A number of 42 healthy subjects constituted the non-exposed sample.<strong> </strong>The results of the study prove the presence of some significantly high concentrations in acute viral hepatitis compared to the non-exposed sample, for lipidic peroxides and also for carbonylated proteins.<strong> </strong>Although both markers show the existence of oxidative stress in hepatitis, it seems that lipidic peroxides represents a more sensitive marker than carbonylated proteins, being known that, in acute and chronic hepatitis, lipoperoxidation of cell  membranes is the first process started by reactive oxygen species excessive production, also having as a result the production of liver cell injury. The assessment of lipidic peroxides in dynamics, by its prolonged persistence, can become not only a diagnosis marker in acute viral hepatitis, but also a prognosis marker, useful in monitoring the evolution of hepatitis.</p>}, number={1, 2}, journal={Applied Medical Informatics}, author={MUNTEAN, Monica and BONDOR, Cosmina Ioana and ŢĂŢULESCU, Doina and ŢIGAN, Ştefan and MUREŞAN, Adriana}, year={2011}, month={Apr.}, pages={3–8} }
