The faculty member in the College of Pharmacy, University of Al-Mustansiriyah, Dr. Ahmed Ali Muhammad conducted a study on the estimation of oxidative stress and antioxidants in patients with hydatid disease (echinococcosis). The study highlighted estimating and examining the level of both oxidative stress and antioxidants in a sample of people with hydatid disease in Iraq via biochemical analyzes. The study concluded that there was a clear increase in the level of Malone Di Aldehyde (MDA) coinciding with a decrease in the level of enzymes (SOD, GSH-Px, CAT, GST, GSH) in the erythrocytes of patients with cysts compared with their levels in healthy people, as well as the importance of These are laboratory parameters and their potential for use in disease diagnosis. The study demonstrated an increase in oxidative stress in patients with hydatid cysts, which confirms the need to use of antioxidants besides to anti-parasite drugs during treating patients.
