Numbers of mitoses and of colchicine mitoses, and the duration of mitosis in corneal and tongue epithelium as well as in hepatocytes of intact and adrenalectomized rats have been studied in dynamics within 24 hours. In the control animals, the 24 hours rhythm of mitotic activity and the duration of mitosis were established. The length of mitosis falls during the high rate mitotic activity to increase when the number of dividing cells is reduced. Adrenalectomy results in decreasing the amplitude of mitotic activity fluctuations and in diminishing the amount cells entering mitosis during the 24 hours period. The rate of physiological regeneration in tissues of adrenalectomized animals is reduced. Different sensibilities of investigated tissues to adrenal cortex hormones deficiency have been revealed.
研究了完整大鼠和肾上腺切除大鼠的角膜、舌上皮以及肝细胞在24小时内有丝分裂和秋水仙素诱导有丝分裂的数量，以及有丝分裂的持续时间。在对照动物中，确定了有丝分裂活动的24小时节律和有丝分裂的持续时间。有丝分裂的持续时间在有丝分裂活动率高时缩短，而在分裂细胞数量减少时增加。肾上腺切除术导致有丝分裂活动波动幅度减小，以及24小时内进入有丝分裂的细胞数量减少。肾上腺切除动物组织中的生理再生速率降低。已揭示所研究组织对肾上腺皮质激素缺乏的不同敏感性。
