[The influence of finely-ground vivarium feed on structural and functional condition of the liver hepatocytes in rats].

It was determined that a long-lasting consumption of a finely-growing feed vivarium even in the early postnatal period (60 days) causes certain changes in liver hepatocytes in rats. There takes place nucleous area and cell cytoplasm diminishing, accompanied by a decrease of albumines' synthesis level. In the later postnatal period (120 days) the hepatocytes' nucleus and cytoplasm area drastically increases, which is accompanied by the increase of albumine content in blood up to reference values. During the following period of the natal development (120-180 days) the levels as on the 128th day of the animals' development. In such a case the nucleous area slightly diminishes.
