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

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).
