoperative week. At that time, however, the rhythm tended to return and was present by the 36th week in the operated animals.
研究了成年雄性大鼠内侧基底下丘脑（MBH）额叶隔离后6、12、18、24、30和36周时血浆皮质酮（B）的昼夜节律，并与假手术对照组进行了比较。通过心脏穿刺采集血样，可以在整个实验期间跟踪同一组动物。与早期报告一致，MBH额叶去传入在手术后6周消除了血浆B的昼夜节律。在这方面直到术后第30周都没有观察到变化。然而，在那时，节律趋于恢复，并且在手术动物中到第36周时出现了这种节律。
