The present study was to evaluate the protective role of hesperidin (HDN) against iron-induced hepatic and renal toxicity in rats. Administration of iron (30 mg/kg body weight) intraperitoneally for 10 days, the levels of serum hepatic markers, renal functional markers, lipid profile, lipid peroxidation markers and iron concentration in blood were significantly (p < 0.05) increased. The toxic e...

High level of ROS (Reactive Oxygen Species), due to an increased production of oxidant species and/or a decreased efficacy of antioxidant system, can lead to oxidative stress (OS) an emerging health risk factor involved in the aging and in many diseases, either in humans or in animals. ROS are a double-edged sword – they serve as key signal molecules in physiological processes, but also have a ...

In this study we investigated the oxidative stress, antioxidants and inflammatory molecules in patients of acute myocardial infarction (AMI) with diabetes (n = 50) and non-diabetes (n = 50). Fifty healthy subjects were taken as control. The levels of plasma TBARS and ceruloplasmin levels were significantly high in diabetic and non-diabetic AMI patients as compared with control. On the other han...

Aims: The present research was done to evaluate the antioxidant activity of aqueous extract Withania somnifera (Ashwagandha) in equine. Herbal antioxidants have gained popularity due their potency and safety, oxidative stress is a condition that more prevalent horses performing physical activities.&#x0D; Methods: Twenty clinically healthy were selected equally divided into treatment control gro...

Research on the use, properties, characteristics and sources of antioxidants especially phenolic compounds, flavonoids, vitamins, synthetic chemicals and some micronutrients began in the late 18(th) century. Since then antioxidant research has received considerable attention and over a hundred thousand papers have been published on the subject. This has led to a rampant use of antioxidants in o...

Free radicals are produced through biological processes and environmental interactions. They are metabolised by the enzymatic and non-enzymatic antioxidants present in the tissues. In this study, a 90 days long feeding of high fat diet to rats, resulted in significantly elevating the lipid and oxidative stress levels of the rat liver and blood as became evident from the changes in the levels of...

Cancer has a complex etiology with multiple risk factors that involve the interplay between genetic and environmental influences. There is compelling evidence that dietary plant foods appear to be protective against certain type of cancers. Among a number of mechanistic hypotheses, diet-derived antioxidants have been proposed to contribute to explain these findings. However, contrasting results...

Oxidants are highly unstable molecules that attack every chemical substance they come into contact. Oxidants modify the macromolecules both structurally and functionally. Body has defense mechanisms against oxidants in the form of both enzymatic and non-enzymatic antioxidants. Reactive oxygen species (ROS) are a group of oxidants formed during oxygen metabolism. ROS appears to be involved in th...

The present study investigated the antilipoperoixdative and antioxidant effect of morin in normal and streptozotocin-induced diabetic Wistar rats. Diabetes as induced in rats by an intraperitoneal injection of streptozotocin. Morin was orally administered to normal and diabetic rats for a period of 45 days. In diabetic rats, thiobarbituric acid reactive substances and lipid hydroperoxides were ...
