Abstract

A 57-week-old male Wistar rat died one week before the end of a toxicity study. Necropsy revealed subcutaneous edema, hydrothorax, dilatation of all cardiac chambers, and congestion in several organs. Light and electron microscopic examinations revealed myocardial hypertrophy, degeneration, fibrosis, and disruption of myofibrils and variable sized mitochondria. The entity is concluded to be dilated cardiomyopathy.
