title: Histochemical observations on nodules induced in the mouse liver by phenobarbitone.
abstract: This study describes the histochemical reactions seen in nodules of the mouse liver. The nodules were obtained from 13 animals treated for over 80 weeks with phenobarbiotone and three untreated mice. The morphology of the lesion depends upon the preparative techniques and only two lesions with persistent abnormal trabecular pattern metastasised. A varying pattern of histochemical reaction was seen. The aniline hydroxylase reaction was dense in simple nodules and in centrilobular areas of phenobarbitone-treated mice but was weak in the abnormal trabecular lesions. These results suggest that it is possible to predict behavioural characteristics of mouse hepatic nodules on the basis of certain morphological characteristics.
