OBJECTIVES Neutrophils represent the front line of human defense against infections. Immediately after stimulation, neutrophilic enzymes are activated and produce toxic mediators such as pro-inflammatory cytokines, nitric oxide (NO) and myeloperoxidase (MPO). These mediators can be toxic not only to infectious agents but also to host tissues. Because flavonoids exhibit antioxidant and anti-infl...

Reperfusion following liver ischemia results in oxidative stress leading to liver injury. The aim of this study was to investigate the combined effects of two antioxidant agents, rutin and L-arginine, in rat liver ischemia-reperfusion (I/R). Male Wistar rats were divided into five groups: 1) sham operated, 2) I/R, 3) I/R+rutin, 4) I/R+L-arginine, and 5) I/R+rutin+L-arginine. Plasmatic and hepat...

Chronic exposure of the skin to solar UV radiation induces a number of biological alterations, including a redox imbalance; therefore, there is an urgent need for skin cells protective compounds. The aim of this study was to determine the effects of natural, previously extensively examined, polyphenol with antioxidant properties - rutin, on UV-induced skin fibroblasts membrane disruption. Accor...

Alcoholism and obesity are strongly associated with several disorders including heart and liver diseases. This study evaluated the effects of rutin treatment in serum, heart and liver tissues of rats subjected to a combination of hypercaloric diet (HD) and chronic ethanol consumption. Rats were divided into three groups: Control: rats fed a standard diet and drinking water ad libitum; G1: rats ...

Rutin has anti-inflammatory, antioxidant, anti-viral, anti-tumor and immune regulatory effects. However, the neuroprotective effects of rutin in spinal cord injury are unknown. The p38 mitogen activated protein kinase (p38 MAPK) pathway is the most important member of the MAPK family that controls inflammation. We assumed that the mechanism of rutin in the repair of spinal cord injury is associ...

Accumulation of intracellular sorbitol due to increased aldose reductase (ALR2 or AKR1B1) activity has been implicated in the development of various secondary complications of diabetes. Previously we have reported that some common dietary sources such as spices, fruits and vegetables have the potential to inhibit ALR2 under in vitro conditions and in animal models. In this study, we describe th...

conclusions it seems that the preventive effects of rutin against damages caused by ida can be attributed to its ability to reduce apoptosis, which may be mediated by underexpression of caspase3 and overexpression of bcl2 genes. also, it could increase the expression of dazl that may be important in spermatogenesis. methods in the current experimental study, balb/c mice were divided into 8 grou...

The study examined the comparative rutin contents and antioxidant potentials of the two closely related Moringa species: the Ethiopian (Moringa stenopetala) and Indian Moringa (M. oleifera). It is demonstrated that M. stenopetala leaves extract was a far superior (more than five-fold better) antioxidant than M. oleifera. Rutin was the principal constituent of M. stenopetala leaves while the com...

The electrochemical behavior of ascorbic acid and rutin using a poly(L-arginine)-graphene oxide modified glassy carbon electrode (PLA-GO/GCE) has been studied by cyclic voltammetry and chronoamperometry. The modified electrode succeeds in distinguishing the electrochemical responses of ascorbic acid and rutin in a mixture solution due to its high electron transfer rate and good catalytic abilit...

Rutin is available in some foods, fruits, and vegetables. It has various beneficial medical effects making it useful in the treatment of various diseases. Rutin is available in different oral dosage forms such as tablets or capsules, widely available in the market. Rutin and many herbal medicines lack quality control due to unavailability of analytical methods. In this study, we formulated ruti...
