Adenomyosis uteri: Also known more succinctly as adenomyosis (pronounced ad-den-o-mi-o- sis), this is a common benign condition of the uterus in which the endometrium (the mucous membrane lining the inside of the uterus) grows into the myometrium (the uterine musculature located just outside the endometrium) The endometrium and myometrium under normal circumstances live adjacent to one another as discrete neighbors. In adenomyosis, the endometrium invades the myometrium. The myometrium may respond to this intrusion with muscular overgrowth. If an island of endometrial tissue is contained and circumscribed within the myometrium, it forms a nodule called an adenomyoma (plural: adenomyomata). Adenomyosis is made up of adeno (gland) + myo (muscle) +osis (a condition of) = a condition of glandular tissue (referring to the endometrium) in the muscle (the myometrium). Adenomyosis goes by several other names including endometriosis interna or uterina, and adenomyometritis.
Adenopathy: Large or swollen lymph nodes. Lymph nodes can become enlarged as a result of inflammatory diseases, infection, or cancer. Synonymous with lymphadenopathy.
Adenosine: A nucleoside containing adenine as its base. Adenosine acts to dilate the coronary arteries and is employed in the adenosine thallium scan of the heart.
- Adenosine deaminase (ADA)
Adenosine deaminase (ADA): An enzyme that plays a key role in salvaging purine molecules.
- Adenosine deaminase (ADA) deficiency
Adenosine deaminase (ADA) deficiency: A genetic (inherited) condition that results in a immune deficiency disorder called severe combined immunodeficiency disease. Adenosine deaminase is an enzyme that plays a key role in salvaging purine molecules. ADA deficiency is of special interest in the history of genetics. The first successful instance of gene therapy in humans was […]
- Adenosine thallium scan
Adenosine thallium scan: A method of examining the heart to obtain information about the blood supply to the heart muscle. Special cameras take a series of pictures of the heart. Radioactive sestamibi is injected into the bloodstream and serves as a tracer. The tracer attaches to certain cells and makes them visible to the special […]
