| human leukaemia-associated antigens | Antigen's on the surface of leukaemic cells which seem not to be present on the surfaces of the same type of normal cells; the myeloblast antigen of acute myelogenous leukaemia found in chronic myelogenous leukaemia is thought to be associated with a "blastic" transformation. (05 Mar 2000) |
| human leukocyte antigen | <immunology> A genetic fingerprint on white blood cells and platelets, composed of proteins that play a critical role in activating the bodys immune system to respond to foreign organisms. Acronym: HLA (16 Dec 1997) |
| human leukocyte-associated antigens | Proteins on the outer part of body cells that help fight illness. These proteins vary from person to person. Scientists think that people with certain types of HLA antigens are more likely to develop insulin-dependent diabetes.The HLA antigens are also responsible for histocompatibility reactions. (09 Oct 1997) |
| human lymphocyte antigen | A system designation for the gene products of at least four linked loci (A, B, C, and D) and a member of subloci on the sixth human chromosome which have been shown to have a strong influence on human allotransplantation, transfusions in refractory patients, and certain disease associations; more than 50 alleles are recognised, most of which are at loci HLA-A and HLA-B; autosomal dominant inheritance.

| human normal immunoglobulin | A preparation of the proteins of liquid human plasma, containing the antibodies of normal adults; it is obtained from pooled liquid human plasma from a number of donors and may be prepared by precipitation with organic solvents under controlled conditions of pH, ionic strength, and temperature. Synonym: human normal immunoglobulin. (05 Mar 2000) |
| human papilloma virus | <virology> A disease caused by the human papilloma virus characterised by a soft wart-like growth on the genitalia (for example penis, vulva). In adults this infection is most commonly transmitted sexually. Genital warts are very common and are increasing in incidence. Safe sex practices, such as using condoms can help decrease the risk of infection. Treatment includes several topical agents to eradicate the lesions, cryosurgery, laser therapy, electrocauterisation or surgical removal. See: alternate name condyloma acuminata. Acronym: HPV (27 Sep 1997) |
| human pertussis immune serum | The sterile serum prepared from the pooled blood of healthy adult human beings who have received repeated courses of phase I pertussis vaccine; administered intravenously or intramuscularly for the prophylaxis or treatment of whooping cough. (05 Mar 2000) |
| human plasma protein fraction | A sterile solution of selected proteins derived from the blood plasma of adult human donors, containing 4.5 to 5.5 g of protein per 100 ml, of which 83 to 90% is albumin and the remainder is alpha-and beta-globulins; used as a blood volume supporter. (05 Mar 2000) |
| human rights | The rights of the individual to cultural, social, economic, and educational opportunities as provided by society, e.g., right to work, right to education, and right to social security. (12 Dec 1998) |
