[Mechanism of functional adaptation of intestinal epithelial cells].
Using preparations of exogenous DNA and products of its in complete degradation, the causes leading to the compensatory changes of the share of membrane hydrolysus in the total invertase activity of the irradiated rat's intestinal epithelial were analysed experimentally. It is shown that the factor stimulating the enzyme redistribution towards the brush border zone is not the amount of mature villous cells, but the level of mitotic activity in crypts.
