| 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) |

Funchal, July 20th, 1888. Islets of Langerhans - collection of cells in the pancreas which produce insulin and glucagon. Cells of Langerhans - dendritic cells found in the epidermis of the skin.

| accelerated reaction | A response occurring in a shorter time than expected; the cutaneous manifestations occurring during the period between the second and tenth day following smallpox vaccination; because it is intermediate between a primary reaction and an immediate reaction, it is regarded as evidence of some degree of resistance. Synonym: vaccinoid reaction. (05 Mar 2000) |
| acid reaction | Any test by which an acid reaction is recognised such as the change of blue litmus paper to red, an excess of hydrogen ions over hydroxide ions in aqueous solution indicated by a pH value less than 7 (at 22캜). Compare: dissociation constant of water. (05 Mar 2000) |
| acute-phase reaction | <immunology, rheumatology> Refers to the changes in synthesis of certain proteins within the serum during an inflammatory response, which provides rapid protection for the host against microorganisms via non-specific defense mechanisms. It consists of fever, an increase in inflammatory humoral factors, and an increased synthesis by hepatocytes of a number of proteins or glycoproteins usually found in the plasma; the reaction is mediated by endogenous pyrogens, the hypothalamus, adrenal hormones, and other factors. (12 Jul 2000) |

| acute stress reaction | A sudden bout of anxiety that is often accompanied by the features of hyperventilation (tingling around mouth and in fingertips, rapid breathing, faintness or fainting). (27 Sep 1997) |
