Quantitative changes in nucleoli of the mesothelial cells of the rabbit parietal peritoneum have been studied under regeneration when trauma is performed at 8--10 or at 20--22 o'clock. The animals are killed every 3 h after the operation, for 5 days. The nucleoli are studied continuously along 12.8 mm from the edge of the defect in film preparations. Under conditions of posttraumatic regeneration in the mesothelium the number of cells containing 2--3 nucleoli increases. It is connected with the process of synthesis activation which has a wave-like character in time and space. Dynamics of changes in the number of the nucleoli depends on the time when the operation is performed. The operation performed in the morning provokes more intensive and rhythmical reaction. It corresponds to the dynamics of mitotic activity which is also subjected to greater effects of the circadian mechanisms after morning performance of the operation.
研究了家兔壁腹膜间皮细胞核仁在再生过程中的定量变化，创伤分别在8 - 10时或20 - 22时进行。术后每3小时处死动物，持续5天。在薄膜制剂中，从缺损边缘沿12.8毫米连续研究核仁。在间皮创伤后再生的条件下，含有2 - 3个核仁的细胞数量增加。这与合成激活过程有关，该过程在时间和空间上具有波浪状特征。核仁数量变化的动态取决于手术时间。早晨进行手术会引发更强烈且有节律的反应。这与有丝分裂活动的动态变化相对应，在早晨进行手术后，有丝分裂活动也受到昼夜节律机制更大的影响。
