| human a1-proteinase inhibitor | A glycoprotein that is the major protease inhibitor of human serum, is synthesised in the liver, and is genetically polymorphic due to the presence of over 20 alleles; individuals appropriately homozygous are deficient in a1-trypsin and are predisposed to pulmonary emphysema and juvenile hepatic cirrhosis because of alterations in the amino acid and sialic acid components of the glycoprotein. A1-Antitrypsin also inhibits thrombin. Synonym: a1-trypsin inhibitor, human a1-proteinase inhibitor. (05 Mar 2000) |

| human babesiosis | A rare human disease caused by infection with Babesia species (most frequently B. Divergens in Europe and B. Microti in the U.S.) that has been fatal in some splenectomised individuals. (05 Mar 2000) |
| human body | The human being as a non-anatomical and non-zoological entity. The emphasis is on the philosophical or artistic treatment of the human being, and includes lay and social attitudes toward the body in history. (12 Dec 1998) |
| human botfly | A large, blue, brown-winged species whose larvae develop in open boil-like lesions in the skin of humans, many domestic animals, and some fowl. It is a very serious and damaging cattle parasite and frequently attacks small children in Central and South America. Its eggs are laid on the legs or abdomen of another insect, such as the mosquito; the eggs later hatch, when stimulated by warmth or other factors, to release the botfly larvae on the skin of the mosquito's bloodmeal host, and the larvae quickly invade the skin to initiate myiasis. Synonym: Dermatobia cyaniventris, human botfly, skin botflies, warble botfly. (05 Mar 2000) |
| human botfly myiasis | Infection of man and animals with larvae of the fly Dermatobia hominis. Synonym: human botfly myiasis. (05 Mar 2000) |
| human chorionic gonadotrophin | <hormone, tumour marker> A hormone that is produced by the developing placenta and by the fertilized egg after implantation in the uterine wall. This hormone is measured in the blood to determine pregnancy. Human chorionic gonadotrophin increases in quantity through the first trimester of pregnancy and begin to taper off after 85 days. Serum human chorionic gonadotrophin testing is accurate 48 hour post conception. Urine human chorionic gonadotrophin testing is a popular method of home pregnancy determination as human chorionic gonadotrophin can be detected in urine. Acronym: HCG (18 Nov 1997) |
| 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) |
