| hepatitis, chronic | A collective term for a clinical and pathological syndrome which has several causes and is characterised by varying degrees of hepatocellular necrosis and inflammation. Specific forms of chronic hepatitis include autoimmune hepatitis (hepatitis, autoimmune), chronic hepatitis b (hepatitis b, chronic), chronic hepatitis c (hepatitis c, chronic), chronic hepatitis d (hepatitis d, chronic), indeterminate chronic viral hepatitis, cryptogenic chronic hepatitis and drug-related chronic hepatitis (hepatitis, chronic, drug-induced). (12 Dec 1998) |

| hepatitis, chronic, drug-induced | An inflammatory disease of the liver, lasting six months or more, and caused by an adverse drug effect. The adverse effect may result from a direct toxic effect of a drug or metabolite, or an idiosyncratic response to a drug or metabolite. The clinical and histological changes can mimic viral or autoimmune hepatitis. (12 Dec 1998) |
| hepatitis d, chronic | Inflammatory disease of the liver caused by hepatitis d virus in conjunction with hepatitis b virus and lasting six months or more. (12 Dec 1998) |
| Galton's delta | A more or less well-marked triangle, in a fingerprint, on either side where the straight ridges near the joint of the distal phalanx are succeeded by arches, loops, or whorls. See: Galton's system of classification of fingerprints. Synonym: triradius. (05 Mar 2000) |
| gene rearrangement, delta-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the delta-chain of antigen receptors. (12 Dec 1998) |
| genes, T-cell receptor delta | DNA sequences encoding the delta chain of the T-cell receptor. The delta-chain locus is located entirely within the alpha-chain locus. (12 Dec 1998) |
| receptors, antigen, T-cell, gamma-delta | T-cell receptors composed of CD3-associated gamma and delta polypeptide chains and expressed primarily in CD4-/CD8- T-cells. The receptors appear to be preferentially located in epithelial sites and probably play a role in the recognition of bacterial antigens. The T-cell receptor gamma/delta chains are separate and not related to the gamma and delta chains which are subunits of CD3 (see antigens, CD3). (12 Dec 1998) |
| receptors, opioid, delta | A class of opioid receptors recognised by its pharmacological profile. Delta opioid receptors bind endorphins and enkephalins with approximately equal affinity and have less affinity for dynorphins. (12 Dec 1998) |
