| 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) |
| active transport | <biochemistry, chemistry> Transport of ions, nutrients or other molecules into a cell against a concentration gradient, this requires the expenditure of energy through ATP hydrolysis. (06 May 1997) |
| anterograde transport | Movement of material from the cell body of a neuron into axons and dendrites retrograde axoplasmic transport also occurs). (18 Nov 1997) |
| atrial transport function | The role of the atria in filling and stretching the ventricles by their presystolic contraction, without which the force of ventricular contraction and hence the cardiac output may significantly decrease. (05 Mar 2000) |
| axonal transport | Directed transport of organelles and molecules along a nerve cell axon. Transport can be anterograde (from the cell body) or retrograde (toward the cell body). (alberts et al., molecular biology of the cell, 3d ed, pg3) (12 Dec 1998) |
| axoplasmic transport | Transport by way of flow of axoplasm toward cell soma (retrograde) or toward axon terminal (anterograde). (05 Mar 2000) |
| biological transport | The movement of materials (including biochemical substances and drugs) across cell membranes and epithelial layers, usually by passive diffusion. (12 Dec 1998) |
| biological transport, active | The movement of materials across cell membranes and epithelial layers against an electrochemical gradient, requiring the expenditure of metabolic energy. (12 Dec 1998) |
