“…Generally, damage to liver cells will result in plasma transaminases elevation (Wolf et al, ). Furthermore, measurement of AST and ALT enzymatic activities is of clinical and toxicological importance (Singh et al, ). In the present study, the observed increase in the activities of plasma AST and ALT suggests the leakage of these enzymes from the liver to the plasma.…”

Chronic exposure to potassium bromate (KBrO ), a toxic halogen existing widely in the environment, environment through contaminated drinking water, has become a global problem of public health. The present study investigates the protective role of vanillin against KBrO induced oxidative stress, distruption in inflammatory cytokines expression, DNA damage, and histopathological changes. Adult mice were exposed orally to KBrO (2g/L of drinking water) for 2 weeks The co-administration of vanillin to the KBrO -treated mice significantly prevented the plasma transaminases increase in. Furthermore, it inhibited hepatic lipid peroxidation (malondialdehyde), advanced oxidation protein product (AOPP) and protein carbonyl (PCO) formation and attenuated the KBrO -mediated depletion of enzymatic and non enzymatic antioxidants catalase, superoxide dismutase, and glutathione peroxidase activities and glutathione level in the liver. In addition, vanillin markedly attenuated the expression levels of proinflammatory cytokines, including tumor necrosis factor-α, interleukin-1β, interleukin-6, and COX2 and prevented KBrO -induced hepatic cell alteration and necrosis, as indicated by histopathological data. DNA damage, as assessed by the alkaline comet assay, was also found to be low in the co-treated group. Thus, these findings show that vanillin acts as potent chemopreventive agent against KBrO -mediated liver oxidative stress and genotoxicity through its antioxidant properties. © 2015 Wiley Periodicals, Inc.

Mechanism of electrical conductivity (σ), mechanical properties, and γ‐ray transmission properties of ethylene propylene diene monomer (EPDM)/butadiene rubber (BR) composites have been investigated from the viewpoint of free volume (ie, open hole size). The EPDM/BR composites (100/0, 70/30, 50/50, 30/70, and 0/100) loaded with 50 phr carbon black as a reinforcing filler and irradiated with different doses (10, 30, 50, 70, and 100 kGy). The ortho‐positronium lifetime (o‐Ps) for all the composites is measured using the positron annihilation lifetime (PAL) spectroscopy. Linear attenuation coefficients are measured for unirradiated composite at 59.5 keV using 241Am γ‐source. Scan electron microscope, electrical conductivity, stress‐strain, and hardness tests are investigated for all the composites before irradiation at room temperature (25°C). The results show a good linear correlation between the open hole size evaluated by PAL spectroscopy and all of the measured properties. These correlations confirmed the important role played by the free volume (ie, is governed by the open hole size) in all of the electrical conductivity, mechanical, and transmission properties in the composite. The results status that, the composite sample EPDM/BR (0/100) may be used as a radiation resistant material or as a radiation protector for tools in high‐level radiation areas.
