Objective: To observe the inhibitory effects of biotic royal jelly on the ascitic hepatoma cell H22. Methods: Mice bearing H22 tumor were fed on different types of royal jelly: No.1, 2 and 3. Their anti-tumor effects were observed in vivo. The general royal jelly and normal saline were observed as control. Results: Among these biotic royal jelly, the biotic royal jelly No.1 showed obvious tumor-inhibiting and survival-prolonging effects. In addition, it increased the number of WBC and augmented the amount of IL-2 and IFN-γ; the pathological study also indicated the denaturing and necrosis of most tumor cells with nuclei constraining and cell membrane rupturing, and large amount of lymphocytes and plasmacytes infiltrating around the mass. Conclusion: The No.1 biotic royal jelly has obvious anti-tumor effect, and it may take effects by inhibiting or killing tumor cells and improving the immunity of the host.
