Abstract

Radish (Raphunus sativa), coriander (Coriandrum sativum), mustard (Brassica juncea), and spinach (Spinacea oleracea) plants were grown in earthen pots watered with aqueous solutions containing 0, 5, and 10 mg F/L. Fluoride (F) uptake and superoxide dismutase (SOD) activity (unit/mg protein/min) were estimated from the edible plant parts following harvest after 60 days. The values of
both entities rose with increasing F exposure in the order radish > coriander > spinach > mustard. The results indicate that plant species tolerant to F toxicity induce higher antioxidant SOD activity, which may be an adaptive reaction in plant cells to attenuate the damaging effect of reactive oxygen species (ROS) generated during F stress.

  • Effects of Fluoride on Oxidative Stress Markers of Lipid, Gene, and Protein in Rats.

    Endemic fluorosis is a systemic chronic disease caused by excessive intake of fluoride. It is widely accepted that oxidative stress is closely related to fluorosis; however, molecular mechanism of oxidative stress in fluorosis remains unclear. This study investigated the effects of fluoride (F) on oxidative stress markers of lipid, gene,

    The present study was undertaken to evaluate the cardioprotective role of (-)-epigallocatechin-gallate (EGCG) against Fluoride (F) induced oxidative stress mediated cardiotoxicity in rats. The animals exposed to F as sodium Fluoride (NaF) (25mg/kg BW) for 4 weeks exhibited a significant increase in the levels of cardiac troponins T and I

  • Protective effects of vitamins C and E against endometrial damage and oxidative stress in fluoride intoxication

    1. Fluoride (F) is an essential trace element that has protective effects against bone mineral loss. However, it becomes toxic at higher doses and induces some adverse effects on a number of physiological functions, including reproduction. The aims of this study were to examine F-induced oxidative stress that promotes production

  • Neurobehavioral and neurochemical effects in rats offspring co-exposed to arsenic and fluoride during development.

    Highlights Arsenic/Fluoride co-exposure during development causes neurobehavioral alterations in offspring. iAs/F causes delayed development of sensorimotor reflexes and produces less nociceptive response. iAs/F co-exposure increase locomotor activity. Antioxidant enzymes and neurotransmitter level are altered in the striatum area. Arsenic (iAs) and fluoride (F) are ubiquitous in the environment. All over

  • Nutrient Deficiencies Enhance Fluoride Toxicity

    It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

  • Fluoride & Oxidative Stress

    A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride's toxic effects can be ameliorated by exposure
