|---|---|
| reversed passive anaphylaxis | An anaphylactic reaction induced in an animal injected with a specific antigen, which will bind to reactive tissue, and then, after a latent period, with serum from another animal previously sensitised to the identical antigen. Synonym: reversed anaphylaxis. (05 Mar 2000) |
| reverse passive haemagglutination | If antibodies are bonded to the surface of red blood cells haemagglutination will occur if the appropriate bi or multivalent antigen is added in soluble or microparticulate form. Used as a test for for example Hepatitis B virus in the serum. (18 Nov 1997) |
| motion therapy, continuous passive | Movement of a body part initiated and maintained by a mechanical or electrical device to restore normal range of motion to joints, muscles, or tendons after surgery, prosthesis implantation, contracture flexion, or long immobilization. (12 Dec 1998) |
| continuous passive motion | A technique in which a joint, usually the knee, is moved constantly in a mechanical splint to prevent stiffness and to increase the range of motion. (05 Mar 2000) |
| specific passive immunity | See: acquired immunity. (05 Mar 2000) |
| natural passive immunity | Immunity conferred by the mother on the foetus or newborn. (14 Nov 1997) |
| immunization, passive | Transfer of immunity from immunised to non-immune host by administration of serum antibodies, or transplantation of lymphocytes (adoptive transfer). (12 Dec 1998) |
| euthanasia, passive | The withdrawing or withholding of extraordinary means used to prolong life. (12 Dec 1998) |
| aid to families with dependent children | Financial assistance provided by the government to indigent families with dependent children who meet certain requirements as defined by the social security act, title IV, in the u.s. (12 Dec 1998) |
| androgen-dependent secretory protease | <enzyme> Glycoprotein from dog prostate; hydrolyzes arginine and lysine-containing amide and ester protease substrates Registry number: EC 3.4.99.- Synonym: ads-protease (26 Jun 1999) |
| antibody-dependent cell cytotoxicity | The phenomenon of antibody-mediated target cell destruction by non-sensitised effector cells. The identity of the target cell varies, but it must possess surface IgG whose fc portion is intact. The effector cell is a "killer" cell possessing fc receptors. It may be a lymphocyte lacking conventional b- or T-cell markers, or a monocyte, macrophage, or polynuclear leukocyte, depending on the identity of the target cell. The reaction is complement-independent. (12 Dec 1998) |
| antibody-dependent enhancement | Enhancement of viral infectivity caused by non-neutralizing antibodies. There are at least two mechanisms known to account for this: mediation by fc receptors (receptors, fc) or by complement receptors (receptors, complement). Either the virus is complexed with antiviral IgG and binds to fc receptors, or virus is coated with antiviral IgM and binds to complement receptors. (12 Dec 1998) |
| aromatic NADH-dependent nitroreductase | <enzyme> See also record for 1-nitroreductase; type I nitroreductase is not inhibited by oxygen Registry number: EC 1.- Synonym: nitrofuran reductase, nitrofurazone reductase, type I nitroreductases, NADH-dependent nitro reductase, nitrofurantoin reductase, p-dinitrobenzene reductase, benznidazole nitroreductase, nifurtimox nitroreductase, oxygen-insensitive NADPH nitroreductase, nitrobenzene nitroreductase (26 Jun 1999) |
| aspartic acid 2-oxoglutarate-dependent dioxygenase | <enzyme> Hydroxylates one aspartic acid residue in the first egf-like unit of factor ix Registry number: EC 1.14.11.- Synonym: aspartate 2-oxoglutarate dioxygenase, asp-2-og-dioxygenase, aspartyl beta-hydroxylase, aspartyl (asparaginyl) beta-hydroxylase (26 Jun 1999) |
