We investigated the effect of Euphorbia supina extract on the production of cellular reactive oxygen species (ROS) in order to evaluate its antioxidative activity. The H2O2-induced ROS generation was measured with dichlorofluorescein-diacetate (DCFH-DA) assay. The acetone+methylene chloride (A+M) and methanol (MeOH) extracts dose-dependently decreased ROS production induced by H2O2 compared to ...

Diabetes mellitus is the most common endocrine disorder that impairs glucose homeostasis resulting in severe diabetic complications including retinopathy, angiopathy, nephropathy, and neuropathy causing neurological disorders due to perturbation in utilization of glucose. Hypoglycemic activity was detected in aqueous extract of Passiflora ligularis, a traditionally used medicinal plant, using s...

At present, it is widely-known that free radicals are the causes of illness such as cancers, coronary heart disease, Alzheimer’s disease and aging. One method of protection from free radical is the consumption of antioxidant-containing foods or herbs. Several analytical methods have been used for qualitative and quantitative determination of antioxidants. This project aimed to evaluate antioxid...

a vast majority of the studies addressing the free radicals including hydroxyl radical is a damage compound of biochemical molecules such as dna, proteins and lipids. when free radicals specially hydroxyl radical are not adequately removed from the body, it may damage biological macromolecules, leading to a variety of disease occurs. therefore, the body should be protected by an enzymatic or no...

In the present study the antidiabetic potential of aqueous and ethanol extract of Cassia auriculata L. flowers was assessed in alloxan-induced diabetic rats. The phytochemical screening and antioxidant activity were made in these extracts. Antidiabetic agents (Flavonoids and phenolic acids) and free radical scavenging activity in water-soluble fraction of the ethanol extract was higher compared...

the aim of this study was to assess the efficacy and tolerability of the aqueous extract of echium amoenum in combination with ssris in patients with general anxiety disorder (gad). the study was an 8-week double-blind randomized clinical trial. thirty-seven adult outpatients who met the dsm-iv-tr criteria for gad based on the structured clinical interview participated in the trial. in this stu...

preliminary studies revealed that urtica dioica has been known as a plant that decrease blood glucose. despite the importance of this plant in herbal medicine, relatively little research has been down on effects of this plant on islets yet. the objective of the current study was to evaluate the effect of dried urtica dioica leaf alcoholic and aqueous extracts on the number and the diameter of t...

background : the study was aimed to show the effect of molecular mechanism of aqueous garlic extract (age) on expression of ifnγ and inos genes in leishmania major . methods : leishmania major promastigotes (mrho/ir/75/er) were added to the in-vitro cultured j774 cell line, the cells were incubated for 72 hours. various concentrations of garlic extract (9.25, 18.5, 37, 74, 148 mg/ml) were added...
