机体机能多以24小时周期而变动。例如睡眠—觉醒,血中激素量的节律等。这种日周期节律不仅反映在功能方面,也反映在细胞形态方面。肝细胞日节律的记载起始于糖原代谢。F-orsgren 在用光学显微镜观察兔肝细胞时,发现在24小时内糖原含量有很大变化。在他研究的基础上,又有许多学者从形态学方面,如肝细胞的糖原含量变化,组织化学方面以及生物化学方面进行了研究。肝组织的节律,不仅表现在有关糖代谢物质,就是在 DNA 含量、白蛋白含量方面也呈现明显的日周期变动,可以想像肝细胞的许多
Body functions and more changes in a 24-hour cycle. Such as sleep-wake, hormonal blood rhythm and so on. This daily cycle rhythm is not only reflected in the functional aspects, but also reflected in the cell morphology. Liver rhythm of the rhythm of the record starts from glycogen metabolism. F-orsgren In the observation of rabbit liver cells by light microscopy, there was a large change in glycogen content within 24 hours. On the basis of his research, there are many scholars from the morphological aspects, such as changes in the glycogen content of hepatocytes, histochemistry and biochemistry were studied. Rhythms of liver tissue, not only in the performance of glucose metabolites, also show significant changes in the daily cycle in terms of DNA content and albumin content, many of which are imaginable
