| bee | 1. <zoology> An insect of the order Hymenoptera, and family Apidae (the honeybees), or family Andrenidae (the solitary bees) See Honeybee. There are many genera and species. The common honeybee (Apis mellifica) lives in swarms, each of which has its own queen, its males or drones, and its very numerous workers, which are barren females. Besides the A. Mellifica there are other species and varieties of honeybees, as the A. Ligustica of Spain and Italy; the A. Indica of India; the A. Fasciata of Egypt. The bumblebee is a species of Bombus. The tropical honeybees belong mostly to Melipoma and Trigona. 2. A neighborly gathering of people who engage in united labour for the benefit of an individual or family; as, a quilting bee; a husking bee; a raising bee. "The cellar . . . Was dug by a bee in a single day." (S. G. Goodrich) Pieces of hard wood bolted to the sides of the bowsprit, to reeve the fore-topmast stays through; called also bee blocks. <zoology> Bee beetle, a bird that eats the honeybee, as the European flycatcher, and the American kingbird. <botany> Bee flower, the larva of the bee beetle. To have a bee in the head or in the bonnet. To be choleric. To be restless or uneasy. To be full of fancies; to be a little crazy. "She's whiles crack-brained, and has a bee in her head." . Origin: AS. Beo; akin to D. Bij and bije, Icel. B, Sw. & Dan. Bi, OHG. Pini, G. Biene, and perh. Ir. Beach, Lith. Bitis, Skr. Bha. Source: Websters Dictionary (01 Mar 1998) |

| bee-eater | <zoology> A bird of the genus Merops, that feeds on bees. The European species (M. Apiaster) is remarkable for its brilliant colours. An African bird of the genus Rhinopomastes. Source: Websters Dictionary (01 Mar 1998) |

| bee sting | Stings from bees and other large stinging insects such as yellow jackets, hornets and wasps can trigger allergic reactions varying greatly in severity. Avoidance and prompt treatment are essential. In selected cases, allergy injection therapy is highly effective. (The three A's of insect allergy are Adrenaline, Avoidance and Allergist.) (12 Dec 1998) |
| bee sting kit | An emergency kit carried by those who have a history of sudden and severe allergic reactions to bee stings. The kit generally includes a antihistamine pill and a self-administered adrenaline injection. (27 Sep 1997) |
| bee toxin | The toxin delivered by a bee sting; contains three active principles: biogenic amines, active peptides, and certain hydrolytic enzymes. (05 Mar 2000) |
| bee venoms | Venoms obtained from apis mellifera (honey bee) and related species. They contain various enzymes, polypeptide toxins, and other substances, some of which are allergenic or immunogenic or both. These venoms were formerly used in rheumatism to stimulate the pituitary-adrenal system. (12 Dec 1998) |
| dog bee | A male or drone bee. Source: Websters Dictionary (01 Mar 1998) |
| drone bee | <zoology> The male of the honeybee; a drone. Source: Websters Dictionary (01 Mar 1998) |
| monocytes, activated killer | Monocytes made cytotoxic by ex vivo incubation with cytokines, especially interferon-gamma. Akm cells are used for adoptive immunotherapy in cancer patients. (12 Dec 1998) |
| natural killer cell | <haematology, immunology> A certain type of white blood cell that attacks tumour cells and infected body cells by binding to a tumour cell and releasing lethal chemicals. Natural killer cells are thought to play a key role in cancer prevention by killing abnormal cells before they multiply and grow. (16 Dec 1997) |
| natural killer cells | Large granular lymphocytes which do not express markers of either T or B-cell lineage. These cells do possess Fc receptors for IgG and can kill target cells using antibody-dependent cell-mediated cytotoxicity. NK cells can also use perforin to kill cells in the absence of antibody. Killing may occur without previous sensitization. Synonym: NK cells. (05 Mar 2000) |
| natural killer cell stimulating factor | <cytokine> A 75 kD heterodimeric cytokine composed of disulfide-bonded 40 kD and 35 kD subunits that was originally identified by its ability to induce cytotoxic effector cells in synergy with less than optimal concentrations of interleukin-2. It is released by macrophages in response to infection and promotes the activation of cell-mediated immunity. Specifically, IL-12 triggers the maturation of Thl CD4 cells, specific cytotoxic T-lymphocyte responses and an increase in the activity of NK cells and consequently, it is the initiator of cell-mediated immunity. It enhances the lytic activity of NK cells, induces interferon production, stimulates the proliferation of activated T-cells and NK cells. Is secreted by human B lymphoblastoid cells (NC 37). May play a role in controlling immunoglobulin isotype selection as it also inhibits IgE synthesis (even in the presence of anti-IFN monoclonal antibody) and as a growth factor for activated CD4+ and CD8+ T-cells independently of interleukin-2, and for CD56+ NK cells but not resting peripheral blood mononuclear cells or resting or activated tonsillar B-cells. It is likely that interleukin 12 has a major role in protective immunity against viruses and is under study as an immunotherapy in HIV infection. Formerly referred to as cytotoxic lymphocyte maturation factor. Acronym: IL-12 (12 Dec 1998) |
| nine-killer | <zoology> The northern butcher bird. Origin: So called because it is believed to kill and impale on thorns nine birds, etc, in succession. Source: Websters Dictionary (01 Mar 1998) |
| killer | 1. One who deprives of life; one who, or that which, kills. 2. <zoology> A voracious, toothed whale of the genus Orca, of which several species are known. The killers have a high dorsal fin, and powerful jaws armed with large, sharp teeth. They capture, and swallow entire, large numbers of seals, porpoises, and dolphins, and are celebrated for their savage, combined attacks upon the right whales, which they are said to mutilate and kill. The common Atlantic species (Orca gladiator), is found both on the European and the American coast. Two species (Orca ater and O. Rectipinna) occur on the Pacific coast.
