Oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. As the antioxidant effects of some species of Pistacia have been reported, the protective effects of Pistacia vera L. gum extract (0.1-0.5 g/kg) on oxidative damage following cerebral ischemia were studied in rats. Ischemia was induced using four-vessel occlusion model and evaluated using measurement of m...

Background: Insulin resistance plays a key role in the onset of several metabolic disorders. Aim and Objectives: To determine the insulin sensitizing property of aqueous extract of Gymnema sylvestre leaves on dexamethasone induced insulin resistance in rats. Materials and Methods: Animals were divided into five groups (n=6) and the study was conducted for a period of 12 days. Insulin resistance...

introduction: previously, we demonstrated that i.p. injection of aqueous extract prepared from aerial parts of drosera spatulata (droseraceae) can induced remarkable analgesia in both phases of formalin test in rats. because, analgesia induced in acute phase of formalin test mainly mediated by activation of central analgesic mechanisms and also paragigantocellularis (pgi) nucleus is part of bra...

objective: in the present study, the effects of aqueous saffron extract (crocus sativus l.) on the acquisition and reinstatement of morphine-induced conditioned place preference (cpp) in mice were investigated. materials and methods: subcutaneous administration of morphine (40 mg/kg for four days) produced place preference. intraperitoneal administration of aqueous extract (40 and 80 mg/kg for ...

A novel dual tablet formulation for oral administration using xanthan gum as the carrier and meloxicam as a model drug has been investigated for colonspecific drug delivery using invitro methods. The tablets were evaluated for hardness, thickness, drug content uniformity, and were subjected to invitro drug release studies under conditions mimicking mouth to colon transit and the results of whic...

Gum polysaccharides are comprised of different monosaccharide units joined together by O-glycosidic linkages. The structural diversity of different polysaccharides is due to differences in degree of polymerization, monosaccharide composition, chain shapes, and linkage types. Gum polysaccharides are commonly used in both food and nonfood industries as stabilizers, thickening and gelling agents, ...

The influence of weighting agents and sucrose on gravitational separation in 1 wt % oil-in-water emulsions was studied by measuring changes in the intensity of backscattered light from the emulsions with height. Emulsions with different droplet densities were prepared by mixing weighting agents [brominated vegetable oil (BVO), ester gum (EG), damar gum (DG), or sucrose acetate isobutyrate (SAIB...

Delonix regia gum (DRG) is a natural polysaccharide obtained from the endosperm of Delonix regia seeds, chemically classified as galactomannan. The objective of the present study was to derivatise DRG to carboxymethylated Delonix regia gum (CMDRG) using non aqueous method and to overcome limitations of natural polymer viz, fall in viscosity on storage, susceptible to microbial contamination, an...

Petroleum ether (60 degrees-80 degrees C), chloroform, acetone, ethanol, aqueous and crude hot water extracts of the whole plant of C. dactylon and the two fractions of aqueous extract were tested for antihyperglycaemic activity in glucose overloaded hyperglycemic rats and in alloxan induced diabetic model at two-dose levels, 200 and 400 mg/kg (po) respectively. The aqueous extract of C. dactyl...
