Iron negative foci and nodules in safrole-exposed mouse liver made siderotic by iron-dextran injection.
A procedure for the production of mouse hepatic siderosis is described which results in extensive iron deposition in all lobular zones. Mice exposed to safrole for 24 weeks displayed basophilic and acidophilic foci which did not accumulate iron. 36 weeks of dietary safrole exposure resulted in nodular lesions comprised of basophilic and hyalinized cells. The nodules displayed decreased or negative reactions for iron in hepatic parenchymal cells when the surrounding liver was siderotic.
