Another name for the human immunodeficiency virus (HIV), the cause of AIDS. HIV has also been called the human lymphotropic virus type III and the lymphadenopathy-associated virus and the lymphadenopathy virus. No matter what name is applied, it is a retrovirus. (A retrovirus has an RNA genome and a reverse transcriptase enzyme. Using the reverse transcriptase, the virus uses its RNA as a template for making complementary DNA which can integrate into the DNA of the host organism). Although the American research Robert Gallo at the National Institutes of Health believed he was the first to find HIV, it is now generally accepted that the French physician Luc Montagnier (1932-) and his team at the Pasteur Institute discovered HIV in 1983-84.
An X-ray of the lymphatic system for which a dye is injected to outline the lymphatic vessels and organs.
LAM is generally progressive, leading to increasingly impaired lung function. The rate of development can vary considerably among patients. As the disease advances, there is more extensive growth of muscle cells throughout the lung and repeated leakage of fluid into the chest cavity (pleural effusions). As an increasing number of cysts are formed, the lung […]
An abnormal structure that consists of a collection of blood vessels and lymph vessels that are overgrown and clumped together. Depending on its nature, a lymphangioma may grow slowly or quickly. Lymphangiomas can cause problems because of their location. For example, a lymphangioma around the larynx might cause a breathing problem.
The red streaking and gland (lymph node) swelling in the area of an injury especially on the extremities. It is usually caused by a bacterial infection with Streptococcus. The bacteria enter the body through a cut, scrape, bite or wound of some sort. The bacteria can get into the lymphatic system, which is part of […]
Pertaining to a small, thin channel that is similar to a blood vessel and that collects and carries tissue fluid (lymph) from the body. This fluid ultimately drains back into the bloodstream.
