Abstract
Antitumor activity of Korean mistletoe extract (KM-110) and European commercial mistletoe preparation (Helixor) was investigated. KM-110 showed the cytotoxic effect that it is high for various tumor cell lines and normal splenocytes in comparison with Helixor. Administration of two mistletoe extracts (100 μg) to mice did not show any significant changes on the level of glutamic-oxaloacetic transaminase (GOT), glutamic-pyruvate transaminase (GTP), blood creatinine (CRE) and blood urea nitrogen (BUN) in sera. The culture supernatant of macrophages stimulated with KM-110 inhibited effectively tumor growth whereas Helixor had little effect. Administration of KM-110 or Helixor resulted in a effective inhibition of lung metast asis after the i.v. inoculation of colon 26-M3.1 lung carcinoma, B16-BL6 melanoma and L5178Y-ML25 lymphomas. In all cases, the mice treated with KM-110 showed more effective anti-tumor metastatic activity than the mice of Helixor. These results suggest that Korean mistletoe extracts, KM-110 might be used as an alternative methods having antitumor activity like European mistletoe preparation, Helixor.
