What is the medical term for lysis?

(LY-sis) In biology, lysis refers to the breakdown of a cell caused by damage to its plasma (outer) membrane. It can be caused by chemical or physical means (for example, strong detergents or high-energy sound waves) or by infection with a strain virus that can lyse cells.

What does mast mean in medical terminology?

Combining forms meaning the breast; the mastoid. Compare: mammo-, mazo- [G. mastos]

What is the meaning of lysis in biology?

The disintegration or rupture of the cell membrane, resulting in the release of cell contents or the subsequent death of the cell. (medicine) The gradual recovery or recuperation from an acute disease. (suffix: –lysis) Decomposition, breakdown or disintegration.

How does lysis occur?

Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane channels called aquaporins, which greatly facilitate the flow of water.

What is the purpose of lysis?

The word lysis comes from the greek word for “loosen.” Cell lysis is the process of rupturing the membrane or walls of a cell. The purpose of a cell lysis buffer is to use a chemical mixture to disrupt the exterior environment of a cell in a way that causes it to break open and release its contents.

What does cyst O mean in medical terms?

The combining form cysto- is used like a suffix meaning “cyst,” which is a scientific term for a bladder, sac, or vesicle. It is often used in scientific terms, especially in biology and pathology. The form cysto- comes from Greek kýstis, meaning “bag,” “pouch,” or “bladder.”

What happens when a mast cell reacts to irritation?

When a mast cell is injured, it releases strong chemicals, including histamine, into the tissues and blood. These chemicals are very irritating and cause itching, swelling, and fluid leaking from cells. They can also cause muscle spasm, leading to lung and throat tightening (as is found in asthma) and loss of voice.

What is the full meaning of lysis?

Destruction
Lysis: Destruction. Hemolysis is the destruction of red blood cells with the release of hemoglobin; bacteriolysis is the destruction of bacteria; etc. Lysis can also refer to the subsidence of one or more symptoms of an acute disease as, for example, the lysis of fever in pneumonia.

What happens after cell lysis?

Cell lysis is a common outcome of viral infection. It consists of a disruption of cellular membranes, leading to cell death and the release of cytoplasmic compounds in the extracellular space. Lysis is actively induced by many viruses, because cells seldom trigger lysis on their own.

What is the definition of tumor lysis syndrome?

What does the Greek word lysis mean in Greek?

Lysis (/ ˈlaɪsɪs / LY-sis; Greek λύσις lýsis, “a loosing” from λύειν lýein, “to unbind”) is the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic (that is, “lytic” / ˈlɪtɪk / LIT-ək) mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate.

Which is the best definition of cell lysate?

ly·ses (-sēz) 1. Biochemistry The dissolution or destruction of cells, such as blood cells or bacteria, as by the action of a specific lysin that disrupts the cell membrane. 2. Medicine The gradual subsiding of the symptoms of an acute disease.
