lipid peroxidation

Impact of anthropogenic pollution in Tyumen on herbs vital activity parameters

The purpose of this study was the investigation of lipid peroxidation products and photosynthetic pigment content in cells of herbs of various species in conditions of anthropogenic pollution of Tyumen. The material for the research was collected near different plants of Tyumen: metallurgical, engine, oil refinery, battery manufacturing as well as highway pollution. The following species of plants were analysed: coltsfoot (Tussilago farfara), red clover (Trifolium rubens), chamomile (Matricaria chamomilla) and wild vetch (Vicia cracca).

Influence of Probiotic “Bifidumbacterin” on the State of Large Intestine Microbiocenosis, Activity of the Antioxidant System and Processes of Lipid Peroxidation in the Conditions of Gentamycin-Associated Dysbiosis and Anomalous Characteristics of the Magn

Disturbances in the composition of microbiocenoses are warnings of changes in the physiological status of the organism, associated with the inhibition of immunobiological protection of the organism, its allergization, chronic intoxication, and increased susceptibility to infectious diseases. Some studies confirm the effect of magnetic radiation on abnormal characteristics both on the viability and growth rate of bacteria, and on the activity of various systems, in particular the antioxidant system and the lipid peroxidation system.

Lipid Peroxidation in Cucumber and Radish Seedlings Affected by Heavy Metals

The effect of heavy metal ions (Ni2+, Zn2+, Cu2+, Pb2+)  in concentrations of 10 μM, 0.1 μM and 1 mM on the rate of lipid peroxidation (LPO) has been studied in the 7-day-old seedlings of cucumber (Cucumis sativus L.) and radish (Raphanus sativus L.). It was revealed that Ni2+ and Cu2+ ions induced oxidative stress in plant cells, but Pb2+ and Zn2+ ions did not have toxic effects. The heavy metals effect on LPO increasing was as follows: Zn2+ < Pb2+< Ni2+ < Cu2+ for cucumber plants; Pb2+< Zn2+ < Cu2+ < Ni2+ for radish plants.

The Malondialdehyde Assessment in the Blood Serum of Ultrahigh Frequency Electromagnetic Field Exposed Animals

The goal of this research was lipid peroxidation process assessment for different levels of ultrahigh frequency electromagnetic field and different time exposure. There were animal 171 MHz one time exposures during 1 and 3 hours. In the blood serum of exposed animals the malondialdehyde concentration evaluated the lipid peroxidation process. The research results shown the statistically significant electromagnetic field biological effects as for maximum field strength 1 hour exposure, as lower field strength 3 hours exposure.

Experimental Study of Electromagnetic Fields the Meter Band Some Indicators of Oxidative Stress

The paper presents the results of an experimental study of VHF band electromagnetic field on the intensity of lipid peroxidation and total antioxidant activity of rats blood serum. As a result of the conducted research it were revealed valid changes in the concentration of diene conjugates, ketodienes and of the activity of the antioxidative system at different duration of exposure.
