| heat-shock response element | <cell biology, protein> The nucleotide sequence, CNNGAANNTCCNG, which is in the promoter region of the heat-shock genes. When the animal is exposed to certain types of stress such as a sudden rise in temperature, the first thing that happens to activate these genes is the binding of the HSE by a transcriptional enhancer protein.

| protein shock | The systemic reaction following the parenteral administration of a protein. (05 Mar 2000) |
| protein shock therapy | The injection of a foreign protein to induce fever as a means of treating certain diseases. Synonym: foreign protein therapy. (05 Mar 2000) |
| pseudoanaphylactic shock | A reaction that is similar to anaphylactic shock, but which does not require the incubation period characteristic of induced sensitivity (anaphylaxis); it is unrelated to antigen-antibody reactions. Synonym: anaphylactoid crisis, pseudoanaphylactic shock. (05 Mar 2000) |
| high-energy shock waves | Compression waves of large amplitude, across which density, pressure, and particle velocity change drastically. (12 Dec 1998) |
| histamine shock | The shock state produced in animals by the injection of histamine; characterised by bronchiolar spasm in the guinea pig and constriction of hepatic veins in the dog. (05 Mar 2000) |
| septic shock | <microbiology> Condition of clinical shock caused by endotoxin in the blood. A serious complication of severe burns and abdominal wounds, frequently fatal. Part of the problem seems to be due to increased leucocyte adhesiveness, which leads to massive sequestration of neutrophils in the lung, increased vascular permeability and acute respiratory distress syndrome. (11 Jan 1998) |
| serum shock | Anaphylactic or anaphylactoid shock caused by the injection of antitoxic or other foreign serum. (05 Mar 2000) |
| shell shock | The World War I name for what is known today as posttraumatic stress, this is a psychological disorder that develops in some individuals who have had major traumatic experiences (and, for example, have been in a serious accident or through a war). The person is typically numb at first but later has symptoms including depression, excessive irritability, guilt (for having survived while others died), recurrent nightmares, flashbacks to the traumatic scene, and overreactions to sudden noises. Posttraumatic stress became known as such in the 70s due to the adjustment problems of some vietnam veterans. (12 Dec 1998) |
| shock | 1. <psychiatry> A sudden disturbance of mental equilibrium. 2. <cardiology> A condition of profound haemodynamic and metabolic disturbance characterised by failure of the circulatory system to maintain adequate perfusion of vital organs, it may result from inadequate blood volume (hypovolaemic shock), inadequate cardiac function (cardiogenic shock) or inadequate vasomotor tone (neurogenic shock, septic shock). (18 Nov 1997) |
| shock antigen | An antigen capable of producing anaphylactic shock in an animal that has been sensitised to it. (05 Mar 2000) |
| shock, cardiogenic | Shock caused by heart failure. The heart fails to pump blood effectively. For example, a heart attack (a myocardial infarction) can cause an abnormal ineffectual heart beat (an arhythmia) with very slow, rapid, or irregular contractions of the heart, impairing the heart's ability to pump blood, lowering the volume of blood going to vital organs. Cardiogenic shock can also be due to drugs that reduce heart function or an abnormally low level oxygen in the blood (hypoxaemia) caused, for instance, by lung disease. Whatever be the cause, blood vessels constrict and adrenalin-like substances are secreted into the bloodstream, increasing the heart rate. Treatment of cardiogenic shock is aimed at improving the heart's function. Shock after a heat attack is extremely serious. The mortality rate is over 80%. (12 Dec 1998) |
| shock, hypovolaemic | Shock due to a decrease in blood volume. This is the 1 cause of shock. It can be due to loss of blood from bleeding, loss of blood plasma through severe burns, and dehydration. The treatment, first and foremost, is prompt intravenous administration of fluid. (12 Dec 1998) |
| shock index | The quotient of the cardiac rate divided by the systolic blood pressure; normally approximately 0.5, but in shock (e.g., rising pulse rate with falling blood pressure), the index may reach 1.0. (05 Mar 2000) |
| shock lung | In shock, the development of oedema, impaired perfusion, and reduction in alveolar space so that the alveoli collapse. Synonym: pump lung, wet lung, white lung. (05 Mar 2000) |
