The aim of this study was to investigate the effectiveness of hydatid cyst toxin fractions in mice. Fifty male mice were divided into five groups with 10 mice for each group the first group as control the second group was injected with toxin fractions at the concentrations 25Mg/ml PBS, the third group are the mice that injected intraperitoneally with toxin fractions at the concentrations 25Mg/ml PBS and treated with vitamin E at the concentration of 40 mg/ 100 g of feed, the fourth group was injected intraperitoneally with 1 ml of raw fluid and the fifth group was injected intraperitoneally of 1ml of row fluid with the vitamin E at the concentration of 40 mg /100gm feed. The mice were sacrificed after 15 and 30days post injection, specimen of heart are fixed in 10% neutral buffered formalin for histological techniques. The histopathological changes in cardiomyocyte were edema, infiltration of mononuclear cell and thickening of blood vessels wall with congestion in it. The results confirm that the toxin fraction have more effect than the raw fluid and that there is the regeneration effect of vitamin E on hydatid cyst cardiomyocyte.
