Abstract: PURPOSE: Provided is a composition for promoting anti-cancer activity by using a Viscum album Coloratum. extract or its lectin components which inhibits the proliferation and metastasis of cancer. CONSTITUTION: A composition for promoting anti-cancer activity is characterized by containing, as an active ingredient, 1ng/mL of an arsenic compound or 5-10ng/mL of an alkylating anticancer agent obtained by detoxifying 5-10 microgram/mL of a hot water extract of Viscum album Coloratum. It is also characterized by containing, as an active ingredient, 1ng/mL of an arsenic compound or 5-10ng/mL of an alkylating anticancer agent obtained by detoxifying 10-20 ng/mL of a lectin containing component from the extract of Viscum album Coloratum.

Abstract: PURPOSE: A functional planting roller is provided to plant functional fabrics on the outer surface of a core through an electrostatic planting method to easily obtain a functional planting roller at a low price. CONSTITUTION: A functional planting roller(20) includes a roll-shaped core(21), and a plurality of functional fibers(24). The functional fibers are cut in a predetermined length and attached to the outer surface of the core in a predetermined density. The functional fibers are attached to the outer surface of the core through an electrostatic planting method. The core is made of one of a metal, insulating resin, conductive resin and paper. The length of the functional fiber is in the range of 0.5mm to 3mm. The functional fiber has conductivity.
