title: [Enzymatic phenotype of preneoplastic islands induced in the rat liver by diethylnitrosamine].
abstract: Diethylnitrosamine was injected to Sprague-Dawley rats after a partial hepatectomy, and enzyme histochemistry analysis was made after 35 weeks in the preneoplastic liver. The areas and volumes of the induced enzyme-deficient islands were calculated for glucose-6-triphosphatase, adenosine triphosphatase, and 5'-nucleotidase. The preneoplastic enzyme-deficient zones showed also an increased incorporation of tritiated thymidine.
