| ABO incompatibility | <haematology> A type of blood incompatibility, found rarely. Transfusion reactions may occur as a result of such incompatibility. (27 Sep 1997) |
|---|---|
| blood group incompatibility | A mismatch between donor and recipient blood. Antibodies present in the recipient's serum are directed against antigens in the donor product. Such a mismatch may result in a transfusion reaction in which, for example, donor blood is haemolyzed. (12 Dec 1998) |
| rhesus incompatibility | <haematology> A blood incompatibility between the mother and her baby. During childbirth if the mother is Rh negative and the baby is Rh positive, blood can enter the maternal circulation (from the baby) sensitising the mother against Rh factor. The mother's immune system will produce antibodies to Rh factor. In subsequent pregnancies, these maternal Rh antibodies can mix into the foetal circulation during childbirth. This will cause the rupture (haemolytic anaemia) of the baby's red blood cells. See: newborn jaundice. (27 Sep 1997) |
| physiologic incompatibility | A form of incompatibility in which the substances in a mixture exert opposing physiologic actions. Synonym: therapeutic incompatibility. (05 Mar 2000) |
| self incompatibility | <plant biology> Inability of pollen grains to fertilize flowers of the same plant or its close relatives. Acts as a mechanism to ensure out breeding within some plant species, for example in the case of the S gene complex in Brassicas. (18 Nov 1997) |
| drug incompatibility | <pharmacology> The quality of not being miscible with another given substance without a chemical change. One drug is not of suitable composition to be combined or mixed with another agent or substance. The incompatibility usually results in an undesirable reaction, including chemical alteration or destruction. (12 Dec 1998) |
| incompatibility | The quality of being incompatible. (05 Mar 2000) |
| therapeutic incompatibility | A form of incompatibility in which the substances in a mixture exert opposing physiologic actions. Synonym: therapeutic incompatibility. (05 Mar 2000) |
| physiological | Of or pertaining to physiology; relating to the science of the functions of living organism; as, physiological botany or chemistry. Source: Websters Dictionary (01 Mar 1998) |
| physiological adaptation | A peculiarity of the basic physical and chemical activities that occur in cells and tissues of a species, which results in it being better fitted to its environment (for example, ability to absorb nutrients under low oxygen tensions). (09 Oct 1997) |
| physiological anatomy | Anatomy studied in its relation to function. Synonym: morphophysiology, physiological anatomy. (05 Mar 2000) |
| physiological chemistry | The scientific study of the chemistry of living cells, tissues, organs and organisms. (09 Oct 1997) |
| physiological drives | Those drives such as hunger and thirst which stem from the biological needs of an organism. Synonym: primary drives. (05 Mar 2000) |
| physiological homeostasis | bernard-Cannon homeostasis |
| physiological intracranial calcification | <radiology> Pineal gland, habenular commisure, choroid plexus, dura, pacchionian bodies, basal ganglia and dentate nucleus (12 Dec 1998) |
