A process for removing iodine using gold particles includes contacting a solution including iodine, with gold particles. The iodine is adsorbed onto the gold particles and then removed. A device for removing iodine using gold particles includes gold particles in a stationary phase and is configured to contact a solution including iodine, with gold particles, to thus adsorb the iodine onto the gold particles and remove the iodine.

The present invention relates to a pharmaceutical composition for the prevention and treatment of tissue injury caused by irradiation which comprises silkworm hemolymph as an active ingredient. Particularly, when the silkworm hemolymph of the present invention was administered to an animal model with liver damage induced by irradiation, plasma AST and liver MDA were significantly decreased, indicating that the silkworm hemolymph of the invention can be effectively used as a composition for the prevention and treatment of disease caused by the exposure on radiation including tissue injury caused by irradiation, etc.

A method for labelling a sulfide compound with technetium or rhenium, comprising the reaction of a disulfide compound with pertechnetate or perrhenate in the presence of borohydride exchange resin to obtain a complex of technetium or rhenium with the sulfide compound. The method can directly label disulfide compounds with technetium or rhenium, can skip the synthetic step of thiol-protected S-precursor, and is useful for high value-added radiopharmaceuticals.

The present invention relates to a method of preparing technetium or rhenium complex for radiopharmaceuticals, through reaction of pertechnetate or perrhenate with a ligand in the presence of a reducing agent, wherein the reducing agent is a borohydride exchange resin (BER). The borohydride exchange resin of the present invention has advantages of being stable in a wide range of Ph, including acidic or alkaline condition(Ph 2&#x2dc;14) and thus being applicable to biological materials as well as being easily removable through filtration when being administrated. Also since the radiolabelled complex is produced under conditions milder than those required for the conventional reducing agents as well as has high radiochemical purity and high labeling efficiency, the conventional reducing agents can be replaced by the BER of the present invention.
