Hemolysis is attributed to somatic mutations in the PIG-A gene responsible for the formation of the glycosylphosphatidylinositol (GPI) anchor, that binds CD 59 and CD 55 to the membrane surface. Their absence from the red cell leads to hemolysis whenever complement is activated. PIG-A gene mutations are not sufficient per se for the development of PNH. The history of PNH is a fascinating story depicting the development of our knowledge of the disease since the first clinical description by Paul Strübing in 1882 till the elucidation of the hemolysis on the molecular level. The article describe the historical steps of this process. The pathogenesis of PNH has been significantly elucidated in the last years, but many questions remain to be clarified.</p>","PeriodicalId":79548,"journal":{"name":"Acta medica (Hradec Kralove).

Biological monitoring is based on determination of biological markers of exposure which are presented as the quantity of a chemical substance or its metabolites or as the deviation of biological parameters (enzyme activity etc.) induced by this substance in exposed humans. The greatest advantage of biological monitoring is the fact that the biological marker of exposure is more directly related to the adverse effects than any environment measurement. Another advantage of biological monitoring is based on the reality that the nonoccupational background exposure (leisure activity, residency, dietary habits, smoking, etc.) may also be expressed in the biological level. Biological parameters can be unfortunately affected by various factors that influence the fate of xenobiotic in vivo. The \"BEL\" (BTV-biological tolerance value for occupational exposures) is defined as the maximum permissible quantity of a chemical substance or its metabolites or the maximum permissible deviation from the norm of biological parameters during or after exposure.
