Provided are a composition for improving the brain function, which can be orally taken at a low dose, and a method therefor. The composition for improving the brain function contains, as the active ingredient, X-Pro-Pro-Leu-Thr-Gln-Thr-Pro-Val-Val-Val-Pro-Pro-Phe-Leu-Gln-Pro-Glu-Y (wherein X is nil or represents Ile or Asn-Ile; and Y is nil or represents Val-Met), X-Val-Val-Val-Pro-Pro-Phe-Leu-Gln-Pro-Glu-Y (wherein X is abscent or represents Thr-Gln-Thr-Pro, Pro-Leu-Thr-Gln-Thr-Pro, Leu-Thr-Gln-Thr-Pro or Pro; and Y is abscent or represents Val-Met), or a salt of the same. The method for improving the brain function comprises administering said peptide or a salt of the same.

A ligation tool for endoscope includes an overtube having an insertion lumen 21a made of a flexible material, which permits an insertion portion 11 of the endoscope to be inserted therethrough so as to advance and retreat, an O-ring 22 for ligation attached to a distal end of the overtube, and a operation wire 24 which is locked to the O-ring for ligation, has a distal portion extending to the proximal side of the overtube, and is operated to be pulled or pushed at its proximal side, thereby separating the O-ring for ligation from the tip of the overtube. According to this ligation tool for endoscope, time and effort taken to set the ligation tool for endoscope in the endoscope becomes unnecessary, a sufficient field of vision of the endoscope can be secured, and the curving performance of the tip of the insertion portion of the endoscope does not deteriorate. Furthermore, this ligation tool is also advantageous when endoscopic sclerotherapy is performed together.

An endoscopic incision system includes: an endoscope; a cylindrical member for covering at least a distal end of an insertion section of the endoscope; and at least an incision section for incising a living tissue, the incision section being provided to a distal end of the cylindrical member and being capable of being exposed from the distal end of the cylindrical member outwardly. In this configuration, the radially expanding incision section will not be twisted or bent, and the incision section prevented from inadvertent fall-off can maintain the desirable shape when it is operated and rotated.
摘要:
A method of performing diagnosis or treatment perendoscopically in which a guide catheter is inserted inside a body, and the guide catheter is made to protrude beyond a distal end portion of the endoscope; and in which a first diagnosis or treatment is performed by inserting a medical treatment device that performs the diagnosis or treatment of the body inside the guide catheter, and causing this medical treatment device to protrude by a first predetermined distance from the guide catheter; and in which the medical treatment device is extracted from the guide catheter; and in which a second diagnosis or treatment is performed by inserting a medical treatment device into the guide catheter, and causing the medical treatment device to protrude by a second distance which is adjusted in accordance with the first predetermined distance.
摘要:
A high-quality oxygen-absorbing resin composition which is obtained without suffering resin scorching. Also provided are pellets for the oxygen-absorbing resin composition which comprise a thermoplastic resin (A) and an oxidation catalyst. After the pellets are mixed with a trigger resin and a thermoplastic resin (C), the trigger resin functions as a trigger to cause the oxidation of the thermoplastic resins (A) and (C) to proceed. As a result, the resultant composition absorbs oxygen.

The present invention relates to resin pellets which comprises a thermoplastic resin (A) and an oxidation catalyst (B) which is not supported by any carrier, wherein if the peak area in the vicinity of 1715 cm−1 is defined to be Ic and the peak area observed in the vicinity of 1470 cm−1 is defined to be Im in the IR spectroscopic measurement of the pellets, the ratio: Ic/Im observed for the surface of the pellet is greater than that observed for the interior thereof. The pellets are thermoplastic resin pellets excellent in the oxygen-absorbing capacity and accordingly, they can suitably used as pellets for molding an oxygen absorptive resin article.
摘要:
An endoscope treatment system includes: an endoscope; and a treatment tool that has a sheath that is inserted in a channel of an insertion portion of the endoscope, in which projection portions that project outward from the sheath in the radial direction are provided, and engagement portions that engage the projection portions are provided near the channel of the endoscope.
摘要:
A stent delivery system 1 for supplying a stent to a body cavity which includes an endoscope 6 that has an insertion portion 5 with a curvature portion 3 disposed at the distal end thereof, a sheath 7 that is disposed with the insertion portion 5 inserted in the inside thereof and a stent 2 placed on the outer surface of the distal end side thereof; and a regulating portion 8 that regulates the relative movement of the stent 2 to the proximal end side of the sheath 7, with the sheath 7 formed of a length that allows the distal end of the insertion portion 5 that is inserted in the sheath 7 to protrude from the distal end of the sheath 7. In accordance with the present invention, it is possible to provide a stent delivery system that can place a stent by endoscope observation without the need of excessive diametrical contraction or additional expansion of the stent.
