摘要:
The present invention relates to a novel adhesive composition for surgical use application comprising an α-cyanoacrylate and a polymer being biodegradable and bioabsorbable into the living body organism. It is preferred that the polymer is a co-polymer of DL-lactic acid and ε-caprolactone, or co-polymer of DL-lactic acid, ethylene glycol and ε-caprolactone, or a co-polymer of ethylene glycol and ε-caprolactone.
摘要:
The present invention provides a composition for efficiently protecting and preserving organs, tissues or cells. In particular, the present invention provides a protective composition which can be used during operations. Specifically, the present invention provides a composition for protecting and preserving organs, tissues or cells, comprising a polyphenol. A method is also provided for protecting an organ, tissue or cell in a subject, comprising 1) exposing the organ, tissue or cell to a polyphenol. Such a composition and a polyphenol is effective in protecting a function of an organ (particularly, the heart, brain, nerve, spinal cord and the like).

摘要:
This is to provide a medical-use adhesive having self-degradation property that enables sufficient adhesion even on wet living body portion, to which body fluid such as blood oozes out heavily, and even especially when the wet living body portion is arranged along a vertical plane. This is to provide also a medical-use adhesive excellent in obliteration of a pinhole. A first part of two-part adhesive is powder of aldehyde-groups-introduced alpha-glucan having a weight-average molecular weight in a range of 1000 to 200,000. A second part of two-part adhesive is aqueous solution or powder of amino-groups-containing polymer that is formed of a polymer chain of amino-group-containing units and has a molecular weight in a range of 1000 to 20,000. A mixture of the first and second liquids at a time of mixing them has pH in a range of 5.0 to 8.0.
摘要:
It is aimed to provide medical-use adhesive and medical-use hydrogel resin that satisfy general requirements for such adhesive and resin and are rapidly disintegrated at an elapse of designed time period, which may be rather freely controlled or adjusted. A first liquid for the adhesive or the resin is an aqueous solution of aldehyde-groups-introduced alpha-glucan having a weight-average molecular weight in a range of 1000 to 200,000. A second liquid for the adhesive or the resin is aqueous solution of amino-groups-containing polymer that is formed of a polymer chain of amino-group-containing units and has a molecular weight in a range of 1000 to 20,000. A mixture of the first and second liquids at a time of mixing them has pH in a range of 5.0 to 8.0.
摘要:
Bone-adherent implant with shock-absorbing property comprising: a substrate; a first film on the substrate, which is comprised of a polymer and has a functional group that enables adsorption of calcium ions; and a second film formed on the first film and being comprised of calcium phosphate. A manufacturing method of the implant comprising: forming said first film on a substrate; and subsequently, dipping the substrate in a calcium ion solution and in a phosphate ion solution alternately so as to form the second film.

Provided are a cold storage method and a cold storage liquid that are suitable for non-freezing refrigerated storage of human or animal stem cells such as iPS cells or embryos in a non-frozen state. According to an embodiment, the non-freezing refrigerated storage liquid is: a mixture liquid (HTMα, HTMx2c13), in which MEM-alpha (Minimum Essential Medium Eagle (MEM) Alpha Modification) is mixed with a UW solution (UW_sln; BELZER UW (registered trademark) COLD STORAGE SOLUTION), or a modified UW solution (polymer component being changed to PVA), are mixed in a ratio of about 1/1 to 1/2; or a storage liquid having a composition equivalent to the mixture liquid, especially in respect of concentrations of potassium ions and sodium ions. And, arousal period(s) of maintaining a temperature of 30°C to 37°C is inserted at each of two to five days, into a non-freezing refrigerated storage period, which is made at 2°C to 8°C for 2 to 10 days or 4 to 20 days.
