| eisenmenger complex | Defect of the interventricular septum with severe pulmonary hypertension, hypertrophy of the right ventricle, and latent or overt cyanosis. (12 Dec 1998) |
|---|---|
| Eisenmenger's complex | The combination of ventricular septal defect with pulmonary hypertension and consequent right-to-left shunt through the defect, with or without an associated overriding aorta. Synonym: Eisenmenger's defect, Eisenmenger's disease, Eisenmenger's tetralogy. (05 Mar 2000) |
| Electra complex | Female counterpart of the Oedipus complex in the male; a term used to describe unresolved conflicts during childhood development toward the father which subsequently influence a woman's relationships with men. Synonym: father complex. Origin: Electra, daughter of Agamemnon (05 Mar 2000) |
| electrocardiographic complex | <cardiology, physiology> A deflection or group of deflections in the electrocardiogram. (05 Mar 2000) |
| TLa complex | <molecular biology> Genes coding for and controlling TL antigens, the complex is situated close to the H 2 complex on mouse chromosome 17 and resembles H 2 in several ways. (18 Nov 1997) |
| enzyme-substrate complex | A noncovalent complex of two molecules; often referring to the enzyme-substrate complex in an enzyme-catalyzed reaction. Compare: central complex, Michaelis complex. Synonym: enzyme-substrate complex. (05 Mar 2000) |
| epilepsy, complex partial | Epileptic seizures that are episodic changes in behaviour in which an individual loses conscious contact with the environment. The onset of such seizures involves any of a variety of auras: deja-vu, an unusual smell, a sudden intense emotional feeling, a sensory illusion such as micropsia (objects growing smaller) or macropsia (objects growing larger), or other sensory hallucination. There may be a cessation of activity with some minor motor activity such as lip smacking, walking aimlessly, or other automatisms. The seizures may also be accompanied by the unconscious performance of highly skilled activities such as driving a car. When the seizure ends, the individual is amnesic for events that took place during the seizure and may take minutes or hours to recover fully to consciousness. (12 Dec 1998) |
| triple symptom complex | <syndrome> A multisystem, chronic recurrent disease characterised by ulceration in the mouth and genitalia, iritis, uveitis, arthritis and thrombophlebitis. Often treated with immunosuppressive therapy (corticosteroids, chlorambucil). (27 Sep 1997) |
| equiphasic complex | A diphasic complex whose positive and negative deflections are approximately equal. Synonym: equiphasic complex. (05 Mar 2000) |
| j-g complex | A complex consisting of the juxtaglomerular cells, which are modified smooth muscle cells in the wall of the afferent glomerular arteriole and sometimes also the efferent arteriole; extraglomerular mesangium lacis cells, which are located in the angle between the afferent and efferent glomerular arterioles; the macula densa of the distal convoluted tubule; and granular epithelial peripolar cells located at the angle of reflection of the parietal to the visceral capsule of the renal corpuscle; believed to provide some feedback control of extracellular fluid volume and glomerular filtration rate. Synonym: j-g complex, juxtaglomerular apparatus. (05 Mar 2000) |
| Jocasta complex | A mother's libidinous fixation on a son. Origin: Jocasta, mother and wife of Oedipus (05 Mar 2000) |
| junctional complex | The attachment zone between epithelial cells, typically consisting of the zonula occludens, the zonula adherens, and the macula adherens (desmosome). (05 Mar 2000) |
| juxtaglomerular complex | A complex consisting of the juxtaglomerular cells, which are modified smooth muscle cells in the wall of the afferent glomerular arteriole and sometimes also the efferent arteriole; extraglomerular mesangium lacis cells, which are located in the angle between the afferent and efferent glomerular arterioles; the macula densa of the distal convoluted tubule; and granular epithelial peripolar cells located at the angle of reflection of the parietal to the visceral capsule of the renal corpuscle; believed to provide some feedback control of extracellular fluid volume and glomerular filtration rate. Synonym: j-g complex, juxtaglomerular apparatus. (05 Mar 2000) |
