| Summary: | Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Katarína Fabšíková Supervisor: Prof. Ing. Vladimír Wsól, Ph.D. Title of diploma thesis: Effect of vitamin E on oxidative stress and the basement membrane in lungs in vitamin A-deficient rats In the experiment described in this thesis there was being observed the effect of long-term deficiency of vitamin A on the basement membrane in rat lungs. Rats were divided during the experiment into several groups differing in composition of feed and the changes of pulmonary basement membrane were being observed. Consequently, the effect of vitamin E and retinoic acid on membrane modifications was watched, too. During the experiment there was evaluated the rate of oxidative stress by the medium of glutathione and malondialdehyde levels, which act as its markers. These levels in all experimental animals were specified by HPLC chromatography. Also, the oxidative stress was assessed using other markers such as thickness of the basement membrane, deposits of collagen fibers and levels of retinol and α-tocopherol in plasma and tissues. This experiment should confirm the important role of vitamins acting as antioxidants in prevention and treatment of pathological changes caused by increased oxidative...
