The intestinal epithelium of the small and large intestine of fetal rats (19th, 20th and 21st day of pregnancy) newborn and juvenile rats (1st to 50th day of life) adult rats (3rd to 4th month) and senile rats (18th to 30th month) was investigated by means of morphology, enzyme histochemistry and discelectrophoresis. The results obtained permit division of the development and aging of the rat intestinal epithelium into five periods: 1. The period of prenatal development. 2. The period of postnatal development. 3. The period of adaptation. 4. The stage of adult maturity. 5. The senile atrophy of the intestinal mucosa.
采用形态学、酶组织化学和圆盘电泳法对胎鼠(妊娠第19、20和21天)、新生鼠和幼鼠(出生后第1至50天)、成年鼠(第3至4个月)以及老年鼠(第18至30个月)的小肠和大肠肠上皮进行了研究。所获结果可将大鼠肠上皮的发育和衰老分为五个时期:1. 产前发育时期。2. 产后发育时期。3. 适应期。4. 成年成熟期阶段。5. 肠黏膜的老年萎缩期。
