D-002 is a mixture of higher aliphatic primary alcohols purified from beeswax with antioxidant effects. Acute hepatotoxicity induced with CCl4 in rats has been related to increased hepatic lipid peroxidation and prevented with some antioxidants. This study investigated whether D-002 could prevent the acute CCl4-induced hepatotoxicity in rats. Animals were randomly distributed into four groups: a negative control treated orally with the vehicle and three groups injected with CCl4 (1 mL/kg) and treated orally either with the vehicle (positive control) or with D-002 (25 and 100 mg/kg). Eighteen hours after CCl4 dosing, rats were anesthetized, and livers were removed for histopathological studies. Some portions were taken and homogenized for assessing malondialdehyde (MDA) concentrations. Positive, but not negative, controls showed ballooned cells, swollen hepatocytes, and lipid-included hepatocytes, as well as necrotic areas and inflammatory infiltrates. D-002 (25 and 100 mg/kg) dose-dependently and significantly (P<.01) decreased the frequency of all abnormal liver cell types and increased that of normal hepatocytes compared with the positive controls, not showing necrotic areas or inflammatory infiltrates. D-002 dose-dependently decreased hepatic MDA levels, but only in the highest dose group were these levels significantly lower than in the positive control. In conclusion, D-002 effectively prevented the histological liver disturbances and lowered MDA levels, a marker of cellular lipid peroxidation, in rats treated with CCl4. Since increased liver lipid peroxidation has been postulated as a cause of CCl4-induced liver damage in rats, the preventive effects of D-002 could be due to its antioxidant action, but such a proposal still requires further research.
