| human chorionic gonadotropin | A human hormone made by chorionic cells (in the foetal part of the placenta), hcg is directed at the gonads and stimulates them. Hcg becomes detectable (by immunologic means) within days of fertilization and forms the foundation of the common pregnancy tests. The level of hcg in maternal serum also enters as one component in the double and the triple screens used during pregnancy to assign risks of down syndrome and other foetal disorders. (12 Dec 1998) |

| human clinical trial | <pharmacology> Controlled clinical studies in human volunteers to test the safety and efficacy of pharmaceutical candidates. There are usually three distinct phases of human clinical testing: Phases I, II, and III. Phase I trials are safety studies of volunteers, usually healthy controls. Phase II trials are studies to confirm safety and study optimum dose and initial efficacy. Phase III trials are studies to prove safety and efficacy in a specific patient population. (14 Nov 1997) |
| human cytomegalovirus | <virology> A group of viruses within the subfamily Cytomegalovirus (Betaherpesvirinae) (of the family Herpesviridae) which infects human beings. (09 Oct 1997) |

| human ehrlichiosis | A form of ehrlichiosis that presents clinically as a undifferentiated acute febrile illness characterised by fever, chills, diarrhoea, and headache, following tick bite(s), probably by the Lone Star Tick, Amblyomma americanum. Caused by Ehrlichia chaffeensis. First described in 1987. (Thought to be predominantly a monocytic form of ehrlichiosis.) (05 Mar 2000) |

| human fibrin foam | A dry artificial sponge of human fibrin prepared by clotting with thrombin a foam of a solution of human fibrinogen; the clotted foam is dried from the frozen state and heated; used as a topical anticoagulant. (05 Mar 2000) |
| human gamma globulin | 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 gene therapy | <molecular biology, technique> Insertion of normal DNA directly into cells to correct a genetic defect. (09 Oct 1997) |
