    摘要: A novel polysaccharide derivative, a drug carrier comprising a novel polysaccharide derivative, and a drug complex are disclosed. The polysaccharide derivative according to the present invention comprises a polysaccharide having a carboxyl group in which a peptide chain is introduced at a part or all of the carboxyl groups of the polysaccharide. The peptide chain comprises 1-8 amino acids which may be the same or different. A part or all of the amino groups in the peptide chain which are not involved in the linkages with the carboxyl groups of the polysaccharide or the carboxyl groups in the peptide chain may form an acid amide linkage or an ester linkage with a carboxyl group, an amino group or a hydroxyl group of a third compound such as drugs. The polysaccharide derivative has a property of accumulating in a high amount at a tumor, and thus can deliver efficiently a drug which has a side-effect or a limited sustainment of the drug efficacy to the tumor.

    摘要: A method of preventing dust from adhering to a wall of a combustion apparatus, such as a furnace wall or exhaust duct, is carried out by forcing gas through a porous refractory member forming the wall. Specifically, the furnace wall or exhaust duct wall to which dust might otherwise adhere is made of a porous refractory member and gas is injected through the pores of the refractory member. In an incinerator, the refractory porous member extends around the periphery of a liquid injection nozzle, so that gas fed to the inside of the incinerator through the refractory porous member prevents flower from accumulating at the periphery of the end of the nozzle and attenuates the wake of the injected liquid so as to suppress the entrainment of dust in the liquid. In a melting furnace, the refractory porous members provide the ceiling of a slag separating chamber and the entrance of an exhaust gas duct open to the upper portion of the slag separating chamber. Plate-like members form wind chambers with the porous refractory members so that cooling gas fed into the wind chambers is forced into the slag separating chamber and exhaust duct through the pores in the refractory porous members.
