Regular circadian variations in the mitotic index and in the number of cells synthesizing DNA (labelled nuclei index) were shown in the liver, epidermis, and in the exocrine portion of the pancreas in 7-day-old rats. The nature of these changes differed in the tissues under study. No regular correlations between the carcadian variations in these two indices were revealed.
在7日龄大鼠的肝脏、表皮和胰腺外分泌部,有丝分裂指数和合成DNA的细胞数量(标记核指数)呈现出规律的昼夜变化。在所研究的组织中,这些变化的性质有所不同。这两个指数的昼夜变化之间未发现规律的相关性。
