| exercise-induced amenorrhoea | The temporary cessation of menstrual function due to strenuous, daily exercise, as in jogging; increased endorphins inhibiting hypothalamic function. (05 Mar 2000) |

| familial fat-induced hyperlipaemia | Hyperlipoproteinaemia characterised by the presence of large amounts of chylomicrons and triglycerides in the plasma when the patient has a normal diet, and their disappearance on a fat-free diet; low alpha-and beta-lipoproteins on a normal diet, with increase on fat-free diet; decreased plasma postheparin lipolytic activity; and low tissue lipoprotein lipase activity. It is accompanied by bouts of abdominal pain, hepatosplenomegaly, pancreatitis, and eruptive xanthomas; autosomal recessive inheritance. See: familial lipoprotein lipase inhibitor. Synonym: Burger-Grutz syndrome, familial fat-induced hyperlipaemia, familial hyperchylomicronaemia, familial hypertriglyceridemia, idiopathic hyperlipaemia. (05 Mar 2000) |
| lens-induced uveitis | Intraocular inflammation occurring after extracapsular cataract extraction;probably an immune reaction to the patient's liberated lenticular proteins. Synonym: lens-induced uveitis. (05 Mar 2000) |
| leucine-induced hypoglycaemia | Rare cause of hypoglycaemia occurring following ingestion of leucine. Seen especially in infants. (05 Mar 2000) |
| ligand induced endocytosis | The formation of coated pits and then coated vesicles as a consequence of the interaction of ligand with receptors, which then interact with clathrin and associated proteins (coatomers) on the cytoplasmic face of the plasma membrane and come together to form a pit. Not all coated vesicle uptake of receptors requires receptor occupancy. (18 Nov 1997) |
| abscopal effect | A reaction produced following irradiation but occurring outside the zone of actual radiation absorption. (05 Mar 2000) |
| additive effect | <biochemistry, chemistry> An additive effect is the overall biological effect two chemicals acting together and which is the simple sum of the effects of the chemicals acting independently. Compare: antagonism. (15 Jan 1998) |
| adverse effect | This is an abnormal or harmful effect to an organism caused by exposure to a chemical. It is indicated by some result such as death, a change in food or water consumption, altered body and organ weights, altered enzyme levels, or visible illness. An effect may be classed as adverse if it causes functional or anatomical damage, causes irreversible change in the homeostasis of the organism, or increases the susceptibility of the organism to other chemical or biological stress. A non-adverse effect will usually be reversed when the organism is no longer being exposed to the chemical. (09 Oct 1997) |
| Anrep effect | A small transient positive inotropic effect of abrupt increases of systolic aortic and left ventricular pressures related to recovery from transient subendocardial ischemia (e.g., cold pressor test). (05 Mar 2000) |
| antagonistic effect | This is the consequence of one chemical (or group of chemicals) counteracting the effects of another chemical, the opposing chemicals cancel out each other's effects. (09 Oct 1997) |
| Arias-Stella effect | Focal, unusual, decidual changes in endometrial epithelium, consisting of intraluminal budding, and nuclear enlargement and hyperchromatism with cytoplasmic swelling and vacuolation; may be associated with ectopic or uterine pregnancy. Synonym: Arias-Stella effect, Arias-Stella reaction. (05 Mar 2000) |
| Auger effect | <physics> Transition of an electron in an atom from a discrete electronic level to an ionised continuous level with the same energy. Synonym: autoionisation. (13 Jan 1998) |
| autokinetic effect | In psychology, the apparent drifting about of a small, fixed, spot of light which is being observed in a dark room. (05 Mar 2000) |
| Bernoulli effect | <physics> The decrease in fluid pressure that occurs in converting potential to kinetic energy when motion of the fluid is accelerated, in accordance with Bernoulli's law. Applied in water aspirators, atomisers, and humidifiers in which a gas is accelerated across the end of a narrow, fluid-filled orifice. (05 Mar 2000) |
| Bohr effect | <physiology> Decrease in oxygen affinity of haemoglobin when pH decreases or concentration of carbon dioxide increases. (18 Nov 1997) |
