Age-related macular degeneration (AMD) is the leading cause of visual loss in individuals over 60 years old, in developed countries. This article provides the latest information about the role of retinal oxygen metabolism in origin of that disease. It is considered that reactive oxygen species (ROS), including free radicals are responsible for apoptotic(More)
The aim of the study was to assess in vitro the effect of electromagnetic field produced by mobile phones on the activity of superoxide dismutase (SOD-1) and the level of malonyldialdehyde (MDA) in human blood platelets. The suspension of blood platelets was exposed to the electromagnetic field with the frequency of 900 MHz for 1, 3, 5, and 7 min. Our(More)
Platelet is blood's morphotic element in which intense energy metabolism takes place, which makes it possible to participate in the complex processes of the organism's homeostasis. The aim of the study was to analyse aerobic metabolism in the platelets, taking into consideration lipids peroxidation in patients with bladder cancer treated with the bacillus(More)
The aim of the paper was to estimate in vitro the effect of electromagnetic field produced by mobile phones on the activity of superoxide dismutase (SOD-1) in human blood platelets. Suspension of blood platelets exposed to the electromagnetic field of 900 MHz frequency for 1, 3, 5, 7 minutes. Our studies demonstrated that microwaves produced by mobiles(More)
The investigation aimed at evaluating free supraoxide radicals generations and the degree of blood platelets cell membrane lipids peroxidation on the basis of supraoxide dismutase activity and the level of malonyl dialdehyde (MDA) after a 30-min exposure to mustard gas in vitro. The obtained results showed that blood platelets supraoxide dismutase activity(More)
Our investigations were carried out on human blood platelets obtained from persons aged 20-23, free from any systemic diseases. Drugs were incubated with blood platelets. Changes of antioxidant enzymes were detected. Glyceryl trinitrate increased the activity of Zn Cu-SOD (4.62%) and GPx (275.91%), concentration of ATP (13.01%) and the blood platelets(More)
