malaria is considered a major health problem in iran. there are different methods for vector control. in this study we tested the larvicidal effects of some iranian plants. the methanolic extracts of 11 plants were prepared with percolation method. the larvicidal activities of them against malaria vector, anopheles stephensi were studied using world health organization standard method. all lc50...

this study was conducted to investigate the effects of curcuma zedoaria and zingiber zerumbet on non-specific immune responses of grouper (epinephelus coioides). fish were fed an experimental diet containing 0, 0.5, 1.0, 2.5 g/kg of c. zedoaria and z. zerumbet mixed diets twice daily for two weeks. non-specific immune parameters such as respiratory burst activity, reactive oxygen species, phago...

objective(s) seed of cucumis sativus linn. is one of the herbal remedies has been traditionally used for diabetes mellitus treatment. we studied the effect of hydroalcoholic and buthanolic extract obtained from c. sativus seeds in a model of streptozotocin (stz)-induced diabetic (type i) rats. materials and methods normal and diabetic male wistar rats (stz, 60 mg/kg, intraperitoneal) were treat...

objective(s) matricaria aurea is found abundant in iran and has large similarities in constituents especially essential oils, flavones and flavonoides as well as traditional uses to the main species; matricaria recutita l. anti-inflammatory, antioxidant and spasmolytic properties of the main species suggest that this plant may have beneficial effects on inflammatory bowel diseases so the presen...

background: diabetes mellitus is considered one of the 5 principal causes of death in the world and is recognized as a global public health issue because of its multifactorial facets affecting essential biochemical processes in the body. this study investigated the antidiabetic and antidyslipidemic activities of the aqueous extract of cochlospermum planchonii (c. planchonii) leaves in streptozo...

silver nanoparticles (agnps) are amongst the most investigated materials in nanotechnology in view of their unique physio-chemical features and applications in restorative science. their progressive usages in different fields of science besides some predominant restrictions with conventional methods for their synthesis have demanded analysts to discover green courses for their creation. biologi...

conclusions the results of our study showed that plant extracts have good antibacterial properties against pseudomonas aeruginosa and escherichia coli. objectives this research aims to discover the function of some medicine plants on pestiferous pseudomonas aeruginosa and escherichia coli in humans. materials and methods bacterial strains were obtained from a standard laboratory. the strains of...

background & aim: the plants of the greenhouse have been affected by infestation of the pest trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms and toxicity t...

a facile and green approach has been developed to synthesize silver nanoparticle (ag-nps). this was carried out by a biosynthetic route using justicia adhatoda root extract as reducing and stabilizing agent. the structure, composition, average particle size (~25 nm) and surface morphology of ag-nps were characterized by the x-ray diffraction, transmission electron microscope and atomic force mi...

objective: alpha-glucosidase, as a carbohydratase catalyses the liberation of alpha-glucose from the nonreducing end of some carbohydrates from foods in digestive tract.  consequently, retard absorption of glucose by the inhibition of carbohydrate hydrolyzing enzymes is one of the therapeutic approaches to decrease the postprandial hyperglycemia. recently, a great deal of attention has been pai...
