The circadian rhythms in both consumption of food by rats and in the mitotic rate in epithelial cells lining the bases of the crypts of Lieberkühn of the proximal jejunum were studied in normal and in chemically sympathectomised rats. In normal rats both food consumption and crypt cell mitotic rat showed a distinct circadian rhythm, both parameters having a peak around 00.00 to 04.00 hours. Following chemical sympathectomy the circadian rhythm in food consumption was essentially unchanged whereas that in the crypt cell mitotic rate was abolished.
在正常大鼠和化学性交感神经切除的大鼠中，研究了大鼠食物摄入量以及空肠近端利伯kühn隐窝底部上皮细胞有丝分裂率的昼夜节律。在正常大鼠中，食物摄入量和隐窝细胞有丝分裂率均呈现明显的昼夜节律，两个参数均在00:00至04:00左右达到峰值。化学性交感神经切除后，食物摄入量的昼夜节律基本未变，而隐窝细胞有丝分裂率的昼夜节律则消失了。
