| haemoconcentration | Decrease in the volume of plasma in relation to the number of red blood cells; increase in the concentration of red blood cells in the circulating blood. (05 Mar 2000) |
|---|---|
| haemoconia | Small refractive particles in the circulating blood, probably lipid material associated with fragmented stroma from red blood cells. Synonym: blood dust, blood motes, dust corpuscles. Origin: haemo-+ G. Konis, dust (05 Mar 2000) |
| haemoconiosis | A condition in which there is an abnormal amount of haemoconia in the blood. (05 Mar 2000) |
| haemocryoscopy | Determination of the freezing point of blood. Origin: haemo-+ G. Kryos, cold, + skopeo, to examine (05 Mar 2000) |
| haemocuprein | Former terms for copper-containing proteins found in human erythrocytes and other tissues. See: superoxide dismutase, ceruloplasmin. Synonym: cerebrocuprein, erythrocuprein, haemocuprein, hepatocuprein. (05 Mar 2000) |
| haemocyanin | <chemical> Blue, oxygen transporting, copper containing protein found in the blood of molluscs and crustacea. A very large protein with 20-40 subunits and molecular weight of 2-8 million and having a characteristic cuboidal appearance under the electron microscope. Prior to the introduction of immunogold techniques, it was used for electron microscopic localisation by coupling to antibody. (18 Nov 1997) |
| haemocyte | <haematology> Blood cell, associated with a haemocoel, particularly those of insects and crustacea. Despite the name they are more leucocyte like, being phagocytic and involved in defence and clotting of haemolymph and not involved in transport of oxygen. (18 Nov 1997) |
| haemocytes | Any blood or formed element especially in invertebrates. (12 Dec 1998) |
| haemocytoblast | A blood cell derived from embryonic mesenchyme, characterised by basophilic cytoplasm and a relatively large nucleus with a spongy, loose network of chromatin and several nucleoli; mitochondria are extremely fine and delicate. Haemocytoblasts represent the primitive stem cells of the monophyletic theory of the origin of blood and have the potentiality of developing into erythroblasts, young forms of the granulocytic series, megakaryocytes, etc. Synonym: haematocytoblast, haemoblast. Origin: haemo-+ G. Kytos, cell, + blastos, germ (05 Mar 2000) |
| haemocytoblastoma | <oncology, tumour> A haemocytoblastoma is a tumour made up of cells from bone marrow. (09 Oct 1997) |
| haemocytocatheresis | Haemolysis, or other type of destruction of red blood cells. Origin: haemo-+ G. Kytos, a hollow (cell), + kathairesis, destruction (05 Mar 2000) |
| haemocytolysis | <haematology> Haemocytolysis is the process of dissolving blood cells. Origin: Gr. Lysis = dissolution (09 Oct 1997) |
| haemocytoma | <oncology, tumour> A haemocytoma is a tumour made up of undifferentiated blood cells. (09 Oct 1997) |
| haemocytometer | <instrument, microscopy> A glass slide with a chamber for counting blood corpuscles in a given volume. The cells are 0.1 mm deep and are made with several types of ruling. Such cells are convenient counting chambers for many other kinds of suspensions. (05 Aug 1998) |
| haemocytometry | The counting of red blood cells. (05 Mar 2000) |
