Objective: This study aimed to investigate the inhibitory effects of Brucea javanica oil oral emulsion (BJOOE) on primary liver cancer induced by diethylnitrosamine (DEN). Methods:Rats were randomly divided into the control group, model group, and BJOOE group. Rats were given free access to water. DEN was administered intragastrically to induce liver cancer in rats. Five weeks later, rats were intragastrically administered with BJOOE for five times per week. The rats were killed after 14 weeks. Abdominal aortic blood samples were collected. The contents of ALT, AST, ALP, γ-GT, and AFP of serum were detected by an automatic biochemical analyzer. The liver index, spleen index, thymus index, and changes in liver cancer nodules of the surface were observed in rats. Changes in the number of liver cancer nodules of the surface were detected by imaging. Results:Compared with the control group, the liver index, spleen index, and number of nodules of the model group significantly increased, whereas the thymus index significantly decreased (P<0.01). The levels of ALT, AFP, AST, ALP, andγ-GT of serum in the model group were significantly higher than those in the control group (P<0.01). Compared with the model group, BJOOE significantly reduced the liver index, spleen index, and number of cancer nodules, but increased the thymus index in the liver of rats with cancer (P<0.01). The levels of ALT, AFP, AST, ALP, andγ-GT of serum in rats with hepatic carcinoma significantly improved (P<0.01 or P<0.05). Conclusion:BJOOE could inhibit primary liver cancer, and the underlying mechanisms are complex.
