[Toxic effect of carbon tetrachloride on the myocardium. II. Experimental part. B. Ultrastructure of the myocardium of rats in acute carbon tetrachloride poisoning].

Rat's myocardium was examined. The tissue material was collected 3, 6 and 12 hours after carbon tetrachloride administration. The poison was administered by gastric tube in single dose of 0.6 ml/100 g of body weight. Electron microscopic examination revealed a reaction of endoplasmic reticulum damage to mitochondrium and myofibrils.
