[Morphological peculiarities of rat liver reaction to chronic xenobiotic exposure].

The data of the morphological studies of liver of animals subjected to chronic (3 months long) intoxication with different chemical substances (ammonium nitrogen, nitrite nitrogen, fluorine, chromium, arsenic) are presented. The xenobiotics tested induced stereotyped responses in liver which differed in their intensity and the extent of hemomicrocirculatory and inflammatory-destructive alterations. Most pronounced reactive changes were found in animals exposed to arsenic compounds, while sodium nitrate caused practically no destructive changes in hepatocytes.
