Free radical-mediated oxidation is often linked to various degenerative diseases. Biological substrates with lipids as major components are susceptible to oxygen-derived lipid peroxidation due to their composition. Lipid peroxide products act as biomarkers in evaluating the antioxidant potential of various plants and functional foods. The study focused on evaluation of the antioxidant potential...

BACKGROUND Grewia carpinifolia is a plant commonly used in the tropics to manage various central nervous system (CNS) disorders. However, despite its widespread use no scientific work has been reported to validate these claims. OBJECTIVES To evaluate the activity of G. carpinifolia as it affects behaviour using animal model. METHODS Twenty five adult Wistar rats were randomly divided into f...

Ethanolic extract of the roots of A. racemosus improved the stress tolerance in chemical writhing test and swimming endurance test at all the doses as compared to stress control group. Restraint stress induced elevation of blood glucose, triglyceride and cholesterol levels were significantly lowered by pretreatment with extract. Moreover, stress induced variations in levels of lipid peroxidatio...

OBJECTIVE The present study aimed to investigate whether graded doses of Bacopa Monniera (BM) extract could produce antidepressant-like effects in chronic unpredictable stress (CUS) induced depression in rats and its possible mechanism(s). METHODS Rats were subjected to an experimental setting of CUS. The effect of BM extract treatment in CUS-induced depression was examined using behavioral t...

Oxidative damage is one of the hallmarks of the aging process. The current study evaluated effects of two proprietary antioxidant-based ingredients, rosemary extract and spearmint extract containing carnosic acid and rosmarinic acid, respectively, on learning and memory in the SAMP8 mouse model of accelerated aging. The two rosemary extracts contained carnosic acid (60% or 10% carnosic acid) an...

The current study investigated the effect of the aqueous extract of Helicteres isora L (Sterculiaceae) bark on oxidative stress in the brains of rats during diabetes. The aqueous extract of H. isora bark was administered orally (100, 200mg=kg b.w.) and the effect of the extract on blood glucose, plasma insulin, and the levels of thiobarbituric acid reactive substances (TBARS), hydroperoxides, s...

We investigated the effect of Ginkgo biloba extract on apoptosis of brain tissues in rats with acute cerebral infarction and apoptosis-related gene expression. Rat models of acute cerebral infarction were constructed using the suture method, and randomly divided into the control group, model, and treatment groups. In the treatment group, 4 mg/kg G. biloba extract was intravenously injected into...

The present study is aimed at investigating the effect of nicotine administration on carbohydrate metabolic enzymes in the brain tissue of male albino rat. In vitro studies showed that Red grape (Vitis vinifera) has significant antioxidant activity, antimicrobial, anti-inflammatory action. Nicotine induces oxidative stress both in vivo and in vitro that causes a peroxidant/antioxidant imbalance...

Background and Aim: Learning and memory defect occurs following chronic diabetes with uncontrolled blood glucose. Ginkgo leaf extract improves brain blood flow. Also it contains antioxidant components and has shown beneficial effects in neurological diseases. In this study we investigated the effects of Ginkgo leaf extract on spatial memory impairment and hippocampal neuronal loss caused by dia...

Introduction: Recently, herbal medicine is widely used as an alternative and complementary therapy in several neurological disorders such as epilepsy. The anti-inflammatory and neuroprotective effects of Zingiber officinale or ginger have been well-documented. The present study was designed to evaluate the effects of ginger extract pre-treatment on seizures behavior, neuronal density and as...
