Abstract: The present invention relates to a composition for preventing or treating acquired immunodeficiency syndrome (AIDS), comprising one or more of the following: a homogenous cell line, and a lysate, an extract and a culture thereof as an active ingredient. The homogenous cell line, the lysate, the extract and the culture thereof, which are derived from a natural product, minimize adverse side effects of prior therapeutic agents and safe for the human body. Further, they effectively increase the count of T cells such as CD4+ T cells and decrease the number of HIVs, thereby preventing opportunistic infection, dysneuria, and neoplaia caused by immune incompetence, and ultimately the risk of death. Therefore, they are useful in preventing and treating AIDS, and relieving symptoms of AIDS.

Abstract: The present invention relates to a composition for preventing or treating cancer, which contains, as an active ingredient, a Taxus cambium- or procambium-derived cell line; a lysate thereof; an extract thereof; or a culture medium thereof. The cell line, the lysate, the extract, and the culture medium has minimized side effects compared to the conventional therapeutic drugs, is safe to the human body, is involved directly in the growth of cancer to induce cancer cell death, and shows anticancer activity of inhibiting angiogenesis occurring in carcinogenesis. Accordingly, the cell line, the lysate, the extract and the culture medium is useful for the prevention, treatment and alleviation of cancer.

Abstract: The present invention relates to a composition for preventing or treating liver diseases, which contains, as an active ingredient, any one or more of a homogeneous cell line derived from the cambium of Panax ginseng, including wild ginseng or ginseng, a lysate thereof, an extract thereof and a culture medium thereof. The homogeneous cell line according to the present invention, a lysate thereof, an extract thereof and a culture medium thereof have minimized side effects compared to existing agents for treating liver diseases, and thus are safe for the human body. Also, they can increase the levels of s-antibody (HBsAb) and e-antibody (HBeAb) against hepatitis virus and inhibit the proliferation of hepatitis virus, and thus they are useful for the prevention and treatment of liver diseases. In addition, they have the effect of lowering the levels of liver injury, and thus are useful as a functional food for improving liver function.
