lysis

 [li´sis]
1. destruction, as of cells by a specific lysin.
2. decomposition, as of a chemical compound by a specific agent. See also degradation.
3. mobilization of an organ by division of restraining adhesions.
4. the gradual abatement of the symptoms of a disease.

ly·sis

(lī'sis),
1. Destruction of red blood cells, bacteria, and other structures by a specific lysin, usually referred to by the structure destroyed (for example, hemolysis, bacteriolysis, nephrolysis); may be due to a direct toxin or an immune mechanism, such as antibody reacting with antigen on the surface of a target cell, usually by binding and activation of a series of proteins in the blood with enzymatic activity (complement system).
2. Gradual subsidence of the symptoms of an acute disease, a form of the recovery process, as distinguished from crisis.
[G. dissolution or loosening]

lysis

/ly·sis/ (li´sis)
1. destruction or decomposition, as of a cell or other substance, under influence of a specific agent.
2. mobilization of an organ by division of restraining adhesions.
3. gradual abatement of the symptoms of a disease.

lysis

(lī′sĭs)
n. pl. 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.

lysis

[lī′sis]
Etymology: Gk, lysein, to loosen
1 destruction or dissolution of a cell or molecule through the action of a specific agent. Cell lysis is frequently caused by a lysin. lytic, adj.
2 gradual diminution in the symptoms of a disease. Compare crisis.
3 surgery performed to free adhesions of tissues. See also adhesiotomy. lyse, v.

lysis

Destruction of cells with release of contents. See Antibody-mediated lysis, Cytolysis, Follicle lysis, Hemolysis, NK-mediated lysis.

lysis

The destruction of a living cell by disruption of its membrane. Haemolysis is lysis of red blood cells. This will occur if the cells are placed in plain water.

lysis

the rupturing of a cell with release of its contents; for example, the bursting of a bacterial cell to release BACTERIOPHAGES, or HAEMOLYSIS - the bursting of a red blood cell (see RHESUS HAEMOLYTIC ANAEMIA).

lysis

enzyme-dependent destruction (liquefaction) of cells or tissues

lysis (lī´sis),

n the gradual abatement of the symptoms of a disease. The disintegration or dissolution of cells by a lysin.

2. mobilization of an organ by division of restraining adhesions.
3. gradual abatement of the clinical signs of a disease, e.g. lysis of a fever.
