Abstract: An immunostimulatory oligonucleotide that is represented by the general formula 5?-Gm-GACGATCGTC-Gn-3? or 5?-Gm-CACGATCGTG-Gn-3? (in the formula, m and n are each independently an integer from 1 to 9 and m+n=10) and that comprises any of the following base sequences: GGACGATCGTCGGGGGGGGG (SEQ. ID. NO.: 1), GGGACGATCGTCGGGGGGGG (SEQ. ID. NO.: 2), GGGGACGATCGTCGGGGGGG (SEQ. ID. NO.: 3), GGGGGGGACGATCGTCGGGG (SEQ ID NO: 4), GGGGGGGGACGATCGTCGGG (SEQ. ID. NO.: 5), GGGGGGGGGACGATCGTCGG (SEQ. ID. NO.: 6), GGGGGGGGGGACGATCGTCG (SEQ. ID. NO.: 7), and GGGGGGGGGCACGATCGTGG (SEQ. ID. NO.: 8).

Abstract: The invention provides a method for increasing the color density of a dyed fabric material of, especially, a synthetic fiber as well as the fastness of the color to rubbing and washing. The inventive method comprising (a) pretreating the dyed fabric material with an organopolysiloxane which is an amino-modified organopolysiloxane or a dimethylpolysiloxane, and then (b) exposing the thus pretreated dyed fabric material to low temperature plasma of an inorganic gas under a reduced pressure. The inorganic gas is preferably oxygen or a gaseous mixture containing at least 10% by volume of oxygen. The color-deepening effect is particularly remarkable when the color of the dyed fabric material is black to impart increased graveness and vividness of the color.

Abstract: Hydrophilicity of a poorly hydrophilic fabric material of synthetic fibers can be remarkably and durably increased by the synergistic effect of the treatments first with a specific hydrophilic agent, e.g. water-absorbent agent and antistatic agent, and then by exposure to low temperature plasma generated in an atmosphere of oxygen or oxygen-containing gaseous mixture so that the capacity of the fabric material for water absorption is greatly increased and the antistatic performance thereof is greatly improved with decreased surface resistivity and charge voltage induced by rubbing.
