This study aims to outline the histological progression of the Spirocerca lupi nodule from infection to neoplastic transformation. Sixty-two spirocercosis-induced nodules, 42 non-neoplastic and 20 neoplastic, were stained with HE. Ten non-overlapping high power fields per nodule were examined and non-neoplastic and neoplastic nodules were compared. Inflammation was scored 0-3 and revealed a sco...

Morphological analysis of transplantable pancreatic acinar carcinoma of rat has revealed a continuum of cells from those which totally lack mature secretory granules to cells with abun dant well-formed secretory granules. This tumor is easily dis sociable into single cells which incorporate [3H]thymidine and [3H]leucine into DNA and protein at a linear rate for 3 to 4 hr. The number of cells sy...
