| dental plaque | <dentistry> A soft, thin film of food debris, mucin and dead epithelial cells deposited on the teeth, providing the medium for the growth of various bacteria. The main inorganic components are calcium and phosphorus with small amounts of magnesium, potassium and sodium, the organic matrix consists of polysaccharides, proteins, carbohydrates, lipids and other components. Plaque plays an important aetiological role in the development of dental caries and periodontal and gingival diseases and provides the base for the development of materia alba, calcified plaque forms dental calculus.

|---|---|
| dental plaque index | An index which scores the degree of dental plaque accumulation. (12 Dec 1998) |
| fibrous plaque | Thickened area of arterial intima with accumulation of smooth muscle cells and fibrous tissue (collagen etc.) produced by the fat laden smooth muscle cells. Below the thickening may be free extracellular lipid and debris that, if much necrosis is also present, is referred to as an atheroma. (18 Nov 1997) |
| adhesion | 1. <chemistry> The property of remaining in close proximity, as that resulting from the physical attraction of molecules to a substance or the molecular attraction existing between the surfaces of contacting bodies. 2. The stable joining of parts to each other, which may occur abnormally. 3. A fibrous band or structure by which parts abnormally adhere. Origin: L. Adhaesio, from adhaerere = to stick to (15 Jan 1998) |
| adhesion dyspepsia | Pain, dyspepsia, and other symptoms alleged to result from perigastric adhesions. (05 Mar 2000) |
| adhesion molecules | Molecules that are involved in T helper-accessory cell, T helper-B-cell, and T cytotoxic-target cell interactions. (05 Mar 2000) |
| adhesion phenomenon | A phenomenon manifested by the adherence of antigen-antibody-complement complex to "indicator cells" (microorganisms, platelets, leukocytes, or erythrocytes), the reaction being sensitive and specific for the antigen and antibody in the complex. Synonym: erythrocyte adherence phenomenon, immune adherence phenomenon, red cell adherence phenomenon. (05 Mar 2000) |
| adhesion-related kinase | <chemical> New member of the immunoglobulin superfamily with 2 immunoglobulin-like domains Synonym: ark protein, ark receptor tyrosine kinase (26 Jun 1999) |

| bacterial adhesion | Physicochemical property of fimbriated (fimbriae, bacterial) and non-fimbriated bacteria of attaching to cells, tissue, and nonbiological surfaces. It is a factor in bacterial colonization and pathogenicity. (12 Dec 1998) |
| vascular cell adhesion molecule-1 | Cytokine-induced cell adhesion molecule present on activated endothelial cells, tissue macrophages, dendritic cells, bone marrow fibroblasts, myoblasts, and myotubes. It is important for the recruitment of leukocytes to sites of inflammation. (12 Dec 1998) |
| receptors, leukocyte-adhesion | Family of proteins associated with the capacity of leukocytes, including lymphocytes, monocytes, and neutrophils, to adhere to each other and to certain substrata, e.g., the c3bi component of complement. Members of this family are the lymphocyte function-associated antigen-1 (lfa-1), the macrophage-1 antigen (mac-1), and the antigen p150,95 or p150,95 leukocyte adhesion protein. They all share a common beta-subunit which is the CD18 antigen. All three of the above antigens are absent in inherited leukocyte-adhesion deficiency syndrome, which is characterised by recurrent bacterial infections, impaired pus formation, and wound healing as well as abnormalities in a wide spectrum of adherence-dependent functions of granulocytes, monocytes, and lymphoid cells.
