Modified ESR‐based photosafety test (ESR‐PT) detecting singlet oxygen and free radical formation
Journal of Applied Toxicology, 2023AbstractThe electron spin resonance‐based photosafety test (ESR‐PT) was modified using a new parameter, photoreactivity index (PRI), to detect singlet oxygen and free radical photoproducts simultaneously. With this modification, the modified ESR‐PT is expected to reduce the number of false negative results due to chemicals producing free radical ...

Oxygen free radicals interact with indomethacin to cause gastrointestinal injury
Agents and Actions, 1986 In the present study it was shown that, unlikely MK447, a known oxygen free radical compound, PGE2 is much less effective against indomethacin-induced G.I. ulcers than against ethanol damage. It seems likely that factors other than PG deficiency (such as

Incidence of cardiovascular events is higher in hemodialysis (HD) patients than in general population. Oxidative stress represents a major specific risk factor of accelerated atheroma particularly in association with inflammation and malnutrition. The aim of our study is to evaluate a simple test of lipid peroxidation measurement using the "Free Oxygen

To observe the impact of Toxoplasma gondii infection on the level of oxygen free radicals and antioxidant enzyme in serum and testes of mice.40 BALB/c male mice were randomly divided into four groups. Five mice from each group were injected intraperitoneally with 2.5 x 10(3) tachyzoites of T. gondii, the others received PBS. Mice were sacrificed on the

Sulfur dioxide (SO2) and Asbest are frequently found at workplaces. They can induce airway and lung parenchymal injury. Alveolar macrophages (AM) play an important and decisive role in the damage of respiratory tissue. We evaluated the reactive oxygen intermediates (ROI) production of AM and peripheral blood mononuclear cells after exposure with SO2 ...
