| urticaria papulosa | A sensitivity reaction to insect bites, especially human and pet fleas, seen mostly in young children as wheals followed by papules on exposed areas. Synonym: lichen urticatus, prurigo infantilis, urticaria papulosa. (05 Mar 2000) |
|---|---|
| urticaria perstans | A form of chronic urticaria in which the wheals persist unchanged for long periods; includes urticarial vasculitis. (05 Mar 2000) |
| urticaria pigmentosa | The most common form of mastocytosis. It occurs primarily in children and is typically characterised by multiple persistent small, reddish-brown, hyperpigmented, pruritic macules and papules. They are located most commonly on the trunk, but seen also on the extremities, head, and neck. (12 Dec 1998) |
| urticaria subcutanea | Urticaria in which itching is present without the wheals. (05 Mar 2000) |
| urticaria tuberosa | A vascular reaction involving the deep dermis or subcutaneous or submucal tissues, representing localised oedema caused by dilatation and increased permeability of the capillaries and characterised by development of giant wheals. (18 Nov 1997) |
| urticaria vesiculosa | An eruption of wheals capped with subepidermal vesicles. Synonym: urticaria vesiculosa. (05 Mar 2000) |
| rabies immune globulin | Globulin fraction of pooled plasma of high anti-rabies virus titre from immunised persons. Synonym: rabies immunoglobulin. (05 Mar 2000) |
| measles immune globulin | A sterile solution of globulin's derived from the blood plasma of normal adult human donors; it is prepared from immune serum globulin that complies with the measles antibody reference standard; a passive immunizing agent. Synonym: measles immunoglobulin. (05 Mar 2000) |
| cellular immune theory | A concept, put forth by Elie Metchnikoff, that cells, not antibodies, were responsible for the immune response of an organism. (05 Mar 2000) |
| rho(d) immune globulin | Immunizing agent containing IgG anti-rho(d) used for preventing rh immunization in rh-negative individuals exposed to rh-positive red blood cells. (12 Dec 1998) |
| chickenpox immune globulin | Globulin fraction of serum from persons recently recovered from herpes zoster infection; used to prevent infection of high-risk children. Synonym: chickenpox immunoglobulin. (05 Mar 2000) |
| pertussis immune globulin | A sterile solution of globulin's derived from the plasma of adult human donors who have been immunised with pertussis vaccine; used both prophylactically and therapeutically. Synonym: pertussis immunoglobulin. (05 Mar 2000) |
| poliomyelitis immune globulin | A sterile solution of globulin's that contains those antibodies normally present in adult human blood; it is a passive immunologic agent that attenuates or prevents poliomyelitis, measles, and infectious hepatitis, and confers temporary but significant protection against paralytic polio. Synonym: poliomyelitis immunoglobulin. (05 Mar 2000) |
| primary immune response | <immunology> The immune response to the first challenge by a particular antigen. Usually less extensive than the secondary immune response, being slower and shorter lived with smaller amounts of lower affinity antibody being produced. (18 Nov 1997) |
| hemic and immune systems | The organs involved in the production and functions of the blood and the cellular and molecular components providing defense against foreign organisms or substances. (12 Dec 1998) |
