A technique for obtaining repeated liver biopsies from rats.
Many morphological, pharmacological and toxicological studies of hepatotoxicity require frequent sampling of liver over time. In the past this has been achieved by including large numbers of animals in the study and killing subgroups at different times. In this paper we describe a technique for repeated liver biopsy that procures sufficient liver tissue for histopathological assessment and for additional studies, for example measurement of hepatic iron concentration or vitamin A measurement. The advantages and disadvantages of this technique are discussed.
