| Abstract: | Effects of NaF on microstructure and ultrastructure of the liver of grass carp (Ctenopharyngodon idellus) were estimated by optical and transmission electron microscopy. After exposing to sodium fluoride at the concentrations of 0, 40, 80, 120 mg/L for 30 days, liver tissue sections were prepared for the observation of optical and transmission electron microscopy.The results showed that different degrees of damages were found in liver tissues of grass carp after exposing to different concentrations of NaF for 30 days.The histopathological changes involved disorders and fractures of hepatocyes cord, and vacuolization of liver cells in test groups, which got severer with the increasement of NaF concentrations. Ultrastructural changes showed that mitochondria in liver cells of test groups mild short-term exposed to NaF could cause damages to the liver of grass carp, and the degrees of damage increased with the doses of NaF. |
