The present study investigates the effect of pre-treatment with Salvia miltiorrhiza ethanol extracts (SMEE) on renal function markers, immunity and antioxidant activities in renal ischemia and reperfusion (IR) rats. Wistar rat kidneys were subjected to 60 min of global ischemia at 37 °C followed by 30 min of reperfusion, and were randomly assigned into the sham, IR model and three SMEE-treated ...

this study documents the flavonoid constituents of seven salvia species in iran namely s.atropatana bunge, s. limbata c. a. mey, s. sclarea l., s. ceratophylla l., s. multicaulis vahl.,s. hydrangea dc. ex benth., and s. eremophila boiss. the studied species were collected fromtheir natural habitats in iran and were analyzed for their flavonoid constituents using twodimensionalthin layer chromat...

The efficient clearance of microbes by neutrophils requires the concerted action of reactive oxygen species and microbicidal components within leukocyte secretory granules. Rubrerythrin (Rbr) is a nonheme iron protein that protects many air-sensitive bacteria against oxidative stress. Using oxidative burst-knockout (NADPH oxidase-null) mice and an rbr gene knockout bacterial strain, we investig...

Flavones were directly alkylated at the C-3 position in moderate yields using a xanthate-based oxidative radical addition procedure. This methodology is a suitable synthetic tool for the direct substitution of the vinylic and unactivated C-H bond of the C ring of the flavone by an alkyl functionality under neutral conditions.

OBJECTIVE An erythematous response to intradermal injection of monosodium urate crystals (MSU) has been demonstrated in Behçet's syndrome (BS). To further elucidate the pathogenesis of this response, the effects of MSU on in vitro oxidative burst reaction of neutrophils and monocytes were investigated. METHODS Peripheral blood mononuclear cells from patients with Behçet's syndrome (BS), rheum...

Background: A number of medicinal plants have been used to treat various immunological diseases. Nitric oxide (NO) has an important regulatory role in the various types of inflammatory processes. Objective: To investigate the NO modulatory activity of the extracts of several medicinal plants native to Iran including Dracocephalum kotschyi, Linum persicum, Dionysia termeana, Salvia mirzayanii, F...

The alveolar macrophage (AM) oxidative burst response is an important component of microbicidal effector cell function against a variety of potential pathogens in the lungs, although the role against Pneumocystis carinii has not been fully investigated. The goals of this study were to characterize the P. carinii-mediated oxidative burst of AMs from healthy individuals, and to examine the oxidat...
