| concentrated human red blood corpuscle | Corpuscle prepared from one or more preparations of whole human blood which are not more than 14 days old and each of which has already been directly matched with the blood of the intended recipient. (05 Mar 2000) |
| polioviruses, human 1-3 | Species of enterovirus which are the causal agents of poliomyelitis in humans. Three serotypes (strains) exist: brunhilde (type 1), lansing (type 2), and leon (type 3). Transmission is by the faecal-oral route, pharyngeal secretions, or mechanical vector (flies). Both inactivated and live attenuated vaccines have proven effective in combatting the infection. (12 Dec 1998) |
| coronavirus, human | A species of coronavirus causing respiratory and enteric diseases in humans. (12 Dec 1998) |
| health and human services | See HHS. (12 Dec 1998) |
| hepatitis, viral, human | Viral hepatitis in man. (12 Dec 1998) |
| herpes virus 1, human | The type species of simplexvirus causing most forms of non-genital herpes simplex in humans. Primary infection occurs mainly in infants and young children and then the virus becomes latent in the dorsal root ganglion. It then is periodically reactivated throughout life causing mostly benign conditions. (12 Dec 1998) |
| herpes virus 2, human | A species of simplexvirus associated with genital infections (herpes genitalis). It is transmitted by sexual intercourse and close personal contact. (12 Dec 1998) |
| herpes virus 3, human | The type species of varicellovirus causing chickenpox (varicella) and herpes zoster (shingles) in humans. (12 Dec 1998) |
| herpes virus 4, human | A species of lymphocryptovirus cultivated from cultures of burkitt lymphoma. It is thought to be the causative agent of infectious mononucleosis. (12 Dec 1998) |
| herpes virus 6, human | The type species of roseolovirus isolated from patients with aids and other lymphoproliferative disorders. It infects and replicates in fresh and established lines of haematopoietic cells and cells of neural origin. It also appears to alter nk cell activity. Hhv-6 (hblv) antibodies are elevated in patients with aids, sjogren's syndrome, sarcoidosis, chronic fatigue syndrome, and certain malignancies. Hhv-6 is the cause of exanthema subitum and has been implicated in encephalitis. (12 Dec 1998) |
| herpes virus 7, human | A species of the family herpesviridae isolated from activated, CD4-positive T-lymphocytes taken from the blood of a healthy human. (12 Dec 1998) |
| hormone, 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 the time of fertilization. It therefore forms the foundation of most common pregnancy tests. The level of hcg in maternal serum 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) |
