Abstract: An inkjet-recording medium has excellent various preservabilities, for example, the lightfastness of an image, resistance to bleeding under high-temperature and high-humidity conditions, and resistance to indoor fading and discoloration when a surface of a printing paper is subjected to laminating treatment. In an inkjet-recording medium having an ink-receiving layer on one surface of a base, the base having abilities to absorb and retain an ink solvent, a low oxygen-permeable resin layer preferably having an oxygen permeability of 10 cc/(m2·D·atm) at a temperature of 20° C. and at a relative humidity of 90% is provided on another surface of the base.

Abstract: This invention relates to a method for producing an LH-RH derivative, characterized in that a peptide fragment shown by general formula (1): pGlu-His-Trp-OR1 (where R1 denotes a lower alkyl) and a peptide fragment shown by general formula (2): H-Ser-Tyr-X-Leu-Arg-Pro-Y (where X denotes an amino acid selected from the group consisting of D-amino acids such as D-Leu, D-Ser(But), D-Trp, and (2-napthyl)-D-Ala, and Gly, and Y denotes Gly-NH2, Azgly(Azaglycine)-NH2 or NHR2 (R2 is lower alkyl)) are allowed to react in the presence of chymotrypsin or a chymotrypsin-like enzymes, to produce the LH-RH derivative shown by general formula (3): pGlu-His-Trp-Ser-Tyr-X-Leu-Arg-Pro-Y (where X and Y are as defined above). Since the method does not accompany a side reaction such as racemization, it enables simple separation and purification of LH-RH derivatives. Moreover the method enables to provide high yields, as well as recovery and recycling of unreacted peptide fragments, therefore it is valuable in industrial use.

Abstract: The present invention relates to a peptide represented by the general formula (1): ##STR1## wherein A is Ala or Gly; B is Ile or Val; C is Asn or Ser; D is Thr or Ser; E is Leu or Tyr; each of F, I and J is Lys or Arg, and at least one of F, I and J is Arg; G is Met, Leu or Nle; K is Asn or Ala; L is Ser or Ala; M is Ile or Val; and N is --NH.sub.2 or Asn--NH.sub.2, excluding the combination where A is Ala, B is Val, C is Asn, D is Thr, E is Leu, K is Asn, L is Ser, M is Ile, and N is Asn--NH.sub.2, and pharmaceutically acceptable salts thereof, as well as to a bronchus-expanding agent or a blood-flow-improving agent comprising said peptide or a pharmaceutically acceptable salt thereof as an active ingredient.
