Epinephrine
|
D004837 |
[The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.

Epiphyses
|
D004838 |
[The head of a long bone that is separated from the shaft by the epiphyseal plate until bone growth stops. At that time, the plate disappears and the head and shaft are united.

Epiphyses, Slipped
|
D004839 |
[A complete or partial separation of the EPIPHYSES from the DIAPHYSES.

|
Epiregulin
|
D066260 |
[A member of the epidermal growth factor (EGF) family of peptide growth factors that is synthesized as a transmembrane protein which can be cleaved to release a soluble active form. Epiregulin has specificity for the EGF RECEPTOR and the ERBB-4 RECEPTOR.

|
Epiretinal Membrane
|
D019773 |
[A membrane on the vitreal surface of the retina resulting from the proliferation of one or more of three retinal elements: (1) fibrous astrocytes; (2) fibrocytes; and (3) retinal pigment epithelial cells. Localized epiretinal membranes may occur at the posterior pole of the eye without clinical signs or may cause marked loss of vision as a result of covering, distorting, or detaching the fovea centralis. Epiretinal membranes may cause vascular leakage and secondary retinal edema. In younger individuals some membranes appear to be developmental in origin and occur in otherwise normal eyes. The majority occur in association with retinal holes, ocular concussions, retinal inflammation, or after ocular surgery. (Newell, Ophthalmology: Principles and Concepts, 7th ed, p291)

Epirizole
|
D004840 |
[4-Methoxy-2-(5-methoxy-3-methylpyrazol-1-yl)-6-methylpyrimidine. A pyrimidinyl pyrazole with antipyretic, analgesic, and anti-inflammatory activity.
] |
|
Epirubicin
|
D015251 |
[An anthracycline which is the 4'-epi-isomer of doxorubicin. The compound exerts its antitumor effects by interference with the synthesis and function of DNA.

|
Episiotomy
|
D004841 |
[An incision of the posterior vaginal wall and a portion of the pudenda which enlarges the vaginal introitus to facilitate delivery and prevent lacerations.
] |
|
Episode of Care
|
D017050 |
[An interval of care by a health care facility or provider for a specific medical problem or condition. It may be continuous or it may consist of a series of intervals marked by one or more brief separations from care, and can also identify the sequence of care (e.g., emergency, inpatient, outpatient), thus serving as one measure of health care provided.

|
Epispadias
|
D004842 |
[A birth defect due to malformation of the URETHRA in which the urethral opening is above its normal location. In the male, the malformed urethra generally opens on the top or the side of the PENIS, but the urethra can also be open the entire length of the penis. In the female, the malformed urethral opening is often between the CLITORIS and the labia, or in the ABDOMEN.

|
Epistasis, Genetic
|
D004843 |
[A form of gene interaction whereby the expression of one gene interferes with or masks the expression of a different gene or genes. Genes whose expression interferes with or masks the effects of other genes are said to be epistatic to the effected genes. Genes whose expression is affected (blocked or masked) are hypostatic to the interfering genes.
, Changes in non-allelelic gene interactions. They contribute to GENETIC VARIATION.

Epistaxis
|
D004844 |
[Bleeding from the nose.

|
Epitestosterone
|
D004845 |
[The 17-alpha isomer of TESTOSTERONE, derived from PREGNENOLONE via the delta5-steroid pathway, and via 5-androstene-3-beta,17-alpha-diol. Epitestosterone acts as an antiandrogen in various target tissues. The ratio between testosterone/epitestosterone is used to monitor anabolic drug abuse.
] |
|
Epithalamus
|
D019261 |
[The dorsal posterior subdivision of the diencephalon. The epithalamus is generally considered to include the habenular nuclei (HABENULA) and associated fiber bundles, the PINEAL BODY, and the epithelial roof of the third ventricle. The anterior and posterior paraventricular nuclei of the thalamus are included with the THALAMIC NUCLEI although they develop from the same pronuclear mass as the epithalamic nuclei and are sometimes considered part of the epithalamus.

|
Epithelial Attachment
|
D004846 |
[A wedge-shaped collar of epithelial cells which form the attachment of the gingiva to the tooth surface at the base of the gingival crevice.
] |
|
Epithelial Cell Adhesion Molecule
|
D000071858 |
[A cell adhesion molecule that is expressed on the membranes of nearly all EPITHELIAL CELLS, especially at the junctions between intestinal epithelial cells and intraepithelial LYMPHOCYTES. It also is expressed on the surface of ADENOCARCINOMA and epithelial tumor cells. It may function in the MUCOSA through homophilic interactions to provide a barrier against infection. It also regulates the proliferation and differentiation of EMBRYONIC STEM CELLS.

|
Epithelial Cells
|
D004847 |
[Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.

Epithelial Sodium Channel Agonists
|
D062708 |
[Compounds that either stimulate the opening or prevent closure of EPITHELIAL SODIUM ION CHANNELS.
] |
|
Epithelial Sodium Channel Blockers
|
D062686 |
[A subclass of sodium channel blockers that are specific for EPITHELIAL SODIUM CHANNELS.
] |
|
Epithelial Sodium Channels
|
D053503 |
[Sodium channels found on salt-reabsorbing EPITHELIAL CELLS that line the distal NEPHRON; the distal COLON; SALIVARY DUCTS; SWEAT GLANDS; and the LUNG. They are AMILORIDE-sensitive and play a critical role in the control of sodium balance, BLOOD VOLUME, and BLOOD PRESSURE.
