HAEMOLYTIC [7 records]

Record 1 2011-01-07

English

Subject field(s)
  • Blood
  • Symptoms (Medicine)
DEF

A condition in which there are abnormally thick, almost spherical, red blood cells or spherocytes in the blood. This is seen most commonly in haemolytic spherocytic anaemia and acholuric jaundice.

French

Domaine(s)
  • Sang
  • Symptômes (Médecine)
CONT

La maladie de Minkowski-Chauffard ou sphérocytose héréditaire [est] une anémie hémolytique constitutionnelle liée à une anomalie de la membrane érythrocytaire. [Elle] est caractérisée par la présence de sphérocytes, c'est-à-dire des hématies denses, de petit diamètre, sans pâleur centrale, qui ont perdu leur forme biconcave pour devenir sphérique.

Record 2 2005-02-08

English

Subject field(s)
  • Animal Diseases
  • Blood
OBS

haemolytic. Relating to haemolysis.

OBS

haemolysis. The destruction of red blood corpuscles and the consequent escape from them of haemoglobin. It occurs gradually in some forms of anaemia and rapidly in poisoning by snake venom. Some chemical and bacterial toxins cause haemolysis.

OBS

anaemia. Refers to a deficiency of red cells or of haemoglobin.

French

Domaine(s)
  • Maladies des animaux
  • Sang
DEF

Anémie due à une destruction excessive des hématies.

Record 3 2004-05-19

English

Subject field(s)
  • Biological Sciences
  • Microbiology and Parasitology
  • Biochemistry
DEF

A toxin released by a bacterium into the medium in which it grows. Frequently very toxic, e. g. neurotoxins which destroy cells of the nervous system, haemolytic toxins which lyse red blood cells.

French

Domaine(s)
  • Sciences biologiques
  • Microbiologie et parasitologie
  • Biochimie
DEF

Substance toxique soluble produite par certains micro-organismes et trouvées dans leur milieu de croissance.

CONT

L'exotoxines sont sécrétées vers l'extérieur et diffusent dans le milieu ambiant. Elles provoquent dans l'organisme des lésions variées

Spanish

Campo(s) temático(s)
  • Ciencias biológicas
  • Microbiología y parasitología
  • Bioquímica
DEF

Toxina difundida al medio por bacterias vivas.

Record 4 1993-03-22

English

Subject field(s)
  • Immunology
DEF

Hypersensitivity caused by antibody to cell surface antigens. These can sensitize the cells for antibody-dependent cell-mediated cytotoxicity by K cells, or complement mediated lysis. Type II hypersensitivity is seen in the destruction of red blood cells in transfusion reactions, and in haemolytic disease of the newborn. The destruction of tissue in auto-immune diseases such as myathenia gravis is partly antibody-mediated.

French

Domaine(s)
  • Immunologie
DEF

Réaction d'immunité humorale. La combinaison antigène-anticorps ou haptène-anticorps détruit la cellule sur laquelle elle se fixe. Les anticorps sont des IgG ou des IgM; le complément peut intervenir dans ce processus; la réaction est précoce. En clinique, certaines anémies hémolytiques, agranulocytoses, thrombopénies et glomérulonéphrites sont dues à la réaction de type II.

Record 5 1993-01-23

English

Subject field(s)
  • Immunology
DEF

An autoantibody that is active only at temperature below 37 ° C.

CONT

Autoimmune haemolytic anemias.(...) Cold-reactive autoantibodies are often present in higher titres than the warm-reactive autoantibodies. The antibodies are primarily IgM and fix complement strongly. In most cases they are specific for the Ii blood group system.

French

Domaine(s)
  • Immunologie
CONT

La majorité des autoanticorps froids de classe IgM reconnaissent l'antigène public I. (...) Les autoanticorps anti-I de classe IgM ne se fixent sur les hématies qu'à basse température (4 ° C) et non à la température du corps. Cette particularité n'est pas liée à une modification de l'autoanticorps IgM par la température mais aux propriétés particulières de la membrane érythrocytaire au froid comme le démontre la réactivité identique de l'anticorps à 0 ° C et à 37 ° C avec l'antigène I purifié.

CONT

Anémie hémolytique à auto-anticorps "froids" (...)

Record 6 1989-11-27

English

Subject field(s)
  • Bioengineering
  • Microbiology and Parasitology
CONT

Streptococcal grouping sera, diluted and absorbed to remove cross-reactions, were bound to staphylococci and used to group trypsinised beta-haemolytic streptococci by coagglutination. The results compared well with those obtained using the Phadebact streptococcal grouping kit. The same sera bound to staphylococci without prior dilution and absorption could be used to group enzyme extracts of haemolytic streptococci by slide agglutination, the results again comparing favourably with those of the Phadebact kit.

OBS

This example was excerpted from the Medline data base

French

Domaine(s)
  • Technique biologique
  • Microbiologie et parasitologie
DEF

Méthode de coagglutination sur lame utilisée pour l'identification des streptocoques Bêta-hémolytiques, qui permet le groupage des streptocoques A, B, C et G. Elle permet également d'effectuer soit une agglutination directe à partir des colonies, soit une agglutination à partir de subcultures en bouillon de Todd-Hewitt.
