| Ehrlich's diazo reaction | The reaction of diazotised sulfanilic acid with bilirubin to form azobilirubin, which forms the basis of quantitating the amount of bilirubin in biological fluids. See: van den Bergh's test. Synonym: Ehrlich's diazo reaction. (05 Mar 2000) |

| Ehrlich's inner body | A round oxyphil body found in the red blood cell in case of haemocytolysis due to a specific blood poison. Synonym: Heinz-Ehrlich body. (05 Mar 2000) |
| Ehrlich's phenomenon | The difference between the amount of diphtheria toxin that will exactly neutralise one unit of antitoxin and that which, added to one unit of antitoxin, will leave one lethal dose free is greater than one lethal dose of toxin; i.e., it is necessary to add more than one lethal dose of toxin to a neutral mixture of toxin and antitoxin to make the mixture lethal (the basis of the L+ dose). (05 Mar 2000) |
| Ehrlich's postulate | Ehrlich postulated that cells contained surface extensions or side chains (haptophores) that bind to the antigenic determinants of a toxin (toxophores); after a cell is stimulated, the haptophores are released into the circulation and become the antibodies. See: receptor. Synonym: Ehrlich's postulate. (05 Mar 2000) |

| Ehrlich, Paul | <person> A brilliant scientist and student, born in Silesia, Germany, who at the age of 23 published his first scientific paper which was on the discovery of the mast cells - a name coined by him (1887). While a resident in medicine at Charite Hospital in Berlin he utilised the newly discovered aniline dyes to develop some of the basic methods of histology. Among his contributions are: The preparation and staining of blood smears, he demonstrated granules in leukocytes, described the neutrophil, basophil, eosinophil, myelocyte, and mononuclear cells (white blood cells), he demonstrated normoblasts, megaloblasts and microblasts of the erythrocytic (red blood cell) series. In 1887, he differentiated lymphocytic leukaemia from "bone marrow leukaemia" (myeloid) on blood smear, in 1888, he described aplastic anaemia, in 1882 the diazo reaction of typhoid urines, in 1882, less than six weeks after Koch described the Tuberculus bacillus, Ehrlich had described its acid-fastness and devised the fuchsin stain to demonstrate the pink rod on a blue background. Ehrlich fell ill with tuberculosis and went to Egypt for 3 years for rest and cure. Following his return, he entered the field of immunology. at Von Behring's request, he developed means of standardising antitoxin dosage (immunization units). at the age of 42, he became director of the "Royal Institute for Standardisation and Investigation of Antitoxic Sera." Here he devised his famous "side-chain" theory of immunisation. It has since been replaced. Paul Ehrlich reinvestigated Bordet's alexin and heat-stable substance and named them "complement" and "immune body". Ehrlich coined the terms and created a new science of chemotherapy. In 1910 he discovered Salvarsan or 606, a therapeutic antiluetic. For his silver bullet (Salvarsan) in 1908, he received the Nobel Prize. This scientist was greatly concerned over the problem of drug fastness which still remains a problem. He died August 20, 1915. Lived: 1854-1915. (18 Nov 1997) |

| Ehrlichia canis | The species causing the tick borne disease canine ehrlichiosis in dogs (transmitted by the tick Rhipicephalus sanguineus); it is the type species of the genus Ehrlichia. Occasionally causes tick borne infection in humans. (05 Mar 2000) |
| ehrlichia chaffeensis | A species of gram-negative bacteria that is the causative agent of human ehrlichiosis. This organism was first discovered at fort chaffee, arkansas, when blood samples from suspected human ehrlichiosis patients were studied. (12 Dec 1998) |

| Ehlers-Danlos s. |
1. a group of inherited disorders of the connective tissue, occurring in at least ten types, I to X, based on clinical, genetic, and biochemical evidence, varying in severity from mild to lethal, and transmitted genetically as autosomal recessive, autosomal dominant, or X-linked recessive traits. The major manifestations include hyperextensible skin and joints, easy bruisability, friability of tissues with bleeding and poor wound healing, calcified subcutaneous spheroids, and pseudotumors; variably present in some types are cardiovascular, gastrointestinal, orthopedic, and ocular defects. The biochemical defects are known for several types. Type IV, with prominent vascular manifestations, is caused by defects in the structure, synthesis, or secretion of one type of procollagen; type VI, with prominent ocular manifestations, is caused by a deficiency of lysyl hydroxylase; type VII, with multiple joint dislocations, is called also arthrochalasis multiplex congenita and is caused by mutations involving the normal cleavage sites of some procollagen chains; type IX is X-linked cutis laxa; and type X is due to a defect in fibronectin that interferes with normal platelet aggregation. See accompanying illustration. 2. cutaneous asthenia (def. 1).
