Abstract:
PROBLEM TO BE SOLVED: To provide materials involved in the control of the circulatory system, more specifically, to provide a recombinant material useful for the production of a thrombin receptor, to provide use of the receptor as a diagnostic tool, and to provide a therapeutic agent which either stimulates or blocks thrombin receptor activation and diagnostic compositions relevant to the receptor. SOLUTION: The materials include a mutant thrombin, a DNA molecule, and a recombinant host cell; wherein the mutant thrombin, producible in a recombinant way, is such that the 57- and/or 99- and/or 205-position(s) is (are) different from that(those) in a wild-type thrombin b-chain, the DNA molecule has an expression system capable of producing the thrombin in a host when transformed to the recombinant host and includes a DNA sequence encoding the thrombin linked agonistically to an abnormal regulatory sequence so that the expression system is operable in the host, and the recombinant host cell is subject to transformation by the expression system.

Abstract:
PROBLEM TO BE SOLVED: To provide another method that increases the specificity of blocking the formation of active prothrombinase complex and can prolong the duration time of this action. SOLUTION: The objective medicine is the factor Xa of the blood factor that is modified so that the half-life may be transitorily prolonged in the serum and the modified blood factor gives the activated form of the blood factor in the presence of serum. The factor Xa that is the blood factor modified so that the half-life thereof may be prolonged in the serum is mixed with a pharmaceutically acceptable excipient and is used for treating hemophilia wherein the activated form of the blood factor is produced in the presence of serum.
Abstract:
PROBLEM TO BE SOLVED: To provide another method of antithrombosis treatment by specifically inhibiting the bonding of vWF to a GPIb-IX complex containing platelets. SOLUTION: A DNA molecule composition comprising DNA molecules each containing a sequence encoding a platelet anti-adhesive peptide obtained from snake venoms selected from the following group; Agkistrodon, Bitis, Bothrops, Cerastes, Crotalus, C, Echis carinatus sochurecki, Eristicophis macmahoni, Pseudocerastes persicus, Sistrurus, Trimeresurus, and Vipera.
Abstract:
PROBLEM TO BE SOLVED: To obtain an antibody capable of inhibiting the PDGF(platelet derived growth factor) BB lag phase of cells expressing human β-PDGF in a defined concentration to a higher extent than a specific value and useful e.g. for the therapy and diagnosis of adult dyspnea syndrome-related pulmonary fibrosis or the like. SOLUTION: This antibody can specifically bind to a β-PDGF receptor not existing in the fifth extracellular Ig-like domain and inhibits the PDGF BB lag phase of cells expressing β-PDGF in an antibody concentration of 10 μg/mL to an extent of >80%. The antibody preferably inhibits the binding of the PDGF BB to cells expressing a β-PDGF receptor or binds to the extracellular Ig-like domain of a β-PDGF receptor. A composition comprising the antibody and a medicinally permissible excipient preferably is prepared. The daily dosage level of the antibody preferably is from 0.1 mg/kg to 10.0 mg/kg.
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject composition useful for the treatments of restenosis, adult respiratory distress syndrome-related fibroid lung and the like by including an antibody specifically bindable to a specific growth factor receptor so as to be capable of specifically inhibiting the receptor's activation. SOLUTION: This composition is obtained by including an anti-platelet-derived growth factor(PDGF) receptor antibody at effective levels. This antibody is preferably a monoclonal antibody, preferably anti-PDGF-β-receptor antibody. The above composition is preferably a medicinal composition to inhibit the proliferation of smooth muscle cells at the lesion sites of blood vessel and- preferably comprises enough quantity of the anti-growth factor receptor antibody to inhibit mitosis induction and/or transfer of smooth muscle cells of blood vessel at the lesion sites, and also preferably the above antibody is selected from anti-PDGF-βreceptor antibodies. In the above composition, an aqueous carrier, conventional nontoxic solid carrier or the like can be used.
