CONTEXT Chronic oral intake of high doses of monosodium glutamate (MSG) could be harmful to tissues and organs. Oxidative stress enhances membrane damage by lipid peroxidation and alterations of antioxidant enzymes, which affects the functional activity of organs. Antioxidant vitamins have the capacity to regulate the oxidative stress related functional and(More)
The present study evaluates the effect of long term intake of aspartame, the artificial sweetener, on liver antioxidant system and hepatocellular injury in animal model. Eighteen adult male Wistar rats, weighing 150-175 g, were randomly divided into three groups as follows: first group was given aspartame dissolved in water in a dose of 500 mg/kg b.wt.; the(More)
OBJECTIVES Arsenic trioxide (As2O3) is a potent drug for acute promyelocytic leukaemia, but its clinical trials are allied with some serious adverse events mainly cardiac functional abnormalities. So the objective of our investigation is to identify the cardioprotective action of flaxseed oil (FSO), a natural compound against As2O3 induced cardiotoxicity.(More)
Arsenic compounds have been used for medicinal purposes throughout history. Arsenic trioxide (As2O3) achieved dramatic remissions in patients with acute promyelocytic leukaemia. Unfortunately, the clinical usefulness of As2O3 has been limited by its toxicity. The present study was designed to investigate the toxic effects of As2O3 at its clinical(More)
BACKGROUND Chronic oral intake of high doses of monosodium glutamate (MSG) causes oxidative stress. Oxidative stress plays an important role in the development of cardiac dysfunction and injury. Supplementation with α-tocopherol protects the body against oxidative stress and its related complications. This study was proposed to examine the protective effect(More)
Arsenic is an environmental toxic metal implicated in human diseases. Carotenoids are the most widespread group of pigments found in nature. Astaxanthin is a xanthophylls keto carotenoid with antioxidant property and commonly found in marine environment. The purpose of this study was to examine a possible cardioprotective effect of astaxanthin against(More)
Boerhavia diffusa is a renowned edible medicinal plant extensively used against different ailments including heart diseases in the traditional system of medicine in several countries. The present study aims to evaluate the therapeutic efficacy of ethanolic extract of Boerhavia diffusa (BDE) on cardiac hypertrophy and fibrosis induced by angiotensin II (Ang(More)
Arsenic trioxide (As2O3) is a highly effective therapeutic against acute promyelocytic leukaemia, but its clinical efficacy is burdened by serious cardiac toxicity. The present study was performed to evaluate the effect of omega (ω)-3 fatty acid on As2O3-induced cardiac toxicity in in vivo and in vitro settings. In in vivo experiments, male Wistar rats were(More)
The present study investigated the effect of long-term intake of aspartame, a widely used artificial sweetener, on antioxidant defense status in the rat brain. Male Wistar rats weighing 150-175 g were randomly divided into three groups as follows: The first group was given aspartame at a dose of 500 mg/kg body weight (b.w.); the second group was given(More)
Aspartame is one of the most widely used artificial sweeteners globally. Data concerning acute toxicity of aspartame is controversial, and knowledge on its chronic effect is limited. The present study evaluates the effect of long-term intake of aspartame on serum biochemical parameters and erythrocyte antioxidant defence system in rats. Male Wistar rats,(More)
