Lipid oxidation can be evaluated in a variety of ways, such as the determination of peroxide value (PV), carbonyl compounds (malondialdehyde, hexanal, etc.) diene conjugation, and oxygen consumption. Various methods may be used to quantify the lipid oxidation such as iodometric titration (IT), UV-visible spectroscopy (ferrous oxidation method, iodide oxidation method), chromatography, CL, or fluorescence (FL) methods. [Pg.624]

Hydroquinone (1-10 (.miol/L) induced fluorescence from 2. 7 -dichlorofluorcscin acetate in HL-60 human leukaemia cells this was interpreted to indicate intracellular generation of hydrogen peroxide and other peroxides (Hiraku Kawanishi, 1996). Hydroquinone (200 mg/kg bw, as a single oral dose) administered to male Sprague-Dawley rats induced a three-fold increase in urinary excretion of malonaldehyde, increased hepatic ornithine decarboxylase activity from a control value of 16.8 pmol/mg/h... [Pg.701]

In this chapter, we studied the influence of spatially-hindered phenols and plant growth regulators (PGR) on the intensity of lipid peroxidation (LPO) in membranes of mitochondria. Under stress conditions, the intensity of fluorescence of LPO products in membranes of these organelles increases 3 to 4 times. Spatially-hindered phenols and PGRs decrease the LPO intensity to the control values and maintain thereby a high functional activity of mitochondria. Prevention of dysfunction of mitochondria is associated with enhancement of the resistance of plant and animal organisms to the action of stressors. [Pg.466]
