Abstract: An objective of the present disclosure is to provide an adsorption material that has a carrier material with retained physical strength, and efficiently adsorbs an immunosuppressive protein. The present disclosure provides an adsorption material for immunosuppressive protein. The adsorption material includes a water-insoluble carrier to which at least one nitrogen-containing compound selected from a polyamine represented by a predetermined formula and aliphatic amines represented by predetermined formulae is bound. A total content of amino groups on the water-insoluble carrier is more than 0 μmol and 2500 μmol or less per 1 g, and a content of primary amino groups on the water-insoluble carrier is 450 μmol or less per 1 g.

Abstract: It is an object to provide a surgical tool for excising a hard solid organ such as cirrhotic liver or cutting the organ into a groove without causing bleeding. The inventors of the present invention have found that an organ resection tool including a brush-like structure capable of performing microwave irradiation and/or a brush-like structure capable of receiving a microwave can achieve the above-mentioned object, to thereby arrive at the present invention (organ resection tool including a brush structure capable of performing microwave irradiation). For example, an organ can be crushed or scraped away by manually abrading the organ with a brush of a solid organ resection tool including a brush structure capable of performing microwave irradiation according to the present invention. Further, the organ can be concurrently coagulated through the microwave irradiation to stop bleeding.
