Bone marrow toxicity is a side effect of chemotherapy with anticancer drugs or the exposure to chemicals, such as benzene. When myelotoxicity occurs, the number of white blood cells decreases, which reduces immune functioning and increases the risk of infection or the development of tumors. Angelica gigas Nakai extract (AGNEX) and green coffee bean extract (GCBE) have many effects, such as anti-cancer and antioxidant effects, as well as effects on the immune functioning. In this experiment, the preventive effect of AGNEX and GCBE against benzene-induced bone marrow toxicity was confirmed in Sprague Dawley rats (SD rats) in vivo. Benzene (1 ml/kg mixed with corn oil 1:1) was intraperitoneally administered to SD rats (six weeks, N = 9/group) once a day, and AGNEX (12 mg/kg) and GCBE (6, 12, and 24 mg/kg) were administered orally daily for five weeks. To determine the preventive effect, AGNEX (12 mg/kg) and GCBE (6, 12, and 24 mg/kg) were administered orally before the administration of benzene. Consequently, AGNEX 12 mg/kg and GCBE 12 mg/kg were effective at reducing leukocytes and lymphocytes, specifically granulocyte. Additionally, the treatment also showed protective effects specifically on spleen and liver weight changes and spleen damage. Through this protective effect, AGNEX and GCBE were confirmed to prevent bone marrow toxicity by enhancing the functioning of the immune system.
